| Unofficial VirtualDub Support Forums > Codec Discussion > Vbr And Audio Codec Problem |
| Posted by: airdave Aug 7 2007, 01:54 PM |
| Sorry, looked for an answer before posting this but haven't found what I need... I use Vdub for a number of video issues, most often to adjust volume levels. Past experience with VBR has been: load the file, adjust the volume, save as AVI and sometimes (not all the time) experience an audio synch problem. In that case, I just live with the file I have. But now, all of a sudden, any VBR file that I try to alter will not save...I get this error: "Error initializing audio stream decompression. No installed audio codec could be found to decompress the compressed source audio. Check to make sure you have the required codec." (For volume adjust, I run Direct Stream Video and Full Process Audio. and I "save as AVI" regardless of size) I have used GSpot to verify that the required codecs ARE in fact installed and of course the file(s) plays perfectly in a number of different players. I have removed Vdub and re-installed latest version - no change. What has changed for me? Do I really have the correct audio codecs? or is there something wrong with Vdub? thanks in advance for any assistance! |

| What is the audio codec identified as? |
| Posted by: airdave Aug 8 2007, 01:18 PM |
| I sampled 6 videos that will not "save" with GSpot (because of this issue) and here are the audio codec infos: 0x0055 MPEG-1 Layer 3 - 48000Hz 128 kb/s tot , Joint Stereo 0x0055 MPEG-1 Layer 3 - 48000Hz 125 kb/s tot , Joint Stereo LAME3.90. 0x0055 MPEG-1 Layer 3 - 48000Hz 126 kb/s tot , Joint Stereo LAME3.96r |

| When you open the video in Virtualdub, can you post a screenshot of File menu > Information? Also, when you select the audio codecs what does it show for the MP3 codec? |

| First off, you cannot adjust audio levels in Virtualdub. You need and audio editor to do this. Second, if you don't save the VBR audio as an uncompressed wave with Virtualdub first, it will be out of sync every time. I use Goldwave to open the AVI (audio), adjust the volume, save as 16bit wave file and put that file back in the avi with VDub. In GSpot, under MS A/V at the bottom, click 1 to see what is decompressing the audio. You will probably get an error there. The Lame codec is not a decompressor. It's an encoder. Download the Fraunhofer mp3 audio decoder... http://www.free-codecs.com/download/MPEG_Layer_3_Codec.htm |

| foxidrive - I will get that screenshot up asap as far as codecs go...I don't usually choose a codec. I am making minor alterations before I burn a file to DVD (maybe I just want to up the audio level a bit) I save as AVI...and apply no compressions. (The file size is unimportant because I will burn it and then delete it) - in response to the last comments... I have been using Vdub to adjust audio levels on hundreds of files, for over 2 years! Choose Audio full, Volume, and adjust the volume level to the desired amount. And as for VBR files, no...not every one has a synch problem when resaved. It has always been hit and miss, some work, some don't. Fraunhofer....already got |

| Thanks. You would generally select an audio codec, and adjust its settings, to cement the audio format in place when converting volume. If you do not have an MP3 audio codec listed then install the LAME codec. |

| I am sorry...I do not understand what you are telling me to do? As I have always done, I rag and drop a video file into VirtualDub The window opens and I can start viewing the file if I wanted to (usually I don't bother, unless I am attempting to adjust contrast, sharpness, etc or maybe join split files together) If all I am trying to do is bump up the volume a little, I choose "Video - Direct" and "Audio - Full" Then I click "Volume", set the volume level and then I choose "Save as AVI" (I never bother with any compressions for Audio or Video) The newly saved file is sometimes quite large, but is burned to DVD and then deleted. When would I be choosing a video or audio codec and why? If the file opens and plays (in any program) then does that not mean the correct decompressing codec is being used?? So why can't Vdub save the file? Or are you just referring to the process of avoiding synch errors with VBR files? |
| Posted by: foxidrive Aug 9 2007, 01:21 PM |
| People usually use compressed formats to keep the filesize down... which is why and when you use video and audio compression codecs. I can't help with the error though, sorry. |

| The file that you posted the AVI Information for - is it one that works or doesn't work? Post the information from the same file you used earlier for the error message. I would also suggest updating virtualdub to version 1.7.2. |

Well I'll be danged. I've been using Virtualdub for over seven years and never knew that there was a volume adjuster. Thanks. I guess I've never had to change the volume of an AVI. Most of the files that I work on were done correctly the first time. As for VBR, it is enough of a problem to not even chance doing with Virtualdub. VirtualdubMod might work or Avidemux will usually fix the problem. It's quick enough to just save the wave and recompress it though. If you want to defend VBR as a viable option for AVI in this forum, you will get no support though. As for the problem that you posted "error initializing audio stream decompression", did you click on the 1 under MS A/V in GSpot? It will tell you what is trying to decompress the file and if it did or why it didnt work. If you do have the codec installed and it is working then if you click 2, the video should play in the built-in player and you should hear the audio. Just having the codec may not be the answer if it is not registered or something else may be installed thet is over riding the decompressor. It's strange that you have been decompressing these files for over two years but all of a sudden they stopped. Anything is possible with MS though. |

| yeah....seems like everytime you get a new version or update of one program, another program starts having problems. we tend to forget how even the most distant relate programs may share similar features or components. I like the theory that some other program has overridden or altered my Vdub. and hey, I didn't create the files with VBR and don't completely understand the pros or cons... I believe everything I have shown so far has been from the same movie file. |

It's not. The File Information screenshot shows a different number of frames than the gspot or virtualdub error screenshot. |
| Posted by: airdave Aug 12 2007, 01:56 PM |
| so...why are people using the VBR if its so problematic?? funny thing... moments after reading the last post, I had another (new) VBR file that needed a volume boost. Opened it in Virtual Dub, opted for Direct Video/Full Audio, adjusted the volume level and saved as AVI (file size went from 700mb to 1.6GB ...no error message and the audio stay synched perfectly! I burned and watched the DVD last night, no problems. anyway, DarrellS going back to the file I have used as a test subject up to now (which is a VBR file, the "file info" screen applies to this file) Squid is correct, the first 2 screenshots are from a different file. The second two screenshots are from the file I am using now (to test). I clicked on the 1 (below MS A/V) and codecs were listed, then I clicked on the 2 and rendered the file. It played audio and video...so as I said, I must have the correct codecs. so why then does it claim it can't decompress as soon as I try to save as AVI???? |

| If Virtualdub won't open it but will open all the others then what can we tell you except to use a different program to fix the file. A screenshot of GSpot doing what I asked would've been helpfull but it looks like we're not getting anywhere here. You've stated that you don't care if you get sync problems so why should you care if you've got audio at all. I think I mentioned both AVIDEMUX instead of Virtualdub or using Virtualdub with Goldwave to fix your audio problems but you have your own way of fixing your problems. Not sure what else that I can suggest. You could try using VirtualdubMod and demuxing the audio and then open the MP3 in Audacity (if you don't have or want to invest in Goldawave, it's free) and either compress to CBR MP3 or leave it as uncompressed wave like you've been doing and reinsert in with VirtualdubMod. I'm surprised that after 5 days that you haven't been able to fix the file. I would've just deleted it by now. Easy come, easy go. There are other forums like videohelp.com if you can't find the answer you're looking for over here. Most people here use Virtualdub for more than just adjusting the audio in all the VBR AVI files that they've downloaded from file sharing networks. |

| You may have a DirectShow decoder, but you're missing an Audio Compression Manager (ACM) codec that can handle the MP3 stream, or somehow the default one in Windows has gotten lost. I doubt VBR is the problem here. What's more likely the case is that there is something about the audio format that the Fraunhofer codec doesn't like. You can try this version and see if it can auto-fix the format: http://www.virtualdub.org/beta/VirtualDub-1.7.3-test4.zip Otherwise, please use the "create sparse AVI file" option on the tools menu, zip it up, and send me the header -- I can probably figure out why the Fraunhofer codec won't load the file. (There is no audio or video data included in such a dump.) DirectShow decoders tend to be very lax about validation, so sometimes files slip through that have partially incorrect audio format headers. |

A screenshot of GSpot doing what I asked would've been helpfull but it looks like we're not getting anywhere here. -sorry...obviously I missed something, and I need to go back and see what you asked for amid all this information. You've stated that you don't care if you get sync problems so why should you care if you've got audio at all. -don't care about synch problems? Why would I not care? I think I stated that I take a chance when modifying VBR files. It takes about 2 minutes to process the files and sometimes it works, if not I throw the file away! What a ridiculous comment to make. I think I mentioned both AVIDEMUX instead of Virtualdub or using Virtualdub with Goldwave to fix your audio problems but you have your own way of fixing your problems.

Got more things on my plate than just this video problem! -I have nothing I need to delete...got a good working video file. Sometimes I like to play with these files and adjust the screen res, or adjust the contrast or sharpness, repair synch errors, join multi part files together AND adjust audio levels. -I do not use any "file sharing networks". -sorry if I have wasted YOUR time, are you suggesting I leave and go to videohelp.com? Obviously I have irritated you (Darrell) in some way and I am not sure why. It was not my intention to bother you or upset you and I apologize for any insult I may have offered. I don't know you, have nothing against you and am only here for some assistance. I apologize if I am not the smartest Vdub user and haven't answered your questions correctly. Thanks Phaeron...I think I am just gonna give up on this issue for the time being. |

You said... But now, all of a sudden, any VBR file that I try to alter will not save...I get this error: "Error initializing audio stream decompression. No installed audio codec could be found to decompress the compressed source audio. Check to make sure you have the required codec." That says to me that Virtualdub is not opening/decompressing the audo.
A screenshot of GSpot showing the bottom so we can see the decompressors that Windows is using to render the files in GSpot. That would've let everyone see what Phaeron suspects which you are obviously ignoring. You can't come in here asking for help and then either ignore what users say to try and help you or fight them at every turn.
Instead of fixing the file correctly as suggested. There are plenty of guides on the internet on how to do this. You don't have to take my word for it.
No, you probably won't get any help over there either even though there are a lot more Virtualdub users over there than there are over here. You obviously have everything under control. Not sure why you even asked anyone for help at all. Four people have tried to help you here but you've ignored every single piece of advice they've given you. I don't need it, I already got it. I don't need to try another way, this way has always worked for me in the past. You won't get any help with that attitude. BTW, I don't know anywhere to find screwed up VBR AVI files except for file sharing networks. Phaeron told you what the problem probably was but you choose to ignore him too. I'm through arguing with you. |

| @airdave: Although you tried to obscure it, it's pretty clear to me from your screen shots that what you have there is a "dvd rip" of some movie, so consider yourself lucky that anyone bothered to try to help you at all. Especially phaeron. As far as I'm concerned, just take your dvd rips and go away. |

| Alright, waaay over the line here across the board. I don't like what I'm seeing here from all sides. Topic locked. airdave, if you're still interested in a solution, please repost your question under a new topic. Blank out the filename, I don't care. Anything out of line in that post from anyone and I'm just going to edit and/or delete like a madman, no questions asked. |
