[LibreELEC v8.0.0] RaspberryPi2 HEVC 10bit decoding

1st Official Post

    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)

    HEVC is already a big hurdle for a RPi. Making it also do 10bit making the CPU even more tired already.
    Get some proper hardware if you want to watch 10bit HEVC stuff, like an Odroid C2 or Wetek HUB.
