Hello
I've been searching the net to address the No audio compressor could be found to decompress source error tag 00ff.
Note: I'm not trying to compress the audio at all, that is turned off. All I'm trying to do is convert it to mono as it's coming out the right speaker. In the audio menu, under conversion setting there is an option for Mono but I keep getting this error. I've tried to install ffshow, and many others recommendations. I don't know what I'm doing wrong.
The original Mp4 video came from my Samson phone. The audio appears to be an:
MPEG-AAC (mp4a) 48000Hz Stereo (but audio only comes out right side). I can't seem to export the audio to an external editor either way because I get the decompression error for that also.
The video by the way is an:
H264 - MPEG 4 AVC (part10) (avc1) Decoded format: Planar 4:2:0 YUV.
Not sure if this matters or not.
Any recommendations to fix this would be hugely appreciated.
Thank you. |

Go to sourceforge.net/projects/fcchandler and get the AacAcm Codec
(I *think* that's the right one) |

Hello raffriff42, thank you for your response.
I have a file that I already tried yesterday titled: AC3ACM22 AC3ACM v2.2 by fccHandler. I think it's the same thing as you recommended, just newer as your file is 1.9. Or no? I ran the bat file as an Administrator and I got a CMD window. All it did was add an AC-3 ACM Codec and AC-3 ACM Extensible under the compression settings, but I still get the, "No audio compressor could be found to decompress source" error. Originally I was going to compress it as MPEG Layer-3, but at this point I would be happy to just leave the audio as: <No compression (PCM)> since the 320p video was around one MBs without compressing the audio.
I just need to make the stereo mono as it's only showing one source track. Is there a way to just copy the one source track and make a second track in VertualDub?
EDIT
I think I might have wrapped this up.
I ended up opining the Mp4 in Avidemux2.6 and it turns out the ACC audio "was" coming out of both speakers. So I just made my moving length edits in Avidemux, saved out in the same Mp4 format and then converted from Mp4 to AVI in VirtualDub leaving the audio unprocessed/ untouched. It came out looking good. Had a few other people play the video and it works well for them also, so I guess that's good.
This VertualDub is a great program, I think I'm going to be using it often! Though I have so much to learn about the rules. I didn't like the sound of the Mp3 encoder when I converted from ACC in Avidemux, so that's why I left it untouched and I also did the same in VirtualDub. It makes sense why it sounded bad as ACC is lossy and going to Mp3 is compressing it twice which is never good. |

I suppose you are confusing the AC3 (tag fffe) audio-codec with the AAC audio-codec (tag 00ff). These two are NOT the same.
So follow carefully what raffriff42 was telling you ...
Download the "aacacm v1.9.zip" and open it with Windows Explorer or with an unzip-program.
You will see two ranges of files: one for 32-bits (in folder x86) and one for 64-bits (in folder x64).
You must use the files that correspond to the xx-bit version of VirtualDub that you have installed.
Try to install the AAC audio-codec by a right-click onto the *.inf and click onto Install, OR by a double-click on the *.bat file.
Once you were able to install this AAC audio-codec, your "decompressor" problem in VirtualDub must be gone.
In VirtualDub, via the Audio-menu and then clicking Conversion..., you must be able to double the single audio-track (mono) to a double track (stereo).
Set the Audio-menu to "Full processing mode" and (also in the Audio-menu) select via "Compression..." an audio-codec.
If the orginal file is an AVI, then you can set the Video-menu to "Direct stream copy" (so NO re-compression of the video-part will be done, just recompression of the audio-part).
If it is not an AVI, then set the Video-menu to "Full processing mode" and select via "Compression..." a video-codec.
File > Save as AVI... to create a new file.
Good luck. |

Can use Fcchandlers Quicktime decoder to also Direct Copy AAC audio with virtualdub
http://sourceforge.net/projects/fcchandler...ktime%20Plugin/

Hello Abrazo
As far as the tags, I was just reading what the error said. I don't know what the tags even pertain to (something I need to investigate further). I had three questions in response to what you said above please.
1. I'm curious though, can you have both 32 and 64 bit versions for the same codec installed on the same system? The reason I ask is, the latest VertualDub I have v1.10.4 is 32-bit client. However my Avidemux software is a 64-bit program. What do you do if say one of your video programs needs a 64-bit plugin and another program needs a 32-bit version of the [u]same plugin?
2. Something I have to point out also. When I right click the bat file for aacacm v1.9, the black CMD window comes up and all I can do is hold the enter key to make the license text scroll down. But when the text gets the bottom of the window, two other CMD windows pop up on my screen with the same license. It looks as though the bat file wants to install the same thing two more times. What is the deal with that? Nothing in the readme file says anything about it.
3. Also, how would one go about manually removing codecs? Say your windows installer got corrupted? Is there a specific location in windowsXP, 7, and 8 that these get stored. Are there registry keys added also?[B]
Running Windows 7-64-bit spk 1 by the way |

These "tags" are simply a four character code that identify the audio-codec that has been used to encode the audio.
Via Windows Media Player > Help > About Windows Media Player > Technical support information > at Audio Codecs, in the column "Format" you can see the tags for the decoders that are available/installed on your computer.
1. Yes you can have both versions installed on the same system.
2. dloneranger has made an installer for the AAC audio codec that you can find here:
> http://sourceforge.net/projects/fcchandler/files/
> the name of the file to download is "SetupAACacm_X86_X64.zip"
3. Windows 7 (32-bit) registry keys that contain the audio codec info:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]
"msacm.aacacm"="AACACM.acm"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\drivers.desc]
"AACACM.acm"="AAC ACM Codec"
On my Windows 7 32-bit computer, the AACACM.acm file is in C:\Windows\System32 |
