In order to reproduce it, just download the test video
https://drive.google.com/uc?export=download&id=1Iiv31GZzTM0dEOoyNS2Rgnt-ccGXNWvE

and open it in mediaplayer example.
If the reference doesn't work, it should be reproduced with other high quality videos (this one is HDR 60fps with HEVC codec)

AR: the playback is bumpy, frames are rendered in the incorrect order.
ER: smooth video playback

Hints.
The most probable reason is the function D3D11TextureConverter::getTextures,
which converts each ffmpeg frame encapsulating ID3D11Texture2D to D3D11 frame for direct rendering. This is a kind of optimization, you may turn it off to make the example work, if always return nullptr from getTextures.
Ideally, we should investigate the root of the problem and fix the function. If it's impossible by some reason, investigate how much the optimization affects the performance and probably turn it off for some cases.
