Purpose

Remote Desktops of course

Test Clients

  • Apache Guacamole via docker compose running in podman on an alpine vm in qemu(proxmox)
  • msct - Windows 11 Home
  • (Dev)olutions RDM - Not used for any logs below

Test environments

Sources

  • Alpine 3.18
  • KDE Plasma, Xorg >= 3.19, Pulseaudio

Default alpine XRDP results

It works everywhere. Compiling the pulseaudio audio module is a bit annoying. This problem remains. Video performance is only acceptable in tiny windows in the corner, is better on some clients than other (guacamole has the worst performance) No h264, no GL by default.

Default alpine with modified APKBUILD to --enable-glamor

Still works everywhere, and now GL works, glxgears is the most fun video game, it gets beat around 55hz. Installed vdpau and mesa for VirGL, was able to get mpv to claim it was hardware decoding.

Client Performance still unacceptable. Fullscreen video is worse than bad.

Looking for progress

There's a fork that's being working on by Nexarian that enables h264.

The place to start seems to be mainline merge branch . This is where the APKBUILDS above start. They download with git and and configure; it all compiles.

After sorting Nexarian's branches by commit date, it seems there was a patch to it not long ago, but there's almost daily commits to the mainline_merge_shm branch. for the past few days! Very awesome!

I tried that yesterday and the results were not good. More segfaults.

Today they're getting better. this is the result.

xrdp_h264_shm

11/17/2023 ~ noon MST

Guacamole xrdp_h264_shm Guacamole is much slower rendering than with regular xrdp + glamor. Still does not use h264. heavily suspect its the enable-debug command lines. Logs

Current Network Visualization MSCT does start h264. Logs

  • 11/17/2023 - Build failed due to FIFO * instead of struct fifo *, manually patched, no screen. Error reports rdpCapture3: WARNING -- Shared memory is not configured. Aborting capture!
  • 11/18/2023 - New commit fixed build error and made some changes, still the same error about Shared Memory from yesterday and a black screen with msct.exe

Logs

Current Issues

  • Alpine's abuild appears to strip symbols by default so symbols are stripped from logs and errors. Very annoying. I've added !strip to the APKBUILDS for future tests.
  • !strip still seems to remove debug symbols.
