AES67/Dante/Ravenna usually also contain information about packet sizes
and most importantly clock synchronization (according to RFC7273) in
the SDP. Check the relevant specs :)

I don't think VLC supports any of that.

Also you probably mean L24 there instead of L2.


How is this related to GStreamer though?
