View Full Version : Yet another Xvid to DVD thread

Okay, so I've been running around this thread trying to find if this problem's already been solved, but I couldn't find any thread to deal with it. Forgive me if this problem's already been solved and I just didn't know.

I've been following the AVI to DVD guide, but I encountered a snag already at Step 2. GSpot and AVICodec told me I had an MP3 audio stream

(GSpot said "0x0055(MP3) ID'd as MPEG-1 Layer 3"
and
AVICodec said " Audio : 90 MB, 125 Kbps, 48000 Hz, 2 channels, 0x55 = MPEG Layer-3, Supported")

but I couldn't open the file in VDub ("Couldn't locate decompressor for format Xvid. VirtualDub requires a Video for Windows compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Player, are not suitable.").

I remember reading somewhere that this certain type of audio was a) an illegally-created audio stream to fool DivX players, and b) that VirtualDub wasn't capable of reading Xvid files. I tried using VirtualDubMod, but the same thing happened.

I also tried the guide on afterdawn.com, where I used TMPGEnc to convert the entire file to MPEG-2. But, sadly, I couldn't get it to recognize the avi file as a video file. ("File 'blahblahyaddayadda.avi' can not open, or unsupported." Strangely, I can open it as an audio file just fine.)

Finally, I went and just converted the avi directly to mpeg-2 using Win AVI converter (and, on a separate occasion, Xilisoft avi converter), but the first was only a trial version and pasted an annoying message on top of the file and didn't play the audio at all, and the second only did five minutes of the avi and also didn't play any audio.

So basically I'm back at square one. Right now I'm just hoping to get the audio problem fixed.

Which brings me to my question - Is there a way to decompress my audio stream without VDub? And how do I go about it?

Thanks, and sorry for any inconvenience.

Hi!

"Couldn't locate decompressor for format Xvid."

This message has NOTHING to do with audio. It's telling you that you have to install an XviD VIDEO codec on your system...

Yeah, I already have the right codecs and all that jazz. I can play the video just fine in Windows Media and BSPlayer.

you MAY have a decoder to see xvid clips

but virtualddub needs CODEC

install latest Koepi's XviD build

BHH

Okay... heheh... that got rid of the video codec issue (thanks a bunch), but now there's a new error.

"VirtualDub has detected an improper VBR audio encoding in the source AVI file and will rewrite the audio header with standard CBR values during processing for better compatability. This may introduce up to 23721 ms of skew from the video stream. If this is unacceptable, decompress the *entire* audio stream to an uncompressed WAV file and recompress with a constant bitrate encoder. (bitrate = 125.7 +/- 16.4 kbps)

So what I'm getting from this is that the VBR was encoded the wrong way and VDub's gonna have to rewrite some of the encoding with CBR values so that it'll be more compatible. By doing that, it'll produce up to 23? 2.3? .23? seconds of asynch with the video. If I don't want to do that, I'm gonna have to decompress, change to WAV, and recompress.

1) What's the difference between VBR and CBR?

2) Will the change affect things in any way (besides the skew)?

3) I'm trying to use VDub to change the audio to wav format, so the suggestion it makes is kinda... well, pointless.

4) Does ms = microseconds = .00001 seconds?

If you had the original disc, you wouldn't be having this problem, you could simply rip to DVD. Take a look at the Announcement at the top of the Newbies forum and Doom9's Fair Use Policy (http://www.doom9.org/disclaimer.htm).
