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

[Steve8sviq]

Snapshot bug

When taking snapshots I first pause the video at the frame I want, then I use "save image" command from file menu.

Sometimes the frame will move back 1 frame and then save that image rather than the frame I was paused at. So if I'm paused at frame 2222, mpc will end up saving frame 2221. I then have to move to frame 2223 in order to save the frame I want.

This happens using internal splitters and internal decoder or ffdshow decoder.

To reproduce it, try playing xvid avi, such as a tv show released on internet. Right after a scene change happens there is the first frame #1 (for example two people talking and it cuts from one person to the other). Framestep forward one frame using mpc shortcut key to what can be called frame #2. Now try saving snapshot of frame #2. Mpc will move back to frame #1 and save that image.




Will this bug be fixed?

Changes log (http://www.xvidvideo.ru/content/view/7/17/)

(1275-1276):
•Update : MediaInfo header (0.7.21.0);
•Only resize when src and dest sizes don't match and some cleanup of resize code

Using this version I don't get any video from ffdshow. The filter shows that it is connected but the video isn't displayed. The audio plays fine. When I revert to 1274 the video displays fine.

64-bit standalone exe isn't available as a download. Seems you have standalone filters for x64 twice.

[Luyten]

I have problems too in svn 1276: monitor full hd 1920x1080; with PS 2.0 resizer (bicubic or bilinear), no video if a 1920x1080 video is windowed (full screen is fine), and no video if a (for example) 640x480 video is fullscreened (windowed is fine)...
In short, the video is displayed only in... native resolution!?

(Vista H.Premium 64bit, 9600M gt w/ latest nvidia mobile driver, EVR-CP, no ffdshow)

[hoborg]

You got lucky, a bug in the decoder was causing it to work.

tetsuo55, alow me to return to problem with glitch every 2-3s.

I did some more tests with other h.264 decoders and:

haali spliter + PDVD9 (DXVA on) = no glitches at all
haali spliter + Win7 Microsoft DTV-DVD Video Decoder (DXVA on) = no glitches at all
haali spliter + MPC video decoder (DXVA on) = glitch every 2-3s, disapear if stop and play again
haali spliter + MPC video decoder (DXVA off) = no glitches at all

Do you really think it is OK?

All play fine with 1276 rev. + ffdshow(video)

Maybe the problem was that I haven't installed the latest DIRECTX End-User Runtime? I will try again later.

[clsid]

MPC crashes when "D3D Fullscreen GUI support" is unchecked (enabled -> disabled) in the context menu while playing a video in D3D fullscreen.

When enabling D3D Fullscreen from the MPC options, a nice warning message is displayed with instructions on how to close the video. When enabling it through the (context) menu, no warning is shown. Perhaps a warning should be added there as well to prevent newbies from getting into trouble?

Without "D3D Fullscreen GUI support", menus will of course not display properly. Is it possible to disable menus completely in that case? Now it just looks ugly when right-clicking the video.

[THX-UltraII]

I have a question about the controls in MPC-HC:

I play most of the times .mkv files. I use a remote control from Logitech and Eventghost. With this I can set buttons on my remote for Jump Forward. When I pick 'Jump Forward Large' the video only ff or rw for 20 seconds. There is also an option Jump Forward Keyframe but this does not work seems to me. So when I want to see eg. the last scene of a movie I have to click on my remote (jump forward large) soooo many times :). I know that it can be done with a keyboard and move the slider but thats not what I want. I want to be able to jump forward eg. 3 minutes per click or something like that. Is it possible? (maybe I can change the value for Jump Forward Large somewhere?).

Thanks

VC-1 internal decoder is broken w/ this file (http://www.mediafire.com/file/nwnvuwwzhzz/output.mkv)...works fine w/ FFdshow though.

For me a file is reproduced similarly badly, as with my building (gcc 4.5.0), here look:

[Kurtnoise]

I stand corrected. The bug occurs only on windows Se7en. oOoOo my...

[wOxxOm]

[...seems like I'm the first to spot this problem...]

MPCHC builds after 1179 erroneously show ass subtitles inside the video frame on my 4/3 display, whereas the correct default behaviour is to show them below the video frame, if there is space (4/3 fullscreen gives PLENTY of space for subs on 16/9 video content).

Using the internal subtitle renderer, subs pos. override options don't work. 1179 and ALL previous builds of MPC/MPCHC are fine with the same .ini.

Is there a new hidden .ini option?

EDIT: screenshots - old builds (OK) (http://img197.imageshack.us/img197/751/1179q.jpg), new builds (BAD) (http://img197.imageshack.us/img197/8967/1249p.jpg)

Could you make and upload a screenshot to make sure we're talking about the same issue

[donaldtone]

the keystroke of full screen command is wrong: it should be Alt-Return, now it is Ctr-Return.

@everyone looking at this problem, you can open the video in windowed mode, and then drag the bottom of the screen frame down to create the 4:3 effect.
The subs should go down with you, instead of staying within the video frame

[wOxxOm]

tetsuo55, I have only 1179 (ok) and 1249+1276 (bad), all x86 from www.xvidvideo.ru. Where to dl the in-between builds? I'd use a binary division algorithm to close in on the crisis point :-D

[Ger]

the keystroke of full screen command is wrong: it should be Alt-Return, now it is Ctr-Return.
I think it should be F11 actually, since rev 553, in line with some other players. But at some point after that it's apparently been changed to CTRL ENTER and ALT ENTER for full screen without/with resolution change.

[wOxxOm]

tetsuo55, I sorta remember there was some (recent maybe) 'undocumented' ASS (style) tag or [header] property to specify how a sub should be displayed - strictly inside a video frame or relative to a player window... Could this be a lead to the culprit?

I can't confirm this problem on x86 1279 xvidvideo build over here. My computer runs Windows 7 64bit RTM. Are you sure you have "Position subtitles relative to the video frame" checked, and not in disabled or intermediate state?

[wOxxOm]

thuan, absolutely definitely sure - I've just checked it for the 5th time - older version shows subs below, newer builds show inside. The ini is the same. The option is unchecked (as I've said earlier it has no influence in any state). Ah, and my pc runs XP 32bit for many years :-D which will be followed by as many I suppose.

[ADude]

I think it should be F11 actually, since rev 553, in line with some other players. But at some point after that it's apparently been changed to CTRL ENTER and ALT ENTER for full screen without/with resolution change.

All that was part of some change in some recent build that totally messed up the Full Screen commands. This has been submitted to the bug tracker a week or two ago.

[FoLLgoTT]

I noticed that the EVR custom presenter doesn't switch to BT.709 coefficients automatically. EVR standard does with vertical input resolution >= 720. Is it possible to add this behaviour to the custom presenter? I can use the shader to to the 601 -> 709 conversion, but this is not automatic and gives wrong colors when playing SD.

[Zarxrax]

I'm having a very strange bug.
Until yesterday, I was using MPC-HC on windows xp (don't remember which version), and it was working great.

However, then I decided to upgrade to windows 7. I downloaded the latest MPC-HC from the website, and now I am having a really strange problem. I have a few 1080p x264 videos sitting here, and whenever I get to a point after about 1 hour and 32 minutes, in any of them, they just stop working! If I am using a DXVA decoder, then it crashes. If I use ffdshow, then it simply goes black and audio stops. These videos all play fine in VLC.

It's odd, but they all stop working right around the same timecode. Not at the exact same spot, but within a few minutes of each other. When it crashes, there is no error message. It just says the application has stopped working.

[Zarxrax]

Ah, after further inspection, I discovered that this problem was caused by the MP4 source filter. Disabling it so that haali is used, and the problem was solved.

[Luyten]

I have problems too in svn 1276: monitor full hd 1920x1080; with PS 2.0 resizer (bicubic or bilinear), no video if a 1920x1080 video is windowed (full screen is fine), and no video if a (for example) 640x480 video is fullscreened (windowed is fine)...
In short, the video is displayed only in... native resolution!?

(Vista H.Premium 64bit, 9600M gt w/ latest nvidia mobile driver, EVR-CP, no ffdshow)

OK, Installed the latest Directx End-User Runtime and now all work fine!

Is it possible to add this behaviour to the custom presenter? I can use the shader to to the 601 -> 709 conversion, but this is not automatic and gives wrong colors when playing SD.might wanna post a bug report in the sourceforge tracker ;)

[Darth Viorel]

I also have a problem with *.ass subtitles.
By default they are shown in the picture regardless what I do in the configuration. But while playing a file with *.ass subs I can change the position by clicking on subtitles -> styles. There are at least 2 styles with everything but the default set to relative picture position. Changing it only stays changed for the current playback and is lost if I open the file again.
I don't know with which version of MPC HC it started as I don't use *.ass that often, but the problem wasn't there several months ago.

1194 still works normally for me, can you pinpoint the exact regression point?

@everyone looking at this problem, you can open the video in windowed mode, and then drag the bottom of the screen frame down to create the 4:3 effect.
The subs should go down with you, instead of staying within the video frame

as wOxxOm said, with the option "Position subtitles relative to the video frame" set to off and .ass subtitles since r1237 the subs stay in the video frame. but if i right-click on a video while playing and select "Subtitles - Styles" and uncheck there "Position subtitles relative to the video frame" then the subs will go down .
but no problem with .srt subtitles

Ah sorry, indeed, I'm interested in the sub to be kept inside and check for the opposite of what you guys were checking. I can confirm with styled subs, the sub will stay inside the video in any state of the mentioned setting. SRT works as expected.

I noticed this "bug" but if a certain version of dx is required I think mpc should tell the user that and point them to the Microsoft dx page if their version is too old.

[tetsuo55]

@Everyone,

I think we have found the cause of most lockup's, hangs, crashes and black screen problems.
Except for those cases where DirectX (http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=04ac064b-00d1-474e-b7b1-442d8712d553) needs to be updated obviously.
(It appears that the new DirectX version changes behaviour related to scaling, i'm hoping they fixed the stretchrect bug, fingers crossed)

There are basically 2 problems:
1. Several threads reading or even modifying the same data
2. Thread B depending on results from thread A, and being excecuted before these results are ready.

We need to fix out exactly which types of threads use and modify which data, and which threads depend on results from others.

Please help us find the critical points!
Thanks!

You have to remove the 3 *'s for it to work

1. Several threads reading or even modifying the same data
2. Thread B depending on results from thread A, and being executed before these results are ready.
For me internal avisplitter crashes. Default ms avisplitter is working fine, no crashes, tested with latest mpc and winxp sp3.
DWORD WINAPI
CAMThread::InitialThreadProc(__inout LPVOID pv)
{
HRESULT hrCoInit = CAMThread::CoInitializeHelper();<---HERE
if(FAILED(hrCoInit)) {
DbgLog((LOG_ERROR, 1, TEXT("CoInitializeEx failed.")));
}

CAMThread * pThread = (CAMThread *) pv;

HRESULT hr = pThread->ThreadProc();

if(SUCCEEDED(hrCoInit)) {
CoUninitialize();
}

return hr;
}

Hello,
This is a cosmetic bug, but I thought I should mention it: if the playlist is visible and undocked from the player window, when I close and open the player again the player starts with the top part of the window transparent. After play or any window resize, that part becomes normal again.
Latest MPC, XPSP3.

I recently upgraded to the latest version version of MPC-HC (1.3.1249) and have enabled the DXVA codecs for my Intel G45 based laptop. My laptop, an Asus U81A, has an Intel 4500MHD and appears to be supported. I can decode 720p and 1080p x264 videos using the DXVA H.264 codec, however I see artifacting every 15-30 minutes. The display is overlayed with a green/red blocky tinge which disappears after a few seconds.

I originally thought the issue was due to file corruption. However, the issue does not arise when using CoreAVC for playback. In addition, I found the issue with several 720p and 1080p L4.1 x264 videos, all of which passed MD5 checks ensuring that the files were not corrupted. I used the EVR Custom output mode and used the latest Haali Media Splitter.

I am using the 32 bit version of MPC-HC on Windows 7 Ultimate. DXVA also works on MPC-HC x64, however, I have not used it enough to discover whether the problem occurs there. I will test with the internal matroska splitter to see whether the problem goes away.

Thanks again for adding hardware acceleration for Intel G45 based systems. It really helps to keep my system cool, and save battery life. I hope I can get this problem resolved, though. If you need any more info, or if I can be of assistance by testing, please feel free to ask.

if you guys had to pick an OS from a full reinstallation of a HTPC. Which is the best to pick (with keeping in mind the best for MPC-HC and no-tearing).

XP
Vista
or
Windows7 (which version is the current one?)

Jasonplease use this checklist http://mpc-hc.wiki.sourceforge.net/Troubleshooting+guidelines
If the problem still happens after doing all that report it on the tracker on sourceforge.

Also you want to test this special build : http://www.bahnhofbredband.se/~wb118529/9012/mplayercgs.exe

Please test only 32bit for now.
