b55c6b8c40 avformat/avformat: Update AVInputFormat.read_packet documentation 
Since bae8844e35, the packet is automatically unreferenced in
ff_read_packet() when an error is returned; but the documentation of
this of AVInputFormat.read_packet has not been updated accordingly.

56a04b7c38 avformat/segafilmenc: Check early whether video is allowed 
The current code only checks when writing the trailer whether the video
format and Codec ID are actually compatible with the container. At this
point, a lot of data will already have been written (in vain, of
course), so check during the init function instead.

30859c270f avformat/segafilmenc: Postpone check for existence of video stream 
Up until now, the Sega FILM muxer complained if the first stream wasn't a
video stream that there is no video stream at all which is of course
nonsense. So postpone this check.

it's stranage to use option "level" in runtime change path but used
"quality" in option, add "quality" in runtime change path, it's more

6a1bf8634a avformat/matroskaenc: Fix ReferenceBlock timestamp 
In order to indicate that the frames in a BlockGroup are not keyframes,
one has to add a ReferenceBlock element containing the timestamp of a
referenced Block that has already been written. The timestamp ought to be
relative to the timestamp of the Block it is attached to. Yet the
Matroska muxer used the relative timestamp of the preceding Block of the
track, i.e. the timestamp of the preceding block relative to the
timestamp of the Cluster containing said block (that need not be the
Cluster containing the current Block). This has been fixed.
