+
+This project contains a userspace driver for the [AverMedia LGX2 (GC551)](https://avermedia.com/LGX2) as well support for the [AverMedia LGX (GC550)](https://avermedia.com/LGX).
+
+It can be used to display the captured video and audio in a standalone window or
+to forward the captured video and audio to a virtual video capture device.
+
+## Building
+To build the project, you will need:
+* CMake
+* Libusb
+* Libpcap
+* SDL2
+* V4L2Loopback

+and it will eventually display a window that will then start to display captured frames.
+
+In my limited testing, certain devices may need to be re-plugged in after the application has 
+started. For example, a Nintendo Switch will not recognise the LGX/LGX2 as an output source until
+it is undocked and re-docked.

+by pressing `F` and to exit fullscreen by pressing `G`.
+
+### Gathering diagnostic information
+To help diagnose problems that may be fixed in the future, when submitting an issue
+please try to give as much information about your setup as possible and in the case of
+inadequate video or audio output, run the userspace driver with the `-v` switch enabled.
+
+With the `-v` switch enabled, the driver will output information regarding time taken to
+process frame data and time taken to render both audio and video.

+## Running with V4L2 Output and Pulseaudio Output
+### V4L2 Output setup
+To output video to a virtual webcam output source, load the V4L2 Loopback Linux module with an easy to identify device
+number:
+
+```bash
+sudo modprobe v4l2loopback video_nr=99 exclusive_caps=1 card_label="LGX2"
+```
+
+You should now see `/dev/video99` exists:
+
+```bash
+ls /dev/video99
+/dev/video99
+```
+
+### Pulseaudio Setup
+Pulseaudio can be configured by issuing the following commands:
+```bash
+pactl load-module module-null-sink sink_name=lgx2 sink_properties=device.description=LGX2
+pactl load-module module-remap-source master=lgx2.monitor source_name=lgx2 source_properties=device.description=LGX2Audio
+```
+This will create an audio sink called `LGX2 Audio Sink` which can be added to OBS as a Pulseaudio output capture device.
+
+**NOTE: Even if you are using the LGX GC550- leaving the names as lgx2 is required and will not affect behaviour.**
+**NOTE: The best way to control the audio volume is to use the gain OBS filter whilst leaving the sink volume at max.**
+
+### Running with configure V4L2 device
+Run the userspace driver with the `-d` option to specify which V4L2Loopback device to use:
+
+```bash
+./lgx2userspace -d /dev/video99
+```
+
+To run using the Pulseaudio sink that you created, use the `-a` switch with the name of the sink:
+
+```bash
+./lgx2userspace -a lgx2
+```
+
+**NOTE: You may need to unplug and replug in your video source.**
+
+Go to OBS or other streaming software and select the LGX2 V4L2 source. You should now see video from the input device being output.
