SDP line, because this attribute is optional (and not even a standard). All decoders should be able to infer the video width and height from the encoded input stream, or from other "a=fmtp:..." configuration parameters (which *are* standards).</div><div><br></div><div>However, in the spirit of "be liberal in what you accept", I agree that the "LIVE555 Proxy Server" should pass on this attribute if it sees it. So, a fix for this will be included in a future release of the software.
