 +==== go2rtc ==== 
 + 
 +I initially tried this setup using go2rtc instead of mediamtx, but ran in to a problem where only 1 client could join and only at the start of the stream. See  [[https://github.com/RPi-Distro/ffmpeg/pull/10]] 
 + 
 +==== Frigate ==== 
 + 
 +If you want to add this camera to Frigate, the rtsp stream needs to be in yuv420p format. 
 + 
 +This requires the video to be in a resolution divisible by 2 (the default resolution is 154x207). 
 + 
 +I used the answer from [[paths:   # example:   # my_camera:   #   source: rtsp://my_camera   cam:     runOnInit: ffmpeg -f v4l2 -i /dev/video5 -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2" -c:v libx264 -pix_fmt yuv420p -preset ultrafast -f rtsp rtsp://localhost:$RTSP_PORT/$MTX_PATH   # Settings under path "all_others" are applied to all paths that|here]] which will crop it to 154x206. 
 + 
 +<code - mediamtx.yml> 
 +  cam: 
 +    runOnInit: ffmpeg -f v4l2 -i /dev/video5 -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2" -c:v libx264 -pix_fmt yuv420p -preset ultrafast -f rtsp rtsp://localhost:$RTSP_PORT/$MTX_PATH 
 +</code> 
 + 
 +In the Frigate config: 
 + 
 +<code -> 
 +  Seek: 
 +    ffmpeg: 
 +      inputs: 
 +        - path: rtsp:192.168.1.100:8554/cam  
 +          roles: 
 +            - record 
 +    detect: 
 +      enabled: false 
 +</code> 
 + 
 +==== Visual camera ==== 
 + 
 +The Seek Scan includes a visual camera as well. It's not very high quality. 
 + 
 +On my system it was automatically set up as /dev/video0 
 + 
 +Use the [[https://github.com/bluenviron/mediamtx?tab=readme-ov-file#generic-webcam|default usb webcam config.]] 
 + 
 +Seek_viewer has a default image rotation. To have the visual camera match the rotation of the thermal camera, I used the transpose=2 option. 
 + 
 +<code - mediamtx.yml> 
 +  vcam: 
 +    runOnInit: ffmpeg -f v4l2 -i /dev/video0 -vf "transpose=2" -c:v libx264 -pix_fmt yuv420p -preset ultrafast -b:v 600k -f rtsp rtsp://localhost:$RTSP_PORT/$MTX_PATH
