Comment:
I apparently misunderstood the issue originally: ffplay automatically
chooses streams 0:8 and 0:6 for playback which works fine (this
corresponds to mplayer -demuxer lavf -vid 3 -aid 1), ffmpeg tries to
transcode video stream 0:3 which fails (like mplayer -demuxer lavf -vid
0), workaround is the following command line:
$ ffmpeg -i ffmpeg_not_terminating.rm -map 0:8 -map 0:6 -r 30 out.mpg
There is definitely a problem with the demuxer that can be shown with the
sample, the following mplayer command lines show videos with different
fps:
$ mplayer ffmpeg_not_terminating.rm -demuxer real -nosound -vc ffrv20 -vid
1
$ mplayer ffmpeg_not_terminating.rm -demuxer real -nosound -vc ffrv20 -vid
4
$ mplayer ffmpeg_not_terminating.rm -demuxer real -nosound -vc ffrv20 -vid
