           Summary: avidemux: a/v sync off on sample video when activated
                    in push mode
    Classification: Platform
           Product: GStreamer
           Version: 1.x
        OS/Version: Linux
            Status: UNCONFIRMED

          Priority: Normal
         Component: gst-plugins-good

The following pipeline has avsync off by 500ms, on 1.0.5 or git master:

gst-launch playbin uri=http://absolut.zogzog.org/share/samples/avi/s7e3.avi

This is because avidemux outputs invalid timestamps for audio in push mode.
