When is the remote video resolution/size known?

Hi all,

Once a PC gets connected to the remote peer I add a video element to show
the remote video. At that point I do not know the remote video resolution
(as that is known upon receipt of the RTP).

In which moment can I know the video resolution/size? Any event fired
within the remote MediaStream or MediaStreamTrack?

Thanks a lot.
