            Bug ID: 751298
           Summary: flvmux: produced files does not work well with common
                    flash players
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: major
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org

Created attachment 305785
  --> https://bugzilla.gnome.org/attachment.cgi?id=305785&action=edit
file generated with the given pipeline

Please try this pipeline:

gst-launch-1.0 videotestsrc pattern=18 num-buffers=1000 ! openh264enc !
h264parse ! flvmux ! filesink location=/tmp/test.flv

now try to play the generated file with a flash player, for example flowplayer:

- the file does not start, you have to seek forward some seconds to start to
play
- at random interval the player freeze (same as at the start) and you have to
seek to restart play, in the example file you'll see the freeze at about 25
seconds

now use ffmpeg to reconvert the flv generated by gstreamer with something like
this:

ffmpeg -i /tmp/test.flv -vcodec copy  -f flv /tmp/test_ffmpeg.flv

the file generated by ffmpeg start and play perfectly in flowplayer.

I observed random freeze while playing gst generated flv since several time
(even with 0.10). Recent gst version added the initial freeze that I don't
remember in previous versions.
