### RTSP
Frigate can restream your video feed as an RTSP feed for other applications such as Home Assistant to utilize it at `rtsp://<frigate_host>:8554/<camera_name>`. Port 8554 must be open. [This allows you to use a video feed for detection in Frigate and Home Assistant live view at the same time without having to make two separate connections to the camera](#reduce-connections-to-camera). The video feed is copied from the original video feed directly to avoid re-encoding. This feed does not include any annotation by Frigate.
Frigate uses [go2rtc](https://github.com/AlexxIT/go2rtc) to provide its restream and MSE/WebRTC capabilities. The go2rtc config is hosted at the `go2rtc` in the config, see [go2rtc docs](https://github.com/AlexxIT/go2rtc#configuration) for more advanced configurations and features.
#### Birdseye Restream
Birdseye RTSP restream can be enabled at `birdseye -> restream` and accessed at `rtsp://<frigate_host>:8554/birdseye`. Enabling the restream will cause birdseye to run 24/7 which may increase CPU usage somewhat.
### RTMP (Deprecated)
In previous Frigate versions RTMP was used for re-streaming. RTMP has disadvantages however including being incompatible with H.265, high bitrates, and certain audio codecs. RTMP is deprecated and it is recommended to move to the new restream role.
## Reduce Connections To Camera
Some cameras only support one active connection or you may just want to have a single connection open to the camera. The RTSP restream allows this to be possible.
### With Single Stream
One connection is made to the camera. One for the restream, `detect` and `record` connect to the restream.
```yaml
go2rtc:
streams:
rtsp_cam: # <- for RTSP streams
- rtsp://192.168.1.5:554/live0 # <- stream which supports video & aac audio
- ffmpeg:rtsp_cam#audio=opus # <- copy of the stream which transcodes audio to the missing codec (usually will be opus)
http_cam: # <- for other streams
- http://192.168.50.155/flv?port=1935&app=bcs&stream=channel0_main.bcs&user=user&password=password # <- stream which supports video & aac audio
- ffmpeg:http_cam#audio=opus # <- copy of the stream which transcodes audio to the missing codec (usually will be opus)
cameras:
rtsp_cam:
ffmpeg:
output_args:
record: preset-record-generic-audio-copy
inputs:
- path: rtsp://127.0.0.1:8554/rtsp_cam?video=copy&audio=aac # <--- the name here must match the name of the camera in restream
input_args: preset-rtsp-restream
roles:
- record
- detect
http_cam:
ffmpeg:
output_args:
record: preset-record-generic-audio-copy
inputs:

input_args: preset-rtsp-restream
roles:
- record
- detect
```
### With Sub Stream
Two connections are made to the camera. One for the sub stream, one for the restream, `record` connects to the restream.
```yaml
go2rtc:
streams:
rtsp_cam:
- rtsp://192.168.1.5:554/live0 # <- stream which supports video & aac audio. This is only supported for rtsp streams, http must use ffmpeg
- ffmpeg:rtsp_cam#audio=opus # <- copy of the stream which transcodes audio to opus
rtsp_cam_sub:
- rtsp://192.168.1.5:554/substream # <- stream which supports video & aac audio. This is only supported for rtsp streams, http must use ffmpeg
- ffmpeg:rtsp_cam_sub#audio=opus # <- copy of the stream which transcodes audio to opus
http_cam:
- http://192.168.50.155/flv?port=1935&app=bcs&stream=channel0_main.bcs&user=user&password=password # <- stream which supports video & aac audio. This is only supported for rtsp streams, http must use ffmpeg
- ffmpeg:http_cam#audio=opus # <- copy of the stream which transcodes audio to opus
http_cam_sub:
- http://192.168.50.155/flv?port=1935&app=bcs&stream=channel0_ext.bcs&user=user&password=password # <- stream which supports video & aac audio. This is only supported for rtsp streams, http must use ffmpeg
- ffmpeg:http_cam_sub#audio=opus # <- copy of the stream which transcodes audio to opus
cameras:
rtsp_cam:
ffmpeg:
output_args:
record: preset-record-generic-audio-copy
inputs:
- path: rtsp://127.0.0.1:8554/rtsp_cam?video=copy&audio=aac # <--- the name here must match the name of the camera in restream
input_args: preset-rtsp-restream
roles:
- record
- path: rtsp://127.0.0.1:8554/rtsp_cam_sub?video=copy&audio=aac # <--- the name here must match the name of the camera_sub in restream
input_args: preset-rtsp-restream
roles:
- detect
http_cam:
ffmpeg:
output_args:
record: preset-record-generic-audio-copy
inputs:
- path: rtsp://127.0.0.1:8554/http_cam?video=copy&audio=aac # <--- the name here must match the name of the camera in restream
input_args: preset-rtsp-restream
roles:

- path: rtsp://127.0.0.1:8554/http_cam_sub?video=copy&audio=aac # <--- the name here must match the name of the camera_sub in restream
input_args: preset-rtsp-restream
roles:
- detect
```
## Advanced Restream Configurations
The [exec](https://github.com/AlexxIT/go2rtc#source-exec) source in go2rtc can be used for custom ffmpeg commands. An example is below:
NOTE: The output will need to be passed with two curly braces `{{output}}`
```yaml
go2rtc:
streams:
stream1: exec:ffmpeg -hide_banner -re -stream_loop -1 -i /media/BigBuckBunny.mp4 -c copy -rtsp_transport tcp -f rtsp {{output}}
```
## Go2rtc Exec
Go2rtc offers the ability to [run a full command with exec](https://github.com/AlexxIT/go2rtc#source-exec) and calls for `{output}` at the end of the stream. Due to frigate's handling of templates, the output will need to be passed as `{{output}}`.
ex:
```yaml
go2rtc:
streams:
test: exec:ffmpeg -hide_banner -re -stream_loop -1 -i /media/BigBuckBunny.mp4 -c copy -rtsp_transport tcp -f rtsp {{output}}
```
