Thanks for this and further help on IRC. I now have Pidgin screen sharing (to Amazon Chime¹) working from raw X11, portal and maybe also via gdiscreencapsrc on Windows. That full patch is at http://david.woodhou.se/pidgin-screenshare.patch Or just the latest PipeWire bits, at http://david.woodhou.se/pidgin-share-pipewire.patch I need to tidy up some of the error handling and failure cases. It would be really useful if there was a library somewhere, with a simple function to call for "prompt the user and then give me a GStreamer src element", which worked on all platforms. That's essentially what I've provided in the Pidgin code. Except someone more competent would ideally have written it. Is there somewhere that functionality should live? -- dwmw2 ¹ https://github.com/awslabs/pidgin-chime
