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

[n0nsense]

I did, and then you have to remember to remove your own stuff when official arrives Otherwise you end-up with to much junk and it takes time to fix it I guess i'm sticking with Gentoo mainly because I like it's performance, customability and the "rolling, always latest and greatest" way of updates but i'm almost not experimenting with it.

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.

Try full BR video, better something VC-1.
If your system can handle it, then we have very good news

if you have any funktion on the uvd1 in use you can revers the copyprotection.

why there are no specs for the uvd2 unit?? its only because if they push out specs they lost@copyprotektion

How to crack the copyprotection is well known for quite a while now ( and in reality it isn't cracking it but using a known good key to decrypt the protection) and doesn't require UVD at all to show how it is done.

https://help.ubuntu.com/community/Re...BluRayAndHDDVD

When a new key is required, a bluray player does not "decrypt" the new key on it's own. It requests a new key online that updates the players firmware with the new key.

So how well does this work together with compiz/kwin desktop-effects?
And what about tearing, with and without compositing?

I'd love to but I have no BluRay clips or discs here. Any (legal ) links? I'm searching as we speak, but if you know of any I'd love to give it a shot.

As UVD provides full bitstream acceleration you should never see high CPU load.

@Qaridarium
The open source approach will probably not use the video decoding hardware, but shaders, and this won't be as efficient as bitstream-level acceleration -- not all decoding steps can be offloaded to hardware this way.

I was in the same boat with my old Geforce 8800GTS G80 not supporting VDPAU.

From what I know there were major internal architectural changes between UVD -> UVD2, which made it a lot easier to port (code wise, and hardware wise)

Yeah. Me, as a owner of a HD3650, I feel betrayed/dumped. Are UVD1 or UVD+ so different from the UVD2 that a unified or parallel driver is too much effort to implement?

R63x is not that old!!! They're very similar to R700... why in the world are they loosing feature support?
So disappointed

If they hope me upgrading to R4xxx or 5xxx, well, this time I'm giving my money to nVidia. Sorry

Actually.....the 7xx was very very different compared to the 6xx asics.

The major difference between uvd, and uvd2 is the mpeg decode part.
