Thank you for the answer !
HAP is not an option for me, because i have not the time to reencode all my material.
I am trying now to play my >4096 h264 files without hardware acceleration on a faster machine
Just to be complete a h264 with >4096 pixel width does not play with hardware acceleration on win 10 machine. (output is black)
Works fine with smaller files. There seems to be a limit with the DXVA component ...
Looking forward to the next version. Then i will encode everything with HAP.
All the best,
