A camera should not depend upon its server including an "a=x-dimensions..." 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). 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. (Be warned, however, that requests like this by hobbyists are considered low priority.)
