Nice. Whats the downsize of doing it this way? It seems like out of the box, motion does not support h.264 codec.

tosiara · 2024-01-03T07:22:26Z

Packaged Motion uses ffmpeg libs to decode H264 and it comes out of the box. It's only a problem with some non-compliant cameras that require a custom ffmpeg build with a workaround to force TCP

nopenopenope · 2024-01-03T10:13:39Z

After writing the comment, I figured that mkv for example is h264 encoded, so that worked. Sorry for the irrelevant weight to the issue.

Mr-Dave · 2024-01-10T04:46:24Z

Can you explain this issue more? Generally, we don't want UDP we want rtsp_transport tcp and this can be specified via the Motion option of netcam_params. (It is actually already the default). I didn't think that any such patch to ffmpeg was required. Simply specify it as the option instead of UDP.

For general issues with the camera not being detected or failing to analyze, the solution is usually to lower the camera GOP/I-Frame interval.

tosiara · 2024-01-10T14:19:26Z

The issue here is that ffmpeg out of the box tries to follow RTSP protocol. The camera in turn, supports TCP, but does not advertise it correctly, and motion fails to connect since motion forces TCP by default (perfectly explained by @eusoubrasileiro at https://stackoverflow.com/questions/66280861/ffmpeg-nonmatching-transport-in-server-reply-but-openrtsp-works)

There are two workarounds here.

Configure motion to use UDP
Or, patch ffmpeg to force use TCP even though the camera does follow RTSP protocol standards

Mr-Dave · 2024-01-10T17:14:48Z

I'm still not following the issue/problem for Motion to resolve. Is this just a FYI/"How to" for those that have one of these cameras?

tosiara · 2024-01-10T18:48:59Z

Yes, this was more like FYI for everyone as there were many users affected
