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

[namaiki]

Make sure you press both activation keys (by default are ctrl+alt) and that 'Keys & remote' is ticked. So, Ctrl+Alt+(numpad minus) and Ctrl+Alt+(numpad plus) by default.

[mikegun]

great, somehow I didn't recognize that there are activation keys.
so this works, now I have to find a way to do this with my mouse ;-)

Hi all,

Just doing a comparison (again) of nvidia's rgb conversion vs ffdshows high quality rgb conversion. My question is, what is the evr-cp renderer setting "output range" 0-255 vs 16-235. Does this mean evr-cp itself will convert to whatever is selected here or just select that as the output range the driver should use when given non rgb content.

Neither setting, using 0-255 in the nvidia control panel color options, gives different output, both look the same to me....

I am using this (what appears to be a 1 frame) vob, to check the conversion quality but with the latesst mpc-hc, the frame always gets dropped lol (I get a report 1 frame drawn, 1 frame dropped). I cannot for the life of me get mpc-hc to draw this 1 frame and show 1 frame drawn, 0 dropped.

If I use ffdshow to do the mpeg2 decoding, mpc-hc doesn't report any frame drops yet I see no frames again. It reports 1 frame drawn 0 dropped.

http://www.2shared.com/file/12140219/5750bb2c/VTS_03_0.html

So my questions are
What exactly does the "output range" setting mean in evr-cp settings.
Can anyone get mpc-hc to not drop this first frame in the sample above, ie show 1 frame drawn, 0 dropped, and actually see output? I used to be able to use it reliably to compare rgb conversion quality of madshi, ffdshow, nvidia etc.
Are there bugs around the reporting of frames drawn versus dropped because the above doesn't add up :)

In essence I want to see if nvidias conversion of nv12 to rgb32 is as good as ffdshows yv12 to rgb32 which I have been using for months.

It's extremely bothersome having to install the latest DX runtime, why not just use the runtime included in Win 7?

[Razoola]

I just wondered any devs views are on adding DX10 support so nvidia users can take advantage of 10bit RGB output? I assume such a change would require much work or else it would have already been done?

Among other things a scaling bug has been fixed recently.

View > renderer settings > presentation > 10bit RGB
You need to use EVR-CP for this.

[THX-UltraII]

tetsue, when would someone need this 10-bit option?

[tetsuo55]

when you want less-inaccurate colorspace conversions. and have the cpu-cycles to spare.

So basically always unless it causes stuttering.

[Razoola]

Maybe I did not put my question correctly. What I meant was 10bit RGB over HDMI. The nvidia drivers do not allow this with DX9, only DX10 from what I understand (maybe im wrong though). When one chooses the 10bit RGB option MPC-HC does 10bit surface and backbuffer but the display is still 8bit. What Im suggesting DX10 support will allow nvidia users to output 10bit to the display also (providing the panel supports 10bit of course).

Since the latest runtime appear to be required for custom presenters only it would be nice to support default EVR better, what I miss most is Pan & Scan. In my player I noticed EVR having bugs preventing to implement Pan & Scan, I worked around that scaling the WinAPI control hosting dshow. I'm not sure how KMPlayer has implemented it, IIRC Spy++ showed it uses a way different from mine. Maybe somebody can make it work in MPC, maybe it's not so hard, maybe the author of other players can be asked how it can be done.

I did have a display that was 10bit but not presently. I could never get 10bit output with the nvidia card. I did read somewhere that the nvidia drivers only support 10bit RGB display over HDMI under DX10 and 8bit under DX9 so I put it down to that. I have just spent a short while trying to find where I found that info but cant :(

Maybe there someone here that can confirm this with a nvidia card and 10bit panel? Do you see 10 bit used with 'surface', 'backbuffer' and 'display' in osd stats with EVR-CP and 10bit presentation option enabled?

[mark0077]

Yeah for me with a GTX295, Windows 7, HDMI output, I get a D3d 9 error when using 10 bit output.

Simple question that a search did not seem to answer it; Can subtitles be moved on the fly when using the internal subtitle filter?

☑ Allow Animation when buffering

☑ Allow Animation when buffering

So that's what that thing does. Thank you so much. It works perfectly.

[Killroy™]

☑ Allow Animation when buffering

OK... that works for .SRT subs but IDX/SUB subs does not seem to allow changing screen position. I figured that but is there a way to override the placement made by the IDX?

[cavinsmither]

It have additional functionality with great performance and also supported with window XP,vista and window 7.Its compatible with hardware and have a good reliability.
Its really good player .

[clsid]

Subtitle animation != subtitle positioning

What you are looking for is the "override placement" option.

[Killroy™]

What you are looking for is the "override placement" option.

Cool! That works for both types of subs. Is there a shortcut (keyboard or otherwise) that you can use to change the sub position without going to OPTIONS->SUBTITLES->Override Placement & manually changing the numbers? I am basically trying to find a way to quickly change the position of the subs on scope films that have the subs outside of the active picture area and quickly move them into it.

Thanks.

[Razoola]

It looks like nvidia did not fix the issues with MPC-HC which were in 196.75 (before it was removed) in the newly released 197.13. What this means is EVR modes in MPC-HC do not display video correctly when the player is in windowed mode (there is real bad stutter). There is no problem if you use fullscreen however.

This is on windows 7 64bit btw, not sure if the issue is on other OS's

[mark0077]

Yeah those new drivers are bad when not using a fullscreen exclusive mode. Rolling back.

[Superb]

Using 197.13 w/ 8000GT on Win7-32bits:
1. Regular EVR works fine.
2. Custom EVR works fine. Stutters a bit after seeking, but then works again (after a few seconds).
3. EVR Sync sometimes stutters. Maybe ar-jar can check the cause? It happens on a seek. When it works fine (http://i42.tinypic.com/4lk778.jpg). When it stutters (http://i41.tinypic.com/dxmkjt.jpg) (the red line goes up and up).
That's w/ present at nearest VSync & w/ Bicubic (-0.75 ps2.0).

I tried that with my ATI HD2600 and the image turns all weird orange colors, kind of very groovy austin power looking effect (sorry for the lame description).

Hi Casimir666,

There seems to be a long standing bug in the mpc hc m2ts splitter, which affects almost all criterion blu rays (they mostly use mono):

I made a small 5 sec sample, where you can hear the bug pretty clearly. Interestingly the video ends after 5 seconds and the audio is still playing another 5 seconds with mpc hc + ffdshow(as a audio decoder) at half speed:

http://www.mediafire.com/file/omtnmdnjiyy/sample.m2ts

tal.aloni, debugged this in ffdshow and found that the sample works fine with the haali splitter, so the bug must be in the m2ts splitter of mpc hc.

If you find the time, could you please look at this, it seems easy to fix!

Trying to watch some Criterions, bump.

[Leak]

It's extremely bothersome having to install the latest DX runtime, why not just use the runtime included in Win 7?
Last time I checked MPC-HC was still using DirectX 9 - and Windows 7 only ships with DirectX 10 and 11, which both aren't backwards compatible to DirectX 9.

[Snowknight26]

The issue where external FLAC tracks cause the video to be played back at ~50% of the normal speed is still present. :\

[73ChargerFan]

My DTS-HD over SPDIF issues are still present. :( The sync renderer is awesome, but I can't get dts core out of mpc-hc for ever. No issues with VLC 1.0, but their renderer stinks. Affects mkv, m2ts, Windows XP, Windows 7.

Does anyone else have similar problems? If so, PM me and perhaps we can see what is similar.

[ar-jar]

Does your board actually support 10bit RGB? (Use DirectX Caps Viewer to check). My board doesn't and the screen turns psychedelic when I try. There are too few checks in mpc-hc so it just happily tries most of what you throw at it. -A

[Peekstra]

I noticed that I get different image when using ffmpeg instead of DXVA

The DXVA image is lighter and contains visible vertical lines.

http://i.imagehost.org/t/0403/banding.jpg (http://i.imagehost.org/view/0403/banding)

and the ffmpeg decoded image is much darker without any visible lines:

http://i.imagehost.org/t/0631/banding2.jpg (http://i.imagehost.org/view/0631/banding2)

The ffmpeg decoded seems to match my 0-255 calibrated monitor settings.

I'm not sure if the lines are also present in the ffmpeg decoded image as it is to dark for me to see (and it's not exactly the from the same frame either).

MPC is set to output in the 0-255 range so I'm surprised to see such a light DXVA picture here....? And are those lines really present in the source?

Is there any way to add a keyboard shortcut to VIEW--->Pan&Scan--->Scale to 16:9 TV?

[THX-UltraII]

When I use EVR SYNC as renderer and press CTRL+J while playing my HD content I see a notification: 'No FGT'. What does this mean?

[namaiki]

You're using DXVA?

Stands for: No film grain technology. Beats me what it actually is though my Intel card says Intel ClearVideo(TM).

[Mike5]

AFAIK Film Grain Technology is used to separate grain from film during the encoding process and thus to better encode the movie.

During decoding, a separate process is used for grain. If DXVA is FGT capable, grain is decoded by hardware, otherwise by software.

[namaiki]

So, say for instance, ffdshow video decoder filter etc, usually adds the grain back?



edit (to below): yeah, I guess it is pretty off topic.

[Mike5]

It is required for sure for H.264. The MPEG2 support was added later. As for VC-1, I don't know.

I think the FGT support is included in the libraries used by ffdshow, like ffmpeg, but we should ask in the ffsdhow thread.

[decapitado]

Is it possible to add a patch to auto-load external subtitles instead of embebbed ones?

[tekNerd]

Hey...

1. When I open my dvbt device it works, but I get this:
http://img709.imageshack.us/img709/4830/dvbfilters.png
Is this normal?(This doesn't happen when I use inbuilt codecs)

2.Is it possible to have to automatically save the subtitles downloaded with the name of the video file (as SMplayer does it)?

[BelowSky]

I'm having random partial corruption in some videos during H.264 playback with MPC-HC (DXVA enabled).
I tired every version, stable finals and unstables from svn, x64 and x86.
I also tired finals and betas of Catalyst v 9.11, 9.12, 10.3.
And I don't know if this is related, but I'm having the same corruptions in FFDShow too .
Once I disable DXVA, corruptions disappear.


All files that I'm having problem with, play just fine without any corruptions in WMP12 and PowerDVD (Trail version).

Windows 7 Home Premium x64; DirectX Feb 2010; Mobility Radeon 4650.

nVidia PureVideo3 or 4 and Microsoft DTV-DVD Decoder.

There are no encoders that support FGT though so hardware decoder support is moot.

[hunter2]

Do you also have this blocky picture on H264-files with DXVA on ATI-cards? It happens only with files that have 480p-resolution for me.

Files with 720p and 576p-resolution run without errors on my ATI-GPUs with DXVA activated (tested with Radeon 4770 and 5450 and 5770).

This happens since Catalyst 10.2, I tried older versions of MPC and they have all the same bug now. So it seems related to changes in the GPU driver from ATI.

The DXVA-enabled FFDShow decoder does show the same errors with the latest GPU-drivers from ATI.

Same thing happens to me, Catalyst 10.3 didn't fix it either. Something changed between 10.1 and 10.2 to break 480p DXVA.

[Mike5]

There are no encoders that support FGT though so hardware decoder support is moot.

I know that FGT is mandatory for H.264 and MPEG2 for HD-DVD (DVD forum specifications), and thought the same was for Blu-Ray, but I don't have any sure information or link for Blu-Ray.

[Remicade]

What is FGT ???

[edigee]

FGT = Film Grain Technology (bandwidth-saving technology for HD video)-first introduced by Thomson in 2005. In simple words it's a process whereby grain is filtered from a source before encoding and then added back in the player.
