Add a video background [Feature Request]

[caleb87]

Love this project! It would be awesome if the background could be a video loop. Is there a patreon or anything to support the project?

I see that it's shown on the home page video, but I don't see any where in the docs to add it. Any help on how to add a mp4 as background?

I guess I've drank too much coffee today... 🐎
Wish this was built in though

### Animated Backgrounds
For an animated transparent background implementation, I recommend [anipaper](https://github.com/Theldus/anipaper), which will play a video of your choice in a loop. anipaper should be run with the following options enabled:
- `-b` (Borderless Fullscreen): Since this method requires a compositor, we will need to run anipaper as a borderless fullscreen window rather than as a wallpaper
- `-p` (Pause): We will need to pause the playback when the application launches, and resume it after it finishes
- `-d` (Hardware decoding): This will keep the CPU use as low as possible, and consequently fan noise and power consumption. Requires the hardware device name as an argument. This option is not absolutely required, but you should use it if your hardware is supported.
