AMD's UVD2-based XvBA Finally Does Something On Linux

[Kano]

Why don't you use 0.5.1? In order to use 0.4.x you would need older mplayer snapshots.

@Kano

I'll spell it out for you: IT DOES NOT WORK WITH 0.5.1!

Check the quoted output. Yes, really, just read it and it will all be clear.

That we might need older mplayer snapshots is constructive. What's missing there is which ones would work in combination with it. The last versions are alpha at best I'd say, so the previous ones are probably worse. For all I know we'd need an older version of libva too. Three packages, all with several different versions. That's a lot of combinations to try out...

[Kano]

Basically it is useless to try all those things. If you want something working now you just buy something from another vendor

ok, I've fixed the manifests and will probably add hwdecode demos in overlay soon

[Kano]

It would only work with the -glx option.

thanks, with glx vaapi_x264 and vaapi_vc1 do work just fine, but mplayer still crashes with

[VD_FFMPEG] Trying pixfmt=0.
Unsupported PixelFormat -1

[RemcoL]

I removed all of it, then installed the drivers, libva (and libva-dev) and xvba-video again.

Seems like I made a typo when linking libAMDXvBA.cap in /usr/lib the last time, since now vainfo works. hwdecode-demos always come back with "checking for XvBA... no". Everything else in the configure goes through fine.

When checking out the configure script I noticed these two lines:
#include <amdpcom.h>
#include <amdxvba.h>

Those files are nowhere to be found on my system, nor do I know if they're actually needed.

Compiling mplayer-vaapi now also goes through properly.

mplayer -vo vaapi:gl -va vaapi <file>:

real 2m20.468s
user 0m4.500s
sys 0m2.952s

mplayer -vo gl:yuv=2:rectangle=2 <file>:

real 2m20.454s
user 1m0.936s
sys 0m0.752s

So success!

ATI wants to hide those files it seems. Classified, high security risk, ATI will be going bankrupt then those files would be officially available.

[SP8472]

BTW, I never really tested the 64-bit binaries, so it does interest me to know whether they work or not.

As I said earlier:

Basically works, but the colors of the decoded videos look slightly wrong.

[Kano]

I had wrong colors with one movie too, others worked.
