id: configuring_go2rtc
title: Configuring go2rtc
---
Use of the bundled go2rtc is optional. You can still configure FFmpeg to connect directly to your cameras. However, adding go2rtc to your configuration is required for the following features:
- WebRTC or MSE for live viewing with higher resolutions and frame rates than the jsmpeg stream which is limited to the detect stream
- RTSP (instead of RTMP) relay for use with Home Assistant or other consumers to reduce the number of connections to your camera streams
# Setup a go2rtc stream
First, you will want to configure go2rtc to connect to your camera stream by adding the stream you want to use for live view in your Frigate config file. If you set the stream name under go2rtc to match the name of your camera, it will automatically be mapped and you will get additional live view options for the camera. Avoid changing any other parts of your config at this step. Note that go2rtc supports [many different stream types](https://github.com/AlexxIT/go2rtc#module-streams), not just rtsp.
```yaml
go2rtc:
streams:
back:
- rtsp://user:password@10.0.10.10:554/cam/realmonitor?channel=1&subtype=2
```
The easiest live view to get working is MSE. After adding this to the config, restart Frigate and try to watch the live stream by selecting MSE in the dropdown after clicking on the camera.
### What if my video doesn't play?
If you are unable to see your video feed, first check the go2rtc logs in the Frigate UI under Logs in the sidebar. If go2rtc is having difficulty connecting to your camera, you should see some error messages in the log. If you do not see any errors, then video codec of the stream may not be supported in your browser. If your camera stream is set to H265, try switching to H264. You can see more information about [video codec compatibility](https://github.com/AlexxIT/go2rtc#codecs-madness) in the go2rtc documentation. If you are not able to switch your camera settings from H265 to H264 or your stream is a different format such as MJPEG, you can use go2rtc to re-encode the video using the [FFmpeg parameters](https://github.com/AlexxIT/go2rtc#source-ffmpeg). It supports rotating and resizing video feeds and hardware acceleration. Keep in mind that transcoding video from one format to another is a resource intensive task and you may be better off using the built-in jsmpeg view. Here is an example of a config that will re-encode the stream to H264 without hardware acceleration:
```yaml
go2rtc:
streams:
back:
- rtsp://user:password@10.0.10.10:554/cam/realmonitor?channel=1&subtype=2
- "ffmpeg:back#video=h264"
```
If you can see the video but do not have audio, this is most likely because your camera's audio stream is not AAC. If possible, update your camera's audio settings to AAC. If your cameras do not support AAC audio, you will need to tell go2rtc to re-encode the audio to AAC on demand if you want audio. This will use additional CPU and add some latency. To add AAC audio on demand, you can update your go2rtc config as follows:
```yaml
go2rtc:
streams:
back:
- rtsp://user:password@10.0.10.10:554/cam/realmonitor?channel=1&subtype=2
- "ffmpeg:back#audio=aac"
```
If you need to convert **both** the audio and video streams, you can use the following:
```yaml
go2rtc:
streams:
back:
- rtsp://user:password@10.0.10.10:554/cam/realmonitor?channel=1&subtype=2
- "ffmpeg:back#video=h264#audio=aac"
```
## Next steps
1. If the stream you added to go2rtc is also used by Frigate for the `record` or `detect` role, you can migrate your config to pull from the RTSP restream to reduce the number of connections to your camera as shown [here](/configuration/restream#reduce-connections-to-camera).
1. You may also prefer to [setup WebRTC](/configuration/live#webrtc-extra-configuration) for slightly lower latency than MSE. Note that WebRTC only supports h264 and specific audio formats.

## Limiting Events to Areas of Interest
The best way to limit events to areas of interest is to use [zones](../configuration/zones.md) along with `required_zones` for events and snapshots to only have events created in areas of interest.

This guide walks through the steps to build a configuration file for Frigate. It assumes that you already have an environment setup as described in [Installation](../frigate/installation.md). You should also configure your cameras according to the [camera setup guide](/guides/camera_setup) This guide walks through the steps to build a configuration file for Frigate. It assumes that you already have an environment setup as described in [Installation](../frigate/installation.md). You should also configure your cameras according to the [camera setup guide](/frigate/camera_setup). Pay particular attention to the section on choosing a detect resolution.
### Step 1: Configure the MQTT server (Optional) ### Step 1: Add a detect stream
Use of a functioning MQTT server is optional for Frigate, but required for the home assistant integration. Start by adding the mqtt section at the top level in your config: First we will add the detect stream for the camera:
If using mqtt:
```yaml
mqtt:
host: <ip of your mqtt server>
```
If not using mqtt:
```yaml ```yaml
mqtt: mqtt:
enabled: False enabled: False
```
If using the Mosquitto Addon in Home Assistant, a username and password is required. For example:
```yaml
mqtt:
host: <ip of your mqtt server>
user: <username>
password: <password>
```
Frigate supports many configuration options for mqtt. See the [configuration reference](../configuration/index.md#full-configuration-reference) for more info.
### Step 2: Configure detectors
By default, Frigate will use a single CPU detector. If you have a USB Coral, you will need to add a detectors section to your config.
```yaml
mqtt:
host: <ip of your mqtt server>
detectors:
coral:
type: edgetpu
device: usb
```
More details on available detectors can be found [here](../configuration/detectors.md).
### Step 3: Add a minimal camera configuration
Now let's add the first camera:
```yaml
mqtt:
host: <ip of your mqtt server>
detectors:
coral:
type: edgetpu
device: usb
cameras: cameras:
camera_1: # <------ Name the camera camera_1: # <------ Name the camera

``` ```

### Step 5: Configure hardware acceleration (optional) ### Step 3: Configure hardware acceleration (recommended)
Now that you have a working camera configuration, you want to setup hardware acceleration to minimize the CPU required to decode your video streams. See the [hardware acceleration](../configuration/hardware_acceleration.md) config reference for examples applicable to your hardware. Now that you have a working camera configuration, you want to setup hardware acceleration to minimize the CPU required to decode your video streams. See the [hardware acceleration](../configuration/hardware_acceleration.md) config reference for examples applicable to your hardware.
In order to best evaluate the performance impact of hardware acceleration, it is recommended to temporarily disable detection. Here is an example configuration with hardware acceleration configured for Intel processors with an integrated GPU using the [preset](../configuration/ffmpeg_presets.md):
```yaml ```yaml
mqtt: ... mqtt: ...
detectors: ...
cameras:
camera_1:
ffmpeg: ...
detect:
enabled: False

``` ```
### Step 6: Setup motion masks ### Step 4: Configure detectors
By default, Frigate will use a single CPU detector. If you have a USB Coral, you will need to add a detectors section to your config.
```yaml
mqtt: ...
detectors: # <---- add detectors
coral:
type: edgetpu
device: usb
cameras:
camera_1:
ffmpeg: ...
detect:
enabled: True # <---- turn on detection
...
```
More details on available detectors can be found [here](../configuration/detectors.md).
Restart Frigate and you should start seeing detections for `person`. If you want to track other objects, they will need to be added according to the [configuration file reference](../configuration/index.md#full-configuration-reference).
### Step 5: Setup motion masks
Now that you have optimized your configuration for decoding the video stream, you will want to check to see where to implement motion masks. To do this, navigate to the camera in the UI, select "Debug" at the top, and enable "Motion boxes" in the options below the video feed. Watch for areas that continuously trigger unwanted motion to be detected. Common areas to mask include camera timestamps and trees that frequently blow in the wind. The goal is to avoid wasting object detection cycles looking at these areas.
