Regarding the #postmarketos 24.06 release (congrats and thanks to all contributors!) I wanted to add a detail that I think wasn't really mentioned in the posts I saw so far: this release come with #libcamera + #pipewire support by default - even if #pulseaudio is used for audio.
That means that screensharing on #wayland should work OOTB and - more crucially - that a camera stack is in place that allows a much greater number of apps to use cameras - including sandboxed ones.

Disregard my previous post, I figured it out - here is a pure #Wayland desktop running on #Android, with a #Pipewire backend that is then being read by #GStreamer in a proot, which is then read by GStreamer on the host device through a FIFO (as raw YUV420 frames). It works, and all without X!

If you are looking for a tool to let you benchmark your PipeWire pipelines, test things during development or realitime performance graphs then maybe coppwr is the PipeWire tool you been looking for, check it out on Flathub:
