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

[avivahl]

The Sync Renderer doesn't use the correct AR from the Matroska file I'm using. Anyone else having this problem?You might wanna post a small sample for ar-jar to look at (in the GothSync thread (http://forum.doom9.org/showthread.php?t=148221)).

[BatKnight]

Is the Audio Renderer (under Options->Output) set to "System Default"?
Did you try completely resetting MPC-HC's settings (deleting its registry tree under HKEY_CURRENT_USER\Software\Gabest) and using the latest build from XvidVideo.ru? (sorry if this seems too trivial)

Yes, did both.

Another thing I've noticed is that using ffdshow filter I can make unsync even more noticeable if I right-click during the playing of the movie, and select anything or click around. The video then gets very noticeable unsynched, but it tends to auto-synch but never gets perfect.
When using the internal MPC-HC decoder I can right click, select anything and mess around that the video doesn't unsynch.
I am not using DXVA and my CPU is powerfull enough to play the video using only an average of 35%.

I've manage to find that this only reproducible on VC-1 files when using ffdshow at wmv9. Libavcodec vc1 doesn't suffer from this problem.
May a moderator please move these posts to the ffdshow thread, if possible. I'm sorry for any trouble.

Using Sync Renderer with the 'Present at nearest vsync' synchronization option with build 1.3.1486:

Ok sorry, I'm definitely not nuts. If I change the renderer to EVR CP, then untick all the vsync options under Renderer settings, and then change the renderer back to Sync Renderer and then look at the vsync options again, 'Vsync' is ticked but all 3 are greyed out ('Vsync', 'Accurate Vsync' and 'Alternative Vsync'). I then proceed to play a movie - terrible tearing and stuttering.

I then change the renderer back to EVR CP, tick 'Accurate Vsync' and 'Alternative Vsync' (along with 'Vsync') and then change the renderer back to Sync Renderer and look at the vsync options again, all 3 remain ticked but greyed out. I play a movie - play back is perfect ( I tested this over and over and the results are the same every time). So even though the vsync options are greyed out they still have an effect on playback.

Could someone please explain if this is to be expected or not - I had assumed that the vsync options were greyed out because they are not meant to be user selectable with Sync Renderer (i.e Sync Renderer had it's own vsync method and the options were greyed out simply because the render does not use them).

I have found something similar.

I found that if I used EVR CP with 1453 (shortly prior to Sync Renderer) and then used 1465 with Sync Renderer and then went back to 1453 with EVR CP, there were different results the second time with 1453 than the first time.

Similar things occurred with different versions and different orders.

When I rebooted the PC in between each version change, then I could tell each version's performance (as would be predicted by the code changes).

So there is either a memory leak, or else some other way in which different versions affect each other, such as options not being cleared properly.

[Nitrius]

Do you use the latest ATI driver?
Which filter decodes the video (using DXVA)? The internal H.264 DXVA decoder? The one that comes w/ Windows 7 (Microsoft DTV-DVD Video Decoder)?



Using ATI 9.12 Hotfix, tried with regular 9.12 as well. MPC Video Decoder was i using.

[roytam1]

for Sync Renderer, in my config (x1950 Pro, XP SP3) it drop frames, while EVR custom with Alternative VSync work perfectly.

[hdboy]

Anyone with a 24Hz and 60Hz capable LCD, please try to reproduce this on a 1080p VC-1 or H264 movie where you get sufficient face close-ups to notice this unsynch.

Bat

I used to get this unsynch with 24fps on the previous build, so I couldn't use 24fps. the new one seems to have fixed this. this is with 1080p. I have a Sony Bravia LCD that accepts 24 or 60. maybe you can post a sample for me to try.

I think your TV may be doing some extra processing when it's receiving 24fps input as opposed to 60fps, like frame insertion, so the sync is off. if your filters are doing more processing of their own, that just makes the synch worse.

[Mixer73]

Guys with all the recent fixes from compiler warnings and things all the common methods I would make MPC-HC crash are gone, I just want to thank all the devs for so much work in polishing MPC-HC lately, its brilliant.

[NiFa]

I use EVR custom pres. because it gives me smoothes playback, but only if EVR buffer is in use and filled, I did try sync renderer, but I got heavy stuttering with it despite what settings I used.
How can I force the EVR buffer to always be filled? It worked just fine with build 1453, but not with 1486.

Hi, thanks for the report. This is not expected bahavior. Those flags should be entirely ignored by Sync Renderer. Which means that something else probably gets initialized when you switch renderer back and forth. I shall look into the code and see what I can find.

I've seen something similar with my setup: DXVA2 is not activated with EVR unless I play the same file with the same decoder (NVidia) with VMR9 first (which comes with DXVA1). Do you see whether the use of DXVA changes between the two uses of Sync Renderer? -A

[ar-jar]

The Sync Renderer doesn't use the correct AR from the Matroska file I'm using. Anyone else having this problem?

Do you get the correct AR with EVR and EVR custom? I have issues myself with AVCHD files from my Sony Handycam. The MPC video decoder doesn't send the correct AR to the renderer in those cases. -A

Ok, I didn't realize this was an existing problem. Your file plays fine on XP with the internal MPEG2 decoder, with the NVidia MPEG2 decoder and with the CyberLink Video/SP decoder. And on W7 with the internal decoder. Unfortunately I don't have the Elecard MPEG2 decoder installed and it seems that you deleted it from the download site. -A

[Djon]

Hi, last SVN build (XvidVideo.ru) can't play mp4 files properly (both 32 & 64 bits).
SVN1453 works, but SVN1486 acts as if my PC wasn't powerful enough, sound and subtitles are good but the video freezes to death (something like 1 or 2 fps)...
I guess it's linked to the new Bento4 library.
Anyway thanks for this software :)

Well, now I've noticed it as well and second this question :)

[sneaker_ger]

Do you get the correct AR with EVR and EVR custom? I have issues myself with AVCHD files from my Sony Handycam. The MPC video decoder doesn't send the correct AR to the renderer in those cases. -A

I just tested it: the same problem appears with EVR and EVR Custom. Doesn't matter if I'm using Haali's or the internal splitter.

[Nitrius]

Using ATI 9.12 Hotfix, tried with regular 9.12 as well. MPC Video Decoder was i using.

Changing the filter to use Microsoft DTV-DVD Video Decoder, seems to cure the problem. Also using Sync Renderer output also seems to help.

[ADude]

I'd be willing to bet that some of the people who have been getting stuttering or frame drops from Sync Renderer will find that goes away if they do a reboot any time they change version or renderer. Probably that is a bug in MPC-HC or the renderer(s).

[NiFa]

Nope, reboot didn't fix my problem with sync renderer I just can't get it work no matter what settings I try. I was happy with EVR custom pres. + accurate vsync compination because it worked perfectly and EVR buffer was always filled.
Now EVR custom pres. + accurate vsync doesn't work because the EVR buffer doesn't work like it did until I tried build 1486, now I can't get it work even with 1453, does someone have any idea what happened?

Did you reboot again after changing back to 1453 ?

[NiFa]

Yes I did reboot, weird thing is that I also uninstalled and reinstalled ffdshow (revision 3154), now only videos where framerate is 30Hz have problems, and other videos work fine. My settings are same as they were when everything worked perfectly when I used ffdshow rev. 3154 and mpc-hc build 1453.

Hello Everyone,

We are going to change the policy for default settings.
The new policy will be:

"All functionality will be enabled by default, except for those that are designed to reduce functionality."

The reason for this decision is:
* A lot of developement time has gone into developement, it would be a waste not to use them.
* Without regular use, bugs and other issues will not be uncovered.
*uniformity, no more opinion based discussion over default settings.
*MPC-HC will be able to play all supported formats by default without the need for any external filters (said differently: everytime you disable a filter, you basically force the user to google for an alternative)

There are 2 scenario's where the default can and should be disabled.

1. a dev is working on something, the thing is unstable, the dev does not require end user input to fix it. The feature will be disabled by default and get an "unstable" warning in its name

2. a fatal bug is found in the feature, this bug is defined by objective research and proven with samples/screenshots/etc...
All this should be on the tracker for disabling by default, staff will make a re-enable ticket and disable the function.

By default VC1 will be disabled due to the problems with interlaced content, most windows versions already have a VC1 decoder included, so an alternative is available.
It will be enabled again when interlace detection is included, to redirect interlaced VC1 to an external decoder.

Please help out up front by creating well troubleshooted tickets for bugs that you think are critical in deciding to disable a feature.

[ar-jar]

Yes I did reboot, weird thing is that I also uninstalled and reinstalled ffdshow (revision 3154), now only videos where framerate is 30Hz have problems, and other videos work fine. My settings are same as they were when everything worked perfectly when I used ffdshow rev. 3154 and mpc-hc build 1453.

You have not by any chance also switched from Haali splitter to the internal splitter? I get stuttering with the internal splitter + ffdshow when playing blu-ray movies. With Haali + ffdshow they play fine. Also with the internal splitter + internal video decoder.

I don't think that the Sync Renderer settings should interfere in any way with the other settings so they should be backward compatible. Except that you need to re-select a renderer when going to an early version. They graph builder seems to gracefully revert to the default renderer when it can't find the selected one. But that may not be what you want.

Sometimes, for a totally fresh start, I go to the registry and delete the "folder" HKEY_CURRENT_USER -> Software -> Gabest -> Media Player Classic. But I of course lose all Favorites and other settings. Do this only at your own risk.

[NiFa]

No, I have whole time used Haali's splitter + ffdshow, I also did remove mpc-hc registry keys, I'm starting to think that this is related to ffdshow rather than mpc-hc.

[Perls]

Rev 1486 breaks interop with re-clock using EVR custom renderer. Instead of detecting the movie frame rate generated by re-clock it seems that now mpc makes its' own decision about the movie frame rate which works badly for blu-rays on a 50 Hz panel. Rev 1453 works perfectly together with re-clock.

[DMD]

Sorry, but in 64-bit version where you find the file mpc-hc.ini?
at C: \ Program Files \ MPC HomeCinema (x64) does not exist. :confused:

Thanks

[Steveo08]

is it possible to change the auto hdmi mode for 1080p@24 at 23 Hz and not with 24Hz, because you only get with nvidia real 23,97Hz at 23Hz and not with 24Hz.

Not sure exactly what you mean but 23.976 fps blu-ray @ 50Hz works fine here w/ Reclock. It speeds it up to 25 fps as it should. Works both with Sync Renderer and EVR custom. I'm using my latest 32 bit build (1487). Sync option Present at nearest vsync if using Sync Renderer.

[nae1986]

There is a bug in all recent versions (including build 1486). Sometimes, the "mpc-hc.exe" process doesn't close.

Here is how I can reproduce the bug:
I have a lot of media files associated with MPC-HC. If I open one file, then close it, then onen another one, then close it and so on, eventually, "mpc-hc.exe" process will remain open until I close it manually using Task Manager -> Processes.

MPC-HC build 1486 (32 bit)

Hi Devs, this is regarding about mpc audio renderer. I can hear sound by using it,
but this picture http://img64.imageshack.us/img64/6159/mpchc.th.png (http://img64.imageshack.us/i/mpchc.png/) at the bottom right corner show speaker with a cross, just wonder is it correctly display and what does it means. Apart from that, I get random issues of no sound output while playing a song from CD, its like the song play half-way thru' and out of suddenly no sound is heard, just wonder is it happening to anyone else. If I pause and play again, the sound is able to hear again. My window environment is Vista(x86), creative audigy for sound. Hope someone could understand what I am trying to tell, I regret about my poor language. Thanks.

I have also the "speaker with a cross".
Also I have no control on the MPC volume. Moving the volume control doesn't change anything for me. I can even enable mute and I still have the sound.

MPC Audio renderer is using exclusive mode. It was conceived to be used with bitstreaming HD-disc audio (TrueHD, DTS-HD MA) so you guys are better off with Default DirectSound (the default renderer).

Hmm, strange, I just tried 1488 and my problem remains. Pressing ctrl-j with EVR custom the frame rate in the upper left corner is fluctuating between 23.956 and something else that is displayed for such a short time that I can't identify it. The red/green graph looks very similar to when re-clock is not used and there are also sound problems. With 1453 frame rate is reported as a steady 25.002 Hz and the red/green lines are parallel. I'm on vista32 with an ATI 4550 and catalyst 9.12. Just installing 1453 on top of 1488 while keeping previous setting immediately cures the problem...

Edit - I'm using lpcm over hdmi via re-clock re-sampling for the sound

This is probably not relevant to your actual problem but I should say that Sync Renderer reports the original frame rate (23.976) even though it is speeded up by Reclock. I will fix that any of these days. It is easy to see from the graph though if the green and the red lines stay parallel or not. 23.976 @ 50 Hz exhibits a very characteristic saw-tooth pattern.

What filters do you have in your graph? -A

[Shakey_Jake33]

Very basic schoolboy question, but does the Deinterlace shader within MPC-HC automatically not apply when watching interlaced content? Or should I disable it entirely when watching progressive content? Would obviously be easier to leave it on, but it's probably a bad idea if it attempts to process progressive content.

[joikd]

MPC crashes if I have "interlace flag" checked in the output of ffdshow when using EVR CP. It doesn't crash using EVR. I need this option checked in order to have my 5750 do the deinterlacing (VA), but I would still like to use EVR CP. Is this a setting issue on my side, or an issue with ffdshow and/or MPC-HC? Any help would be appreciated.

I have now also tried the sync renderer with 1488, it behaves exactly as evr custom (as far as I can see), i.e saw-tooth graph. I use ffdshow software decoding for both picture and sound, but I've also tried with coreavc for AVC and internal dxva filter for VC1, no difference. I also tried vc1+truehd, vc1+dts(core) and h.264+lpcm films with the same result. In addition to this I disabled frame time correction, no difference however. Re-clock seems happy enough though and shows a green icon.

Check if 10bit RGB is checked. You can't use hardware deinterlacing with 10bit unfortunately.
