No Audio when using AC3 for divx encode

[Dropbear]

Hi All.

I tried my first conversion using GKnot last night, and the video came out fine, but there was no audio. I have followed a couple of guides so I think I'm doing the right thing. Something which has me puzzled is that when I finishe running DVD2AVI, there were three AC3 files there. In GKNOT I chose to use the biggest one (the first one) - I trust this is the right one to use?

Anyway I include my GKNOT log file in the hope it may be of use to someone in helping me figure out where I went wrong.

I can help, a little. Dolby Digital audio (.ac3 files) require either a sound card capable of decoding, or, you need to have an .ac3 audio codec installed. I can't help you with setting up a DD capable soundcard, since I don't have one. With DD audio, I just use an .ac3 codec. The term used around here for this is an "ac3 filter" -- as it is a decoding tool.

To get an .ac3 codec, either upgrade to Gknot 0.27, one is included in either the rippack or the system pack, or else install the most recent "ac3 filter" from Doom9's download page.

[NOTE: You did not account for the .ac3 file size in Gknot's calculator. You do that by selecting the .ac3 file in the Audio A box on the Bitrate tab.]

Thanks for the reply. I have PowerDVD on my machine and thats capable of playing DVD's with AC3 sound tracks, so wouldn't that play the sound on a divx encoded with AC3 audio???

[jggimi]

I can't answer that question difinitively.

There may be a real difference between .avi playback (usually DirectShow audio and video, hence installed codecs) then extracting an .ac3 stream from a .vob set.

My recommendation remains unchanged. Install an .ac3 filter set, see if it works. Click on this (http://www.doom9.org/Soft21/Filters/ac3filter_0_63b.exe) to download said filter.

If, instead, you have a DD-compliant soundcard, a search may reveal information I lack.

Thank you very much for your prompt and accurate help. You nailed the problem precisely...
