<p class="x_MsoNormal">Thank you for the answer! I’ve noticed this behaviour in the newest VLC version and they told me that I should inform Live555. The RTSP server is integrated in an AoIP (Audio over IP) device and it is not available at the moment. I’m
able to modify the RTSP/SDP part. If I’m using “a=sendonly” instead of “a=recvonly” it works without any issue, nothingelse has changed only "a=sendonly”. I’m using in both case a multicast address.</p>

<div class="PlainText">> If RTSP servers are using the correct SDP option "recvonly" as defined in<br>

<br>
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.)<br>
<br>
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?<br>
