[gst-devel] Question on x264enc + mp4mux

[Chen, Weian]

Hi All

I have a problem when doing encode + mux:

Encode pipeline is as following:  gst-launch videotestsrc ! x264enc ! mp4mux ! filesink location=test.mp4, and then I use crtl + c to destroy the pipeline, then using   gst-launch filesrc location=1.mp4 ! qtdemux ! ffdec_h264 ! xvimagesink to decoder, but the pipeline is hang up with log:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...


But if I use gst-launch videotestsrc num-buffers=30 ! x264enc ! mp4mux ! filesink location=test.mp4, and do not use ctrl + c to destroy, the decoder pipeline can work well.

Could anyone here help to explain this strange phenomenon to me?

Thanks in advanced.

thanks,
Weian
