This has some potential but I don't have time to finish it ;p

Why, you weren't happy with vnc?
Actually being able to use networking apps like vnc client with peace of mind was one of the benefits of InkBox I thought.

the one inkbox uses now is xorg based so it's slow and heavy
the rust written one didn't worked for me at all

benefits for this one:
- I can apply custom filters which allowed me to do that awesome dithering
- It works
- current not optimised code takes only 30% of the cpu on the kobo

So I tried a few...

***

From tablet:

droidVNC-NG

From kobo:

(rust vnc client)
# einkvnc4 192.168.43.12 5902 --password vncpasswd --contrast 2

%cpu 85-90 for youtube!
Much more than your 30.

***

From laptop:

$ sudo adduser kobo

$ su kobo

* Edit: Also relogged in as user kobo

$ sudo ufw allow proto tcp from 192.168.43.5 to 192.168.43.12 port 5902

$ sudo apt install x11vnc

$ x11vnc -opts

$ x11vnc -storepasswd

$ x11vnc -zeroconf -rfbport 5902 -rfbauth .vnc/passwd -geometry 1400x960 &

From kobo:

# ping 192.168.43.12

(rust vnc client)
# einkvnc4 192.168.43.12 5902 --password vncpasswd --contrast 2

%cpu 10 for text editing.
%cpu 60 for youtube

*very low latency for text editing.
low lag for youtube but not clear like yours.

From kobo chroot:

(x11 vnc client)
# vncviewer -geometry 1400x960+20+60 192.168.43.12::5902 &

%cpu below 5 for text editing.
%cpu below 30 for small unmaximized youtube

*very low latency for text editing.
unviewable youtube in large window.

I can get better editing latency, but not the clarity of your video images.

Note that I have the nia, not the clara which is slower and with not so much ram
And this demo app is written really badly

Updated, made more properly now:

It is fast boi now, sadly more dithering based ghosting because I can't control it?
