Hi, I'm a little bit new on these subjects, so sorry for this. I reworded my question below. Thanks in advance.
We're multicast streaming video from an IP camera over RTP. But when we do this, we start streaming without having any RTSP PLAY command. And I guess our switches have layer2 support, so they send data to everyone. Apparently this makes our network very busy. Is there any way not to stream multicast without having a RTSP PLAY command? And also we want to cut multicast streaming when there is no listener for the stream. Is this possible? Or is it completely wrong thinking for a multicast stream?

Consequently, your question was rather unclear. Please note the distinction between RTSP, and RTP/RTCP. Then please reword and resubmit your question.

I'm relaying an authenticated rtsp stream from a webcam. I'm using proxyserver as follows: live555ProxyServer -p 554 -R -U user pass 'rtsp://user:pass@cameraip/videostream' Whenever I open the proxied video stream for the first time in a while, I get the following from the client (ffplay, vlc, or anything else): Playing: rtsp://server/proxyStream [ffmpeg/demuxer] rtsp: method PLAY failed: 454 Session Not Found If I reopen the video stream immediately after that, it works. As long as I keep open a video stream somewhere, the stream starts without issues. I did some tests in the past: - If I open the webcam stream directly, it always works, so even though we're speaking about a cheapo no-brand usb webcam, I didn't have issues when opening the stream directly from it. - I cannot disable authentication on the webcam stream to test if authentication is creating issues. - I can (and tried) disabling authentication in proxyserver, but it made no difference. ------------------------------ Message: 4 Date: Mon, 16 Sep 2019 10:59:03 -0700 From: Ross Finlayson <[email protected]> To: LIVE555 Streaming Media - development & use <[email protected]> Subject: Re: [Live-devel] rtsp proxy error on first request Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8 > On Sep 16, 2019, at 6:21 AM, Yuri D'Elia <[email protected]> wrote: > > I've been using live555ProxyServer for a while, starting a couple of > years ago and currently using 2019.08.28 from debian unstable. > > I'm relaying an authenticated rtsp stream from a webcam. > I'm using proxyserver as follows: > > live555ProxyServer -p 554 -R -U user pass > 'rtsp://user:pass@cameraip/videostream? Try instead: live555ProxyServer -p 554 -u user pass 'rtsp://cameraip/videostream? I.e., use "-u <username> <password>? (*not* -U), and don?t include the username:password in the RTSP URL. > Whenever I open the proxied video stream for the first time in a > while, I get the following from the client (ffplay, vlc, or anything else): > > Playing: rtsp://server/proxyStream [ffmpeg/demuxer] rtsp: method PLAY > failed: 454 Session Not Found Try adding the -V (upper-case V) option, to get verbose diagnostic output, and send us this diagnostic output, when the problem occurs.
