I am trying to retrieve a YoutubeLive stream and send the video stream 
to a video loopback device and the audio to my souncard. This works 
however it appears that the audio is delayed by a second or so. Is there 
a better way to do this so they aren't out of sync or failing that is 
there a way to set a delay on the video stream to compensate? Below is 
my command. I am using the Sky News You Tube Live as a test signal. I am 
on Ubuntu 19.10 .

ffmpeg -re -i $(youtube-dl -g -f 96
