Note: I know that several constants are not used yet but might be useful for future patches.

Thanks, we can use every patch you can think off with regards to splitter problems

i can reproduce with the latest version 1137, please add this issue to the tracker.

I hope another ffmpeg updates fixes it.

I know of a show stopping bug, but haven't thought about it for a long time, and am surprised that it isn't already in the bug tracker.

dts 1536 over spdif stutters

My work around is to use spdifer. I'll test & verify with latest build before adding to the bug tracker. I'm using XP.

I can't believe the love shown by Beliyaal, Tetsuo55, Casimir, Alexins... Sorry if I have forgotten a regular contributor.

I think I've seen 100 builds since I started really using MPC-HC, as a former Zplayer and KMplayer user, I can now say that with the right settings MPC-HC gives perfect playback for me when its configured right.

Awesome job devs, You deserve a pat on the back for your commitment to a sometimes thankless job.

On another note is the xvidvideo.ru site down?

Xvidvideo.ru is down, here latest 1141 build :

thanks for providing this version. i was curious about the improvment with DXVA.
now files with 12-15 ReFrames will have DXVA with XP (SD and HD). only files with Reframes 16 will freeze.

What Output use ??? Under XP only in "system" no limit on ReFrames.

Regarding bug:

http://sourceforge.net/tracker/?func...61&atid=854651

If I understand the report correctly, I am unable to reproduce.

Using the latest MKVtoolnix I've muxed a 16:9 avi to MKV, forcing the aspect ratio to 4:3 in the "Format Specific Option" tab for the video track.

As expected, the resulting mkv file is played by MPC-HC with the video squeezed.

Maybe it was simply a badly muxed file, or may some other patch has also fixed this problem (the bug is pretty old, august 2008, with no followup).

Anyway, we do not have a sample and we can't ask the anonymous submitter: if nobody else can reproduce I think the bug could be closed.


tested with the madVR, Haali, ERV and VMR9 rederers

on XP MPC-HC couldn't decode files with more than 11 ReFrames. it worked with CoreAVC (but even CoreAVC turns to software-mode on files with RF=16)
it only works now after Casimir666's changes in rev1141. so the DXVA limitations for XP inside MPC could be removed now.

but there is a problem now for me with some "more demanding" 1080p files: the frame rate judder is sometimes chaotic probably depending on the scene, and if i select the BicubicResizer instead of the BilinealPS2.0 then it gets even worse, and even worser if i enable some Shaders (YV12Chroma + Sharpencomplex2).

rev1136:


rev1141:


sample here

as a sidenote: before 1141 it was possible to have more than 1 instance of MPC-HC and DXVA, now MPC falls back to the ffmpeg on the second instance

edit: some of the SD anime encodes i have will get older frames inbetween on DXVA playback, and then video freezes. audio continues. in this sample video freezes at 0:17 sec
i hope that it's not my graphics-card giving up on me )

After display, the flag bUsed will set to 0 if this frame will not be reference by another frame.
So, the Index may be using for next decode buffer immediately.
The "decoded" frame will be updated on screen immediately caused by the same buffer index "nPicIndex" as previous display frame.
What is the problem? Does someone have any idea?

Is any one have idea about the buffer question?

I added this bug to the tracker

http://sourceforge.net/tracker/?func...61&atid=854651

Thanks for fixing it. Now all my HD videos with 16 Reframes play without freezing.
With SD video encodes (less than 1280x720) and 16 Reframes DXVA is not active. But there is one rare occasion when SD videos with 16 Reframes use DXVA and video freezes - linked files.
When I start the main file and it is encoded with 10 Reframes for example MPC-HC uses DXVA. Linked file is encoded with 16 Reframes and when MPC-HC plays it at some frame video freezes. If I play the linked file separately, MPC-HC won't freeze because it doesn't use DXVA. It's the same as the bug above but if it's needed to add another bug to the tracker I'll do it.

I make test version - http://aleksoid.tosei.ru/mplayerc_1143_test.7z - work AR, fast move/switch between monitors, window and fullscreen mode.

Here is a possible solution for the various crashes/corruptions related to multi-screen problems and UAc prompts ETC..

Totally different ways to recover it based on surface vs texture mode, and you basically have to destroy every last resource, then call device->Reset(), the re-initialize it all again. I wrapped all the code I could to avoid code duplication. And it turns out just resetting isn't enough for the issue with textures when you resize windows, so that still re-initializes everything. Oh, and you can't just re-initialize when you lose the D3D device: it'll actually crash the application. You have to reset the device before you can use it again, period. And when you lose the device, in order to try and recover it, you have to release all the old resources first, so you have to then write protection checks at the top of every user-visible function to make sure they don't try and access resources you released while trying to restore. Because you see, it won't restore when you're in the ctrl+alt+delete menu, it'll keep failing and you have to keep trying over and over until it works. And you can't sleep once you detect device loss, because then the audio will hang.

I can fix unload, but the title bar thing is a limitation of Windows deadlocking userspace code when you click on it. Linux and OS X don't have that problem.

You can try muting between WM_(ENTER|EXIT)SIZEMOVE messages, assuming you can intercept them.

I mentioned updating the baseclasses before.

The newest release can be found here:http://www.microsoft.com/downloads/d...displaylang=en

On 27-4-2009 MS said they would not be updating the directshow baseclass redist dll's, this probably also means that they won't be updating the baseclasses at all. However they could still update them through windows update (redist is no longer required with XP sp2 or newer)
I guess this is a logical step seeing as all the focus is on media foundation.

[tetsuo55]

I've noticed that some parts of MPC-HC and more often external filters require admin rights to work correctly(At least on windows 7).
(See also this related bug report http://sourceforge.net/tracker/?func...61&atid=854651)

Here is a MS tool that can test applications for problems running as a limited user: http://blogs.msdn.com/aaron_margosis...d-preview.aspx

Basically MPC-HC(or the external filters) should ask for admin rights only when really needed. (prompt uac on action that requires admin rights if not already running with admin rights)

EDIT:
Here is a document explaining the admin rights only when needed functionality

Revision 1141 seems to cause problems with DXVA in certain files. Example follows:




As you can see in this screenshot, playback is not smooth but the video stutters. The same exact file has no such problem with revision 1137.

Unfortunately I don't know how the file was encoded, it is a freely available anime fansub. The problem seen is 100% reproducable, happens every time with revision 1141 with this video, never happens with rev. 1137.

[tetsuo55]

We need a sample.... (you will have to cut it). Also please post a media info log in [ code ] [ / code ]

[chiyuwang]

when using VMR9 renderer it crashes to dxvadecoder.cpp line416

Unfortunately I do not how to cut matroska files, nor what a media info log is. I don't produce videos, only play them. I assume it cannot be too hard, but I got no clue atm.
