[HW Accel Support]:

[Andr3WTF]

Describe the problem you are having

When i'm trying enable hw acceleration, camera in fragate stop capturing frames and shows only black screen... Without it, everuthing seems working fine. I'm using intel compute card with N4200 cpu, apollo lake, intel hd505.
https://www.intel.com/content/www/us/en/products/sku/95592/intel-pentium-processor-n4200-2m-cache-up-to-2-50-ghz/specifications.html
I trying use #environment_vars: , but no luck. Can you point me where i need dig further? Kind regards, Andrew.

[NickM-27]

what is /dev/video0, a webcam?

[Andr3WTF]

Yes, it is...

[NickM-27]

with hwaccel commented out the logs still show lots of errors and the ffprobe isn't working. I'm not sure how well hwaccel can be utilized here but I think your best bet would be to use go2rtc to restream the webcam data as rtsp

[Andr3WTF]

if i do that, stream in frigate became unavalible, i can watch it only in go2rtc addon... It's possible made it work in both?

[NickM-27]

Let's see the logs, frigate should be accessing it from go2rtc
