Any hint how I could diagnose the problem?
This should be the Intel 4500 integrated gpu, which is part of the i915/i965 family. It needs: - an intel kernel module - X11 running the intel video driver - libva-drm2 - libva-x11-2 - libva2 - i965-va-driver It will support MPEG2 accelerated decoding but not H264, H265 or any of the newer codecs -- and Youtube may not be supplying old codecs these days. -dsr-
