+--- Thread: VDPAU API for Linux released by NVIDIA today - GPU hardware accelerated video decoder (/showthread.php?tid=40362)
- pete-woods - 2009-02-20
I was just wondering what you guy's view on on VA-API was. I just read an article on Phoronix saying that someone's built an NVidia back-end for VA-API using VDPAU. (Obviously) Intel GPUs are supported by this API too. I figure if hell freezes over one day and ATi release support for GPU assisted video decode under Linux then someone could write a back-end using whatever API ATi has used.
My thought was that it might save you effort in the long run if you want to support as many GPU platforms as possible. I don't know if there'd be a performance penalty for using a wrapped API, or if I should be saying this to the ffmpeg guys instead.

I am still looking for some input from the master
I posted this in the linux end user section, I wonder if you can replay to the belowmany thanks
motd2k
first thanks a LOT for all the dedicated time and the great features you added to XBMC.
Having a fast CPU, hardware acceleration wasn't on top of my wishlist, however I really really really (you can tell how excited I am, can't you ) wanted to see extra filters in the dvdplayer to smoothen and denoise the picture and I just saw your bug
http://trac.xbmc.org/changeset/17795
and noticed that you indeed implemented this feature.
My questions for you and anybody who used these filters
1) how is the picture quality on a large screen tv? I love XBMC but my only concern was the picture quality and I have a 2 page thread http://forum.xbmc.org/showthread.php?tid=45425
explaining what I was experiencing with 1080p mkv playback and I highly believe that these filters will take care of these dancing pixels in the background, am I wrong?
2) I have live version installed on my machine, which is hardy OS version, I just want to double check that if I check out the vdapu branch I can just compile and run it on LIVE, right?
3) these filters are flawless? how do they perform?can I tweak them from the GUI?
update
// FYI I just looked at your code check in and I see that the slider has been added, but noticed that you are not writing the settings to the guisettings.xml file, so I guess the filters are per movie? and can't make them default
Thanks again

motd2k I just finished installing your latest rev, 17916
1) vpau works perfectly on the couple MKVs i tested
2) picture looks great, it fixed 90% of the problem i was experiencing before, looks very nice
3) the only issue is that "all" the filters are not working, It looks like they are broken, nothing is changing when increasing/decreasing
- brightness
- contrast
- (vdpau) Noise Reduction
- (VDPAU) Sharpness
- (VDPAU) Inverse Telecline
Am I missing something before I dig into the code which will take me some time to figure..
Thanks

It does not happen every single time but in the large majority attempts to use the OSD during play via VDPAU, I simply get a frozen XBMC which I then have to kill by issuing ctrl-c on the console I have launched it.
When I have it running in fullscreen, it occasionally freezes X completely, so I need ctrl-alt-backspace to get it to restart X.
Does anyone else see this?
This is with R17955 and nvidia 180.29 drivers on Intrepid, movies play just fine in mplayer-vdpau.

17955 isnt a xbmc-vdpau revision, my last commit was 17938! really need log files or we cant help!

As a cheap card for testing, would this work:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814127367
It does have G98 core, is the 256MB enough?
Thanks.

Pay $5 more - cheapskate!
