Thanks for your reply. I am replying on behalf of Pawan
The output of gst-launch is as below.
balakrishnan at bglldtw126:~/Bala/Work$ gst-launch-0.10 filesrc
location=test_h264_aac.avi ! avidemux name=demux { qtmux name=mux ! filesink
location=output.mp4 } { demux. ! queue ! audiopass ! mux. } { demux. !
queue ! videopass ! mux. }
(gst-launch-0.10:18379): GLib-GObject-WARNING **: cannot register existing
type `GstSignalProcessor'
(gst-launch-0.10:18379): GLib-CRITICAL **: g_once_init_leave: assertion
`initialization_value != 0' failed

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Setting CapsSetting CapsPipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
So the pipeline goes into playing mode and is stuck in there.
So at this instant the output.mp4 is 0 bytes in size
However when i forcefully (ctrl C) terminate the pipeline
the output.mp4 ( find attached with the mail) is 317 bytes in size which is
of course not playable.
I have attached the logs with the following option
GST_DEBUG=qtmux:5,filesink:5,queue:5
Looking att that i feel the pipeline is somewhere stuck in the queue.
the avidmux continuously runs with out any problems so have not taken the
same.
I have also attached the sources for audiopass and the videopass elements
mentioned below.
Please see the same and do let me know your observations
Thanks
