Live Gamer 4K Linux driver

Based on the Linux driver for the CL511HN which can be downloaded here: Generic_Ubuntu_CL511HN_Drv_1.0.0031.zip

The CL511HN and GC573 (Live Gamer 4K) are very similar and their drivers are mostly interchangable. Though the firmware differences mean that some modes won't work on the LG4K.

This was tested on Ubuntu 20.04 LTS and Fedora 32. Linux distributions other than Ubuntu (such as Fedora) might require the patches found on the fedora branch.

Caveats:

Driver needs to be recompiled/installed manually every time there's a kernel update
RGB LEDs are not supported and will keep flashing red
Scaler doesn't seem to work so selected resolution has to match input resolution

How to

clone git repository
run ./build.sh
- Note: switch to fedora branch if it doesn't compile and try again
run sudo ./install.sh
run sudo modprobe cx511h or reboot

ToDo

~~Make driver load automatically~~
Maybe see if we can send a signal to turn off the LEDs by looking at the Windows driver
Check some audio issues in OBS and see why RGB24 doesn't work in there either

VFL_TYPE_VIDEO error occurs on build.sh

I am encountering an error on Linux Mint 20.3 Cinnamon when running the build.sh script. I am assuming that the master branch is what I should be using given that I am on Mint.

I am unsure if this error could be from previously installing the drivers from the base repository, or if it could be due to installing drivers on Windows, as I saw in a previous thread that downgrading the firmware was involved in getting things to work.

Here is the error I am receiving:

/home/user/Downloads/lg4k-linux-master-update/driver//utils/v4l2/v4l2_model_device.c:155:28: error: ‘VFL_TYPE_VIDEO’ undeclared (first use in this function); did you mean ‘VFL_TYPE_RADIO’?
  155 |               devicetype = VFL_TYPE_VIDEO;
      |                            ^~~~~~~~~~~~~~
      |                            VFL_TYPE_RADIO

make: *** [Makefile:66: build] Error 2
make: Leaving directory '/home/user/Downloads/lg4k-linux-master-update/driver'
cp: cannot stat 'driver/gc573.ko': No such file or directory

The driver that this version was forked from accepts the captured audio at 41000kz, when 48000kz is expected, causing audio to be slowed down and lower pitched. I am looking forward to trying this updated driver to see if it would fix this audio bug. Any help appreciated.
