Hello Youenn,

We are currently already doing what you suggest. If you examine the offer and answer images we have attached you will see that each side supports H.264 base profile and neither supports H.264 high profile. What we have observed is that even with this SDP exchange we are receiving an H.264 RTP stream that contains a profile-level-id set to high profile in the H.264 header and features only available in high profile are present in the video stream. This should not be allowed based on the SDP exchange. Can you please examine this issue from this perspective and let us know if you need anything from us to expedite this? This was tested on a brand new and fully updated Mac Book Pro running Mojave and the latest version of Safari.
