Too slow xpra drawing?

[tunatoksoz]

I tried official xpra client, and os-js client. For some reason, os-js client (xpra-html5-client) is performing very poorly. It's like 1 frame per second or less. When I looked into the dev tools, it confirmed my suspicion of 1fps, and i noted base64 image constructions at a similar or slower rate.

Official XPRA client seems to be getting quite a bit of updates, but too sad they don't export it as an NPM'able library nor do they make it easy to use individual bits and pieces.

I will probably do some more digging, but performance difference will probably kill one of my use cases until i can identify the problem.

This is probably the main issue. My version of the xpra library doesn't have the video codec support that is in the official package.

I actually started rewriting the entire thing from bottom up using typescript and with way less influence from the original code. I really should look into that again... it's been quite a while since I touched that.

From purely maintenance pov, the ideal case is xpra-team to create a library that others can use (so you can use it as is). This would help with their updates automatically getting pulled into your wrapper.

But that probably would take a long time and not sure how easy it is for them to do it (or if there's even a use for them).

Mid-way solution is probably copy paste instead of a rewrite, and building a wrapper without modifying code.

You already know these, helping you to think out loud..

For my use case due to time constraints i will probably do VNC and SPICE integration instead, and leave XPRA to be a standalone page i will link into in case i need it.

We are going to move the https://github.com/Xpra-org/xpra-html5 client to a more modern codebase (ES6) and plan on making it more re-usable for external projects as there seems to be quite a few that are re-using it.
We are discussing how best to proceed with that, feel free to join us on this Xpra web client(s) discussion channel: https://discord.com/channels/934131122504343572/939997428696883260

Just a small update on that TS client I mentioned. I found a bit of time to do a little bit more work on it: https://github.com/andersevenrud/xpra-html5-client

@totaam Is that discord invite only or something ? I can't seem to get it. At first I thought it was something on my end, but it's been like a week and I still get "no text channels" error. I'm a total Discord noob though, so maybe there's an option or something ? I would love to join in on this.

@andersevenrud I'm also a discord noob, but I've pinged someone who should be able to sort this out.
The channel should be public.

@andersevenrud sorry he hasn't replied yet, how about this link:
