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.

(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,

This is meant to get called from the get_format callback, and 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.
