-+ GNU LESSER GENERAL PUBLIC LICENSE
-+ Version 2.1, February 1999
-+
-+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
-+ Everyone is permitted to copy and distribute verbatim copies
-+ of this license document, but changing it is not allowed.
-+
-+[This is the first released version of the Lesser GPL. It also counts
-+ as the successor of the GNU Library Public License, version 2, hence
-+ the version number 2.1.]
-+
-+ Preamble
-+
-+ The licenses for most software are designed to take away your
-+freedom to share and change it. By contrast, the GNU General Public
-+Licenses are intended to guarantee your freedom to share and change
-+free software--to make sure the software is free for all its users.
-+
-+ This license, the Lesser General Public License, applies to some
-+specially designated software packages--typically libraries--of the
-+Free Software Foundation and other authors who decide to use it. You
-+can use it too, but we suggest you first think carefully about whether
-+this license or the ordinary General Public License is the better
-+strategy to use in any particular case, based on the explanations below.
-+
-+ When we speak of free software, we are referring to freedom of use,
-+not price. Our General Public Licenses are designed to make sure that
-+you have the freedom to distribute copies of free software (and charge
-+for this service if you wish); that you receive source code or can get
-+it if you want it; that you can change the software and use pieces of
-+it in new free programs; and that you are informed that you can do
-+these things.
-+
-+ To protect your rights, we need to make restrictions that forbid
-+distributors to deny you these rights or to ask you to surrender these
-+rights. These restrictions translate to certain responsibilities for
-+you if you distribute copies of the library or if you modify it.
-+
-+ For example, if you distribute copies of the library, whether gratis
-+or for a fee, you must give the recipients all the rights that we gave
-+you. You must make sure that they, too, receive or can get the source
-+code. If you link other code with the library, you must provide
-+complete object files to the recipients, so that they can relink them
-+with the library after making changes to the library and recompiling
-+it. And you must show them these terms so they know their rights.
-+
-+ We protect your rights with a two-step method: (1) we copyright the
-+library, and (2) we offer you this license, which gives you legal
-+permission to copy, distribute and/or modify the library.
-+
-+ To protect each distributor, we want to make it very clear that
-+there is no warranty for the free library. Also, if the library is
-+modified by someone else and passed on, the recipients should know
-+that what they have is not the original version, so that the original
-+author's reputation will not be affected by problems that might be
-+introduced by others.
-+
-+ Finally, software patents pose a constant threat to the existence of
-+any free program. We wish to make sure that a company cannot
-+effectively restrict the users of a free program by obtaining a
-+restrictive license from a patent holder. Therefore, we insist that
-+any patent license obtained for a version of the library must be
-+consistent with the full freedom of use specified in this license.
-+
-+ Most GNU software, including some libraries, is covered by the
-+ordinary GNU General Public License. This license, the GNU Lesser
-+General Public License, applies to certain designated libraries, and
-+is quite different from the ordinary General Public License. We use
-+this license for certain libraries in order to permit linking those
-+libraries into non-free programs.
-+
-+ When a program is linked with a library, whether statically or using
-+a shared library, the combination of the two is legally speaking a
-+combined work, a derivative of the original library. The ordinary
-+General Public License therefore permits such linking only if the
-+entire combination fits its criteria of freedom. The Lesser General
-+Public License permits more lax criteria for linking other code with
-+the library.
-+
-+ We call this license the "Lesser" General Public License because it
-+does Less to protect the user's freedom than the ordinary General
-+Public License. It also provides other free software developers Less
-+of an advantage over competing non-free programs. These disadvantages
-+are the reason we use the ordinary General Public License for many
-+libraries. However, the Lesser license provides advantages in certain
-+special circumstances.
-+
-+ For example, on rare occasions, there may be a special need to
-+encourage the widest possible use of a certain library, so that it becomes
-+a de-facto standard. To achieve this, non-free programs must be
-+allowed to use the library. A more frequent case is that a free
-+library does the same job as widely used non-free libraries. In this
-+case, there is little to gain by limiting the free library to free
-+software only, so we use the Lesser General Public License.
-+
-+ In other cases, permission to use a particular library in non-free
-+programs enables a greater number of people to use a large body of
-+free software. For example, permission to use the GNU C Library in
-+non-free programs enables many more people to use the whole GNU
-+operating system, as well as its variant, the GNU/Linux operating
-+system.
-+
-+ Although the Lesser General Public License is Less protective of the
-+users' freedom, it does ensure that the user of a program that is
-+linked with the Library has the freedom and the wherewithal to run
-+that program using a modified version of the Library.
-+
-+ The precise terms and conditions for copying, distribution and
-+modification follow. Pay close attention to the difference between a
-+"work based on the library" and a "work that uses the library". The
-+former contains code derived from the library, whereas the latter must
-+be combined with the library in order to run.
-+
-+ GNU LESSER GENERAL PUBLIC LICENSE
-+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-+
-+ 0. This License Agreement applies to any software library or other
-+program which contains a notice placed by the copyright holder or
-+other authorized party saying it may be distributed under the terms of
-+this Lesser General Public License (also called "this License").
-+Each licensee is addressed as "you".
-+
-+ A "library" means a collection of software functions and/or data
-+prepared so as to be conveniently linked with application programs
-+(which use some of those functions and data) to form executables.
-+
-+ The "Library", below, refers to any such software library or work
-+which has been distributed under these terms. A "work based on the
-+Library" means either the Library or any derivative work under
-+copyright law: that is to say, a work containing the Library or a
-+portion of it, either verbatim or with modifications and/or translated
-+straightforwardly into another language. (Hereinafter, translation is
-+included without limitation in the term "modification".)
-+
-+ "Source code" for a work means the preferred form of the work for
-+making modifications to it. For a library, complete source code means
-+all the source code for all modules it contains, plus any associated
-+interface definition files, plus the scripts used to control compilation
-+and installation of the library.
-+
-+ Activities other than copying, distribution and modification are not
-+covered by this License; they are outside its scope. The act of
-+running a program using the Library is not restricted, and output from
-+such a program is covered only if its contents constitute a work based
-+on the Library (independent of the use of the Library in a tool for
-+writing it). Whether that is true depends on what the Library does
-+and what the program that uses the Library does.
-+
-+ 1. You may copy and distribute verbatim copies of the Library's
-+complete source code as you receive it, in any medium, provided that
-+you conspicuously and appropriately publish on each copy an
-+appropriate copyright notice and disclaimer of warranty; keep intact
-+all the notices that refer to this License and to the absence of any
-+warranty; and distribute a copy of this License along with the
-+Library.
-+
-+ You may charge a fee for the physical act of transferring a copy,
-+and you may at your option offer warranty protection in exchange for a
-+fee.
-+
-+ 2. You may modify your copy or copies of the Library or any portion
-+of it, thus forming a work based on the Library, and copy and
-+distribute such modifications or work under the terms of Section 1
-+above, provided that you also meet all of these conditions:
-+
-+ a) The modified work must itself be a software library.
-+
-+ b) You must cause the files modified to carry prominent notices
-+ stating that you changed the files and the date of any change.
-+
-+ c) You must cause the whole of the work to be licensed at no
-+ charge to all third parties under the terms of this License.
-+
-+ d) If a facility in the modified Library refers to a function or a
-+ table of data to be supplied by an application program that uses
-+ the facility, other than as an argument passed when the facility
-+ is invoked, then you must make a good faith effort to ensure that,
-+ in the event an application does not supply such function or
-+ table, the facility still operates, and performs whatever part of
-+ its purpose remains meaningful.
-+
-+ (For example, a function in a library to compute square roots has
-+ a purpose that is entirely well-defined independent of the
-+ application. Therefore, Subsection 2d requires that any
-+ application-supplied function or table used by this function must
-+ be optional: if the application does not supply it, the square
-+ root function must still compute square roots.)
-+
-+These requirements apply to the modified work as a whole. If
-+identifiable sections of that work are not derived from the Library,
-+and can be reasonably considered independent and separate works in
-+themselves, then this License, and its terms, do not apply to those
-+sections when you distribute them as separate works. But when you
-+distribute the same sections as part of a whole which is a work based
-+on the Library, the distribution of the whole must be on the terms of
-+this License, whose permissions for other licensees extend to the
-+entire whole, and thus to each and every part regardless of who wrote
-+it.
-+
-+Thus, it is not the intent of this section to claim rights or contest
-+your rights to work written entirely by you; rather, the intent is to
-+exercise the right to control the distribution of derivative or
-+collective works based on the Library.
-+
-+In addition, mere aggregation of another work not based on the Library
-+with the Library (or with a work based on the Library) on a volume of
-+a storage or distribution medium does not bring the other work under
-+the scope of this License.
-+
-+ 3. You may opt to apply the terms of the ordinary GNU General Public
-+License instead of this License to a given copy of the Library. To do
-+this, you must alter all the notices that refer to this License, so
-+that they refer to the ordinary GNU General Public License, version 2,
-+instead of to this License. (If a newer version than version 2 of the
-+ordinary GNU General Public License has appeared, then you can specify
-+that version instead if you wish.) Do not make any other change in
-+these notices.
-+
-+ Once this change is made in a given copy, it is irreversible for
-+that copy, so the ordinary GNU General Public License applies to all
-+subsequent copies and derivative works made from that copy.
-+
-+ This option is useful when you wish to copy part of the code of
-+the Library into a program that is not a library.
-+
-+ 4. You may copy and distribute the Library (or a portion or
-+derivative of it, under Section 2) in object code or executable form
-+under the terms of Sections 1 and 2 above provided that you accompany
-+it with the complete corresponding machine-readable source code, which
-+must be distributed under the terms of Sections 1 and 2 above on a
-+medium customarily used for software interchange.
-+
-+ If distribution of object code is made by offering access to copy
-+from a designated place, then offering equivalent access to copy the
-+source code from the same place satisfies the requirement to
-+distribute the source code, even though third parties are not
-+compelled to copy the source along with the object code.
-+
-+ 5. A program that contains no derivative of any portion of the
-+Library, but is designed to work with the Library by being compiled or
-+linked with it, is called a "work that uses the Library". Such a
-+work, in isolation, is not a derivative work of the Library, and
-+therefore falls outside the scope of this License.
-+
-+ However, linking a "work that uses the Library" with the Library
-+creates an executable that is a derivative of the Library (because it
-+contains portions of the Library), rather than a "work that uses the
-+library". The executable is therefore covered by this License.
-+Section 6 states terms for distribution of such executables.
-+
-+ When a "work that uses the Library" uses material from a header file
-+that is part of the Library, the object code for the work may be a
-+derivative work of the Library even though the source code is not.
-+Whether this is true is especially significant if the work can be
-+linked without the Library, or if the work is itself a library. The
-+threshold for this to be true is not precisely defined by law.
-+
-+ If such an object file uses only numerical parameters, data
-+structure layouts and accessors, and small macros and small inline
-+functions (ten lines or less in length), then the use of the object
-+file is unrestricted, regardless of whether it is legally a derivative
-+work. (Executables containing this object code plus portions of the
-+Library will still fall under Section 6.)
-+
-+ Otherwise, if the work is a derivative of the Library, you may
-+distribute the object code for the work under the terms of Section 6.
-+Any executables containing that work also fall under Section 6,
-+whether or not they are linked directly with the Library itself.
-+
-+ 6. As an exception to the Sections above, you may also combine or
-+link a "work that uses the Library" with the Library to produce a
-+work containing portions of the Library, and distribute that work
-+under terms of your choice, provided that the terms permit
-+modification of the work for the customer's own use and reverse
-+engineering for debugging such modifications.
-+
-+ You must give prominent notice with each copy of the work that the
-+Library is used in it and that the Library and its use are covered by
-+this License. You must supply a copy of this License. If the work
-+during execution displays copyright notices, you must include the
-+copyright notice for the Library among them, as well as a reference
-+directing the user to the copy of this License. Also, you must do one
-+of these things:
-+
-+ a) Accompany the work with the complete corresponding
-+ machine-readable source code for the Library including whatever
-+ changes were used in the work (which must be distributed under
-+ Sections 1 and 2 above); and, if the work is an executable linked
-+ with the Library, with the complete machine-readable "work that
-+ uses the Library", as object code and/or source code, so that the
-+ user can modify the Library and then relink to produce a modified
-+ executable containing the modified Library. (It is understood
-+ that the user who changes the contents of definitions files in the
-+ Library will not necessarily be able to recompile the application
-+ to use the modified definitions.)
-+
-+ b) Use a suitable shared library mechanism for linking with the
-+ Library. A suitable mechanism is one that (1) uses at run time a
-+ copy of the library already present on the user's computer system,
-+ rather than copying library functions into the executable, and (2)
-+ will operate properly with a modified version of the library, if
-+ the user installs one, as long as the modified version is
-+ interface-compatible with the version that the work was made with.
-+
-+ c) Accompany the work with a written offer, valid for at
-+ least three years, to give the same user the materials
-+ specified in Subsection 6a, above, for a charge no more
-+ than the cost of performing this distribution.
-+
-+ d) If distribution of the work is made by offering access to copy
-+ from a designated place, offer equivalent access to copy the above
-+ specified materials from the same place.
-+
-+ e) Verify that the user has already received a copy of these
-+ materials or that you have already sent this user a copy.
-+
-+ For an executable, the required form of the "work that uses the
-+Library" must include any data and utility programs needed for
-+reproducing the executable from it. However, as a special exception,
-+the materials to be distributed need not include anything that is
-+normally distributed (in either source or binary form) with the major
-+components (compiler, kernel, and so on) of the operating system on
-+which the executable runs, unless that component itself accompanies
-+the executable.
-+
-+ It may happen that this requirement contradicts the license
-+restrictions of other proprietary libraries that do not normally
-+accompany the operating system. Such a contradiction means you cannot
-+use both them and the Library together in an executable that you
-+distribute.
-+
-+ 7. You may place library facilities that are a work based on the
-+Library side-by-side in a single library together with other library
-+facilities not covered by this License, and distribute such a combined
-+library, provided that the separate distribution of the work based on
-+the Library and of the other library facilities is otherwise
-+permitted, and provided that you do these two things:
-+
-+ a) Accompany the combined library with a copy of the same work
-+ based on the Library, uncombined with any other library
-+ facilities. This must be distributed under the terms of the
-+ Sections above.
-+
-+ b) Give prominent notice with the combined library of the fact
-+ that part of it is a work based on the Library, and explaining
-+ where to find the accompanying uncombined form of the same work.
-+
-+ 8. You may not copy, modify, sublicense, link with, or distribute
-+the Library except as expressly provided under this License. Any
-+attempt otherwise to copy, modify, sublicense, link with, or
-+distribute the Library is void, and will automatically terminate your
-+rights under this License. However, parties who have received copies,
-+or rights, from you under this License will not have their licenses
-+terminated so long as such parties remain in full compliance.
-+
-+ 9. You are not required to accept this License, since you have not
-+signed it. However, nothing else grants you permission to modify or
-+distribute the Library or its derivative works. These actions are
-+prohibited by law if you do not accept this License. Therefore, by
-+modifying or distributing the Library (or any work based on the
-+Library), you indicate your acceptance of this License to do so, and
-+all its terms and conditions for copying, distributing or modifying
-+the Library or works based on it.
-+
-+ 10. Each time you redistribute the Library (or any work based on the
-+Library), the recipient automatically receives a license from the
-+original licensor to copy, distribute, link with or modify the Library
-+subject to these terms and conditions. You may not impose any further
-+restrictions on the recipients' exercise of the rights granted herein.
-+You are not responsible for enforcing compliance by third parties with
-+this License.
-+
-+ 11. If, as a consequence of a court judgment or allegation of patent
-+infringement or for any other reason (not limited to patent issues),
-+conditions are imposed on you (whether by court order, agreement or
-+otherwise) that contradict the conditions of this License, they do not
-+excuse you from the conditions of this License. If you cannot
-+distribute so as to satisfy simultaneously your obligations under this
-+License and any other pertinent obligations, then as a consequence you
-+may not distribute the Library at all. For example, if a patent
-+license would not permit royalty-free redistribution of the Library by
-+all those who receive copies directly or indirectly through you, then
-+the only way you could satisfy both it and this License would be to
-+refrain entirely from distribution of the Library.
-+
-+If any portion of this section is held invalid or unenforceable under any
-+particular circumstance, the balance of the section is intended to apply,
-+and the section as a whole is intended to apply in other circumstances.
-+
-+It is not the purpose of this section to induce you to infringe any
-+patents or other property right claims or to contest validity of any
-+such claims; this section has the sole purpose of protecting the
-+integrity of the free software distribution system which is
-+implemented by public license practices. Many people have made
-+generous contributions to the wide range of software distributed
-+through that system in reliance on consistent application of that
-+system; it is up to the author/donor to decide if he or she is willing
-+to distribute software through any other system and a licensee cannot
-+impose that choice.
-+
-+This section is intended to make thoroughly clear what is believed to
-+be a consequence of the rest of this License.
-+
-+ 12. If the distribution and/or use of the Library is restricted in
-+certain countries either by patents or by copyrighted interfaces, the
-+original copyright holder who places the Library under this License may add
-+an explicit geographical distribution limitation excluding those countries,
-+so that distribution is permitted only in or among countries not thus
-+excluded. In such case, this License incorporates the limitation as if
-+written in the body of this License.
-+
-+ 13. The Free Software Foundation may publish revised and/or new
-+versions of the Lesser General Public License from time to time.
-+Such new versions will be similar in spirit to the present version,
-+but may differ in detail to address new problems or concerns.
-+
-+Each version is given a distinguishing version number. If the Library
-+specifies a version number of this License which applies to it and
-+"any later version", you have the option of following the terms and
-+conditions either of that version or of any later version published by
-+the Free Software Foundation. If the Library does not specify a
-+license version number, you may choose any version ever published by
-+the Free Software Foundation.
-+
-+ 14. If you wish to incorporate parts of the Library into other free
-+programs whose distribution conditions are incompatible with these,
-+write to the author to ask for permission. For software which is
-+copyrighted by the Free Software Foundation, write to the Free
-+Software Foundation; we sometimes make exceptions for this. Our
-+decision will be guided by the two goals of preserving the free status
-+of all derivatives of our free software and of promoting the sharing
-+and reuse of software generally.
-+
-+ NO WARRANTY
-+
-+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-+
-+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-+DAMAGES.
-+
-+ END OF TERMS AND CONDITIONS
-+
-+ How to Apply These Terms to Your New Libraries
-+
-+ If you develop a new library, and you want it to be of the greatest
-+possible use to the public, we recommend making it free software that
-+everyone can redistribute and change. You can do so by permitting
-+redistribution under these terms (or, alternatively, under the terms of the
-+ordinary General Public License).
-+
-+ To apply these terms, attach the following notices to the library. It is
-+safest to attach them to the start of each source file to most effectively
-+convey the exclusion of warranty; and each file should have at least the
-+"copyright" line and a pointer to where the full notice is found.
-+
-+ <one line to give the library's name and a brief idea of what it does.>

-+ * @defgroup lavc_encdec send/receive encoding and decoding API overview
-+ * @{
-+ *
-+ * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
-+ * avcodec_receive_packet() functions provide an encode/decode API, which
-+ * decouples input and output.
-+ *
-+ * The API is very similar for encoding/decoding and audio/video, and works
as
-+ * follows:
-+ * - Set up and open the AVCodecContext as usual.
-+ * - Send valid input:
-+ * - For decoding, call avcodec_send_packet() to give the decoder raw
-+ * compressed data in an AVPacket.
-+ * - For encoding, call avcodec_send_frame() to give the encoder an
AVFrame
-+ * containing uncompressed audio or video.
-+ * In both cases, it is recommended that AVPackets and AVFrames are
-+ * refcounted, or libavcodec might have to copy the input data.
(libavformat
-+ * always returns refcounted AVPackets, and av_frame_get_buffer()
allocates
-+ * refcounted AVFrames.)
-+ * - Receive output in a loop. Periodically call one of the
avcodec_receive_*()
-+ * functions and process their output:
-+ * - For decoding, call avcodec_receive_frame(). On success, it will
return
-+ * an AVFrame containing uncompressed audio or video data.
-+ * - For encoding, call avcodec_receive_packet(). On success, it will
return
-+ * an AVPacket with a compressed frame.
-+ * Repeat this call until it returns AVERROR(EAGAIN) or an error. The
-+ * AVERROR(EAGAIN) return value means that new input data is required to
-+ * return new output. In this case, continue with sending input. For each
-+ * input frame/packet, the codec will typically return 1 output
frame/packet,
-+ * but it can also be 0 or more than 1.
-+ *
-+ * At the beginning of decoding or encoding, the codec might accept multiple
-+ * input frames/packets without returning a frame, until its internal
buffers
-+ * are filled. This situation is handled transparently if you follow the
steps
-+ * outlined above.
-+ *
-+ * In theory, sending input can result in EAGAIN - this should happen only
if
-+ * not all output was received. You can use this to structure alternative
decode
-+ * or encode loops other than the one suggested above. For example, you
could
-+ * try sending new input on each iteration, and try to receive output if
that
-+ * returns EAGAIN.
-+ *
-+ * End of stream situations. These require "flushing" (aka draining) the
codec,
-+ * as the codec might buffer multiple frames or packets internally for
-+ * performance or out of necessity (consider B-frames).
-+ * This is handled as follows:
-+ * - Instead of valid input, send NULL to the avcodec_send_packet()
(decoding)
-+ * or avcodec_send_frame() (encoding) functions. This will enter draining
-+ * mode.
-+ * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
-+ * (encoding) in a loop until AVERROR_EOF is returned. The functions will
-+ * not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
-+ * - Before decoding can be resumed again, the codec has to be reset with
-+ * avcodec_flush_buffers().
-+ *
-+ * Using the API as outlined above is highly recommended. But it is also
-+ * possible to call functions outside of this rigid schema. For example,
you can
-+ * call avcodec_send_packet() repeatedly without calling
-+ * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
-+ * until the codec's internal buffer has been filled up (which is typically
of
-+ * size 1 per output frame, after initial input), and then reject input with
-+ * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but
to
-+ * read at least some output.
-+ *
-+ * Not all codecs will follow a rigid and predictable dataflow; the only
-+ * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call
on
-+ * one end implies that a receive/send call on the other end will succeed,
or
-+ * at least will not fail with AVERROR(EAGAIN). In general, no codec will
-+ * permit unlimited buffering of input or output.
-+ *
-+ * This API replaces the following legacy functions:
-+ * - avcodec_decode_video2() and avcodec_decode_audio4():
-+ * Use avcodec_send_packet() to feed input to the decoder, then use
-+ * avcodec_receive_frame() to receive decoded frames after each packet.
-+ * Unlike with the old video decoding API, multiple frames might result
from
-+ * a packet. For audio, splitting the input packet into frames by
partially
-+ * decoding packets becomes transparent to the API user. You never need to
-+ * feed an AVPacket to the API twice (unless it is rejected with
AVERROR(EAGAIN) - then
-+ * no data was read from the packet).
-+ * Additionally, sending a flush/draining packet is required only once.
-+ * - avcodec_encode_video2()/avcodec_encode_audio2():
-+ * Use avcodec_send_frame() to feed input to the encoder, then use
-+ * avcodec_receive_packet() to receive encoded packets.
-+ * Providing user-allocated buffers for avcodec_receive_packet() is not
-+ * possible.
-+ * - The new API does not handle subtitles yet.
-+ *
-+ * Mixing new and old function calls on the same AVCodecContext is not
allowed,
-+ * and will result in undefined behavior.
-+ *
-+ * Some codecs might require using the new API; using the old API will
return
-+ * an error when calling it. All codecs support the new API.
-+ *
-+ * A codec is not allowed to return AVERROR(EAGAIN) for both sending and
receiving. This
-+ * would be an invalid state, which could put the codec user into an endless
-+ * loop. The API has no concept of time either: it cannot happen that
trying to
-+ * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call
1 second
-+ * later accepts the packet (with no other receive/flush API calls
involved).
-+ * The API is a strict state machine, and the passage of time is not
supposed
-+ * to influence it. Some timing-dependent behavior might still be deemed
-+ * acceptable in certain cases. But it must never result in both
send/receive
-+ * returning EAGAIN at the same time at any point. It must also absolutely
be
-+ * avoided that the current state is "unstable" and can "flip-flop" between
-+ * the send/receive APIs allowing progress. For example, it's not allowed
that
-+ * the codec randomly decides that it actually wants to consume a packet now
-+ * instead of returning a frame, after it just returned AVERROR(EAGAIN) on
an
-+ * avcodec_send_packet() call.

is
-+ * a helper for preparing a AVHWFramesContext for
AVCodecContext.hw_frames_ctx.
-+ * This API is for decoding with certain hardware acceleration modes/APIs
only.
-+ *
-+ * The returned AVHWFramesContext is not initialized. The caller must do
this
-+ * with av_hwframe_ctx_init().
-+ *
-+ * Calling this function is not a requirement, but makes it simpler to avoid
-+ * codec or hardware API specific details when manually allocating frames.
-+ *
-+ * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
-+ * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
-+ * it unnecessary to call this function or having to care about
-+ * AVHWFramesContext initialization at all.
-+ *
-+ * There are a number of requirements for calling this function:
-+ *
-+ * - It must be called from get_format with the same avctx parameter that
was
-+ * passed to get_format. Calling it outside of get_format is not allowed,
and
-+ * can trigger undefined behavior.
-+ * - The function is not always supported (see description of return
values).
-+ * Even if this function returns successfully, hwaccel initialization
could
-+ * fail later. (The degree to which implementations check whether the
stream
-+ * is actually supported varies. Some do this check only after the user's
-+ * get_format callback returns.)
-+ * - The hw_pix_fmt must be one of the choices suggested by get_format. If
the
-+ * user decides to use a AVHWFramesContext prepared with this API
function,
-+ * the user must return the same hw_pix_fmt from get_format.
-+ * - The device_ref passed to this function must support the given
hw_pix_fmt.
-+ * - After calling this API function, it is the user's responsibility to
-+ * initialize the AVHWFramesContext (returned by the out_frames_ref
parameter),
-+ * and to set AVCodecContext.hw_frames_ctx to it. If done, this must be
done
-+ * before returning from get_format (this is implied by the normal
-+ * AVCodecContext.hw_frames_ctx API rules).
-+ * - The AVHWFramesContext parameters may change every time time get_format
is
-+ * called. Also, AVCodecContext.hw_frames_ctx is reset before get_format.
So
-+ * you are inherently required to go through this process again on every
-+ * get_format call.
-+ * - It is perfectly possible to call this function without actually using
-+ * the resulting AVHWFramesContext. One use-case might be trying to reuse
a
-+ * previously initialized AVHWFramesContext, and calling this API function
-+ * only to test whether the required frame parameters have changed.
-+ * - Fields that use dynamically allocated values of any kind must not be
set
-+ * by the user unless setting them is explicitly allowed by the
documentation.
-+ * If the user sets AVHWFramesContext.free and
AVHWFramesContext.user_opaque,
-+ * the new free callback must call the potentially set previous free
callback.
-+ * This API call may set any dynamically allocated fields, including the
free
-+ * callback.
-+ *
-+ * The function will set at least the following fields on AVHWFramesContext
-+ * (potentially more, depending on hwaccel API):
-+ *
-+ * - All fields set by av_hwframe_ctx_alloc().
-+ * - Set the format field to hw_pix_fmt.
-+ * - Set the sw_format field to the most suited and most versatile format.
(An
-+ * implication is that this will prefer generic formats over opaque
formats
-+ * with arbitrary restrictions, if possible.)
-+ * - Set the width/height fields to the coded frame size, rounded up to the
-+ * API-specific minimum alignment.
-+ * - Only _if_ the hwaccel requires a pre-allocated pool: set the
initial_pool_size
-+ * field to the number of maximum reference surfaces possible with the
codec,
-+ * plus 1 surface for the user to work (meaning the user can safely
reference
-+ * at most 1 decoded surface at a time), plus additional buffering
introduced
-+ * by frame threading. If the hwaccel does not require pre-allocation, the
-+ * field is left to 0, and the decoder will allocate new surfaces on
demand
-+ * during decoding.
-+ * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
-+ * hardware API.
-+ *
-+ * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(),
but
-+ * with basic frame parameters set.
-+ *
-+ * The function is stateless, and does not change the AVCodecContext or the
-+ * device_ref AVHWDeviceContext.
-+ *
-+ * @param avctx The context which is currently calling get_format, and which
-+ * implicitly contains all state needed for filling the
returned
-+ * AVHWFramesContext properly.
-+ * @param device_ref A reference to the AVHWDeviceContext describing the
device
-+ * which will be used by the hardware decoder.
-+ * @param hw_pix_fmt The hwaccel format you are going to return from
get_format.
-+ * @param out_frames_ref On success, set to a reference to an
_uninitialized_
-+ * AVHWFramesContext, created from the given
device_ref.
-+ * Fields will be set to values required for decoding.
-+ * Not changed if an error is returned.
-+ * @return zero on success, a negative value on error. The following error
codes
-+ * have special semantics:
-+ * AVERROR(ENOENT): the decoder does not support this functionality.
Setup
-+ * is always manual, or it is a decoder which does not
-+ * support setting AVCodecContext.hw_frames_ctx at
all,
-+ * or it is a software format.

-+ *
-+ * Each of the FFmpeg libraries contains a version.h header, which defines a
-+ * major, minor and micro version number with the
-+ * <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major
version
-+ * number is incremented with backward incompatible changes - e.g. removing
-+ * parts of the public API, reordering public struct members, etc. The minor
-+ * version number is incremented for backward compatible API changes or
major
-+ * new features - e.g. adding a new public function or a new decoder. The
micro
-+ * version number is incremented for smaller changes that a calling program
-+ * might still want to check for - e.g. changing behavior in a previously
-+ * unspecified situation.
-+ *
-+ * FFmpeg guarantees backward API and ABI compatibility for each library as
long
-+ * as its major version number is unchanged. This means that no public
symbols
-+ * will be removed or renamed. Types and names of the public struct members
and
-+ * values of public macros and enums will remain the same (unless they were
-+ * explicitly declared as not part of the public API). Documented behavior
will
-+ * not change.
-+ *
-+ * In other words, any correct program that works with a given FFmpeg
snapshot
-+ * should work just as well without any changes with any later snapshot
with the
-+ * same major versions. This applies to both rebuilding the program against
new
-+ * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a
program
-+ * links against.
-+ *
-+ * However, new public symbols may be added and new members may be appended
to
-+ * public structs whose size is not part of public ABI (most public structs
in
-+ * FFmpeg). New macros and enum values may be added. Behavior in
undocumented
-+ * situations may change slightly (and be documented). All those are
accompanied
-+ * by an entry in doc/APIchanges and incrementing either the minor or micro
-+ * version number.

-+ * AVBuffer is an API for reference-counted data buffers.
-+ *
-+ * There are two core objects in this API -- AVBuffer and AVBufferRef.
AVBuffer
-+ * represents the data buffer itself; it is opaque and not meant to be
accessed
-+ * by the caller directly, but only through AVBufferRef. However, the
caller may
-+ * e.g. compare two AVBuffer pointers to check whether two different
references
-+ * are describing the same data buffer. AVBufferRef represents a single
-+ * reference to an AVBuffer and it is the object that may be manipulated by
the
-+ * caller directly.
-+ *
-+ * There are two functions provided for creating a new AVBuffer with a
single
-+ * reference -- av_buffer_alloc() to just allocate a new buffer, and
-+ * av_buffer_create() to wrap an existing array in an AVBuffer. From an
existing
-+ * reference, additional references may be created with av_buffer_ref().
-+ * Use av_buffer_unref() to free a reference (this will automatically free
the
-+ * data once all the references are freed).
-+ *
-+ * The convention throughout this API and the rest of FFmpeg is such that
the
-+ * buffer is considered writable if there exists only one reference to it
(and
-+ * it has not been marked as read-only). The av_buffer_is_writable()
function is
-+ * provided to check whether this is true and av_buffer_make_writable() will
-+ * automatically create a new writable buffer when necessary.
-+ * Of course nothing prevents the calling code from violating this
convention,
-+ * however that is safe only when all the existing references are under its
-+ * control.
-+ *
-+ * @note Referencing and unreferencing the buffers is thread-safe and thus
-+ * may be done from multiple threads simultaneously without any need for
-+ * additional locking.

-+ *
-+ * Utilities to make an array grow when needed.
-+ *
-+ * Sometimes, the programmer would want to have an array that can grow when
-+ * needed. The libavutil dynamic array utilities fill that need.
-+ *
-+ * libavutil supports two systems of appending elements onto a dynamically
-+ * allocated array, the first one storing the pointer to the value in the
-+ * array, and the second storing the value directly. In both systems, the
-+ * caller is responsible for maintaining a variable containing the length of
-+ * the array, as well as freeing of the array after use.
-+ *
-+ * The first system stores pointers to values in a block of dynamically
-+ * allocated memory. Since only pointers are stored, the function does not
need
-+ * to know the size of the type. Both av_dynarray_add() and
-+ * av_dynarray_add_nofree() implement this system.
-+ *
-+ * @code
-+ * type **array = NULL; //< an array of pointers to values
-+ * int nb = 0; //< a variable to keep track of the length of the
array
-+ *
-+ * type to_be_added = ...;

-+ * // &to_be_added2 == array[1]
-+ *
-+ * av_freep(&array);
-+ * @endcode
-+ *
-+ * The second system stores the value directly in a block of memory. As a
-+ * result, the function has to know the size of the type. av_dynarray2_add()
