Unfortunately not…
The error seems to happen in EVRCustomPresenter::SetMediaType when the handler is fetching the Video Samples; I haven’t dug deeper down the rabbithole yet. I bailed and tried to get VLC or FFMPEG working as a video player, but both of those have also resulted in deep rabbitholes…
Many of the helper functions are lifted directly from the Windows Media Foundation examples from 2016, so it seems most likely to me that something changed in the Windows API or COM Interface, though that’s really just a hunch.
I may take a deeper look this week at it; if you find another video player that’s working out-of-the-box with the latest VS2019/C++17, I’d love to take a look…
