Hi @lev, thx for updating the nuget this week. We gave your hap player a try. Unfortunately, it does not work as expected. We tried playing back 4K, 8K and 16K. We encoded the videos using Adobe Media Encoder and FFMPEG. All Hap Q @ 60fps.
4K does work. 8K shows the correct framerate and videolength, but does play at one half to a third of the original speed. Cpu @40-50%, graphics card @ 25%. 16K did not work for us.
We tried this on three different machines. All with fast pcie ssds, 8-16 core processors and capable gpus.
