+- for Linux supported only video for now
+- for macOS you can stream Facetime camera or whole Desktop!
+- for macOS important to set right framerate
+
+```yaml
+streams:
+  linux_usbcam:   ffmpeg:device?video=0&resolution=1280x720#video=h264
+  windows_webcam: ffmpeg:device?video=0#video=h264

 #### Source: Exec
 
 FFmpeg source just a shortcut to exec source. You can get any stream or file or device via FFmpeg or GStreamer and push it to go2rtc via RTSP protocol:
