 |
|
I put the latest (1.6.0) 64-bit image on an SD card and popped it into a Raspberry Pi 4B. My intent was to get Kodi running on it, and then copy the image to the Raspberry Pi 3B stuck behind my TV. However, I needed to enable MySQL and NFS support. I did that, let everything rebuild, fired up Kodi...and got stuttering video playback.
It looks like the raspberry-pi USE flag, which is recognized by the Kodi ebuild, is masked so that I can't enable it. Even on a Raspberry Pi. I played a video and tabbed over to a terminal window running top; I was getting somewhere around 250% or so CPU usage from Kodi, which would indicate it's doing software decoding. Ick.
I've tried adding use.mask and use.unmask directories to /etc/portage. I've tried setting -raspberry-pi and raspberry-pi in them. None of them seem to make a difference. There has to be something I'm doing wrong here, but what is it? |

use.{,un}mask goes in /etc/portage/profile/.
It looks like those flags are correctly unmasked on arm, but you're using arm64. |

Is that Sakakis image?
What version of kodi do you have?
Sakaki did a specially patched ffmpeg and Kodi to get hardware accelerated video decoding on the Pi.
That work was for old versions of Kodi and ffmpeg.
As far as I know, it was never upstreamed.

A bit of poking around turned up a 17.x ebuild in (IIRC) the genpi64 overlay...would that be the one? Maybe I should just roll the whole install back to that and just rebuild it with MySQL and NFS support, rather than try updating the whole system. |

salfter,
You should have a working ffmpeg and kodi in that image, as long as you use it as is.
Portage will choose newer versions in ::gentoo over older versions in Sakakis overlay.
The newer versions in the ::gentoo repo will not provide hardware decoding.
