[jaymat at epix.net]

I just installed ffmpeg
ffmpeg version 2.7.6-0  ubuntu  0.15.10.1
I have an H265 mp4 file that I downloaded from a site. I can view this file using VLC on my MAC.
I want to stream this file, multicast encapsulated as a TS.The command line I am using is

  ffmpeg -re -i  uscenes_coral_garden_uhd_5-1_h-265_8bit.mp4 -c:v libx265 -vcodec copy -acodec copy -f mpegts udp://239.194.0.201:10002
Following output is displayed
