How to stop using WMVideo decoder DMO?
For some reason in the last few weeks my PC has started using the 'WMVideo decoder DMO' for all wmv links - this bloated codec hogs all my CPU power, but I can't seem to make these codecs go away. And it seems like those are essential codecs, why would they suddenly start using 40-50% CPU for small WMV clips? Any tips any one?
I use MPC and ffdshow - you'll have to pry ffdShow out of my cold dead hands I fear so I can't give that up. I like to have many video windows going at once so CPU is important. This is a new thing (this intensive CPU usage) I have recently gotten a new Video Card ge force 7900 GTX) and started running in renderless mode VRM9 Bilinear (PS 2.2.0) |

What WMP version do you have installed? |

I have WMP 10 I think, it's been so long since I used it. In order to use virtualdub with wmv files I had to d/l some MS encode pack I think, but I uninstalled it trying to solve my problem.
I understand that WMV 9 will be played by this new codec, (MS' heavy handed big stupid way to handle high res) but the problem is every wmv or avi file has been taken over by this codec |

Please try doing this: 1. Download WMP10 from here and reinstall it again. 2. Download WMV9 VCM from here and install it again. 3. Verify Ffdshow is configured only to handle non-Microsoft codecs. It's best to let WM codecs handle WMV decoding and doing this will avoid unnecessary conflicts. Quote:
If the WMV Decoder DMO is getting inserted into every decoding graph, clearly something is incorrectly registered on your system. WMV decoder can only register itself to handle a handful of WM codecs - and reinstalling WMP should take care of that. |

I did that, and thank you for those tips. As often happens with these kind of threads you don't know what to say to explain your problem in a concise way - but often after a few responses it becomes clearer. So . . .
The new wmv decoders (WMVideo decoder DMO) are too processor intensive. Video clips that used to use 4% CPU now require 30% CPU - the same wmv file. I want to go back to the older wmv decoders and not use the newer ones at all. (except on WMV 9 files) |

Since I guess I am barking up the wrong tree I will keep on looking, now I'm thinking it's the color space I have been using. (YV12)
I come from the pro audio world, this stuff is a lot harder. And trying to learn on forums is difficult. |

getting closer
I'm getting closer to my goal/fix. I unregistered the dll's (maybe wmvdmod.dll) and the audio one as well, checked the merits of lots of things. But even if I up the merit on quartz.dll the other direct x object still is favored (WMvideo decoder DMO). Maybe because I have Microsoft .NET Framework installed? Anyway, a lot of things became clear to me.
Dude! Why didn't anyone tell me you had to manually add the codecs and filters into mediaplayerc? (external filters) I thought it used magic. Haha - I will have to change my user name now, I have been using the k-lite pack for at least 2 years. So it was a user issue after all. |

The average user really doesn't need much more beyond MPEG-2, Ffdshow and possibly CoreAVC decoders installed these days. WM codecs are already preinstalled, so they're covered. Installing some shady codec pack is really not necessary, and IMHO, often has dire consequences. |

I happened to need just a small fraction from codec packs. I didn't had problems with filter merits neither. I think they are useful for people not being connected to Inet at home - just download the pack and get all you need for playing video content. But I agree on that it often has bad impact - if the user installs everything that's in the pack . Btw. I'm way off-topic, sorry.

I think the K-lite pack is great - it's on a different level from the average codec pack - mostly because of the codec tweak program. It doesn't dump a ton of sh1t on your PC like any Sony/Sonic product does, or ATI - god almighty the useless codecs they cursed me with.
Most people, even computer savvy people, have troubles understanding the codec issue and k-lite is a great way to get your files running fast. |

If I take a problematic file and render it using GraphEdit (which uses active movie - man I wish I could use that as a player) the file only uses 3% CPU. Is there a way to rework the file using the pins I want? I.E. I get it working in GraphEdit but I can only play that file through GraphEdit, how can I save the file to use in MPC, or re render it using the filters I desire? Is that what changing the 4CC thing is about?
myfile.wmv < --- >WMVideo Decoder DMO < --- > Video Renderer Using any of my 4 players (MPC, ZOOM, Elecard, WMP) results in 30-40 CPU usage, with Media Player Classic having the worst performance (that shocked me) and Windows Media Player 11 having the best (also a shock) Then I went into my BIOS and changed the hyper-threading to "on" and I got it down to 15=20% CPU usage and I'm giving up here. So I guess when it comes to video the PC uses both processors. Last edited by mike_lee; 27th May 2006 at 06:21. |
