Thanks to paco3346's comment, I was able to (have Claude AI) make an updated PKGBUILD that works.

as well as splashtop-business-wrapper.sh:

#!/bin/bash
# Wrapper script for splashtop-business
# This ensures the bundled ffmpeg 7.x libraries are used instead of system ffmpeg 8.x

# Set library path to prioritize bundled libraries
export LD_LIBRARY_PATH="/opt/splashtop-business/lib:$LD_LIBRARY_PATH"

# Handle Wayland - Splashtop Business works better with XWayland
# Unset WAYLAND_DISPLAY to force X11/XWayland mode
if [ -n "$WAYLAND_DISPLAY" ]; then
    unset WAYLAND_DISPLAY
fi

# Execute the actual splashtop-business binary
exec /opt/splashtop-business/splashtop-business.bin "$@"

This bundles the correct libraries with splashtop and directs splashtop to use it, while allowing you to just run splashtop-business as normal without explicitly declaring environment variables. Sharing because it worked for me, hopefully it works for you too.

Re: agsimmons0, I had the same infinite loading symptoms, this seemingly resolved it for me.

I can confirm the flatpak works for me. If you were to go forward, I think flatpak would be the way to go.

It works using distrobox (debian:trixie) and then running it with env -u WAYLAND_DISPLAY if you are using Wayland.

Updated to 3.8.0.0 and I don't get the ffmpeg error but the connection attempt hangs and never completes.

I'm looking into if there's anything I can do about this incompatibility from the AUR package side. Ultimately it seems like Splashtop should release an update that fixes the incompatibility, but I have no insight into if or when they would do that.

I'm experimenting with getting it working within a Flatpak here https://github.com/agsimmons/splashtop-business-flatpak where I can pin a specific ffmpeg version. I don't yet have the vbx, h264, or av1 codecs included.

This has been broken for the past ~2 months and I've been in conversation with the support team about it. Here's what I've learned and a fix:

Something changed in ffmpeg and splashtop was built against an older API. The Splashtop support team said 6.1 -> 6.2 is what broke it but I found that 7.x worked and 8.x is what broke it. Regardless, ffmpeg is the issue.

Use the following URLs to pull the older version of ffmpeg and its dependencies.

https://archive.archlinux.org/packages/f/ffmpeg/ffmpeg-2%3A7.1.1-5-x86_64.pkg.tar.zst

https://archive.archlinux.org/packages/l/libvpx/libvpx-1.15.0-1-x86_64.pkg.tar.zst

https://archive.archlinux.org/packages/r/rav1e/rav1e-0.7.1-1-x86_64.pkg.tar.zst

https://archive.archlinux.org/packages/x/x264/x264-3%3A0.164.r3108.31e19f9-3-x86_64.pkg.tar.zst

Open each one of these and copy all the libs into a new folder.

You can extract everything with all the symlinks but I found the following to be the list of filenames that splashtop specifically looks for:

libavcodec.so
libavdevice.so
libavfilter.so
libavformat.so
libavutil.so    // this is the only one that needed 2 filenames for the same lib
libavutil.so.59 //
libpostproc.so
librav1e.so.0.7
libswresample.so.5
libswscale.so
libvpx.so.9
libx264.so.164

Finally, launch with

 LD_LIBRARY_PATH={/path/to/your/splashtop-libs}:$LD_LIBRARY_PATH splashtop-business

Clean install of Omarchy. env QT_SCALE_FACTOR=2 WAYLAND_DISPLAY=wayland-0 Running this in Xwayland fails on client connection with the following error:

Can the post_remove be updated to remove the installed service /usr/lib/systemd/system/SRUsb.service ?
