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

[bridgman]

I really think my requirement for fglrx is quite low. I just want hardware acceleration for video decoding so I can watch some 1080p video in linux environment. ATI/AMD, you really break my heart.

You'll get decode acceleration one way or another - might be open source drivers, might be fglrx.

You must be really lucky that it even began to decode. Which card did you use and what driver?

HD 3200 with catalyst 9.10

I'll have to find some more taxing clips, but in my experience so far, this has pretty impressive results. I've been trying some of the various h.264 clips (trying to find the highest frame size and bitrate ones I can) on http://www.h264info.com/clips.html

This isn't a comprehensive, or particularly scientific benchmark, but it gives an idea of the difference in processor (CPU) usage between Xv and XvBA. I'm using htop to monitor mplayer, btw.

Phenom II 810 (2.6GHz), MSI 790GX-G65 using onboard HD3300:


I am Legend 1080p (really 816p):
without XvBA: max 77% CPU
with XvBA: max 3% CPU


Coraline 1080p (from the link at the top of the page at Digital Digest)

without XvBA: spiked at 99% usage 102secs into the clip, mplayer complains system is too slow, but for the most part was 30-70%
with XvBA: %2-3

So far any of the others I've played back give the same results: no more than %3 usage. If anyone knows of a particularly strenuous clip I'd like to try it.

Cheers,
Jesse

lol, how come is it a "might be"?! I thought open source driver is the only option I have... Oh, my friend, don't give me hope...

realy its a good move to drop fglrx ....

i will tell you some points!

OpenCL/fglrx do not work on hd2000/HD3xxx openCL/radeon will work on HD3xxx

Viedeo acceleration/fglrx do not work on hd3xxx but will work on Radeon/Galium3D...

FGLRX will not have kernel mod settings ....



FGLRX is a Lame-Duck no one sould care abaut it..

Just wondering, why do you change your attitude so much about fglrx? Does it break your heart?~~~~~~~ LOL

Also hangs mplayer after a while here....

What I know is that there will be shader-based decode acceleration in the open source drivers. Don't assume any more than that.

Okay I just had my 3rd reboot due to a X Server lock up today , I'm done testing. F*ck UVD, I'll wait for the stable open source shader based solution.

I works a bit better for VC1 and some H264 L4.1 work too. But compared to vdpau it is definitely crap in the current state.
