Subject: [PATCH] Update hardware_acceleration.md

Just an update with some of my personal experiences using Frigate with a Raspberry Pi 4 and an Intel Celeron N5100 system.

+##### H.264 and H.265 support
+**NOTICE**: Raspberry Pi 3 does not support hardware acceleration of H.265. H.265 can use a large amount of compute resources on the Raspberry Pi 3 and 4, in some cases it might be better to use H.264 streams.

 ### Intel-based CPUs

-VAAPI supports automatic profile selection so it will work automatically with both H.264 and H.265 streams. VAAPI is recommended for all generations of Intel-based CPUs if QSV does not work.
+VA-API (Open Source Video Acceleration API) supports automatic profile selection so it will work automatically with both H.264 and H.265 streams. VA-API is recommended for all generations of Intel CPUs. Dedicated Quick Sync Video hardware for hardware-accelerated video encoding and decoding is supported with VA-API where available.

-**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=i965` to your docker-compose file or [in the frigate.yml for HA OS users](advanced.md#environment_vars).
