[FFmpeg-devel] [PATCH] avformat/mp3dec: set default disposition

[Gyan]

Fixes #8091, which reports what I consider a change rather than a 
regression since 11d3b03fcb2baae4324aac9481b9bd4a171d4345 
<http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=11d3b03fcb2baae4324aac9481b9bd4a171d4345>

It may be good practice to set default disposition in all demuxers which 
only accept one stream of a type.
