Kodi in LE v8/v9 uses VDPAU for nVidia cards, which is no longer developed, and VDPAU only supports 8-bit HEVC. LE v10 will not support X11, so unless nVidia get their VDPAU replacement sorted in the next year, LE 11 will not support nVidia cards
FWIW, the un-powerful Intel CPU supports 10-bit HEVC today, and the future GBM/V4L2 graphics architecture that will replace X11 in LE.
