I don’t think I want to officially support it right now, but build fixes to make it work and selectable on Android are welcome.

Naturally, using Qt Multimedia is far more ergonomic than mixing GStreamer's C API into the code, however.

The one thing I want to avoid is what we had in Qt 5, where you could force Qt MM to use a different/custom gstreamer pipeline based on environment variables. That part made maintaining the code base extremely hard. Other than that I’m of course open for patches and improvements. If some integration points are needed, we can discuss those separately, but unless they are trivial, they will probably need to wait until after 6.2.
