If I'm not mistaken I believe H.265 video doesn't playback on VLC in fullscreen mode either in Gentoo or Raspbian.

However, on Raspbian Kodi can playback H.265 in fullscreen.

Is it possible to install Kodi for Gentoo (ARM64) using emerge if not by compiling it?

Hi gilius,

apologies for the very slow reply - things have been extremely hectic at work lately, and I haven't had the same bandwidth for Gentoo stuff as normal ><

kodi v18 ships with the genpi64 image already, and is available on the binhost too. However I need to incorporate the patches for V4L2 into FFmpeg to allow v19 to be built and use the h/w acceleration. This is on my todo list.

See e.g. this post and this bug for pointers.

Best, sakaki
