weylus adb with little latency without wifi

[Shallow-Seek]

Weylus with ADB setup can have little latency even in video mode, but no one on the internet mentioned this seemingly. Even the demo in readme.md shows a substantial latency, hence giving people the wrong impression about Weylus's potential on latency, so here are my shout-out to Weylus on that and my setup to achieve that.

I run Weylus on a Linux with Nvidia driver and use a Samsung product/S Pen as input.

1. Choose the correct browser. Some browsers, like Firefox, won't recognize the S-Pen as a stylus, and register S-Pen strokes as touch, so that you have to enable touch to draw with the S-Pen and you won't have palm rejection. I simply use the built-in Samsung browser.
2. Start Weylus
3. Run the following:

adb reverse tcp:1701 tcp:1701
adb reverse tcp:9001 tcp:9001

4. Open http://localhost:1701 on your tablet's browser, and set the min frame interval as min 1 ms.
5. Enable uinput there to have pressure sensitivity.

I tested it on Xournal++. The latency is much better than the wireless setup.
There is another feature of Weylus that could be very useful.
When you turn off the video, you have a mode like that of a writing board. However, there are two problems that make this not very useful.

1. The strokes will fade away shortly.
2. The writing board is stretched and there is no option to change that, so the writings will be skewed in Xournal.
