QMultiMedia thumbnail extraction

[Rory_1]

I need to efficiently extract thumbnails from videos. I am currently connecting to the QVideoSink::videoFrameChanged signal, where I convert the first frame to a QImage. This is cumbersome, slow and broken (see topic).

Is there another way to get the first frame? If not, could a function be added to do this without playing the video? FFmpeg appears to have this functionality.

Is there a workaround to the failed-to-get-textures error?

MacOS and Win11, Qt 6.6.0 beta4 and 6.5.1
