I'm playing a 720p mkv file with VMC and the decoders are FFDShow. Do I need a fast cpu for playback? I have it setup default in FFDShow config.

 

[blackmax2k1]

When I use GraphStudio playback is fine. CPU jumps all around from 35 to 65% but no stuttering. So do you think the load of MC is too much? It plays fine with other programs like MPC or Zoomplayer. I think maybe the microsoft decoders take over instead of FFDShow when played in MC.

 

[blackmax2k1]

I just tried Win7DSFilterTweaker_1.3.exe to make FFDShow the default filter and not Microsoft. Didn't help.

Try:


- Haali Media Splitter . If your OS is x64, 64-bit version

- MPC Video Decoder (MPCVideoDec.ax) (x86 or x64 according to your OS). Register it with the command: %SystemRoot%\\System32\

egsvr32.exe [the folder location]\\MPCVideoDec.ax. Or copy and paste the following to a notepad:

Code:

@%SystemRoot%\\System32\
egsvr32.exe MPCVideoDec.ax

and save it in the same folder as MPCVideoDec.ax as, say, "install.bat". Then double click it.


Make MPC Video Decoder the default H.264 decoder by Win7DSFilterTweaker.

what build of windows 7 are you running?

In some of the builds (7057 onwards off the top of my head) its very hard to override the built in microsoft decoders. I'm not sure the tweakers and MCDU tool has caught up.


I ended up having to rename a couple of files in windows/system32 (mpeg4s.dll and one other, sorry not at computer at the moment).


In Win7 they've got a new framework called Windows Media Framework which is a replacement for directshow. Any WMF filters (eg the microsoft ones) will override any directshow filters (eg ffdshow) despite the filter priority you set for the ds filter.


Things like Zoomplayer and MPC-HC have their own graph builders so don't rely on the codec priorities of the underlying OS, which is why its easier to set them up to use ffdshow on Win7.


Hope that helps.

 

[bryanchicken]

oh, and are you able to connect to the MC graph using graphstudio to see what filters it is actually using? To do so you need to register proppage.dll in windows/system32. I usually get it from the SAF thread on the mediaportal forum.

While MC is playing use the 'connect to remote graph' option in graphstudio.


I assume MC exposes its graph so this can be done. I don't know for sure.

Small corrections:


- Windows Media Framework -> Media Foundation (MF), introduced in Vista and intended to replace DirectShow (gradually).

- WMF filters -> Media Foundation Transforms (MFT); the notion of filters is specific to DirectShow.

- Microsoft DTV-DVD Video Decoder (msmpeg2vdec.dll), Win7's built-in MPEG-1/MPEG-2/H.264 video decoder, is still a DirectShow filter so that you can use it with a DirectShow player such as MPC HomeCinema.


BTW Win7DSFilterTweaker works just fine with Windows 7 RC (Build 7100) x86 & x64.

 

[bryanchicken]

you can still use it as a directshow filter, but it overrides other directshow filters despite setting the ds priorities.


I've spent HOURS trying to disable that thing, which is what the OP seems to want to do, assuming that it is getting used by MC instead of ffdshow.

 

[renethx]

Yup, you are right. Saying Win7DSFilterTweaker works with 7100 is not helpful for OP.

 

[bryanchicken]

to be honest, i've tried so many different builds of Win7 with so many tweaking tools and the MCDU that i'm probably more confused now than i was at the beginning

In the end, like i said, i ended up renaming DLLs in my system32 folder (the names of which i got from graphstudio when the microsoft transform (cheers) kept getting picked.

I've yet to find any negative impact of this, but i haven't done a lot else other than HTPC based stuff.

I did it for divx/xvid (mpeg4??) too, because i wanted ffdshow to do some post-processing.


Why microsoft has gone down this ultra confusing route i've no idea. I'm all for advancement (eg, replacing of old directshow) but making it so darn hard to replace the sub-standard MS transform is a baffling decision. Maybe the final release will rectify this.

 

[blackmax2k1]

Yeah I'm using 7100 build. renethx, I'll try your suggestion tonight.

remember that these are betas, they are still working things out too.

Hmm, I don't see any problem with Win7DSFilterTweaker. Make sure to check ffdshow video decoder configuration > Tray, dialog & paths > Tray icons > Modern or Classic. If ffdshow Video Decoder is loaded, then you will see an ffdshow Video Decoder icon in the system tray. Microsoft decoder also works fine with 1080p H.264 MKV files inside the 7MC internal video player. Pentium E5200 2.5GHz CPU usage:


- ffdshow: ~50%

- Microsoft DTV-DVD Video Decoder:
- MPC Video Decoder:

All with Haali Media Splitter (perhaps this is more important than the decoder for smooth playback).

 

[blackmax2k1]

I'm using a E2140 1.6 chip with 2GB's of ram. That should be good enough right?

 

[renethx]

1.6GHz is good for 720p without GPU hardware acceleration (e.g. ffdshow Video Decoder). Check CPU usage. If it does not hit 100%, it's OK.

 

[Daventry]

With h.264 1280x720, a 1.8 GHz processor is adequate for most with older video cards. There are some encodes that require 2.0 GHz and then peg out the cpu because of things like frequent scene changes and diagonal panning. RAM above 256MB doesn't help.

Yeah I can't find MPCVideoDec.ax after install.

Explain more. Install what? How can't you find MPCVideoDec.ax? Did the file MPCVideoDec.ax disappear from the folder where it was originally located?

 

[blackmax2k1]

Media Player Classic HomeCinema

 

[renethx]

Installing MPC HomeCinema is unnecessary (unless you want to use the player itself). You need to download and register the file MPCVideoDec.ax to use MPC Video Decoder in Media Center.
