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

* Each buffer must be reference-counted using the AVBuffer API (see description
* of buf[] below).
*
* The following fields will be set in the frame before this callback is
* called:
* - format
* - width, height (video only)
* - sample_rate, channel_layout, nb_samples (audio only)
* Their values may differ from the corresponding values in
* AVCodecContext. This callback must use the frame values, not the codec
* context values, to calculate the required buffer size.
*
* This callback must fill the following fields in the frame:
* - data[]
* - linesize[]
* - extended_data:
* * if the data is planar audio with more than 8 channels, then this
* callback must allocate and fill extended_data to contain all pointers
* to all data planes. data[] must hold as many pointers as it can.
* extended_data must be allocated with av_malloc() and will be freed in
* av_frame_unref().
* * otherwise extended_data must point to data
* - buf[] must contain one or more pointers to AVBufferRef structures. Each of
* the frame's data and extended_data pointers must be contained in these. That
* is, one AVBufferRef for each allocated chunk of memory, not necessarily one
* AVBufferRef per data[] entry. See: av_buffer_create(), av_buffer_alloc(),
* and av_buffer_ref().
* - extended_buf and nb_extended_buf must be allocated with av_malloc() by
* this callback and filled with the extra buffers if there are more
* buffers than buf[] can hold. extended_buf will be freed in
* av_frame_unref().
*
* If AV_CODEC_CAP_DR1 is not set then get_buffer2() must call
* avcodec_default_get_buffer2() instead of providing buffers allocated by
* some other means.
*
* Each data plane must be aligned to the maximum required by the target
* CPU.
*
* @see avcodec_default_get_buffer2()
*
* Video:
*
* If AV_GET_BUFFER_FLAG_REF is set in flags then the frame may be reused
* (read and/or written to if it is writable) later by libavcodec.
*
* avcodec_align_dimensions2() should be used to find the required width and
* height, as they normally need to be rounded up to the next multiple of 16.
*
* Some decoders do not support linesizes changing between frames.
*
* If frame multithreading is used and thread_safe_callbacks is set,
* this callback may be called from a different thread, but not from more
* than one at once. Does not need to be reentrant.
*
* @see avcodec_align_dimensions2()
*
* Audio:
*
* Decoders request a buffer of a particular size by setting
* AVFrame.nb_samples prior to calling get_buffer2(). The decoder may,
* however, utilize only part of the buffer by setting AVFrame.nb_samples
* to a smaller value in the output frame.
*
* As a convenience, av_samples_get_buffer_size() and
* av_samples_fill_arrays() in libavutil may be used by custom get_buffer2()
* functions to find the required data size and to fill data pointers and
* linesize. In AVFrame.linesize, only linesize[0] may be set for audio
* since all planes must be the same size.

/**
* Create and return a AVHWFramesContext with values adequate for hardware
* decoding. 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. The following error codes
* have special semantics:
* AVERROR(ENOENT): the decoder does not support this functionality. Setup
* is always manual, or it is a decoder which does not
* support setting AVCodecContext.hw_frames_ctx at all,
* or it is a software format.
* AVERROR(EINVAL): it is known that hardware decoding is not supported for
* this configuration, or the device_ref is not supported
* for the hwaccel referenced by hw_pix_fmt.
