* Handle AVID MJPEG streams directly in the MJPEG decoder.Anton Khirnov2021-02-25
| | | | | | | | | | | | | | | | | | | | AVID streams - currently handled by the AVRN decoder - can be (depending on extradata contents) either MJPEG or raw video. To decode the MJPEG variant, the AVRN decoder currently instantiates a MJPEG decoder internally and forwards decoded frames to the caller (possibly after cropping them). This is suboptimal, because the AVRN decoder does not forward all the features of the internal MJPEG decoder, such as direct rendering. Handling such forwarding in a full and generic manner would be quite hard, so it is simpler to just handle those streams in the MJPEG decoder directly. The AVRN decoder, which now handles only the raw streams, can now be marked as supporting direct rendering. This also removes the last remaining internal use of the obsolete decoding API.
* avformat/isom: Split movaudio/movvideo tags off into a separate fileAndreas Rheinhardt2021-02-23
The NUT and avi demuxers only need ff_codec_movvideo_tags and so this removes a dependency on the rest of isom.c as well as on mpeg4audio.c (which isom depends on); it is similar for the Matroska demuxer and muxers, except that the mpeg4audio.c dependency can't be avoided.
