Checklist

I have updated to the latest available Frigate version.
I have cleared the cache of my browser.
I have tried a different browser to see if it is related to my browser.
I have tried reproducing the issue in incognito mode to rule out problems with any third party extensions or plugins I have installed.

Describe the problem you are having

If a camera is viewed or detects motion and therefor is streamed to the overview display an additional ffmpeg process is started in my setup to vacilitate the transcoding from h265 from my reolink camera to a h264 stream via go2rtc.

The video is streamed correctly but after viewing the FFMPEG process keeps running according to "intel_gpu_top".
Closing the Browser Tab or the whole browser has no impact and only a complete restart of frigate removes the process.

Visiting the camera again spawns another process. So after some visits to streaming cams the GPU is overwhelmed.

I would kindly suggest to consider this behaviour as a bug as it uses valuable system resources, basicly forever.

Steps to reproduce

Setup go2rtc to stream as h264 for a h265 camera source
visit camera live stream
ffmped process is started
close tab / Browser / shutdown pc / burn smartphone
Process keeps running

You can try using a newer version of go2rtc and see if that fixes it

This would be a go2rtc bug not a frigate bug

Updated from

go2rtc platform=linux/amd64 revision=b2399f3 version=1.9.2

to

go2rtc platform=linux/amd64 revision=dbe9e4a version=1.9.7

With that i could not replicate the issue above. I would consider this bug to be fixed with the go2rtc update.

Sidenote. REOLINK RTSP implementation is bad. The amount of

github.com/AlexxIT/go2rtc/internal/streams/producer.go:170 > error=EOF url=ffmpeg:trackmix_wide#video=h264#audio=opus#hardware

is eyewatering. Buyers beware.
