[jitsi-dev] macOS Firefox doesn't show H264


I created issues at

It's likely because there is no


in the SDP, so Firefox doesn't know what profile to choose and ignores.

Currently, the issue is to be fixed in Jicofo since it returns SDP in
non-p2p mode. Also, I believe it can be worked around in lib-jitsi-meet,
but it's less reliable.

I just tried apprtc with firefox 56 and 57 and it looks like maybe
something broke/changed in 57. I can't get firefox 57 to do h264 with
chrome on apprtc, but 56 was working. I tried messing with a couple of the
config settings, but that didn't seem to help. Seems like it might be
worth asking on the discuss-webrtc list.
