      Attached is a sample project that creates a C++ side QML object VideoSinkListener that attaches itselt to VideoOutput.videoSink.videoFrameChanged(). Works correctly on Windows but fails on Android with the following error:

      F libvideosink-test_arm64-v8a.so: Cannot make QOpenGLContext current in a different thread
F libc    : Fatal signal 6 (SIGABRT), code -6 in tid 28846 (qtMainLoopThrea)
