Hi Ravindra,
please reply to the list, I no longer work on gstreamer so I can't help
much.
Stop using gst-launch, it should burn in hell. Specifically, quitting your
pipeline won't generate a proper EOS when using gst-launch. This will cause
no proper 3gp header to be appended to the data (in the ffmpeg mov/3gp/etc
muxer, the header comes after the data). The result is that the file has no
valid header and is thus unplayable. The solution is to generate an EOS in
the pipeline so the pipeline can shut down, header will be appended and the
3gp file is methodically valid and playable.
I don't know how to do that in the current gst API, I hope the gst devs (CC:
gst-devel) can help you with that.
