 |
|
Hi all,
I wonder why installing Kodi on ARM is hardmasked. It is such a mainstream use case and Kodi runs on almost all Raspberry distributions but Gentoo. Iiirc I had Kodi (or xbmc) running on my Raspberry B Gentoo install some years ago. However, I unmasked it an tried it. I always get error messages like "VFP single precision register expected -- `vldmia r0,{ q8-q11 }'". I know it is masked and I will not get support for it, but i wonder if anybody got it running anyway.
The main purpose of this Raspberry 3 will be a media player installation. And I'm sad because I have to go with LibreElec

Portage should show you the Gentoo maintainer's mask message if you try to emerge the package while it is masked. What did it show? What version of kodi did you try to emerge? I don't see any relevant masks for media-tv/kodi in the main tree as of my last sync.
It was probably masked because it does not build and the maintainer lacked the time, ability, or both, to fix it. |

forrestfunk81,
It builds for 64 bit Raspberry Pi 3. I have

in my binhost.
ARM things are not well tested, so don't be afraid to use testing packages.

Hi,
you can check if the ebuilds from my overlay are working with the rbp3.
I'm using an rbp2b and kodi is working like a charm.
https://github.com/dsiggi/odroidberry
The problem is, that you need some special options enabled when you build kodi for the rbp.
In the official ebuilds this options are not set.

Can you please submit a PR to https://github.com/gentoo/gentoo/ with the necessary changes to the Kodi ebuild and perhaps some information saying why the changes are necessary?
I'd must rather have all users use the same, working, maintained version from Gentoo that we can all improve together than having to resort to stumbling across overlays

I finally had some time to get Gentoo 64bit running on my RPi3 and Kodi compiles successfully. But the performance of Kodi is very bad.
If using the vc4-fkms-v3d driver, I get glitches and tearing in the Kodi UI (when switching through the menu).
If using the vc4-kms-v3d driver, the Kodi UI itself works flawless but the videos get stuck.
I spent most of the day searching information about RPi3 graphics and hardware decoding but I'm still confused. As far as I understood kernels > 4.19 have v4l2 m2m codec support, but this is not used by Kodi. But isn't Kodi using ffmpeg which supposedly supports m2m?
And furthermore there is something like mmal which also seems to do something like hardware video acceleration. And there is a USE flag for ffmpeg but I can not turn it on.
I'm not shure if it is possible to get Kodi run on a 64bit Gentoo with an acceptable performance for now.
My current setup: 64bit Kernel 5.1.0-rc6-v8+ compiled from https://github.com/raspberrypi/linux
