  GStreamer | don't know | Ver: 0.10.13
           Summary: Conversion of MOV to OGG looses sync
           Product: GStreamer
           Version: 0.10.13
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: don't know
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: mcepl at redhat.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.25/2.26
   GNOME milestone: Unspecified


Please describe the problem:
Trying to convert
https://media.blackhat.com/bh-usa-09/video/KAMINSKY/BHUSA09-Kaminsky-BlackOpsPKI-VIDEO.mov
to OGG. When using ffmpeg I wasn't succesful
(https://bugzilla.redhat.com/show_bug.cgi?id=515435), so I tried my own script
using gst-launch and Gstreamer:

#!/bin/sh
QUEUE="queue max-size-bytes=0 max-size-time=0 max-size-buffers=0"
INFILE=$1

gst-launch filesrc location="$INFILE" ! \
    decodebin2 name=decoder \
    decoder. ! progressreport ! ffmpegcolorspace \
    ! theoraenc quality=40 speed-level=2 ! \
            $QUEUE ! oggmux name=mux \
        ! filesink location=${INFILE%.*}.ogv \
    decoder. ! audioconvert ! audiorate ! flacenc ! $QUEUE ! mux.

Conversion script goes well (resulting .ogv file has 359M), but it has totally
lost sync ... jump in totem once forward and there is absolutely no
correspondence between screen and audio.


Steps to reproduce:
1. see above
2. 
3. 


Actual results:
no way how to generate OGG/Theora file from the MOV presentation

Expected results:
just having the same experience from the free format movie as I have from the
encumbered one.

Does this happen every time?
yes

Other information:
totem playing .mov file works just fine, including jumping back and forth.
