+Intel CPUs with build in graphics (non-F variants) since 5th generation have at least h264 decoding support. Once you've configured it and restarted frigate, verify that it's working by running `intel_gpu_top` - if everything is set up correctly, you should see non-zero load on `Video` and/or `VideoEnhance`.

 **NOTICE**: With some of the processors, like the J4125, the default driver `iHD` doesn't seem to work correctly for hardware acceleration. You may need to change the driver to `i965` by adding the following environment variable `LIBVA_DRIVER_NAME_JELLYFIN=i965` to your docker-compose file.
