intel-dri and mesa-dri and vdpau in general

maggie · 2014-10-02 13:44:15

I updated today and allowed pacman to replace intel-dri with mesa-dri. There is an optdep called mesa-vdpau but I don't see anything about this on the wiki for intel graphics. Can someone set me straight? What drivers do I need for my in CPU graphics to work best?

xf86-video-intel is my xorg driver and required. I have some optional ones too including, intel-dri [replaced by mesa-dri], mesa-libgl (a dep I think), mesa-vdpau (I installed manually), and libva-intel-driver.

mesa-vdpau provides hardware video decoding for nouveau and radeon. There's nothing for intel in mesa-vdpau, so you can remove it. Intel uses vaapi for hardware decoding, libva-intel-driver provides that.

I recommend you to read the dedicated page on the wiki for intel graphics. All the informations you need are here. The only point to remember is, as you point out, that intel-dri is now included in mesa-dri.

Are you certain about this? It is listed as optional for mesa-dri.

According to the wiki, VDPAU is supported by GMA4500 and newer, and only if you replace the libva-intel-driver by the AUR libva-intel-driver-g45-h264 For older version of intel graphics, only VA-API is supported.

100% certain. Look at the contents of the mesa-vdpau package, nothing about intel in there, just nouveau, r600 and radeonsi.

Err, no. libva-intel-driver-g45-h264 is VAAPI and it's only for g45 chips, because the main libva-intel-driver driver doesn't have g45 support. VDPAU on intel is only available via a wrapper, libvdpau-va-gl.

My bad, didn't understand it correctly.

So,
for vdpau in intel gpu, we still need to use libvdpau-va-gl right?
It's just with me or libvdpau-va-gl is really buggy ?

I think that's why it is still AUR. NVM, it is in community, but perhaps has little effect on my hardware. VDPAU is a nvidia thing. Hard to believe that intel has been replaced entirely by just mesa. It is actually replacing all of the drivers ati, nouveau, intel, svga with mesa-dri. They can probably just squeeze them all in one dri file instead of several specific ones. Don't really need any powerful graphics functions when in console mode.

It's a wrapper, so not surprising it doesn't work perfectly. Its only use is with Flash anyway, for local file playback just use mpv, it has the best vaapi implementation.

Not particularity. While Nvidia came up with it, it was from the very beginning designed as a vendor-neutral thing. Mesa's VDPAU works well.

It is just one file. Well, almost. It's two files - one for classic mesa drivers, one for gallium drivers:

I got libvdpau-va-gl to to work, but vaapi works much better on my X220. I would call libvdpau-va-gl deceleration, not acceleration.

Using Intel HD graphics 3000 here.

Do you have https://www.archlinux.org/packages/?nam … tel-driver installed?

David Batson · 2014-10-15 16:01:53

After latest updates, vdpau working fine here. Not sluggish anymore. Also issue was solved with VLC crashing when opening some videos from file manager.

@Karol
Yes, I have had libva-intel-driver installed for sometime.
