OK I upgraded a server today from 63057 to 78734 as we had a problem with dvbsubtitles not working. 

Now the machines, 2 of them one on 63057 and the new one, dont transcode and they have the same command lines like this.
ffmpeg -i http://1.1.1.1:11111/Stream1.ts -c:v copy -c:a copy -f mpegts udp://225.1.1.1:11111?pkt_size=1316
These pull in streams from a remote server and push the data into a professional playout server, Edgeware WTV-2X
Now the streams pulled and sent out to the Edgeware with software 63067 are OK, the streams sent out from 78734 are not accepted and made available by the Edgeware.
Anyone have any ideas or seen this behaviour in later versions as the transcoder is remote and has NOT been updated.

I was going to bisect it and see if i can find a commit which breaks the mpegts output?, but what commit do I start on for 63057
