[gst-devel] Convert mp4 to mpeg2 transport stream using qtdemux & mpegtsmux

[Raymond Tam]

That works! Thank you Ron and Edward (sorry Edward I missed the dot at the end).
Can you explain the meaning of the dot in the pipeline?

Thanks,
Raymond

Add a . to the end of the pipeline

gst-launch filesrc location=input_video.mp4 ! qtdemux name=demux demux.video_00 ! queue ! mpegtsmux name=mux ! filesink location=output_video.mpg demux.audio_00 ! queue ! mux.
