EVR CP's VSync prevents stuttering where the screens refresh rate is a multiple of the video's frame rate, which I experienced even with the alternatives.

That said, stuttering was rarely experienced in the EVR renderers compared with Haali's Renderer.

EDIT: Experimental Build offers much better FFPP performance.

Never had these issues. I haven't turned on V-Sync for EVR:CP in, like, 3? years. First happened on a C2D2.4Ghz and 8600MGT, stuttering when there was a lot of things going on. I though the computer couldn't handle the quality or something, then I turned off V-Sync. Magically, all the issues went away.

I never ever had any tearing with V-Sync disabled.

V-Sync = Trash that maxes out the CPU sometimes doing nothing productive. *This may be false on XP, but not for me - I had to wait for flushes to fix tearing*

Haali Renderer = The only way to enjoy HD content on a 2004 desktop PC. No V-Sync though as far as I can tell.

Sparkle GeForce GTS 450, Windows XP SP3


-> changing "Floating Point Processing" settings in Renderer Settings needs MPC to be restarted


Expected: change "Floating Point Processing" setting on the fly without the need to restart the plaer

What you expect and what really is does not have to be the same.
not every setting can be changed during playback

[JanWillem32]

I've broken that function quite a few times during development (although it's not broken in my current developmental alpha build). It's tricky to get a good re-initialization of the allocator-presenter parts during playback when switching these kinds of things.

The Vsync functions are a bit difficult to handle. The easiest way to avoid tearing and stuttering on most video cards is by using the exclusive mode and only enabling the Vsync option in the video card's 3D settings panel. More advanced methods require a constant audio resampler to sync to a specific frame rate. I've been studying methods for those, and the current sync methods in EVR Sync, EVR CP and VMR-9 r.. Windowed mode poses the problem of not knowing when a frame is truly transferred to the backbuffer, as the Windows desktop decides that. There are a few ways of guessing it, but there's no universal Vsync solution for all systems.

Thx


The general consensus seems to be that everyone likes them.

Can my icons be used to updated the MPC-HC '321' logo?

[JanWillem32]

A basic web search for "thumbnail view mkv" reveals that there are two programs that can function as an explorer plugin to generate thumbnails in folder view. As MPC-HC doesn't install anything but the settings in "HKEY_CURRENT_USER\Software\Gabest\Media Player Classic\" and the basic file associations, other system-wide functions, such as generating thumbnails, can only be handled by system-wide splitters, codecs and other plugins.
To be more specific on this item: one or several .DLL files serving as a plugin for the Windows explorer must be capable of splitting a .MKV file, decode a frame, resize it, and output that picture.

[SamuriHL]

Divx has that ability but it often crashes explorer in the process.

[nevcairiel]

On Windows 7 at least, thats a WMP component doing it, but me personally, i haven't got it to work with MKVs yet..

[clsid]

To get thumbnails:

1) registry tweak:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.flv\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{c5a40261-cd64-4ccf-84cb-c394da41d590}"

2) Install a splitter and video decoder

3) On Windows 7 you need to force ffdshow as preferred H.264 decoder. Thumbnails won't work with the MS decoder.

Limitation: the first frame of the video is used as thumbnail. This can't be changed as it is simply how the MS shell extension works for file types that it does not support natively.

[ramicio]

It's only going to get proper support if MS adds it. Chance of MS ever adapting to something that's open source, zero.

Ah, maybe thats what i forgot. WMP needs special preferred decoder settings.

I thought it were possible with only MPC-HC, guess I was wrong.
Thanks everyone for the replies!

[Hera]

Also the experimental build does get stuck after watching a few files in a row.

Possible fix to a hang bug and some useful notes to other devs.

New bug: No change of the picture while seeking to pause. Few freezes when trying to rewind.

I think the problem I have now is that people have tried so hard to fix things that builds of MPC-HC over the past year will no longer play the files I would like to watch all day without dropping constant frames.

I play simple MPEG2 50hz files on a 60hz monitor and I have used MPC-HC since build 900 something, although recently I switched to PotPlayer because it plays my files fine, even with the same decoder and renderer selected. I do no need to use exclusive mode with PotP. I guess there's lots of funky stuff that MPC-HC does better with subs and so on but that's not an issue for me.

Shark codec pack does it.
