Comment (by dgillier):
Command line use with testsrc :
ffmpeg -f lavfi -i testsrc -f s16le -i /dev/zero -s 640x360 -vcodec mpeg4
-g 60 -vb 400000 -strict -2 -acodec aac -f segment -segment_time 1800 -map
0 -map 1 /mnt/video/tests/test-mp4-%03dt.mp4
Command line used in production:
ffmpeg -i $MPEGTS_URL_UDP -map 0:0 -map 0:1 -s 640x360 -vcodec libx264 -g
60 -vb 500000 -strict experimental -vf yadif -acodec aac -ab 96000 -ac 2
-y -f segment -segment_format mp4 -segment_time 1800
/mnt/video/$STATION-%03dt.mp4
Duration is correct from testsrc, but with the one I use I cannot read the
segmented file, I added the second pass :
ffmpeg -i test-mp4-979t.mp4 -c copy test-979.mp4.
And after this one duration file are incorrect.
With testsrc it is the same on all files. With UDP source it happens only
after the 024.
