           Summary: metadata is not preserved when converting from ogv to
                    ogv
           Product: Libav
           Version: 0.8
          Platform: X86
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: Normal
         Component: libavformat
        AssignedTo: bugzilla at libav.org
        ReportedBy: mihaim at gmail.com


Created attachment 386
  --> https://bugzilla.libav.org/attachment.cgi?id=386
console output of avprobe on the each involved files (original mov,
intermediate ogv, final ogv) and output of the two avconv commands

I had a batch of mov files which I converted to ogv. After completion, I wanted
to further ajust some of the resulting videos.

I noticed that upon conversion from ogv to ogv, the original metadata is not
kept. I mention that the metadata was preserved during the conversion from mov
to ogv. The only metadata of the final ogv file is
"ENCODER         : Lavf53.21.1"

Command lines used:
mov to ogv:
avconv -y -i dscn2961.mov -codec:v libtheora -b:v 1000k -codec:a libvorbis
dscn2961.ogv
ogv to ogv:
avconv -y -i dscn2961.ogv -codec copy dscn2961_.ogv
