           Summary: memory leak + sound distortion issues since 1ab5a
           Product: Libav
           Version: 9
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: libavcodec
        AssignedTo: bugzilla at libav.org
        ReportedBy: slawomir.nizio at sabayon.org


Since this commit (lvavc: add Ut Video encoder), melt from MLT produces
"broken" video sometimes: it allocates more and more memory, and the sound is a
little too fast (video seems to be okay).

I'm filing the bug report here and not in MLT for the reasons below. Feel free
to tell me do otherwise; I cannot be certain it's a bug in libav but I think it
may be.

1. Before this commit, melt produces correct output.
2. The ffmpeg project had something that looked somewhat similar.
https://trac.ffmpeg.org/ticket/2661
The change from the commit they claim fixes the issue is not present in libav.
But then, they claim it's a regression from ffmpeg's fb3e380, and the change
introduced by this commit is not present in libav either.

On the other hand, I didn't reproduce it with pure avconv. :(
Please take a look anyway.

It can be reproduced this way, using libav from 1ab5a.
mod.mlt: {{{
<mlt>
 <producer>
  <property name="resource">test.flv</property>
 </producer>
</mlt>
}}}

command: melt mod.mlt -consumer avformat:a.mp4

I reproduced it with (at least) mlt 0.9.0 and libav 9.10 and 9.x git.
