[Live-devel] RTSP client doesn't receive stream if SDP attribute is "recvonly"

Our RTSP client code (which, by the way, supports only RTSP version 1.0; not RTSP version 2.0) completely ignores the “a=recvonly” attribute.  (In fact, this attribute is not even defined fully in the RTSP 1.0 specification; it just happens to be used in a couple of examples.)

Therefore, there must be some other reason why we are not receiving your RTSP/RTP/RTCP stream.  Do you have a publicly-accessible “rtsp://“ URL that we can test?
