I just checked Milhouse builds nad there is a build with added GPU acceleration to hevc:
LibreELEC Testbuilds for RaspberryPi (Kodi 18.0)
I´ll try this one
edit: seems to be big improvement to 8bit, but still no 10bit support:
LibreELEC Testbuilds for RaspberryPi (Kodi 18.0)
Hi,
In LibreELEC v7.x i could watch HEVC even with 10bit encoding.
In LibreELEC v8.x only 8bit works. At 10bit i have only audio.
Seems the support for 10bit hasn´t been added yet:
OpenELEC Testbuilds for RaspberryPi (Kodi 17.0)
