Hi, I'm hoping someone can help with a problem I'm having. I've spent a few days trawling the net and have tried a couple of solutions to my problem but have not found anything to my satisfaction. I have recently purchased a Dlink 320 media centre and am generally happy with it (after several weeks of playing around with firmware, media centre s/w etc) but some of my videos won't play because the box does not support AC3 sound. I have tried re-encoding these with VirtualDub but I'm not happy with the reduction in quality of the video element (presumably becuase of the lossy decoding and re-encoding). Is there anyway that I can split out an AVI file and re-encode ONLY the audio element leaving the video component untouched? Any help or suggestions would be greatfully received as I'm coming to the end of my limited knowledge now
If you have an AC3 AVI and you need MP3 audio instead (right?) that's a big job - but an audio job only :^) Yes just direct stream the video like d said. I would use Nandub, open the AVI and select save WAV. It will demux the audio file. It may say WAV, but it will be I think in its native format ie. AC3 in your case. Once you have an AC3 file, you need to use BeSweet (Azid) to decompess it to WAV. It's a little bit artistic here, because you can adjust your downmix from 5.1 channels to 2-channel. You can adjust boost, normalization, compression level, etc. There is a well-known trick of mixing the LF (subwoofer) channel into the main L & R, at the recommended -3dB. Learning Azid is probably the most challenging part of the job! Then, encode to MP3 (hopefully VBR?) in whatever way pleases you. I use LAME 3.96.1 with CDex. Then re-mux AVI using Nandub. Hope this helps, Regards
