- * Wrapper function which calls avcodec_decode_audio4.
- *
- * @deprecated Use avcodec_decode_audio4 instead.
- *
- * Decode the audio frame of size avpkt->size from avpkt->data into samples.
- * Some decoders may support multiple frames in a single AVPacket, such
- * decoders would then just decode the first frame. In this case,
- * avcodec_decode_audio3 has to be called again with an AVPacket that contains
- * the remaining data in order to decode the second frame etc.
- * If no frame
- * could be outputted, frame_size_ptr is zero. Otherwise, it is the
- * decompressed frame size in bytes.
- *
- * @warning You must set frame_size_ptr to the allocated size of the
- * output buffer before calling avcodec_decode_audio3().
- *
- * @warning The input buffer 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.
- *
- * @warning The end of the input buffer avpkt->data should be set to 0 to ensure that
- * no overreading happens for damaged MPEG streams.
- *
- * @warning You must not provide a custom get_buffer() when using
- * avcodec_decode_audio3().  Doing so will override it with
- * avcodec_default_get_buffer.  Use avcodec_decode_audio4() instead,
- * which does allow the application to provide a custom get_buffer().
- *
- * @note You might have to align the input buffer avpkt->data and output buffer
- * samples. The alignment requirements depend on the CPU: On some CPUs it isn't
- * necessary at all, on others it won't work at all if not aligned and on others
- * it will work but it will have an impact on performance.
- *
- * In practice, avpkt->data should have 4 byte alignment at minimum and
- * samples should be 16 byte aligned unless the CPU doesn't need it
- * (AltiVec and SSE do).
- *
- * @note Codecs which have the CODEC_CAP_DELAY capability set have a delay
- * between input and output, these need to be fed with avpkt->data=NULL,
- * avpkt->size=0 at the end to return the remaining frames.
- *
- * @param avctx the codec context
- * @param[out] samples the output buffer, sample type in avctx->sample_fmt
- *                     If the sample format is planar, each channel plane will
- *                     be the same size, with no padding between channels.
- * @param[in,out] frame_size_ptr the output buffer size in bytes
- * @param[in] avpkt The input AVPacket containing the input buffer.
- *            You can create such packet with av_init_packet() and by then setting
- *            data and size, some decoders might in addition need other fields.
- *            All decoders are designed to use the least fields possible though.
- * @return On error a negative value is returned, otherwise the number of bytes
- * used or zero if no frame data was decompressed (used) from the input AVPacket.
