v4l2rtspserver Discarding frame [SOLVED]

[thorus]

Hi,

I have an raspberry pi with an Noir V2.1 attached, and want to integrate it into zoneminder. So I compiled v4l2rtspserver(https://github.com/mpromonet/v4l2rtspserver) to stream the captured video stream via rtsp to zoneminder.

I started the v4l2rtspserver via "v4l2rtspserver -F 30" and configured the webcam in zoneminder as follows:

Server: None
Source Type: Remote
Function: Monitor


Remote Protocol: RTSP
Remote Method RTP/Unicast
Remote Host Name: 192.168.99.230 (The IP of the rpi)
Remote Host Port: 8554
Remote Host Path: /unicast
Target colorspace: 32bit


I can play the stream with mpv just fine: mpv rtsp://192.168.99.230:8554/unicast

But with zoneminder I get no picture, and in the logs its periodically written:

Dec 29 16:12:47 zoneminder zmc[18281]: WAR [Discarding frame 691]
Dec 29 16:12:47 zoneminder zmc[18281]: WAR [Discarding incomplete frame 691, 0 bytes]

What could be the problem?

Thanks!

EDIT: Also tried with Remote Method: RTP/RTSP which fits better I guess, was confused by unicast. But the I get this in the logs:

Here is how I built my rasp pi camera:

Look at the systemd service file I created to see how I run v4l2rtspserver.

For ip cameras, always start with a remote type of ffmpeg when programming the camera in zoneminder. Only use the libvlc or remote source types when/if ffmpeg gives problems.

Thanks for your help!

Now it is working, I guess the h264_i_frame_period was missing.
