Hi!

I have an IGP (RS880) with vdpau support, but can not use it because I have no GL_NV_vdpau_interop extension within OpenGL Sad

I'm already using the driver PPA from Oibaf

Where do I get the extensions from?

Your hw is not supported by kodi. As this ancient AMD gpu does not support GL Interop, no matter which mesa version you install.

You can use xbmc version 12.0 - which has an ancient hack to make vdpau decoding work on your hardware.

Ah, that table here was made before GL_NV_vdpau_interop was removed from mesa as described here.

So the freedesktop guys spent time implementing vdpau for rs600's uvd but it is unusuable if you want to have an osd Angry

Hey, I could get a HD5750 (RV840/Juniper/Evergreen) card- does this card support GL_NV_vdpau_interop?

TIA,
Caveman.

It can't do mpeg-2 in hardware ... get something sane :-) How about a Geforce GT 610?

(2015-07-07, 12:01)fritsch Wrote: [ -> ]It can't do mpeg-2 in hardware ... get something sane :-) How about a Geforce GT 610?

The only thing it does not do for MPEG2 is entropy decoding or am I wrong?

Nvidia? Never Tongue

If you run it via kodi / xbmc - it will segfault :-) that's what I tell you - if you can live with that segfault go ahead, hehe.

Where does that segfault come from?
Is it a bug in ffmpeg?

No - mpeg-2 is done in shaders only, no hw to do it, those are not thread safe -> buuuutz.

Have you seen this?
Also look at Comment 4.

So it seems to be possible to use vdpau shader based decoding without segfaulting.

Kodi's vdpau is multi threaded ... we decode and render in parallel. So if you want a shitty architecture: Decode -> Display -> Decode -> Display ... it will work, else not.

Here, read: http://people.freedesktop.org/~cbrill/dr...2013-11-02

it's not that we did not try everything ... ckoenig is main radeon dev in that regard, zgreg has implemented the Temporal shader deinterlacer. All the interop implementation was done, cause kodi stood up and said: hey we need something sane. The old pixmap hack does not scale - in fact E350 and so on, were much too slow to use the pixmap path ... kodi is OpenGL every comparison with desktop players leads to nowhere ... if you need to "share" / "interop" surface from vdpau to OpenGL InterOp is _the_ way to do it ... everything else sucks and especially old gpus won't have enough oomph to do it at all.

Seems that ckoenig gave up making MPEG2 decoding thread safe?
So it seems to be a bug in the vdpau state tracker?

Apart from that the IRC log is from 2013 and the awareness that the order of destroying the surface and the decoder must be respected is from 2014.

Or are these segfault sources independent from each other (so the order of destroying is not the problem here)?

Don't mix two issues.

VLC had a bug, in that linear chain .. they just reused something, which was destroyed in the driver / context whatever ... -> fixable, but has nothing to do with radeon's incapabilities in that way.

Our bug is not in the vdpau state tracker, cause if it was, no UVD hw could do mpeg-2 decoding, it's in the special implementation those radeon chips use, that do it in shaders ... and for now nobody cared to fix that in the driver.

Is the driver completely OS or is the UVD part a blob and only AMD could fix it?
IMHO DXVA has no problem with that.
