Using this command (note I am using a slightly modified version of out_route.c to support updated and/or new ATSC 3.0 related features, built on the latest pull from github. Also note, I had the same issue with the non-modified out_route.c):

`gpac -i videos/world.mp4 reframer:rt=on dasher:profile=live:#ATSC3ShortServiceName=K16XX-D:#ATSC3MajorChannel=16:#ATSC3MinorChannel=1:#ATSC3ServiceCat=1:#ROUTEUpload=0.5:#ROUTECarousel=2 -o atsc://:ip=239.6.15.16:first_port=30000:bsid=1:llmode`

gpac is creating the ATSC3 LLS stream on 224.0.23.60 port 4937, as per the standard.  However, it is not streaming the mp4 file. I can see port 30000 open in netstat as well as multicast group 239.6.15.16 active in netstat.  tcpdump port 30000 shows no packets.  tcpdump port 4937 shows packets and further analysis shows the LLS packets to be correct.  

Only errors from gpac are:
`[Dasher] First CTS 5392800 in segment 60 drifting by 0.92 (more than half a segment duration) from segment time, consider reencoding or using segment timeline`
and
`[Dasher] Segment 67 duration 0.48 less than half DASH duration, consider reencoding or using segment timeline`

Would those errors cause DASH/ROUTE to not stream the mp4?  Any other ideas on what might be the problem?

Thanks!
