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

[ghostonline]

I'm using mpc-hc 1.1.0.0 on WinXP with a HD3850 card. I have four videos in H.264 which can be played using DXVA - their size is 1280×720 at most. (mpc-hc reports "H.264 bitstream decoder, no FGT")

But I also have one which is 1920×1080 big and no matter what I try mpc-hc just says "Not using DXVA". Is this the expected behaviour?


H.264 =/= DXVA will always work.

if the file is not encoded to match the dxva specification, it will NOT work.




There's no WMV DXVA support yet; read the first page. But you can try H.264 here:

I have a Nvidia 9600 GT + WinXP SP2, but no luck, as you can see here (http://forum.doom9.org/showthread.php?p=1123650#post1123650). Let's see what happens with your 8800 GT. :)

I tried 720p one. these files do work with dxva, but need little trick..
mpc-hc 32bit, xp32bit/vista64bit, 9800gx2 (based on the same core as 9600gt, 9800gtx, 8800gt, and 8800gts 512MB version)
rename *.MOV to something else. example: *.mp4 or avi or mkv

mpc output: vmr9 windowed/renderless for xp32bit, evr/evr custom for vista64bit

mpc-hc internal dxva decoder: only partial of video will display, but it does work.
powerdvd h264 decoder: video works fine.

Well, if you can't see the whole video using the internal MPC DXVA decoder, so I think it's not necessary to rename the video extension. Also, PWDVD decoder works fine here even with the correct video extension.

well, mpc internal one does work on some other h264 files, just not the one you mentioned.


pwdvd decoder works fine for you without rename it, that's good. i can't get it work without change it to mp4 or something else.

I see. Is there a way to see what is wrong with the encoding?

[airwin]

Request for enhancement:

Direct3D Fullscreen mode to take effect only if actually fullscreen mode is requested via the fullscreen keyboard command.

Or the option checkbox to be removed entirely and a new keyboard command "Fullscreen (Direct3D)" created. This could be bound to Shift-Enter by default.

when I use gcc for mpcvideo compilation,I get this link error~~

[Coren]

How are you encoding?

http://www.avsforum.com/avs-vb/showthread.php?t=972503

That's very interesting, thanks for the link. So I guess that those files that don't work with DXVA or those that look all blocky were just not encoded according to specifications.

Maybe a suggestion: isn't it possible to make MPC automatically detect whether or not the file is encoded correctly so it switches off DXVA/switches to an external filter to avoid those blocky artifacts?
Of course the real solution is to get everyone to use the correct settings, but it'd at least allow people to play back their older files without having to switch to another player...

[leeperry]

often when I play WMV files and I close MPC HC, mplayerc.exe remains in memory.....and I have to kill it manually in order to be able to open a new file :(

I've got the latest WMV "wmfdist11.exe" official codec pack installed on XP SP2...and it's quite random.

could you offer an option to kill any "mplayer*.exe" when you open a new player ?

or make sure that it kills its own process when you close it ?

it only happens with WMV files, and I've tried to decode WMV files with ffdshow, problem remains.

some deadlock with the WMV splitter ? :eek:

TIA,

There's no WMV DXVA support yet; read the first page.

Windows XP/Vista has built in DXVA support for wmv9, use WMV PowerToy (http://www.citizeninsomniac.com/WMV/)to enable it, the rest of the procedure is about the same as the one with h264, use evr/evr custom/vmr9 renderers and the wmv decoders v11 without any filters in between.

[terence_13]

@drevil_xxl
In r495 mplayer.rc this change was made:

IDS_VDF_IDCT_SKAL "XVID" -->IDS_VDF_IDCT_XVID "XVID"

If I am not mistaken, the same change should be mad to MPCVideoDecFilter.rc? This at least helped me to compile the standalone filter.

Best,

Right. I was talking about MPC HC internal decoders support. But thanks for the additional information. ;)

BTW, I downloaded the WMV PowerToy and can't notice any performance improvement setting DXVA on or off. Tested with these videos:

http://download.nvidia.com/downloads/nZone/videos/PureVideo_1080p.wmv
http://us.download.nvidia.com/downloads/videos/GF8800Demoreel_High_8000.wmv
http://us.download.nvidia.com/downloads/nZone/videos/nzm_Cascades_tech.wmv

I have WMP11 decoders installed.

EDITED: forget it. My mistake.

You could try WMV/WMA Parser:

[rica]

Hi guys,
When i open an h264 ts stream with MPC-HC, program closes itself. Also i tried with GrapEdit using standalone MPC Video Decoder; nothing has changed.
Any comment would be appreciated.
(I use EVR on Vista32)

[DeepBeepMeep]

I have noticed that the 'Next Audio' key won't works with a m2ts files with multiples tracks but will work with the same file remuxed to a mkv file while using the Haali filter as demuxer.

It is a shame since bluray are m2ts files and to obtain a proper playback one must enable Exclusive full screen which doesn't give any access the Haali filter options.

Any hope for a fix? Many thanks in advance

[leeperry]

cool, thanks for the suggestion.

actually the problem with MPC HC remaining stuck in memory comes from the luma sharpen of my spline resize in ffdshow.

if I disable it, no more hanging with WMV and 1080p MKV files.

I've just tried to force this parser, and it was hanging again :eek:

I took it off, and it's fine :)

Hi,

I need some help with playing back quicktime-files without quicktime-player/itunes.
Currently playing my files with Media Player Classis 6.4.9.1 (normal/unpatched) + ffdshow-rev1928_20080410_xxl.exe

The problem is: mov-files are not being played by this combo and I would like to know how to get this fixed ? MP4-Files are being playing just fine. Do I need to change something in the settings or is this combination not able to play these files ?

[clsid]

That combo should work just fine. Enable the internal MP4/MOV splitter and the proper audio/video formats in ffdshow.

You should elaborate about "it does not work". Do you get an error, does it crash, does it play improperly?

[machser]

That combo should work just fine. Enable the internal MP4/MOV splitter and the proper audio/video formats in ffdshow.

That just helped! I'll check this the next time first, THANK YOU, you made my day! :thanks:

If you have time, I would need an explanation of the proper settings in ffdshow you meant above. Any time free for that ?

I chose to add support for VfW only, while installation of ffdshow, was it the right choice for my system/me, how to determine this for my usage (using VirtualDub and AviDemux, too) ? Can't find a manual or documentation for ffdshow, superficially only, do you have anything better that that ?

1st burning question:
When to choose Video for Windows and when to choose Direct Show ?

[clsid]

If you installed the ffdshow VFW interface, then you have automatically also installed the DirectShow filter, since the former is a subitem of the latter.

Players use DirectShow. Video editing software often use VFW for decoding (e.g. VirtualDub), sometimes DirectShow.

Avidemux doesn't use ffdshow or any other installed codecs/filters. It uses its own private plugins.

You need to enable those formats in ffdshow that you want ffdshow to decode. It is as simple as that. Some examples of a/v formats that appear in QuickTime files are: H.264, SVQ1, SVQ3, MJPG, Cinepak, 8BPS, QTRLE, AAC, IMA ADPCM, QDM2, MACE.

That's strange. I remember this feature working fine in the original MPC and I think MPC-HC 1.0.10 and or earlier. Maybe try an earlier version, see if that helps?

When I debug the Mpc with dxva(H264), the return value of Execute(the function of IDirectXVideoDecoder) is E_OUTOFMEMORY, I don't know what's mean and how can I solve it ?

[EricAhn]

I think that MC part in DXVA chang some codec routine.

because motion block.

T.T It's too hard to change codec.

Could you check if the texture size is multiple of 16 pixels. Another idea, do you have a dual screen? If so try with lower resolution.

Thanks, Casimir666!
I think i should say clearly.
Now, I want to decoder h264 stream using dxva, and every picture in my test stream has 5 slices;
the sequence like this:
1 BeginFrame
2 Add PicParam data and call execute
3 for (every slice in current picture)
a Add BitStreamDateBuffer
b Add SliceControlBuffer
c Add InverseQuantizationMatrixBuffer d Execute
4 EndFrame

Every thing is Ok in first 4 slices, but at five slice, the call of Execute is error , and return code is E_OUTOFMEMORY. On display window, the content corresponding to first 4 slices are ok and last few lines of window corresponding to last slices are green.
what make me more puzzled is that the decoder process is ok If the count of slices in every picture is less than 5. That mean there must has some params which limits the count of buffer(only 4), I don't know what's that, can you give me some advise, thanks!

[clsid]

Maybe you are forgetting to free/empty some buffer after decoding a slice?

Hum... you method seems correct... Have you try with sample with less than 5 slices?
By the way, if you have such multi sliced samples i'm interrested to have some ;)

[shaolin95]

Guys I have an issue with sound. I am playing MKV files and normally they have DTS soundtracks. I am getting weird crackle and pop sounds using spdif from my computer.
I have tried changing the external filters to something else buy DTS always takes command. I remember I had a similar issue once and somehow making AC3 take charge fixed it but I cant do it now.

Any ideas? BTW, the problem happens as soon as I use CoreAV. When I was using the built in decoder it was fine.

[wary1218]

Maybe you are forgetting to free/empty some buffer after decoding a slice?


what kind of buffer do you mean?
I use the IDirectXVideoDecoder's GetBuffer function to apply buffer and call ReleaseBuffer function to free buffer, I don't know there has any other buffer I don't free?

[wary1218]

If slice's count is less than 5, dxva is ok. The stream is too big to upload, do you have any encoder , such as x264, you can edit such stream by yourself.

Maybe it's an hardware limitation... Did you try to play your sample with Power DVD?
There is a function in DXVA interface that give the number of buffers available on the accelerator (GetInternalMemInfo, GetCompBufferInfo or GetInternalCompBufferInfo i don't remember which one).
Do you have at least 5 for slice buffers?

I'll try to encode a sample with meGui when i had time.

GetInternalMemInfo is the function of dxva1.0, I am using dxva2, so do you know the corresponding function in dxva2.0?

I'll try to encode a sample with meGui when i had time.anyone needs this "patched" for slices build of x264?
(i've seen it recently in x264-devel maillist)..
the author made few testes and he also assumed, that more then 4 slices - is bad for decoding... and currently output bitrate is bigger that it needs to be.. (so i dropped the patching.. but i can try to do that again)
(this is not in git.. 0001-add-support-for-multislicing-encoding.patch)

Hi Folks, 2 quick questions:

1)
I've just installed Vista 64Bit (with integrated SP1) on another PC, and when trying to use any shaders in MPC,
I always get the error "unable to load shader". (GPU is GeForce8600GT, using latest 174.xx NVidia Vista 64 drivers).
Any Ideas on what the reason for this is? It's driving me MAD :devil: (BTW, shaders works flawlessly with my WinXP)
:thanks:

2)
Any news on when (just a rough guess) a fix for the washed-out colors with Vista + EVR-Custom will be added ?
... Casimir ? (yes, I know you can work around this issue with the 16-235-->0-255 shader, but I think it should work
correctly right "out of the box")

:thanks:

Best regards,
raynor

When MPC HC is in full screen but paused my monitor will still shut off per the power saving settings I have. In other versions of MPC this doesn't happen. Is there a way I can control this?

Anyone? Please?

Thanks for the quick and detailed answer thuan, that did the trick.
Shaders are working flawlessly now. :)

Hi guys,

I've been noticing a problem lately with EVR Custom Pres (same goes for VMR 7 and 9 renderless) that involves the red color in videos. Strong reds are very badly aliased and make the picture look awfully bad; I've been experiencing this on my PSP aswell, so I figured it was the way the Video was rendered. Trying to change the render mode to VMR 7 or 9 did not help, but the "original" EVR works fine with smooth edges on the red colored objects.
However, I can't use integrated subtitle fuction from MPC anymore, neither can I choose how to scale the picture (I prefer Bicubic over Bilinear)...

I was wondering if this was a known problem and if it would be possible to be fixed or if there is a way to fix it already.

Ati Radeon HD2600 Mobility
Windows Vista Home Premium SP1
WMPC-HC 1.1.0.2 r479

:thanks:

[MatMaul]

I don't think it is a problem, it's because the YV12->RGB32 conversion done by the graphic card is not very good.
With ffdshow you can use RGB32 as output and tick "high-quality YV12 to RGB32 conversion" : your reds will be a lot better but it eats a lot of CPU.
However I don't understand why this problem do not appear with the original EVR...

[leeperry]

did you enable the PS sharpen script ?

I would guess that it's enabled in EVR custom, and not in regular EVR.

I quit using the PS sharpen script(set to 0.65 instead of 1.60) for this exact reason.

it makes the red extremely pixelated :eek:

[Dixxhead]

Thanks for the answer to both of you.

If it really is a hardware problem like MatMaul suggests, it really would be a shame; but then again, shouldn't it happen also with the original EVR or the Haali Video Renderer? (just found out that latter displays reds correctly aswell, but has some odd lines across the whole vid).

And for the Pixelshader sharpen script, I didn't have it enabled, in fact I had all Shaders disabled, even toggled Pixelshaders to "off"... I also went through all of the scaling methods available (Nearest Neighbour being the worst of course, Bilinear and Bilinear PS 2.0 not making much diffrence compared to Bicubic (0.65-1.00), except being less sharp)...

Through a bit of googleing I found this thread of some forum: http://forum.lowyat.net/topic/539362/+0#entry13716405

The way he says it, it seems to be kind of a "common" bug in the rendering methods (I fixed the blacklevel bug through the ATI CCC, by adjusting saturation, Brightness and Contrast) and also mentions the YUV-Compression/Conversion-issue... Weird thing is he always also lists the original EVR as affected by this pixelation bug, whereas for me it is perfectly fine. Well, I really hope we get to the bottom of this as it is really rather a shame as overall the quality of the Custom EVR is much better and sharper, especially thanks to the Bicubic Scaling! (also seems to work better in conjunction with all diffrent filters, codecs and mpc itself compared to the original EVR)

[khagaroth]

I also have this problem on my X1600, the weird thing is I get this aliasing (and sometimes pixelation - that on big red surfaces) even with forced RGB output in ffdshow. The only way to get around this is to force ffdshow to output in NV12 colorspace.

[MatMaul]

I just made some tests : normal EVR blurs the video SO MUCH that you can't see the other problem anymore, watch those screencaps (especially yoda for the sharpness and the pink stuff for the red problem)

normal EVR :

So, has anyone figured out what regression in the recent code has killed the DVD Menu Highlighting ?

I'd like to use the more recent versions... and generally developers prioritize regressions and functionality over subtleties like the small difference between the red text in the pictures above.

[thuan]

I have the red color problem, too. For me, it only happens when I use MPC bicubic resizer with VMR7/9 renderless or EVR custom. Vista SP1 and HD2400XT with Catalyst 8.4.

[leeperry]

hey Dixxhead, can you make a sample of that video please ?

I can recall I had that pixelating red problem a while ago.......but it never happened again.

I run a HD2600 on XP SP2 with 8.3 drivers/7.11crysis CCC, and I output YUY2 from ffdshow

this is clearly a chroma upsampling bug :
http://images.google.com/images?hl=en&q=chroma%20upsampling%20bug&um=1&ie=UTF-8&sa=N&tab=wi

that's how red looks on my box atm, with EVR custom and bicubic 1.0 PS resize :

Hi, yeah that looks about right...

I have now got the sample, please try it and tell me if it works for you. It is a AVC-Stream inside an AVI Container, just like released by dattebayo (no reencoding either). I usually use the Nero AVC Decoder for decoding AVC, gives better performance than ffdshow. I also tried changing things in ffdshow to NV12 and whatnot, with no viable change happening however (perhaps I do it wrong)...

Well tell me if this sample looks right to you.

http://www.megaupload.com/?d=F7YRWNHS

:thanks:

P.S.: I use the 8.4 Catalyst with the newest CCC.

[leeperry]

well, this looks fine here in RGB32HQ(mandatory to keep the BT601 colorspace mapping when upscaled to HD) :

http://pix.nofrag.com/a/a/2/809c4f281159bdcc4f0d3be8f1b9ftt.jpg (http://pix.nofrag.com/a/a/2/809c4f281159bdcc4f0d3be8f1b9f.html)

I'm using the latest ffdshow from XXL, and MPC HC r403

the latest versions of MPC HC tend to drop frames with Reclock in 24fps@48Hz on my system, randomly between 45' and 90' of play time.

Casimir already fixed this issue for me in r399, and I'm expecting his feedback...but I guess he's on vacation at this point ;)

I think r460 also works fine, but these tests are very long to conduct :(

try with ffdshow in YUY2, and also with MPC HC r403 in the mean time

OTOH, I'm getting problems with MPC HC that doesn't kill its own process when I play several WMV files in a row.

I have to manually kill the process to be able to open a new file :(

[MatMaul]

yes as said before it works fine with RGB32HQ and NV12.
can you try with YV12 ?
I don't understand why we have a very good chroma upsampling with NV12 and a crappy one with YV12, it's basically the same colorspace...

[leeperry]

I dunno who you're talking to, but I've tried YV12 and YUY2 and they both equally look perfectly fine ;)
