"No Compatible ACM codec..." error?

[hazel-ra]

I'm trying to use a .wav I ripped from CDex in a script with the audiodub() command. When I play the file, I get the error "No compatible codec to decode 0x2000 audio stream to PCM" . I haven't found a fix or explanation with some googling. What's going on here?

I did find this thread

Wherein the author says they found the answer using the search function, but alas, for me the search only turns up the above linked post.

Any chance the CD in question was an AC3 CD?

Load it up with VLC and see what the Codec Details page (CTRL+J) tells you about the data.

Codec: araw -- is that what you're asking for? The rest is:
Type: Audio
Channels: Stereo
Samplerate: 44100 Hz
Bits per sample: 16

Is there another program I could load the file in to render to wav of a different kind? I tried audacity, but it's the same deal.

0x2000 = AC3

Ha! How silly of me. This is a problem with my video, not the wave file I'm trying to use.

I'm still confused, though. I can watch the .avi files in any of the video players I have. I installed the AC3 codec, the CCCP or whatever it's called, and also the lame codec. Yet still I can't watch my scripts. WTF, man, WTF?

WAVSource uses ACM - which is kind of the audio analog to VFW.

Media players usually use DirectShow, which is totally independent from VFW/ACM.

Separate also are apps like VLC, which don't rely on DirectShow or VFW, and have their own internal libavcodec.

You can try to convert the SPDIF-wrapped AC3 streams to pure AC3 files by using the command-line application bsconvert.exe (part of the AC3Filter Tools). I don't know if eac3to can do that too.

P.S.: You could also give a try to the AC3Filter ACM codec,
perhaps it's able to detect AC3/DTS in spdif .WAVs.

P.P.S.: Please ignore what was written above. It seems the AC3Filter Tools do NOT work correctly for non-48kHz stuff. :( :eek: :mad:

I re-encoded my vob sources to use mp3 CBR. That works around the issue, at least.
