I wondered that myself so I made one with ffmpeg/libx264. Further testing shows that 4080x4080 works and >= 4082x4082 fails. I tried getting libx264 to make constrained baseline but no difference. These 2 were made like ffmpeg -i a-2160p60.mkv -vf scale=w=4080:h=4080 -c:v libx264 -vframes 10 x264-4080.mkv as they are only 10 frames tested like - mpv --speed=0.1 -fs --hwdec=vdpau x264-4080.mkv While here a shameless bump of a similar VCE issue :-) I don't know the precise fail point for VCE but 3840x2160 fails 2560x1440 works. https://bugs.freedesktop.org/show_bug.cgi?id=91281
