I'm trying to use/view some assorted videos made by someone else.
Basically, just want to play them with VLC.
However *some* of the files don't work as they should. If I start from
their beginning and let them play though, all seems fine. But if I try to
jump to a different place (time) I get the sound going AWOL.
Using VLC's option to select (or not) a soundtrack to disable sound and
then re-enable it *sometimes* it then gives sound - but not for the same
part of the file as the video being shown!
ffmpeg / ffmprobe shows what I'd expect. In essence, 'timestamps' not set
in stream 0 (the video).
Simple question. How do I use ffmpeg to make a copy that leaves the video
and audio data unchanged but adds the needed set of timestamps to the
stream?
Files as give have an .avi exension. ffmpeg seems to accept doing -acodec
and -vcodec copies to some alternatives containers, but that changes nowt
owt about the above, of course).
I did a websearch and just got stuff on adding a visible clock to the
video, not on fixing this PITA.
Thanks,
Jim
