My issue is audio stuttering. Since I can find no QOS relating I tried rt priority:

dvr at dvrTW:~> sudo chrt -f 5 ./dvrRecord http://192.168.5.116 1 /dev/video2 0 0x03800006 0x03600006 nother.mp4

[error] Unable to set the pipeline to the playing state.

So I check without rt

dvr at dvrTW:~> ./dvrRecord http://192.168.5.116 1 /dev/video2 0 0x03800006 0x03600006 nother.mp4

And it works just fine. 
Why would launching a pipelne with rt prior stop it from running?
