Describe the bug

I see no signs of hardware decoding when streaming a game. There is a noticeable input lag too.

To Reproduce

1. Start gfn-electron and launch your favourite game.
2. Wait until the stream begins.
3. Observe your GPU usage with an appropriate tool (intel_gpu_top in my case).

Right after installation

Additional context

The graphics card is Intel® UHD Graphics (CML GT2). Hardware decoding works for me in Chrome with only one additional flag added: -enable-features=VaapiVideoDecodeLinuxGL. I leave out --use-gl, however, I verified that egl does not work and angle does. These are not the same as used by gfn-electron, so I tried the default setting and flags set as above by tweaking the source, in both cases without success. You can see from the screenshot above that hardware decoding does not work.
