            Bug ID: 751874
           Summary: uvch264mjpgdemux: Output h.264 stream doesn't have pts
                    information (GST_CLOCK_TIME_NONE)
    Classification: Platform
           Product: GStreamer
           Version: 1.5.2
                OS: Linux
            Status: NEW
          Severity: major
          Priority: Normal
         Component: gst-plugins-bad

     GNOME version: ---

I am using uvch264src plugin for obtaining Preview (jpeg at 360p) and main stream
(h.264 at 1080p) at 15 fps.
Camera: Logitech c920.

Internally uvch264src uses uvch264mjpgdemux for doing the demux operation.
After demuxing step, the pts of the h.264 stream is set to GST_CLOCK_TIME_NONE
(99:99:99.999999999). Even if I pass this through h264parse, the pts of the
stream is not fixed. As a result, when I dump this video muxed with audio onto
file system (.mp4), the video frame is frozen, while the audio playbacks
normally (using VLC player). Playback doesn't work at all using gst-play-1.0
