- * Decodes a video frame from \p buf into \p picture.
- * The avcodec_decode_video() function decodes a video frame from the input
- * buffer \p buf of size \p buf_size. To decode it, it makes use of the
- * video codec which was coupled with \p avctx using avcodec_open(). The
- * resulting decoded frame is stored in \p picture.
- *
- * @warning The input buffer must be \c 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 \p buf should be set to 0 to ensure that
- * no overreading happens for damaged MPEG streams.
- *
- * @note You might have to align the input buffer \p buf and output buffer \p
- * 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, the
- * bitstream should have 4 byte alignment at minimum and all sample data should
- * be 16 byte aligned unless the CPU doesn't need it (AltiVec and SSE do). If
- * the linesize is not a multiple of 16 then there's no sense in aligning the
- * start of the buffer to 16.
- *
- * @param avctx the codec context
- * @param[out] picture The AVFrame in which the decoded video frame will be stored.
- * @param[in] buf the input buffer
- * @param[in] buf_size the size of the input buffer in bytes
- * @param[in,out] got_picture_ptr Zero if no frame could be decompressed, otherwise, it is nonzero.
- * @return On error a negative value is returned, otherwise the number of bytes
- * used or zero if no frame could be decompressed.

- * Pixel format. Notes:
- *
- * PIX_FMT_RGB32 is handled in an endian-specific manner. A RGBA
- * color is put together as:
- * (A << 24) | (R << 16) | (G << 8) | B
- * This is stored as BGRA on little endian CPU architectures and ARGB on
- * big endian CPUs.
- *
- * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
- * image data is stored in AVFrame.data[0]. The palette is transported in
- * AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is
- * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
- * also endian-specific). Note also that the individual RGB palette
- * components stored in AVFrame.data[1] should be in the range 0..255.
- * This is important as many custom PAL8 video codecs that were designed
- * to run on the IBM VGA graphics adapter use 6-bit palette components.
