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

[tetsuo55]

I have tested DXVA vs. CPU decoding on several machines (some laptops and some desktops) with a tool to measure power consumption and the results definitively show that in all cases DXVA uses considerably less power. Aside from the power savings, which is mainly helpful to laptop users, it frees up the CPU so you can watch a movie while encoding or something like that.

Or use the left-over power for all kinds of post-processing on both video and audio

ffdshow video PP w/ DXVA is a no no....CUDA OTOH :D

Forgot about that part.
Amd on mobo graphic cards can get cpu assist with the post processing(after DXVA), but you need high TPD cpu for that so its useless.

[tetsuox]

CUDA decoder won't be power efficient since it uses all the shader processors on a GPU compared to the dedicated VP2/VP3 unit on Geforce8/9/200 GPUs which uses very little power.

You can use CUDA to access the VP engine on the GPU as well.

hummm, some words seem to be missing I think..care to rephrase?

The MPC-HC Video decoder must be connected directly to the renderer. That means no intermediate filters such as [..] ffdshow can be inserted between the decoder and the video renderer.

I was merely pointing out that you can use ffdshow video PP w/ CUDA, so the GPU does the decoding and your CPU is fully available for LSF ss2.0 craziness in ffdshow :D

I understand what you meant.

I will rephrase:
The ATI HD3200 (a onboard videocard) has little or no post-processing abilities(standalone cards do have them)

When you put a phenom or higher CPU into this motherboard, the phenom will do the post-processing.

This post-processing is done after DXVA decoding and is controled with the sliders in the ATI display driver window.

However there is no difference between this kind of post-processing and dedicated videocard post-processing.
Both are useless when compared to ffdshow.

[leeperry]

ah, you mean the HD3200 IGP :)
yeah sure, contrast/brightness/hue settings...a far cry from LSF in ffdshow ;)

Don't forget softening/sharpening and denoising.

Still a far cry from LSF

sharpening/denoising on DXVA? you actually saw it working ?
I heard these sliders only worked on Overlay/VMR/EVR with UVD 2.2 graphic cards(HD4xxx)....apparently they don't have any effect with HD3xxx card in PDVD8 for instance.

Interresting..

I have all post-processing features disabled using a registry key so i have no idea if ATI's claims are true with regards to those working on DXVA

no UVD 2.2, no dice :o

[Kurtnoise]

it seems that multichannel flac streams (embedded in containers or not) are not decoded within the internal filter, correct ? missing feature or bug ?

I'd like to do this too. pls tell me what the key is.

I like dxva -- when it works. I don't need to do PP on HD content. My problem is my video is too dark, almost as if there's a double 16,235->0,255 expansion that crushes black and can't be compensated by adjusting brightness..

there's plenty of PS scripts for levels conversions ;)

[STaRGaZeR]

UVD has nothing to do with this. I've been using them since my old HD3870. You only have to output NV12 as always that you want something from the ATI drivers like your famous chroma upsampling.

[flanger216]

ATI's denoise and edge-enhancement filters actually always work, regardless of using DXVA, and on anything from HD36xx and up (I think). You just have to feed it NV12. The denoise filter is fairly decent... it only kicks in on interlaced material (I wish this was configurable, but it does make some sense on their part), and it looks almost comparable to Denoise3D in FFDshow. You just have to turn it way, way down from the default settings.

Their edge-enhancement filter is wretched, though. Ay caramba!

it would appear that the sharpening slider has no effect in PDVD7/8 w/ DXVA enabled on HD3650/3850(UVD2), but would work perfectly fine w/ HD4xxx serie(UVD2.2).

it seems that PDVD outputs in VMR9 Renderless, dunno about the colorspace though..

That's because at least in the HD3870 the sliders only work with SD video. With the HD4870 it works with SD and HD. But again this has nothing to do with UVD.

This is with EVR Custom and in Vista, dunno about other configurations.

i can't find one for 0..255->16..235 could you point me to one please?

[73ChargerFan]

there's plenty of PS scripts for levels conversions ;)But shaders don't work with all renderers.

How about a debug path, which checks the min/max of the video levels and shows it in the filters in/out properties pages?

[clsid]

Use the Levels filter of ffdshow if you want to see that.

[leeperry]

Seb.26 has made tons of scripts, use google translation :
http://www.homecinema-fr.com/forum/./viewtopic.php?f=1195&t=29814317

he would even make a custom script for what you need if you ask nicely :D

but your problem seems odd, if you have an nvidia card try to change the levels for video renderers in the drivers...or simply calibrate your display to convert 0-255 to 16-235 internally? at least the windows desktop/digital pictures will also be properly calibrated.

this script would be doing 16-235 > 0-255, mess with the figures until it matches maybe? using a THX calibration disc for instance :

sampler s0 : register(s0);
float4 p0 : register(c0);
float4 p1 : register(c1);

#define width (p0[0])
#define height (p0[1])
#define counter (p0[2])
#define clock (p0[3])
#define one_over_width (p1[0])
#define one_over_height (p1[1])

#define PI acos(-1)

#define Const_1 (16.0/255.0)
#define Const_2 (255.0/219.0)

float4 main(float2 tex : TEXCOORD0) : COLOR
{
return( ( tex2D( s0, tex ) - Const_1 ) * Const_2 );
}

[tetsuo55]

I just re-tested my display

Strange result:

-Desktop shows 0-255! (actually 5-255)
-FFdshow with rgb conversion enabled(doesn't matter if i use full or limited range) results in 16-235

all my test samples pass!!!
I was unable to test DXVA.

Remember my display is limited to 16-235 according to the manual....

[marc99]

I tested Microsoft DTV-DVD Video Decoder delivered with Windows 7. They support DXVA and looks like, he dosen't have 11+ references frame bug. They have GUID H264 {34363248-0000-0010-8000-00AA00389B71} and h264 {34363268-0000-0010-8000-00AA00389B71}. But doesn’t have AVC1 {31435641-0000-0010-8000-00AA00389B71}. Is it possible to make splitter enumerate (add Type 2) GUID AVC1 to H264? mp4 splitter uses both avc1 and AVC1, add H264.

[73ChargerFan]

Use the Levels filter of ffdshow if you want to see that.Can I use ffdshow with the built-in dxva decoders?

[Spec-Chum]

Hi, I'd like to start by saying fantastic work to the Devs, I've been using MPC-HC exclusively for many months now, and I think it's incredible.

Anyway, on to my n00b questions...

Is there any way I can resize before running the shaders? I currently use ffdshow to resize to desktop resolution, then use the "Sharpen" filter in MPC-HC, which whilst I do like the output, I'd rather do it all on the GPU, and sharpening before a resize is a no no, quality wise.

Also, VC-1 playback from evo is very juddery when using WMVideo DMO, which goes away if I use ffdshow to decode, but ffdshow speeds up every time after about 3 or so minutes, and completely loses sync (using both WMVideo DMO and libacvcodec). Any known fix for this? This is with Haali splitter BTW, as the internal splitter doesn't even open the file (well, it does, but it goes into audio only mode). I've been searching for days, I know (well, educated guess) it's related to pulldown, because demuxed evo files work fine.

I've got quite a large library of HD-DVD's so demuxing them all is not feasable :(

Any help appreciated.

Spec

[Hypernova]

I just tired Microsoft DTV-DVD Video Decoder too. I can only get one file to work (x264 in .avi. I don't really know how to give you more useful information about the file). I read from an article and it seems like the decoder can use the partial GPU mode as well. Requesting a feature about using this maybe strange now, but I do think it can be useful in the future. Just my two cents.

BTW, big thanks to all the developers. This is a really great player.

I found an issue with some mpeg files. File duration is not displayed correctly:

[Amour]

* Perfect support (including menu's. etc..) of the top 10 media container formats(excluding those used on disc based media) using the internal splitter

How do you plan to set the top 10 media container list?
Something like:
1) .wmv
2) .mov
3) .rm
4) .flv
Or something like:
1) .mp3
2) .ogg
3) .mid
4) .wav
Or probably like:
1) .avi
2) .mkv
3) .mp4
4) .ogm
It will be hard to make a selection of the 10 "top" formats, because there is many, and we can use many criteria to compare them (commercial use, all-time use, p2p use, newest use).

and mp4 menus style...:D
What is an mp4 menu style?
Anybody have a screen capture of it?

Also please don't waste time on CD Audio and DVD Audio, Foobar2000 is clearly superior for audio playback. MPC is a video player first and foremost. Don't be a jack of all trades, master of none. VideoCD is dead, no one cares about that.
I disagree on that. People use ffdshow because it is a "jack or all trades". People don't want to have a different software for everything. I don't know what lacks MPC, but if there is no support for CD Audio, DVD Audio and VideoCD, please add it in the future.


Why does everything have to be done by the internal splitters and decoders? If there's a perfect, free and well supported splitter/decoder out there for a specific format, why putting the burdon on the MPC HC developers to reinvent the wheel?
We could offer on SourceForge a combined download: latest stable build of MPC-HC + latest stable build of ffdshow. I know there are already "packs" for this job like CCCP, but here it would be available as an "official" bundle.

[ADude]

I also would like to see DVD-Audio support.

Also, I tried playing an MKV with a 24-bit surround FLAC using the Open -> Dub and I just get silence. The filter configuration just gives me settings for AC3 and DTS.

[73ChargerFan]

I'd like using a dub soundtrack to disable those in a .m2ts stream.

If you have nVidia cards, you can do ffdshow desktop resize and then do sharpening with nVidia control panel. Doable with ATI cards too but lesser combinations of colorspaces etc.

I meant "Sharpen Shader", sorry. Doing it your way is still using ffdshow to resize, I just want the PS BiCubic resize to happen before any other shaders, is this possible? Is the resize available as a standalone PS?

Also, anyone know a fix for the VC-1 in evo issue?

This would be changing the resolution, which is not possible (yet) via a shader...

(And neither is doing the resizing in two passes, unless you want to make two shaders out of it...)

Ah, makes sense. So the resize can only be done in the [custom] presenter, not as a standalone?

Thanks for the clarification :)

Actually, the resize and applying shaders in general both can only be done with a custom presenter, as earlier filters either have no image on the graphics card to begin with or don't know where to look for it there.

IINM, nVidia/ATI edge-sharpen features is done after the PS bicubic resize has been applied.

Even with the last version of MPc-HC 1.2.972.0 MLP soundtrack doesn't work, is-it normal because in the log file there is "Support for MLP audio stream"?

In Ghost in the shell blu-ray when i want to select mlp soundtrack, I d'ont have sound. I have sound just with lpcm soundtrack.

To have sound with mlp soundtrack i must use ffdshow

i give you 30 seconds of the video where mlpc soundtrack doesn't work (ghost in the schell)

The change does say something about possible problems with non 16bit streams, but this should be related to LPCM not MLP

Is it possible to revert the value you changed in src/apps/mplayerc/EVRAllocatorPresenter.cpp in rev930 (10000000I64 to 20000000I64) back to 10000000I64 until Beliyaal fixes are done? In the recent builds the jitter calculation and consecuently the graph are way off.

I can't think of a technical reason - MPC's resizers and shaders are just some shader programs that transform one texture into another, it's up to MPC to decide in which order to run them.

It's just the way it's currently implemented in MPC-HC. A possible UI solution to decide where to resize would be to change the "Combine..." dialog to allow placing the resizer (once) somewhere in the list.

Just an idea, though.

np: Flying Lotus - Riot (Los Angeles)

Now if only there was some noise texture one could use in a shader to add some slight hi-res noise after resizing... *hint hint*
