Each video element based on MediaDecoder has a state machine to manage
its play state and keep the current frame up to date. All state machines
share time in a single shared thread. Each decoder also has a TaskQueue
running in a SharedThreadPool to decode audio and video data.
Each decoder also has a thread to push decoded audio
to the hardware. This thread is not created until playback starts, but
currently is not destroyed when paused, only when playback ends.
The decoder owns the resources for downloading the media file, and the
high level state. It holds an owning reference to the state machine that
owns all the resources related to decoding data, and manages the low level
decoding operations and A/V sync.
Each state machine runs on the shared state machine thread. Every time some
action is required for a state machine, it is scheduled to run on the shared
the state machine thread. The state machine runs one "cycle" on the state
machine thread, and then returns. If necessary, it will schedule itself to
run again in future. While running this cycle, it must not block the
thread, as other state machines' events may need to run. State shared
between a state machine's threads is synchronised via the monitor owned
by its MediaDecoder object.
The Main thread controls the decode state machine by setting the value
of a mPlayState variable and notifying on the monitor based on the
high level player actions required (Seek, Pause, Play, etc).
The player states are the states requested by the client through the
DOM API. They represent the desired state of the player, while the
decoder's state represents the actual state of the decoder.
The high level state of the player is maintained via a PlayState value.
It can have the following states:
START
The decoder has been initialized but has no resource loaded.
PAUSED
A request via the API has been received to pause playback.
LOADING
A request via the API has been received to load a resource.
PLAYING
A request via the API has been received to start playback.
SEEKING
A request via the API has been received to start seeking.
COMPLETED
Playback has completed.
SHUTDOWN
The decoder is about to be destroyed.
State transition occurs when the Media Element calls the Play, Seek,
etc methods on the MediaDecoder object. When the transition
occurs MediaDecoder then calls the methods on the decoder state
machine object to cause it to behave as required by the play state.
State transitions will likely schedule the state machine to run to
affect the change.
An implementation of the MediaDecoderStateMachine class is the event
that gets dispatched to the state machine thread. Each time the event is run,
the state machine must cycle the state machine once, and then return.
The state machine has the following states:
DECODING_METADATA
The media headers are being loaded, and things like framerate, etc are
being determined.
DECODING_FIRSTFRAME
The first frame of audio/video data is being decoded.
DECODING
The decode has started. If the PlayState is PLAYING, the decode thread
should be alive and decoding video and audio frame, the audio thread
should be playing audio, and the state machine should run periodically
to update the video frames being displayed.
SEEKING
A seek operation is in progress. The decode thread should be seeking.
BUFFERING
Decoding is paused while data is buffered for smooth playback. If playback
is paused (PlayState transitions to PAUSED) we'll destory the decode thread.
COMPLETED
The resource has completed decoding, but possibly not finished playback.
The decode thread will be destroyed. Once playback finished, the audio
thread will also be destroyed.
SHUTDOWN
The decoder object and its state machine are about to be destroyed.
Once the last state machine has been destroyed, the shared state machine
thread will also be destroyed. It will be recreated later if needed.
The following result in state transitions.
Shutdown()
Clean up any resources the MediaDecoderStateMachine owns.
Play()
Start decoding and playback of media data.
Buffer
This is not user initiated. It occurs when the
available data in the stream drops below a certain point.
Complete
This is not user initiated. It occurs when the
stream is completely decoded.
Seek(double)
Seek to the time position given in the resource.

The following represents the states that the MediaDecoder object
can be in, and the valid states the MediaDecoderStateMachine can be in at that
time:
player LOADING decoder DECODING_METADATA, DECODING_FIRSTFRAME
player PLAYING decoder DECODING, BUFFERING, SEEKING, COMPLETED
player PAUSED decoder DECODING, BUFFERING, SEEKING, COMPLETED
player SEEKING decoder SEEKING
player COMPLETED decoder SHUTDOWN
player SHUTDOWN decoder SHUTDOWN
The general sequence of events is:
1) The video element calls Load on MediaDecoder. This creates the
state machine and starts the channel for downloading the
file. It instantiates and schedules the MediaDecoderStateMachine. The
high level LOADING state is entered, which results in the decode
thread being created and starting to decode metadata. These are
the headers that give the video size, framerate, etc. Load() returns
immediately to the calling video element.
2) When the metadata has been loaded by the decode thread, the state machine
will call a method on the video element object to inform it that this
step is done, so it can do the things required by the video specification
at this stage. The decode thread then continues to decode the first frame
of data.
3) When the first frame of data has been successfully decoded the state
machine calls a method on the video element object to inform it that
this step has been done, once again so it can do the required things
by the video specification at this stage.
This results in the high level state changing to PLAYING or PAUSED
depending on any user action that may have occurred.
While the play state is PLAYING, the decode thread will decode
data, and the audio thread will push audio data to the hardware to
be played. The state machine will run periodically on the shared
state machine thread to ensure video frames are played at the
correct time; i.e. the state machine manages A/V sync.
The Shutdown method on MediaDecoder closes the download channel, and
signals to the state machine that it should shutdown. The state machine
shuts down asynchronously, and will release the owning reference to the
state machine once its threads are shutdown.
The owning object of a MediaDecoder object *MUST* call Shutdown when
destroying the MediaDecoder object.

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.>

Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your

* @section ffmpeg_intro Introduction
*
* This document describes the usage of the different libraries
* provided by FFmpeg.
*
* @li @ref libavc "libavcodec" encoding/decoding library
* @li @ref lavfi "libavfilter" graph-based frame editing library
* @li @ref libavf "libavformat" I/O and muxing/demuxing library
* @li @ref lavd "libavdevice" special devices muxing/demuxing library
* @li @ref lavu "libavutil" common utility library
* @li @ref lswr "libswresample" audio resampling, format conversion and mixing
* @li @ref lpp "libpostproc" post processing library
* @li @ref libsws "libswscale" color conversion and scaling library
*
* @section ffmpeg_versioning Versioning and compatibility
*
* 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.
*
* @note Two different references to the same buffer can point to different
* parts of the buffer (i.e. their AVBufferRef.data will not be equal).

* frames).
*
* At the beginning, the user must call av_buffer_pool_init() to create the

* unreferenced, it is returned to the pool instead of being freed and will be
* reused for subsequent av_buffer_pool_get() calls.
*
* When the caller is done with the pool and no longer needs to allocate any new
* buffers, av_buffer_pool_uninit() must be called to mark the pool as freeable.
* Once all the buffers are released, it will automatically be freed.
