Media Player Classic Home Cinema (MPC-HC) - DXVA!

[Casimir666]

Whouaaa so many messages about subtitles !

@pdanpdan
DXVA didn't works when there is filters between video decoder and renderer, so ffdshow or DirectVobSub are prohibited if you wan't to use hardware acceleration. Can you PM me a link with a sample that crash mpc?


@donaldtone
Not 100% sure, but I think VMR7 required at least a video card compatible with DirectX 7, and VMR9 at least DirectX9.

Casimir, can you add to

File->Open File... -> Dub -> Browse

the .AC3, .DTS, .EAC3, .Flac extensions in the "Objects of type" filter of the dialog box?

and

File->Open File... -> Open -> Browse

the .Avs extension in the "Objects of type" filter of the dialog box?

Thanks

On my 3870, DXVA is working GREAT with everything but 1080p files with this. 1080p files just show a green screen. What are the odds of that ever working, or is it just because of the way the files are encoded? (I remember reading something about level 4.1 being the max or something?)

Also, what are the odds that just the filters will be released alone (hopefully in x64 form) so that we can use DXVA on other programs (I mainly want to use it in Media Center.)

[leeperry]

anyone manages to get rock solid 24.000 FPS ?

I got Reclock running with EVR on XP SP2, resampling 23.976@24 in 48.000 Hz

it's usually fine for 10/15 mins, then it starts oscillating between 23.99x/24.00x and starts dropping frames

If only I had an idea about wtf is up...

I don't think the problem is the resolution (i have some 1080p video that works). Some H264 with 5.1 level works too, but other display black or green screen. I haven't find a solution yet to detect such files and switch automaticly to software mode

I thought that it was determed down in the AVC forum that it was the ref_num_size block, and if it exceeded a certain threshold that hardware acceleration broke

If you perform the following checks on the header of the file you will know if the file is DXVA able or not

First check if the SAR is okay:
"only allowed are 1:1/4:3/5:4/16:9"

If SAR is okay, then check the resolution and ref frames with the following calculation:

For resolutions higher than 720x576
mod16 width X mod16 height X ref frames <= 8355840

For resolutions equal or lower than 720x576
mod16 width X mod16 height X ref frames <= 4561920

If SAR is not okay, default to software mode
If width or height is not mod16 default to software mode
If calculated values are higher than the maximum number default to software mode
In other cases enable DXVA

Ok this is the easiest things to check.

Hum... all broken files i had respect your rule :
- Sample1 : 640*480*8 = 2457600 < 4561920
- Sample2 : 720*416*6 = 1797120 < 4561920

I have read part of the thread, the incompatility rules seems not so clear

[tetsuo55]

Could you post the avinaptic output of these samples?

(the other fail reasons are not so easy to detect)

By the way, how did you compute the limit value 8355840, because i have also seen 8294400 (1920*1080*4) in your thread?

Oups i'm stupid it's 1920x1088*4

[tetsuo55]

That limit is based on the real HD resolution 1920x1088

Well from your problem descriptions its obvious that DXVA is enabled, otherwise you would not be seeing the crash/green screen

Now as too why the files do not work, there are 2 issues i can see here.

Issue 1, mkv problems, you can try remuxing the video's with the latest version of mkvmerge.

Issue 2, Those files where made with old to very old versions of x264, it is actually known that these older versions contain a bug that break DXVA.

(Issue 3, the level is wrong, but this does not matter for your player, if you change the level to 3.1 you can test them with the cyberlink decoder)



This is not something you can easily test the file for, maybe its a good idea to report these non working files in the dxva problem thread, and see what the others have to say about it.

I say we ignore these for now, as a new encode with the latest version of x264 should work(as proven in the dxva problem thread)

The subtitles are included in the MKV files, not external.

I had the same problem too with subtitles in MKV. I have to delete the key "HKEY_CURRENT_USER\Software\Gabest\Media Player Classic" in the registry, reconfigure MPC HC and then, I have subtitles.

Hi,
on my machine with r396 mpc hc some files do not work with DXVA which work fine with cyberlink h264 decoder in DXVA mode. These are mainly 25fps h264 sky captures (these show black and white / half screen garbled in MPC HC) and some files show just green/black screen. So it seems apart from level 4.1 compliance there is something cyblerlink does, which sets up the ATI drivers to properly do DXVA acceleration - maybe it sets some additional parameters.
One other thing: Is there a way to make m2ts or evo files show up in the file requesters by default - i always have to set it to "show all files"... is this configurable?

What is the way of getting subtitles and still have DXVA?

use a renderer that supports subtitles
like
vrm9 renderless and, haali, and evr

[CruNcher]

Haalis renderer supports DXVA now???

Most probably a MBAFF Decoding problem how it sounds seems this kind of decoding has to be specialy triggered in Nvidias and ATis APIs to work in DXVA, especialy in combination with their Motion Adaptive Deinterlacing Stuff.

Is it interlaced video? I think there is a problem with such video at the moment.

from what i've read it appears to, but I might be wrong, I kinda suck with renderers
