 PS. Additionally WebRTC will try to use the 8555 UDP port for transmit encrypted media. It works without problems on the local network.

+# Expr
+
+[Expr](https://github.com/antonmedv/expr) - expression language and expression evaluation for Go.
+
+- [language definition](https://expr.medv.io/docs/Language-Definition) - takes best from JS, Python, Jinja2 syntax
+- your expression should return a link of any supported source
+- expression supports multiple operation, but:
+  - all operations must be separated by a semicolon
+  - all operations, except the last one, must declare a new variable (`let s = "abc";`)
+  - the last operation should return a string
+- go2rtc supports additional functions:
+  - `fetch` - JS-like HTTP requests
+  - `match` - JS-like RegExp queries
+
+## Examples
+
+**Two way audio for Dahua VTO**
+
+```yaml
+streams:
+  dahua_vto: |
+    expr: let host = "admin:password@192.168.1.123";
+    fetch("http://"+host+"/cgi-bin/configManager.cgi?action=setConfig&Encode[0].MainFormat[0].Audio.Compression=G.711A&Encode[0].MainFormat[0].Audio.Frequency=8000").ok
+        ? "rtsp://"+host+"/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif" : ""
+```
+
+**dom.ru**
+
+You can get credentials via:
+
+- https://github.com/alexmorbo/domru (file `/share/domru/accounts`)
+- https://github.com/ad/domru
+
+```yaml
+streams:
+  dom_ru: |
+    expr: let camera = "99999999"; let token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; let operator = 99;
+    fetch("https://myhome.novotelecom.ru/rest/v1/forpost/cameras/"+camera+"/video", {

+# GoPro
+
+Supported models: HERO9, HERO10, HERO11, HERO12.  
+Supported OS: Linux, Mac, Windows, [HassOS](https://www.home-assistant.io/installation/)
+
+The other camera models have different APIs. I will try to add them in the next versions.
+
+## Config
+
+- USB-connected cameras create a new network interface in the system
+- Linux users do not need to install anything
+- Windows users should install the [network driver](https://community.gopro.com/s/article/GoPro-Webcam)
+- if the camera is detected but the stream does not start - you need to disable firewall
+
+1. Discover camera address: WebUI > Add > GoPro
+2. Add camera to config
+
+```yaml
+streams:
+  hero12: gopro://172.20.100.51
+```
