[HW Accel Support]: hwaccel not detected on startup in logs, yet intel vaapi stats show in dashboard

[ioExpander]

Describe the problem you are having

Hi. When starting frigate I see in the logs that there might be an issue with hwaccel :

frigate.util.services WARNING : Did not detect hwaccel, using a GPU for accelerated video decoding is highly recommended

However I see some intel-vaapi stats in the system metrics in the GPU section with <1% usage (as shown in the screenshot). How can I check if the GPU is actually being used ? Or debug this further ?

I did not see this Warning message in the same setup using the previous version of Frigate (0.13) on that same setup.

My setup is :

• Proxmox LXC privileged
• Ubuntu 2404 server image
• Frigate running Docker compose

Thank you.

You should set preset-vaapi at the global level so it is used for everything

[ioExpander]

thank you that did the trick to remove the Warning message from the startup logs. For future reference I added :

ffmpeg:
  hwaccel_args: preset-vaapi

to my top level config. According to the docs if not set this should have fallback to "auto" detection but it seems that this did not work on my setup ?

[NickM-27]

yes, for some reason the auto detection did not detect working hwaccel, but that is why the warning was added in 0.14
