Shorter GOP would therefore mean a higher bitrate due to the increased 
number of I-frames. So that may cause more issues with APs that can't 
handle multicast properly?!?

Else, I agree with your statement in your previous message, I would like 
to see Raptor FEC supported in VLC. That combined with the work in the 
IETG RMT WG may allow us to solve the issue some time in the future.
