           Summary: flv: Container timestamp is DTS not PTS
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED

          Priority: Normal

     GNOME version: ---


The flv container contains DTS, not PTS. The PTS is obtain through the
composition time (CTS):

PTS = DTS + CTS

Our implementation do the opposite, hence there is bugs when DTS != PTS. For
the demuxing, it result in a lot of warning, and for muxing it produce streams
that are very choppy on adobe flash and vlc. I have working patches to fix the
video tag, will need to finish before publishing.
