Linux Radeon OSS with vdpau (howto)
(2014-12-23, 15:57)fritsch Wrote: cat /etc/group |grep -i xbmc

Thanks for this information. But this is not the problem. I tested vdpauinfo with another user.

the kodi user has both: video and audio
Quote:audio:x:29:xbmc
video:x:44:xbmc
plugdev:x:46Confusedwi,xbmc
fuse:x:105:xbmc
xbmc:x:1001:
with xbmc vdpauinfo runs (see log)


//EDIT:
Now I had tested the driver with qvdpautest and it looks like mpeg-2 decoding is in shaders (see post 1 Mpeg-2 Crashes)
But If I disabled Mpeg-2 under Video Acceleratio it will crash, too. Only If i disable the whole vdpau it works. But than I have drop outs, if I play adiohd material (for example dts-hd streams)

the output is:

Your issue is 10.5 mesa version. It segfaults. Use what ubuntu provides 10.1.3 or 10.3.x.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

I downgrade mesa to 10.3.1. Now VDPAU is working.

I followed this guide to get a working media center with audio hd (dts-hd) but there are some drops in the audio playback, too.
Yeah, use a 3.16.x kernel and make sure to use the settings provide in the howto.

Mhnm I have kernel 3.16.7
When I set up "Adjust Refreshrate to match video" the audio is lost. Audio-HD only works with 60HZ on my machine.
Yeah, then it's clear that you will get drops. The 60hz bug is filed, I just linked it half a day ago. Nothing we can do for you.

Disable passthrough, use Video Clock and Resample Audio.

Okay, thank you Smile
The way I'm understanding this post, this has been merged into Kodi mainline as of 14.0?

So I can install Kodi in the traditional sense for my distro, or is using this method still advised?
You can install it wherever you want.

This is a minimal howto here, for "kodi only" users.

Depending on your distribution, you will need new enough libs, those are:

Mesa >= 10.1.3 - but not 10.5-devel (that segfaults) including mesa-vdpau-drivers
Linux Kernel >= 3.16.x but < 3.17 (as this has new power states which _might_ not work for you). On Ubuntu I suggest the 3.16.x via ubuntu mainline.

That's it.

Unity, kde, both use compositing, make vertical sync worse.

https://bugs.freedesktop.org/show_bug.cgi?id=86837 <- Here is a bugreport for the Mesa 10.5 segfault. Nice, it's f**cked up in the linker.

nice! thanks, @fritsch, for the link to the bug report.
i'll be sure to add my 2 cents after the holidays.

'tis a shame. it was working well at one point.

enjoy the holy-days.

btw - kernel 3.18.1 working fine for me on my AMD A6-6400K APU with Radeon™ HD Graphics
Linux Mint 18 LTS 64-bit - Kodi 17 Beta6
Odroid-C2 - Libreelec v7.90.009
Hi Fritsch,
I was wondering if the Kabini apu's were ok for temporal deinterlacing for 576i/1080i and lanczos upscaling for 576i?
I burn't my fingers earlier with a DN2820 nuc and don't want to make the same mistake againSmile
Kabini can do that, but it is limited to 2048x1152.

What about a chromebox? With Celeron 2955U?

Excellent, that's all I needed to know. Chromebox would be perfect, but for my needs the Kabini is cheaper.
Would the most basic Kabini do temporal and lanczos (2650) or would I need a 5150?
No idea - I only had a zotac version of an early kabini roughly a year ago. Perhaps someone else in here know.

How much does it cost?
