[Bug 1386218] [NEW] avconv from libav-tools.deb generate bad video in trusty/utopic but only "happened in i386 not amd64"
You have been subscribed to a public bug:
I have a series of x86 machines for converting multimedia, but an bug
from avconv(from libav-tools.deb) annoyed me for a long time (and it
even happen in 14.10) that mixing video and audio using avconv generated
a bad media output - output video is continuity continuously suspended,
which cannot be used (output audio is okay).
Finnally, I find out that it only happens in 32bit 14.04 and 14.10, but
it's hard to replace i386 to amd64.
A command to reproduce the bug:
> avconv -f x11grab -i :0.0 -f alsa -i pulse -f flv -ar 22050 test.flv
Ubuntu 12.04.5 i386:good, amd64:good
Ubuntu 13.10 i386:good, amd64:good
Ubuntu 14.04.1 i386:bad, amd64:good
Ubuntu 14.10 i386:bad, amd64:good
'bad' warning forever:
Non-monotonous DTS in output stream 0:1; previous: 3947,
current: 3891; changing to 3947. This may result in incorrect timestamps
in the output file.
Need help, thanks!
