Could not link ffdemux_mpegts0 to videoqueue

[gagankumarnigam]

Hi Tim,

I also added video pad with demuxer Still same issue could not link
mpegtsdemux0 with queue. 
Also replied in previous post if remove mpegtsdemux then code runs and
compile nicely with display nothing.
see my code given below i added pad .
