/**
* Identify the syntax and semantics of the bitstream.
* The principle is roughly:
* Two decoders with the same ID can decode the same streams.
* Two encoders with the same ID can encode compatible streams.
* There may be slight deviations from the principle due to implementation
* details.
*
* If you add a codec ID to this list, add it so that
* 1. no value of a existing codec ID changes (that would break ABI),
* 2. Give it a value which when taken as ASCII is recognized uniquely by a human as this specific codec.
* This ensures that 2 forks can independently add AVCodecIDs without producing conflicts.
*
* After adding new codec IDs, do not forget to add an entry to the codec
* descriptor list and bump libavcodec minor version.

* Decode the audio frame of size avpkt->size from avpkt->data into frame.

* less than the packet size. In this case, avcodec_decode_audio4 has to be
* called again with an AVPacket containing the remaining data in order to
* decode the second frame, etc... Even if no frames are returned, the packet
* needs to be fed to the decoder with remaining data until it is completely
* consumed or an error occurs.
*
* Some decoders (those marked with CODEC_CAP_DELAY) have a delay between input
* and output. This means that for some packets they will not immediately
* produce decoded output and need to be flushed at the end of decoding to get
* all the decoded data. Flushing is done by calling this function with packets
* with avpkt->data set to NULL and avpkt->size set to 0 until it stops
* returning samples. It is safe to flush even those decoders that are not
* marked with CODEC_CAP_DELAY, then no samples will be returned.
*
* @warning The input buffer, avpkt->data must be FF_INPUT_BUFFER_PADDING_SIZE
* larger than the actual read bytes because some optimized bitstream
* readers read 32 or 64 bits at once and could read over the end.
*
* @param avctx the codec context
* @param[out] frame The AVFrame in which to store decoded audio samples.
* The decoder will allocate a buffer for the decoded frame by
* calling the AVCodecContext.get_buffer2() callback.
* When AVCodecContext.refcounted_frames is set to 1, the frame is
* reference counted and the returned reference belongs to the
* caller. The caller must release the frame using av_frame_unref()
* when the frame is no longer needed. The caller may safely write
* to the frame if av_frame_is_writable() returns 1.
* When AVCodecContext.refcounted_frames is set to 0, the returned
* reference belongs to the decoder and is valid only until the
* next call to this function or until closing or flushing the
* decoder. The caller may not write to it.
* @param[out] got_frame_ptr Zero if no frame could be decoded, otherwise it is
* non-zero. Note that this field being set to zero
* does not mean that an error has occurred. For
* decoders with CODEC_CAP_DELAY set, no given decode
* call is guaranteed to produce a frame.
* @param[in] avpkt The input AVPacket containing the input buffer.
* At least avpkt->data and avpkt->size should be set. Some

* output stream the packet is sent to.
* @param args arguments which specify the filter configuration, may be NULL
* @param poutbuf pointer which is updated to point to the filtered buffer
* @param poutbuf_size pointer which is updated to the filtered buffer size in bytes
* @param buf buffer containing the data to filter
* @param buf_size size in bytes of buf
* @param keyframe set to non-zero if the buffer to filter corresponds to a key-frame packet data
* @return >= 0 in case of success, or a negative error code in case of failure
*
* If the return value is positive, an output buffer is allocated and
* is available in *poutbuf, and is distinct from the input buffer.
*
* If the return value is 0, the output buffer is not allocated and
* should be considered identical to the input buffer, or in case
* *poutbuf was set it points to the input buffer (not necessarily to
