<div dir="ltr">Hi Ross,<div><br></div><div>I tried with openRTSP client and able to connect in the mentioned scenarios but what I observed is that the response for DESCRIBE from RTSP server comes with a lot of delay; in such scenario openRTSP waits for the response whereas other rtsp clients like vlc/ffplay do not wait and terminate. Can we do something at the RTSP server side to handle this scenario as in general scenario people use vlc as preferred rtsp client.</div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><br></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Dec 22, 2022 at 2:19 PM Ross Finlayson <<a href="mailto:finlayson@live555.com">finlayson@live555.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>

Rather than using VLC (which is not our software, even though it uses our software as its RTSP client), I suggest using our command-line RTSP client “openRTSP”, which is included in the LIVE555 software (in the “testProgs” directory. See:<br>
<a href="http://live555.com/openRTSP/" rel="noreferrer" target="_blank">http://live555.com/openRTSP/</a><br>
<br>
Just run:<br>
openRTSP rtsp://<a href="http://192.168.1.157:554/main_stream" rel="noreferrer" target="_blank">192.168.1.157:554/main_stream</a><br>
and see what happens.<br>
