Expose Camera Stream Source

Home Assistant integration to expose an API to retrieve the camera stream source URL.

For example, it allows you to import Tuya, Nest and possibly other cameras to go2rtc and Frigate.

Note, however, that this integration will only work if you are already able to view your camera stream in Home Assistant using HLS.

For cameras that exclusively only work via WebRTC (through the RTSPToWebRTC Home Assistant integration), this method will not help. It is the case for some specific Nest and Tuya cameras, for example.

If that is your case:

• Nest WebRTC-native cameras are supported natively in go2rtc, see here for more details.
• Tuya WebRTC-native cameras are not supported either by Home Assistant or go2rtc. If you need it, you can express your need in:
  • home-assistant/core#68503
  • AlexxIT/go2rtc#315

Installation

Easiest install is via HACS:

1. Click the button above, and install this integration via HACS. Do not try to configure it yet.

2. Restart Home Assistant.

3. Add the following to your configuration.yaml file:

   expose_camera_stream_source:

4. Restart Home Assistant again.

Now the integration should be active.

Importing cameras from Home Assistant to go2rtc and Frigate

This integration can be used to import cameras from Home Assistant to go2rtc and Frigate, including cameras which does not expose a RTSP feed by default, like some Tuya and Nest cameras.

When go2rtc is running within Frigate

This is the case for Frigate 0.12 and above.

If you are running go2rtc within the Frigate add-on, you can use the following configuration:

# /config/frigate.yaml

go2rtc:
  streams:
    my_camera:
      - echo:bash /config/custom_components/expose_camera_stream_source/get_stream.sh camera.my_camera

cameras:
  my_camera:
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/my_camera?video
          input_args: preset-rtsp-restream-low-latency
          roles:
            - detect

Where camera.my_camera is the Home Assistant entity ID for the camera that you want to import the stream from.

If you are running Frigate through docker, read here and make the necessary adaptations.

When go2rtc is installed as an add-on

Click here to show

If you are running go2rtc as an add-on in Home Assistant, the process is a little simpler (if not, check here). Here's an example of the go2rtc configuration:

# /config/go2rtc.yaml

streams:
  my_camera:
    - echo:bash /config/custom_components/expose_camera_stream_source/get_stream.sh camera.my_camera

Where camera.my_camera is the Home Assistant entity ID for the camera that you want to import the stream from.

The get_stream.sh script is included by this integration. You can use it to get the stream source URL for any camera in Home Assistant from inside of any add-on.

Then, you can consume your go2rtc's my_camera stream in other applications like Frigate or other NVRs:

• rtsp://192.168.1.10:8554/my_camera

Where 192.168.1.10 is the IP which you can access the go2rtc interfaces (for add-on users it's the same IP as your Home Assistant).

Tip: Try to first play the RTSP link above in VLC before adding to Frigate or other NVRs, to ensure everything is working up to this point.

When go2rtc is running via docker

Click here to show

When go2rtc is not running as a Home Assistant add-on, you need to prepare a script and mount it to the go2rtc container. Here is how the script should look like:

#!/usr/bin/env bash

set -eu

HA_TOKEN="${HA_TOKEN:?"HA_TOKEN is not set, make sure to have this environment variable set with your Home Assisant long-lived token."}"
entity_id="${1}"

exec curl -fsSL -H "Authorization: Bearer ${HA_TOKEN}" "http://192.168.1.10:8123/api/camera_stream_source/${entity_id}"

Where 192.168.1.10 is your Home Assistant's IP address.

Paste the content above in a file named get_ha_stream.sh. For this example, we will store the file at your home folder (~/get_ha_stream.sh). Then give it execution permission with the following command:

chmod +x ~/get_ha_stream.sh

You will also need a long-lived access token from Home Assistant. To generate one:

1. Go to your Home Assistant profile page:
2. Scroll down to Long-Lived Access Token, and click in Create Token.
3. Give it a name, like go2rtc and press Ok.
4. Copy your generated access token and save it. We will need it soon.

Now, you need to make sure the script you created earlier is mounted in the go2rtc container, and your token is added as the HA_TOKEN environment variable. If you use Docker Compose, you just need to add something like the below in your configuration:

# docker-compose.yaml

services:
  go2rtc:
    image: alexxit/go2rtc
    network_mode: host
    restart: always
    volumes:
      - "~/go2rtc.yaml:/config/go2rtc.yaml"
+     - "~/get_ha_stream.sh:/config/get_ha_stream.sh"
+   environment:
+     HA_TOKEN: paste-your-token-here

And here is an example of the go2rtc configuration:

# go2rtc.yaml

streams:
  my_camera:
    - echo:/config/get_ha_stream.sh camera.my_camera

Where camera.my_camera is the Home Assistant entity ID for the camera that you want to import the stream from.

Then, you can consume your go2rtc's my_camera stream in other applications like Frigate or other NVRs:

• rtsp://192.168.1.10:8554/my_camera

Where 192.168.1.10 is the IP which you can access the go2rtc interfaces (for add-on users it's the same IP as your Home Assistant).

Tip: Try to first play the RTSP link above in VLC before adding to Frigate or other NVRs, to ensure everything is working up to this point.

When go2rtc is running via the WebRTC integration

Click here to show

When go2rtc is not running as a Home Assistant add-on neither via an add-on, but as part of the WebRTC integration, you need to prepare a script in your /config folder.

First, you will need a long-lived access token from Home Assistant. To generate one:

1. Go to your Home Assistant profile page:
2. Scroll down to Long-Lived Access Token, and click in Create Token.
3. Give it a name, like go2rtc and press Ok.
4. Copy your generated access token and save it. We will need it soon.

Then, you can create the script. Here is how the script should look like:

#!/usr/bin/env bash

set -eu

HA_TOKEN="<put your long-lived access token here>"
entity_id="${1}"

exec curl -fsSL -H "Authorization: Bearer ${HA_TOKEN}" "http://127.0.0.1:8123/api/camera_stream_source/${entity_id}"

Paste the content above in a file named get_ha_stream.sh, and place it in Home Assistant's /config folder. Do not forget to put your long-lived access token in the script's placeholder.

Then, give it execution permission with the following command:

chmod +x ~/get_ha_stream.sh

And here is an example of the go2rtc configuration:

# go2rtc.yaml

streams:
  my_camera:
    - echo:/config/get_ha_stream.sh camera.my_camera

Where camera.my_camera is the Home Assistant entity ID for the camera that you want to import the stream from.

Then, you can consume your go2rtc's my_camera stream in other applications like Frigate or other NVRs:

• rtsp://192.168.1.10:8554/my_camera

Where 192.168.1.10 is the IP which you can access the go2rtc interfaces (for add-on users it's the same IP as your Home Assistant).

Tip: Try to first play the RTSP link above in VLC before adding to Frigate or other NVRs, to ensure everything is working up to this point.
