View Full Version : Why do some AVIs have garbled audio in VLC, but fine w/ WMP? Is it my decoders?

I've encountered a problem for the first time with some of the AVIs that I've encoded.

Usually I play them using VLC Player just because it can automatically read the PAR that I've set in my anamorphic encodes (WMP doesn't resize them correctly). But today I was double checking some new AVIs that finished encoding last night, and I noticed that the audio would get garbled in certain parts of playback. There are no speed problems, and the audio stays in sync, it's just garbled like as if the people speaking were suddenly underwater and choking. :scared:

Anyway, at first I thought it was my MP3's 'cause I started transcoding using a different version of LAME recently and also using VBR instead of the GKnot default of ABR, but I went back and listened to the MP3 files and they sound fine. So then I tried playing it in Windows Media Player... and it turns out the garbling doesn't happen in WMP. :confused:

I'm still a bit new to most of the players and decoders, so I'm wondering if someone can help me out.

My first theory is that it has something to do with decoders?

How can I verify which decoder WMP is using? And I'm not sure about this, but does VLC player not use any outside decoders? Is everything in VLC already?

If WMP is using a decoder that can process my AVI files better, is there a way to make VLC player use that decoder as well?

(Unfortunately, even though I've learned a lot about encoding xvid and transcoding audio etc., I'm embarrassed to admit I've never fiddled around w/ the decoders and players before, so this is one area I'm a completely clueless newbie in. I realize this is a chunk of missing essential knowledge, so please bear w/ me and TIA for any help you can provide!)

Play the file in WMP, open GraphEdit (http://www.digital-digest.com/dvd/downloads/showsoftware_graphedit_141.html) and choose File > Connect to remote graph.

That is correct.
