[Camera Support]: Restream with go2rtc ERROR: Could not find codec parameters for stream

[spygroove2002]

Describe the problem you are having

Hello,

in order to rotate the image of an camera, I would like to use go2rtc restream function. However, while I can sucessfully access the the go2rtc stream through my browser (i.e. , I'm not able to integrate it as frigate camera. On the Firgate log side I get a "Unable to read frames from ffmpeg process", in the go2rtc log side I get a "Could not find codec parameters for stream" error

• There are several other cameras working nicely - didnt include in logs/config here
• I upgraded to a custom go2rtc build to test if this changes anything, but wit the standard version I get the same error
• The relevant restream can be sucessfully viewed in my browser under http://IP:5000/live/webrtc/stream.html?src=Garden_3_low_rotated

you may try including audio

  streams:
    Garden_3_low:
      - ffmpeg:rtsp://xxx:xxx@192.168.1.169:554/video2

    Garden_3_low_rotated:
      - "ffmpeg:Garden_3_low#video=h264#rotate=270#audio=copy" 

by the way I'd suggest keeping the detect fps at 5, 24 is quite high and frigate does not benefit from such high fps. It does not need to match your cameras fps.

[spygroove2002]

Doesn’t change it. Forgot to mention, it’s a video only stream and it doesn’t seem to be related to the rotation neither. The camera also doesn’t work if I point it to the Garden_3_low stream.

[NickM-27]

seems like the camera is sending bad data in a form that ffmpeg is not able to handle it
