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.
