That's correct. If you're streaming H.264, then this information (height & width) is included in the "sprop-parameter-string" (formed by the stream's SPS and PPS NAL units), so receiving media players should not need it to be specified separately. The same is true for most (but perhaps not all) other video codecs. However, if you are trying to save an incoming stream into a ".mov" (or ".mp4") or ".avi" file, then the height and width parameters (and also frame-rate) can help.
