[jitsi-dev] msid-semantic missing from first offer in Jitsi Meet


#1

The "a=msid-semantic: WMS mixedmslabel" is missing from the first SDP OFFER in Jitsi Meet, even though the ssrc block shows the msid:

a=ssrc:1114107067 cname:mixed
a=ssrc:1114107067 label:mixedlabelaudio0
a=ssrc:1114107067 msid:mixedmslabel mixedlabelaudio0
a=ssrc:1114107067 mslabel:mixedmslabel

Is there a specific reason for that or is it by accident and luckily working anyhow?

As I read here, the "a=wms-semantic" attribute has been removed:

https://tools.ietf.org/html/draft-ietf-mmusic-msid-15

So I guess we don't need it anymore.

Haven't checked if there is a replacement. I saw something like "a=msid", but it seems to work when it's in "a=ssrc".
