I would love to see this happen as well.

I did attempt to build it and tweak the Cargo.toml with gtk4 and the latest versions of other packages, but the meson/ninja build stuff I'm unfamiliar with and it isn't working for me on Fedora Silverblue.

The biggest issue might be to have a usable gtk4-compatible video sink. I'm not sure what's the current state about this in GStreamer, needs to be investigated...

This might be the way to handle video rendering, https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/tree/main/video/gtk4
