this may sound like a dumb question, but why would someone want to do this?

MHealy

Comment #47 from MHealy [Reply]

Media Center by itself includes almost no audio options. FFDShow allows up mixing stereo source to surround, channel swapping, an equalizer and really more options than I’ve even experimented with. It even allows for Winamp 2 DSPs to be used with Media Center.

I think the real question is why wouldn’t you? As Microsoft continues to ignore those of us that want more control over our media I’m sure more than a few reasons for using this hack will arise.

Comment #48 from Josh Pollard [Reply]

The audio from my analog tuners sounds a little muffled. Would this help?

MHealy

Comment #49 from MHealy [Reply]

It certainly could. FFDShow has a large number of options for enhancing audio output. Playing with the equalizer, crystality or some of the other settings could definetly improve sound quality. It’s subjective based on the user and hardware both so it will just take some playing around to find what sounds right to you.

Another codec I really like is ACFilter, which you can get at http://ac3filter.net/. AC3Filter is only for 32-bit however. If you use a 64-bit version of Media Center AC3Filter won’t work in most areas including live TV. FFDShow will work on both x32 and x64 with the right download package for your OS.

I’m running x64 Win 7. Have installed both the x32 and x64 versions of ffdshow. Is the CLSID the same for both the x32 and x64 versions of ffdshow? ie do x64 programs automatically use the x64 ffdshow if installed?

MHealy

Comment #51 from MHealy [Reply]

Yes, the CLSID is the same for both x64 and x86 versions of the codec and the correct version will be loaded by the program. For example, if your default Windows Media Player is set to x86 then your music will use the x86 codec but the live tv will use the x64 version.

Comment #52 from Paul [Reply]

I wonder if we could use this method to change the default video codec Media Centre uses.. I’d quite like to try Media Player Classic – HT’s codec.. It might be more stable decoding h264..

MHealy

Comment #53 from MHealy [Reply]

The problem with changing the default video codec is the new wtv file format used for live and recorded tv. You can use MPCVideoDec for videos and movies but using it for live and recorded tv results in an error when trying to view. It’s most likely intentional to keep control of DRM.

Thanks MHealy. So does that mean that we are stuck with the native video codec? Are there any methods currently available that will allow one to “upconvert” recorded shows in standard definition to higher quality? I was hoping to do this using ffdshow in combination with 7MC..

This registry edit “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\MediaCenter\Decoder” helped me setup ffdshow as the default decoder for MPEG-2 files. Thanks a lot

Is there a similar registry hack to set ffdshow as the default decoder for H.264/MPEG-4 files?

[My MPEG-4/H.264 files still don't use ffdshow even though I have set the ffdshow merit to highest.]

MHealy

Comment #58 from MHealy [Reply]

There are two files in the system folder that will over ride mpeg4 playback in some instances. You can rename them to disable them like with the mp3 decoder. They are named mp4sdecd.dll, mp43decd.dll and mpg4decd.dll.

Also, you can try using GraphStudio following this guide to determine what codec is interfering and lower the merit of the offending codec.

DTS in my DVD-audio plays fine now for the first time, thx a lot for showing me how to do it. But it seems like I can’t play FLAC audio files after making these changes (FLAC worked before the changes). Any ideas?

MHealy

Comment #42 from MHealy [Reply]

FLAC is disabled by default in FFDShow’s audio settings. Turn it on to libavcodec under the Codecs section of the FFDShow Audio decoder configuration program. That should get your FLAC files playing again.

I’ve done that but it still won’t play. In Media center’s music library I get this message “Audio error C00D11B1″. In Media browsers library I can’t see the audio files at all just the folders.

Comment #44 from MHealy [Reply]

Do you have other codecs or codec packs installed as well or just FFDShow? Other codec packs could be causing a conflict.

There is also a guide specifically for FLAC files in WMP/MC right here.

Comment #271 from stormking [Reply]

I have enabled FFDShow in Windows 7 MC x64, but I cannot play ALAC Apple Lossless Codec .m4a files in the Music Library.

I have done some research and, correct me if I’m wrong, FFDShow does not support ALAC and supposedly the only DirectShow filter that can decode ALAC is DC Bass Source Filter:
http://download.dsp-worx.de/DCBassSource_v1.11_Installer.zip

However, the instructions I have seen for using this filter do not assume you have implemented the directions above by making FFDShow the default audio filter for WMC. Thus, I believe I have DC Bass Source Filter installed, but I am assuming is not correctly being used because FFDShow is attempting and failing to decode the ALAC when I try to play the file (WMC says “the file you are trying to play is missing or corrupt” etc).

So, can someone offer a solution for playing back ALAC in WMC/7MC (x64) or hypothesize on how one may correctly enable FFDShow for decoding all audio of 7MC, EXCEPT for playing back .m4a ALAC files, which should be directed to the DC Bass Source Filter instead?

Thanks!

Michael Healy

@Reply #273 from Michael Healy [Reply]

I don’t have any ALAC files here to test on, where do you get them from (legally)? Are these the files distributed by the iTunes service? I’ll see about getting a hold of a few to play with.

stormking

@Reply #274 from stormking [Reply]

You can create a .m4a file containing an audio file compressed with ALAC by first editing your iTunes preferences:
Edit:Preferences:General:Import Settings:Import Using->Apple Lossless Encoder

Then put in a CD. A pop up box should ask you if you want to rip the cd. Say yes and it should use the settings you just edited. Alternatively, you can always right click an audio track and select “Create Apple Lossless Version”. Technically this only makes sense to do to a CD track, but you can convert a mp3 file (obviously won’t increase the quality of the track but for the purpose of testing .m4a/ALAC playback in 7MC, it doesn’t matter).

And, as a side note, after opting to go w/ ALAC for my music collection, I have converted my FLAC files to a .nrg CD Image file using Nero, mounted that CD .nrg file with Daemon Tools, and then ripped the new “virtual cd” from iTunes – who now looks at the bunch of original FLAC files as a real physical CD. Thus it rips it to ALAC losslessly and grabs all CD album info as it normally would with any cd. You could say it helps normalize a collection with both audio codec and CD Track/Album information.

Anyway, its done, but now I’d like to play it all back in 7MC, or I’m screwed and need to use 7MC + iTunes for playback.

BTW, I think DC Bass Source Filter is 32bit only as K-Lite Codec Tweak Tool shows the following for filter information:
.alac {ABE7B1D9-4B3E-4ACD-A0D1-92611D3A4492} DC-Bass Source [only valid for 32-bit]

7MC on x64 is 64bit so it appears that the only DirectShow ALAC filter I have found will not work on x64. I’ve taken this about as far as I know how. We need to figure out how to use DC Bass Source Filter in x64 or find a x64 ALAC filter that can coexist with FFDShow for .m4a/ALAC playback.

Thanks!

@Reply #275 from Michael Healy [Reply]

I ran a test and I was able to play an m4a file created in iTunes from both WMP and 7MC on an x64 Windows 7 build 7000 machine. I have both FFDShow Tryouts x32 and x64 installed and the AAC decoder is set to “libfaad2″ in FFDShow Audio Decoder Configuration.

I believe the latest Shark007 codec pack for Windows 7 supports m4a as well. I would try uninstalling other codec packs such as k-lite and use shark007 Windows 7 and Windows 7 x64 packs. Shark007 is the most preffered codec pack in the community for Media Center users and plays very well with almost all formats.

Let me know how you come out with it.

stormking

@Reply #276 from stormking [Reply]

Interesting. Thanks for checking. Could you please verify that the .m4a was encoded with ALAC? Because the .m4a container can handle AAC and ALAC encodings (basically compressed and uncompressed Apple audio). I’m not sure the FFDShow AAC options have any effect, as I’m learning ALAC is its own codec – separate from AAC. It would be nice if FFDShow implemented ALAC support (its on their list). libavcodec already supports ALAC and FFDShow uses libavcodec, so I’m not sure what the hold up is. VLC uses libavcodec and I can play ALAC .m4a files in VLC.

I have been looking at and did install Shark007. Where this will help is that it includes the DC BASS Source Filter mentioned above. From my endless googling, it appears its the only DirectShow ALAC filter for windows. So, I suspect that if in fact your .m4a is ALAC not AAC, then you are getting ALAC decoding in WMP/7MC from DC BASS included with Shark007. Before installing Shark007, I had just installed DC BASS individually.

I’ll try to reinstall my codecs and see if that helps. I do wonder though if Windows 7 x64 can use 32bit filters as DC BASS is 32bit. I know x64 can exec 32bit apps. Does the same apply for filters – and even drivers?

stormking

@Reply #278 from stormking [Reply]

Reinstalling the codecs didn’t help. If you have an ALAC .m4a then the only difference would be the beta versions of Windows 7. I did hear of new trouble with beta 7057 with FFDShow video (couldn’t get that to work). I don’t know if there is a difference here in getting ALAC to work on Windows 7 x64 7057 versus 7000. But Windows 7 x86/x64 RC should hit the street any day so it would be good to standardize configurations on that.

stormking

@Reply #281 from stormking [Reply]

Ok. I have answers. I have ALAC (Apple Lossless Codec) .m4a files working in Windows 7 Beta 7057 x64 Media Center and in WMP.

FINALLY, after hours of trial and error and googling to the ends to the Internet… googling “directshow 32bit 64bit filter” found RiverPast Quicktime DirectShow Filter which for free (!) will enable ALAC in 7MC x64!

http://www.riverpast.com/en/prod/quicktime/

Here is the interesting thing that I noticed though. Although I never installed K-Lite Codec Package, I did install their K-Lite Codec Tweak Tool:
http://majorgeeks.com/K-Lite_Codec_Tweak_Tool_d5738.html

Running this tool and checking (under Generate text file containing) “A list of all installed DirectShow filters” and “A list of all installed DirectShow filters (64-bit)”

yielded a file containing the following line:
.alac {ABE7B1D9-4B3E-4ACD-A0D1-92611D3A4492} DC-Bass Source [only valid for 32-bit]

After installing the RiverPast Quicktime DirectShow Filter and re-running the K-Lite Codec Tweak Tool yielded a similar text file but with an added entry for .m4a:
.alac {ABE7B1D9-4B3E-4ACD-A0D1-92611D3A4492} DC-Bass Source [only valid for 32-bit]
…
.m4a {64C6BF57-2D38-4d10-A1DF-330AD98CD4C2} QuickTime Decoder [only valid for 32-bit]

which tells me the following. Despite having the DC BASS Source Filter installed (which is included with Shark007) it was not properly registered with .m4a extensions. The problem wasn’t that DC BASS Source Filter is 32bit and I’m running x64, it was that the filter wasn’t registered correctly. It appeared that .alac sounded like a good extension for DC BASS to be associated with but ALAC is the codec not the container. The Shark007 developer might want to look at this and tweak the install or perhaps use RiverPast Quicktime instead of DC BASS in Shark007.

Having said this, one complaint thus far, playback of .m4a ALAC in 7MC x64 is not gapless playback. So you hear the pause between tracks. Well, at least it plays them.

Michael Healy

@Reply #286 from Michael Healy [Reply]

After double-checking this morning you are correct, it had converted to AAC not ALAC. When I created an ALAC file it wouldn’t play using FFDShow. It seems that the only solution may be to wait for an ALAC capable codec to be released. If you don’t mind me asking, why did you choose the ALAC format over FLAC?

stormking

@Reply #295 from stormking [Reply]

So it turns out that I can only play ALAC in 7MC after first running WMP, playing a ALAC track and then starting 7MC. Is there a reg hack to make 7MC see .m4a as a valid extension? .m4a is listed in the WMPlayer registry so I assume that’s why its working in WMP. Wondering what I can do so I don’t have to bootstrap 7MC by first playing WMP.

stormking

@Reply #296 from stormking [Reply]

Actually just figured out this is because the DirectShow filter is 32bit and 7MC is x64. Reviewing my running processes, you can see that my default WMP is 32bit, so when I run WMP (when 7MC is not running) I can play ALAC because the player and filter are both 32bit. When I run 7MC without running WMP first, wmplayer.exe (64bit) execs and will not play ALAC as there is no 64bit DirectShow ALAC filter. So, off to look for a 64bit Quicktime DirectShow filter or find a way to force 7MC to use 32bit wmplayer.exe (*32).

Btw, here is another Quicktime DirectShow filter:
http://www.medialooks.com/produ…rs/quicktime_filter.html

Both of these filters also takeover decoding .mov files. I played back the new Terminator 1080p trailer (.mov) at 6-8% cpu usage since the DirectShow was uses my video card (3.33Ghz dual core, ATI 4800 video card). Playing this trailer on Quicktime used 35% cpu usage.

After much frustration… I found that renaming the MP3DMOD.dll actually caused issues with me playing any avi, xvid, divx, etc videos. Plus the sound on my LiveTV playback works perfectly. What is the significance of my findings?

Are the videos i am playing still using the FFDShow audio or MS’s native audio codec? (Note: the default audio decode is set to FFDShow Audio Decoder CLSID)

How come my Media Center successfully uses FFDShow audio on live tv playback without having to rename MP3DMOD.dll?

There are a few videos that use the AC3 codec i am unable to play. When i enable AC3 pass through on the FFDShow audio settings however, it crashes tv playback with a decoder error… How can i also get these movies that are encoded in AC3 audio decoder to play?

Instead of settings FFDShow to pass through AC3 audio you should try changing AC3 to libavcodec under the Codecs settings tab.

The AC3 decoder is set to libavcodec but still doesnt work. When i play thru Graphstudio it works, but not thru Media Player. I did notice that when i play thru Media player the icons for FFDSHOW video and audio do not appear in the taskbar.

I currently followed the guide to set powerdvd9 to the preferred video decoder in the registry and did set the CLSID of ffdshow audio as the preferred audeio decoder. I then used the preferred dshow filters tool. Anything that i missed>?

ssalsekki

Comment #1797 from ssalsekki [Reply]

i want to add that when i play mkv files the ffdshow decoders load properly and works fine.
However, avi files do work fine but do not load up the ffdshow decoders which makes me wonder which decoders they are using since the native M$ dts/dvd decoder has been manually changed to powerdvd9.
When i load up avi in graphedit it shows it is splitting it out to ffdshow video/audio…

ssalsekki

Comment #1798 from ssalsekki [Reply]

Sorry i want to correct my last two posts. Only avi files with 2 channel stereo play although they dont seem to user the ffdshow decoders. When i play thru graphstudio they work thru the ffdshow decoders just fine, meaning they are using the m$ native decoders. I manually did the reg fix to set the preferred decoders to ffdshow for audio and cyberdvd9 for videos. I properly set the merits for ffdshow to highest using radlight filter mgr.

So my guess is that the reason it doesnt play 6 channel AC3 avis is because it is still trying to use m$ native decoders. I also used MCDU and Preferred Filters tool and they didnt work. Any suggesstions on how to ensure Media Center/Player will use FFDSHOw video/audio?

ssalsekki

Comment #1799 from ssalsekki [Reply]

Ignore my last posts. Here is the core cause of the problem. Media Center/Player uses native m$ codecs instead of ffdshow for the video and audio decoding on movies and clips. (It works perfectly on Live TV playback however ).

I followed the guides:
- Disable and Replace MS-DTV/DVD Decoder
- MKV for Minimalists(using Haali instead)
- ffdshow video/audio for Media Center

Tried the following tools:
- MCDU
- Preferred Direct Show Filters Tool

So as of right now live tv playback is working beautifully in Media Center. But i cannot play any movies because it then tries to use M$ native decoders instead.

Please help, been working on this for two weeks now…

Michael Healy

@Reply #1804 from Michael Healy [Reply]

OK, Preferred DS Filters Tool should be redirecting the default MS decoders but since it isn’t let’s try and track them down and simply rename them.

Check the encoding being used in one of the movies that isn’t playing properly using MediaInfo.

Then either check inside system32 and syswow64 for the dll decoders for those filetypes or post the encoding here and I’ll have a look.

ssalsekki

Comment #1805 from ssalsekki [Reply]

I am on 32-bit windows 7 build 7201 so there is no syswo64 dir right?

- Annie.avi
video: MPEG-4 Visual (XviD)
audio: MPEG Audio (MP3)
My thoughts:
– the native M$ MP3 Decoder DMO should have been disabled by renaming MP3DMOD.dll correct?
– found that qasf.dll is M$’s native MPEG-4 decoder and renamed it, no luck

Notes: When i open Annie.avi thru GraphStudio it properly splits out to FFDSHOW for video and audio and i am able to play it as well.

stormking

Comment #2301 from stormking [Reply]

In following up with my previous post on how to get ALAC to work in Windows 7 Media Center x64 (7201), if you install this Quicktime DirectShow Filter and then with Shark007 x64 Settings Application, set the default Windows Media Player to 32bit, it will work.

http://www.riverpast.com/en/prod/quicktime/download/

If you look at your processes, you will see wmplayer.exe*32 running while playing a .m4a ALAC (Apple Lossless). This will enable the 32bit decoder above. Interestingly enough, this does not mean that .mkv files will playback with 32bit FFDShow (I don’t even have the 32bit FFDShow installed). Even with the Windows Media Player default set to 32bit, the splitter splits the video/audio streams to 64bit FFDShow Filters. So setting Windows Media Player to default to the 32bit player instead of the 64bit player will not foobar your other 64bit filter settings.

A downside though is that Media Center still will not see the album art work for .m4a ALAC files – although Music Browser can show the art work.

Only files that have mpga audio are affected.

Any update on what’s causing this? I have tried to use the Preferred DS Filters Tool but this has no effect.

I am using shark 007 codecs as well but this shouldn’t effect it as I can edit the FFDShow settings independently.

When I rename the MP3MOD.DLL back to its original, sound does not return for the affected files.

Would certainly appreciate some help on this.

It works better with the decoder set to AC3filter, but still cannot play avi files. Any work arounds you know of?

Does this work in RTM. I am running Win7 Pro and if I chnage audio decoder to ffdshow, 7mc can’t play xvid files. Surprisingly sample video included with 7mc runs fine.

If I reset to MS codec, everything starts working again.

My reason to set ffdshow as audio decoder to be able to play dts wav file which also does not work. So I assume somehow W7 RTM is not allowing something which was allowed earler (No problem with ffdshow+dts in XP)

Comment #3745 from Sakura [Reply]

I have installed the latest Codec Pack (CCCP with Win7 support) and everything works nice together with ZoomPlayer Max 6.0 (yes i use this rather than the WinMC). FFDShow kicks in for anything but 48khz MP3s. Only these.
So I tried the above Method and noticed some strange behavior (on Win7 Prof. x64 RTM).

Only renaming the DLL in the SysWOW64 path does effect the playback at all.
After renaming it ZoomPlayer runs fine with FFDShow for all Files. Media Center runs with an internal Codec and don’t use FFDShow at all. Not even CoreAVC ~.~
MediaPlayer 32bit leaves me with FFDShow and scrambled sound (only with the 48khz MP3 Audio – others work).
MediaPlayer 64bit runs with FFDShow and good Sound.

This is all confusing since I didn’t touch the 32bit decoder residing in /system32/ (for the testing)

On my MediaPC I will still reside with XP since it’s easiest to set up for my needs.
You may ask why I use FFDShow. I use the AC3 SPDIF upsampling since my Amp only has a coax digital Input and no 5.1 cinch input. (and I like the LFE Crossover features in FFDShow)

Unfortunately this does not work on Windows 7 RTM x64/x86 for me. I have tried changing the CLSID in the registry but Media Center and Media Player still don’t use ffdshow audio decoder. The reason I want to use ffdshow audio decoder is, because I want to watch Blu-Ray. H.264 video plays fine, but I can’t hear any DTS or Dolby Digital sound. I also tried the same with AC3Filter, but that doesn’t work also.

Is there anything else I can try to make Media Center/Player use ffdshow audio decoder?

Ok for the people experiencing problems with xvids not playing after this I have just got mine to work.

My setup:

Windows 7 32bit
SPDIF Audio out to amp
Shark007’s codec pack

1. Uninstall all codec packs and media center.

2. Make sure MP3DMOD.DLL is just that and not the renamed backup – then reboot.

2. Reinstall Media Center

3. Make sure your videos now play – if they don’t you have bigger problems

4. Install Shark007’s Codec pack found here: http://shark007.net/

5. In the ‘audio’ tab, panel make sure FFDSHOW SPDIF Passthough is ticked and select your speaker setup on the left (carefull as this will reset the spdif passthrough options on the right)

6. Using regedit and the instructions in the original post, change the CSLID of the default Windows Media Center to FDSHOW’s CSLID

7. DO NOT CHANGE THE MP3DMOD.DLL ! (this is what caused my problems apparently as leaving it alone gave me the correct results)

8. Open the FFDSHOW Audio Decoder Options (through Shark007’s settings utility under the ‘config’ tab

9. Set the following options:
- in ‘codecs’ mp1/mp2 as libavcodec
- mp3 as libmad

10. Restart media center and that should be it.

Not sure if I still have FFDSHOW for TV audio as I haven’t checked yet but my films work with FFDSHOW audio now.

I hope this helps somebody as my problem is sorted… for now

Ok so I changed the MP3DMOD.dll to MP3DMOD.dll.bac

I don’t know what was causing the problems.

TV doesn’t have FFDSHOW but that’s fine by me as all the important stuff does.

In the words of a great philosopher – “meh”

Turns out I didn’t change the CSLIDs so I guess that was the fix for me.
