ArtVandelae Wrote:Again, the videos currently giving the DXVA decoder problems are not out-of-spec clips that push decoders to their limits, but standard blu-ray compliant clips that play on everything including a Blu-Ray player, a Broadcom card, the PS3/360 and any other consumer devices that do hardware decoding. Trying to play a video with too many reference frames on an ATI card (like the Quantum of Solace trailer) just gives you garbled, yet visible, video, not the solid green screen that many clips show in XBMC on both Nvidia and ATI cards.
Well then , for the clips you are refering to (the ones with the all - green screen) , it's up to the xbmc-team to figure it out. As far as for the clips with green artifacts , this is ati's problem . To my personal experience , i have only seen clips with green artifacts related to ati's limitation . I haven't seen the all - green screen you are refering to . And by the way , catalyst 10.1 doesn't seem to solve the limitation - problem

Are there any ATI settings we should be looking at? I am running the 10.1 Catalyst drivers and am seeing the green pixels on certain files.

Unfortunately not . There is absolutely nothing that can be done . Not a registry hack , not a change in the catalyst control center not anything else. This limitation is imprinted in the drivers . I assume that some guys , like the ones that were working in ati's modded drivers , like omega drivers , could do something about it . But then again , most of these projects died months ago .
The only thing i assume we have to do , is to wait.. .. Or to buy a nvidia card!

Interesting observation about the ATI Driver producing the Green Screens.
With my ATI HD 4350 based HTPC, XBMC produces a Green Screen with any 1080p DXVA enabled material.
On the other hand with the same gfx card, The Boxee Beta plays back everything 1080p just fine with DXVA enabled, including direct ripped Blu-ray streams (str)
My other system which has a nVidia GTX 9800, both xbmc and Boxee play just fine though xbmc exhibits the green screen for a few seconds into a movie.

Yeah, I've had my 4670 for over a year now and this is the first time in any DXVA/2 application that I've seen any green whatsoever (other than a flash when the display is initialized).
That being said, I'm probably going to move to an nVidia card when I replace this one anyways.
Screens on nVidia too - Smeezy101 - 2010-02-03 01:13

I'm getting green screens on both of my nVidia based 'puters - one is a Zotac Ionitx, the other a GeForce 9500 GT. Seems to happen only with MKV's at this point. M2TS and DVD VOB's play fine. This occurs when DXVA is set in video settings. On automatic, it doesn't happen...
EDIT - title should say Green Screens on nVidia too

Tested this on my game/work pc, quad 6600 ati 4890 no problem at all, win7 64bit
Tested on my htpc E8400 nvida 9400GT on-board gfx, spdif out no problem at all, win7 32bit
Subs embedded in mkv working and browsed sub/srt subtitles in rar/zip archives working.
At this point everything i tested tonight was working
Thax a lot

I played several 1080p and 720p h264 videos without any issue. But when I just now tried to play the lastest video from the TED video podcast  I had an all green screen instead of the actual video. Video is reported as
D(VIDEO: H264, YUV420P, 432x240 [PAR 1:1 DAR 9:5], 364 KB/S)
Since this is a video from a freely available podcast it should make it a bit easier for the developers to test the issue.
Debug log is available here: http://pastebin.com/m10260785
My graphics card is a XFX GeForce GTX 260 Black Edition (216 cores) and I am running driver 196.21 on Windows 7 Profession x64.
