**NOTICE**: If you are using the addon, you may need to turn off `Protection mode` for hardware acceleration. If you are using the HA addon, you may need to use the full access variant and turn off `Protection mode` for hardware acceleration.

If running Frigate in docker, you either need to run in priviliged mode or be sure to map the /dev/video1x devices to Frigate If running Frigate in Docker, you either need to run in privileged mode or
map the `/dev/video*` devices to Frigate. With Docker compose add:
```yaml ```yaml
docker run -d \ services:
--name frigate \ frigate:
... ...
--device /dev/video10 \ devices:
ghcr.io/blakeblackshear/frigate:stable - /dev/video11:/dev/video11
``` ```
Or with `docker run`:
```bash
docker run -d \
--name frigate \
...
--device /dev/video11 \
ghcr.io/blakeblackshear/frigate:stable
```
`/dev/video11` is the correct device (on Raspberry Pi 4B). You can check
by running the following and looking for `H264`:
```bash
for d in /dev/video*; do
echo -e "---\n$d"
v4l2-ctl --list-formats-ext -d $d
done
```
Or map in all the `/dev/video*` devices.
