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.

(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. -+ * @} -+ */ -+ -+/** -+ * @defgroup lavc_core Core functions/structures. -+ * @ingroup libavc -+ * -+ * Basic definitions, functions for querying libavcodec capabilities,

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.

(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.
