title: Hardware Acceleration
---

It is recommended to update your configuration to enable hardware accelerated decoding in ffmpeg. Depending on your system, these parameters may not be compatible. More information on hardware accelerated decoding for ffmpeg can be found here: https://trac.ffmpeg.org/wiki/HWAccelIntro

### Raspberry Pi 3/4

:::caution

There is currently a bug in ffmpeg that causes hwaccel to not work for the RPi kernel 5.15.61 and above. For more information see https://github.com/blakeblackshear/frigate/issues/3780

:::

Ensure you increase the allocated RAM for your GPU to at least 128 (raspi-config > Performance Options > GPU Memory).
**NOTICE**: If you are using the addon, you may need to turn off `Protection mode` for hardware acceleration.

```yaml
ffmpeg:
  hwaccel_args: preset-rpi-64-h264
```

### Intel-based CPUs (<10th Generation) via Quicksync

```yaml
ffmpeg:
  hwaccel_args: preset-vaapi
```
**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).

### Intel-based CPUs (>=10th Generation) via Quicksync

```yaml
ffmpeg:
  hwaccel_args: preset-intel-qsv-h264
```

### AMD/ATI GPUs (Radeon HD 2000 and newer GPUs) via libva-mesa-driver

**Note:** You also need to set `LIBVA_DRIVER_NAME=radeonsi` as an environment variable on the container.

```yaml
ffmpeg:
  hwaccel_args: preset-vaapi
```

### NVIDIA GPU

[Supported Nvidia GPUs for Decoding](https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new)

These instructions are based on the [jellyfin documentation](https://jellyfin.org/docs/general/administration/hardware-acceleration.html#nvidia-hardware-acceleration-on-docker-linux)

Add `--gpus all` to your docker run command or update your compose file.
If you have multiple Nvidia graphic card, you can add them with their ids obtained via `nvidia-smi` command
```yaml
services:
  frigate:
    ...
    image: blakeblackshear/frigate:stable
    deploy:    # <------------- Add this section
      resources:
        reservations:
          devices:
            - driver: nvidia
              device_ids: ['0'] # this is only needed when using multiple GPUs
              count: 1 # number of GPUs
              capabilities: [gpu]
```

The decoder you need to pass in the `hwaccel_args` will depend on the input video.

A list of supported codecs (you can use `ffmpeg -decoders | grep cuvid` in the container to get a list)

```shell
 V..... h263_cuvid           Nvidia CUVID H263 decoder (codec h263)
 V..... h264_cuvid           Nvidia CUVID H264 decoder (codec h264)
 V..... hevc_cuvid           Nvidia CUVID HEVC decoder (codec hevc)
 V..... mjpeg_cuvid          Nvidia CUVID MJPEG decoder (codec mjpeg)
 V..... mpeg1_cuvid          Nvidia CUVID MPEG1VIDEO decoder (codec mpeg1video)
 V..... mpeg2_cuvid          Nvidia CUVID MPEG2VIDEO decoder (codec mpeg2video)
 V..... mpeg4_cuvid          Nvidia CUVID MPEG4 decoder (codec mpeg4)
 V..... vc1_cuvid            Nvidia CUVID VC1 decoder (codec vc1)
 V..... vp8_cuvid            Nvidia CUVID VP8 decoder (codec vp8)
 V..... vp9_cuvid            Nvidia CUVID VP9 decoder (codec vp9)
```

For example, for H264 video, you'll select `preset-nvidia-h264`.

```yaml
ffmpeg:
  hwaccel_args: preset-nvidia-h264
```

If everything is working correctly, you should see a significant improvement in performance.
Verify that hardware decoding is working by running `nvidia-smi`, which should show the ffmpeg
processes:

:::note

nvidia-smi may not show ffmpeg processes when run inside the container [due to docker limitations](https://github.com/NVIDIA/nvidia-docker/issues/179#issuecomment-645579458)
