What software is the server and which GStreamer version are you using? Can you get a wireshark dump of the communication between GStreamer and the server and create an issue in gitlab with that? I have some guesses what the problem here is. -- Sebastian Dröge, Centricular Ltd · https://www.centricular.com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

I would recommend updating, even if this won't solve your specific problem here it would at least solve lots of others.

I only looked shortly now but this looks like yet another server that sends broken data. What happens here if I see it correctly is that after packet 195 the packets that are sent by the server are broken. After the interleaved RTP packet sent in packet 195 there's some garbage, and that garbage continues from there on. I assume somewhere in the garbage there are still some interleaved RTP packets but it's not allowed in RTSP to send random garbage between valid RTSP messages. I believe ffmpeg/VLC have some resyncing code for this, we currently don't do that (because it's simply a broken server!) but it would probably make sense to add some code for trying to recover from such situations. As you can see, wireshark also starts failing to parse all packets after 195, which happens for the same reason. My guess is that this is another live555-based RTSP server. I saw this kind of bug with many of them in the past, and so far none of the camera/etc vendors I'm aware of bothered to fix it on their side because "it works in VLC". -- Sebastian Dröge, Centricular Ltd · https://www.centricular.com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
