FS-4382 reverse this so you have to enable instead of disable, this patch has been causing srtp issues because the change in ssrc

cc1: warnings being treated as errors

FS-4435 looks ok at a glance, at least this code is isolated to the small few who actually use it so i will put it in for testing

FS-4317 this might help, this fixes a regression cause by another recently altered code path and it sounds similar but I never got the new logs from you so this is a guess

FS-4429 --resolve you guys should come to cluecon we would like to help you get bvtapi working really well

FS-4427 try this revision however i think its a problem with the remote client not properly preserving the headers of the srtp packets.....
