There is supported for acceleration of parts of HEVC content on Raspberry Pi. Since the last couple of months, more H265 content is now playable on Raspberry Pi.
However both Raspberry Pi and ODroid devices cannot play back 10-bit HEVC properly, as the SoC does not support this completely.
If you want to play H265 you should try with the latest version of OSMC on a Raspberry Pi 3.
If you want to play 10-bit H265 you should consider a Vero device in the near future.
