This appears to come straight from ffmpeg, but here's the thing: VLC opens it just fine. I'm not doing anything special in VLC, just running "vlc rtsp://cam-front-gate:5554" works, which is the same string I give to zoneminder.

Re: zmc: Unable to open RTSP input, invalid data found when processing input

Post by vitus » Thu Sep 12, 2019 3:36 am

After enabling FFMPEG logging, I discovered the source of the issue was that the generic Android RTSP server didn't support TCP as a transport option, but (annoyingly) it did continue to negotiate anyway but just sent a response with UDP in the response header :twisted:
