But still a separate profile-level-id ftmp line per level should be acceptable (as worst-case scenario), right?
Yuval,
The level is the highest level supported so level 3 means that you also support level 1. This is specified in RFC 3984.
B can offer level 3.

offer/answer Question
Hi,
I would like to clarify the following scenario:
A and B use the same H.264 profile and packetization mode (this assumption is only for simplicity).
A supports up to level 3.0, and B supports only level 1.0.
A doesn't know the level supported by B, and it wants to start the negotiation as offerer.
My understanding is that A needs to send in the SDP new
attribute for each level from 1.0 to
Regards,
Yuval
