How to avoid sending RTCP Goodbye (203) packet type.

Postby vice » 12 Nov 2008 18:19

I've noticed a change of behavior between 0.8.6 and the 0.9 branch. As far as I know, 0,9 have introduce some support to sending RTCP packets as a server with the RTP stream module. I've tested 0.9.4 and 0.9.6 versions against a 0.8.6i, just to check my findings.

What I would like as a feature (don't know if its possible) is to disable the sending of RTCP Goodbye(203) packet type when I stop a VLM broadcast element or the input file being played reach the end. If this is not possible perhaps there's a way to avoid ANY RTCP packet.

Why I need this? Simply, because I'm trying to do a switch between different inputs files and a live stream using different VLM broadcast elements configured to stream by RTP (See viewtopic.php?f=11&t=47414 for more info). But if I stop and play another VLM broadcast element, the client stops because it receives a RTCP Goodbye packet. So the swtch effect is completely lost.

This could be a feature, if it's not possible. But what bother me more (and I think this could be a trac ticket) is the fact that if the VLM broadcast elements is in loop mode, each time the file reach the end, VLM sends a RTCP Goodbye packet closing the client and avoiding the client to see any "loop".


I tried to configure the VLM broadcast elements with sout-keep option with no effect. This could be a good option (feature): if sout-keep is ativated, don't send RTCP goodbye packets.

Thanks in advance.

Don't needed this anymore.
Changed architecture to playlist items switching and streaming adding gather module and sout-keep option.
This way, RTCP bye payload is not transmitted and as an extra bonus you get a more robust streaming (don't change source port for example).

Put here for reference and for other forum users information.
