Yes. The RTP payload format for JPEG streaming (RFC 2435) requires that the width and height of the image be a multiple of 8 pixels. (The payload format is not defined for widths or heights that are not multiples of 8 pixels.) So, if you insist on streaming via motion-JPEG (but see <http://live555.com/liveMedia/faq.html#jpeg-streaming> for why this is usually a bad idea), your image widths/heights must be a multiple of 8.
