Looking for testers on Windows Vista/7 for DxVA2

[Steupz]

Tried to play the 2160 file and the driver crashed, no BSOD.

But an hour or so later, tried to play a simple youtube video and got a BSOD referencing this file atikmdag.sys

[Jean-Baptiste Kempf]

BSOD shouldn't happen, and I fear the issue is in the drivers... But if you could share logs or messages from before the crash, that would be cool.

Yes, as I said when I edited my post, it is Catalyst's fault. See this thread: http://forums.amd.com/game/messageview. ... erthread=y
If you still want the logs, can you tell me where they are stored?

vlc.exe --extraintf=logger --file-logging --logfile=vlc.log --logmode=text -vvv

[Chancer]

Being more precise, this is what happens:
The first time I open the file, Windows Aero "blinks" - goes off, then turns on again - and I get the message "Video drivers crashed but recovered".
After that, the playback continues, but the video screen is fully green.

If I run any video again (doesn't need to be 2160p, but I believe needs to be H264 to use acceleration, right?) it will crash and show the BSOD.

Here are the logs:

1. 1080p video playing fine: http://pastebin.com/cNSc4Hug
2. 2160p video (1st execution): http://pastebin.com/J3HNd9CC
3. 2160p video (2nd execution): http://pastebin.com/TLn5DW1r

The bug is in the ATI driver, I guess, but we'll see what we can do.

Hi,

I made a few tests with the Catalyst 10.7 and VLC 1.1.1 (I have a ATI Radeon HD5870 on Win 7 64 bits)

While I seems to works on my HD files, (the quality is ok and less ressources are needed) I have an example of SD file where I get a lot of macroblock (it becomes even unwatchable) the file in question is a MKV file where the video is encoded with x264, 25fps, 720*576 with an aspect ratio of 16/9 (which therefore give a displayed video of 1024*576)

When the GPU decoding is desactivated, no macroblocs, it plays fine like before.

edit : I have an I5 core 750 2.7 GHZ

How many ref frames on it ?

It is theorically DXVA compatible.
Please post a short sample of this file.

I'll try to post a sample on a website, (the original is 800 Mo) but I'm not really aware of this kind of manipulation, could you advise me a software in order to cut a portion of a MkV video file ?

Well in fact you could try this and in this order:

First remux your file with this version of MKVToolnix:
http://www.bunkus.org/videotools/mkvtoo ... -setup.exe (with installer)
or
http://www.bunkus.org/videotools/mkvtoo ... e-3.4.0.7z (without installer)

I know it's not the latest version but there are actually some issues and other default parameters in the latest version which may cause problems, so use v3.4.0.

Then either:
It works: perfect so it was a mux and/or container problem.
It does not work: still with MKVToolnix split a chunk of 20-30 MB of the file as a sample and upload it on some file sharing site like Megaupload or Rapidshare.

Of course check that the sample also has the issue. If it's not the case then cut a chunk of the original file with DGsplit and upload it. Read here about how to use DGsplit:

I have 2 PCs, one is desktop PC with E6850 CPU and ATI 5770, the other is netbook HP Mini311 (ION chipset). Both run on Win7 (desktop uses 64-bit, while netbook uses 32-bit) I use VLC 1.1.1 for both PCs. The graphics drivers used are the latest. (ATI uses CCC 10.7, ION uses 258.96)

I tested with Iron Man 2 mkv mentioned in previous posts, Avatar 1080p avi trailer, and video clips recorded from digital recorders from local digital broadcast (H.264 video and AC3 audio), and results were quite different.

For desktop PC, the VLC 1.1.1 with CCC 10.7 worked with DXVA for all clips. All clips were played smoothly. However for the HD clip recorded from digital broadcast became blocky occasionally.

For netbook, strange thing happened with GPU acceleration enabled. When AC was used, Iron Man 2, Avatar and SD clip recorded from digital broadcast played perfectly. But when battery was used, only some still frames were shown (however the sound played fine) and could not be decoded properly. However, the CPU loading remained low (around 50%) compared to software decoding. For software decoding, CPU loading would be 100% always, with choppy videos. But it was better than with GPU acceleration enabled.

I later found out that the cause of failure to decode was due to power options. I was using 'balanced' plan and discovered that for playing video, if AC plugged the setting was 'optimised for video' while for battery the setting was 'balanced'. The GPU acceleration only worked when the setting was 'optimised for video'. I consider that a bug because even WMP could play the Iron Man 2 and Avatar trailers well with DXVA enabled using battery.

Would VLC developer look into my problem and fix in next release?

Ok, following your instruction I remuked the file and the result is still the same.

So I created a split of the file in 30 MB portions.

you can find one sample to dowload here : http://eltouco.chez.com/Movie-DXVA-macroblocks.mkv

hope this helps

chpyeung: power saving options also cause sync issues for VLC.

I tested that file, the same thing happens here. Plays fine with GPU disabled, crappy when enabled.

By the way, I tried to set "Video quality post-processing level" to any value different of 6, but VLC won't save it.


At last, I'm looking after some Level 5.1 videos for testing, but I can't find any. Do you know where there are some?

[Dario!]

Mee too when i try to play that video with the GPU accelleration enbled i see many "bad blocks". I have an ati HD4850 with 10.7 driver on Windows 7 32bit
EDIT: I tried to play two different 1080p video (.mkv h264 codification), with GPU decodification enabled, both the video didn't start to play: VLC didn't crash, but the video didn't start.

[Steupz]

Running a Radeon 4200 card on Windows 7 Home Premium 64 bit.
I just uninstalled the new Catalyst drivers and I recommend the same to everyone else. Just had my third blue screen and it seems to be happening to others too.

I'll wait for a better driver set to properly test the DxVA2

We don't need testers to test if this functionnality works (it does), we need bug-reports now
