Virtualdub or AC-3 Decompressor not working w/ Windows 7???

[jwmghf]

Hey guys:

I can't get Virtualdub to work in harmony with AC-3 Decompressor and Windows 7 64-bit? Windows 7 says it doesn't see a decompressor source. Is there a workaround for this?? Possibly another decompressor program???

Thanks

maybe you could try ffdshow (there are also 64 bit versions but 32 runs fine) for the ac3 decoding job under win7/64

I tried FFDShow and Xvid but virtualdub says it cant find the ac-3 decompressor. So I don't think that AC-3 Decompressor program is actually loading up. When I right click on the AC3ACM and hit the install, I do see the cmd box open momentarily and then close, so I don't know??? Is there a different compressor program??

Thanks

WHEN does vd say so / trying which operation?

i downloaded a vd_64 bit version this minute and loaded an avi file which has ac3 in it and when loading the file file MY version does not complain using win7/64

i have ffdshow(64bit) installed and checked that its internal audo config showed that ac3 was handled

[UncasMS]

ok, i think i now see what your problem is

when trying to save this file i opened vd complained

i installed this ac3 filter and was able to decode

Here is what the error says exactly:

Couldn't locate decompressor for format 'XVID" (unknown)

VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Player, are not suitable.


This error comes up after I have loaded the avi, and do all the steps I would normally do to create a wav file for input to T<PGEnc 2.5. When I hit Save Wave and name the file, the program normally takes off at this point. That's when I get this error. I loaded up VirtualDub 64 and FFDShhow 64. Still the same problem??? What do you think?

[UncasMS]

did you see my second reply above yours?

so now we also have trouble decoding the video as well???

hmm, no such trouble here

try ffdshow pls it should really do the job

[UncasMS]

shark007's win 7 filters may also be worth a closer look

[jwmghf]

I'm still having the same problems. Now I get that error as soon as I load the avi. I am going to try another avi with ac-3. Windows media player won't open it up either. But media player classic will? I will do a full uninstall and re-install and post back a little later. I am frustrated!!! Thanks for helping me out.

[UncasMS]

so far i have no such problems here

installed media playere classic home cinema 64bit, ffdshow (32+64) and the said vd 64 version and playing as well as opening/saving via vd works

good luck

Thanks man:

I will post back and let you know how I make out. Enjoy the rest of your weekend!!!

Hi guys... I wonder if anyone can help. I have windows 7 x64 here, and installed FFDShow x86 and x64. I also installed Haali Media Splitter cause I needed it for SubtitleWorkshop to work. Now I've installed VirtualDub x64 and i get the "no audio decompressor could be found to decompress the source audio format" when trying to play an avi with AC3 audio. I do not want to install another codec, i would like it to work with FFDShow, which does play fine in MPC and other apps. Any help?

EDIT: I can work with AVIs with, say, MP3 audio. But the FFDShow icons don't appear. That means VirtualDub isn't using FFDShow, right?

i have linked to the ac3 codec provided by alexander vogovsky, who knows his stuff for years

give it a go

[jwmghf]

I think the problem is that the ac-3 decompression program is not loading up properly. dronkit, after you install it go to add/remove and remove it. I bet it tells you that there's a problem and the program looks like it has been uninstalled already. That's what I'm getting... and it's really aggravating!!! Hopefully, it can be fixed.

jwmghf, are you saying that the ac3 filter from alexander vigovsky does NOT work for you?
