"garbage" in avi files causes problem.

[Yakuza965]

I have a couple of avi files which I encoded myself using AGK. They play fine from start to finish, but when I convert them to DVD using D2SRoba the sound always cuts out at the same place at the end.

I believe this may be caused by what GSpot reports as "garbage" at the end of the file. The latest beta of GSpot says "Garbage at end" in the container info box. None of my other avi's say this apart from the two I've had sound trouble with converting.

Here are the D2SRoba log and DVD2SVCD log files.

I have tried fixing the file with DivFix but all it ever comes up with is I/O error 131 - can't seem to make it do anything else! I've also tried the VDub suggestion from the stickies for problems specific to avi. No success with that either.

I've checked the audio that was extracted from the file by DVD2SVCD and it's seven minutes too short - which is clearly why it cuts out.

Anybody any ideas where this problem is arising from, and how I can fix it?

(Sorry for the disgustingly long first post!)

Reencode from your source - that should give you better quality than going from Source -> Avi -> DVD.
You can also just reuse the AC3 instead of reencoding it. Last but not least you cant resample your audio to 44100Hz - this is not allowed for DVD Video - it has to be 48000Hz.

@Communist - he is not re-encoding or resampling the audio. This only appears in the avisynth script as it seems to stop CCE crashing on older AMD machines.

The audio is prepared in a separate stage and according to that logfile, the AC3 audio is being retained.

However, you are of course correct in saying that re-encoding from the original DVD is a much better solution.

@Yazuka - if there is a good reason why you can't re-read the AC3 from the DVD (scratched disk etc) then try demuxing it in VDubMod. Save the demuxed AC3 file over the Encoded_Audio_1 file created by DVD2SVCD. Then crash recover DVD2SVCD from the muxing stage.

Interestingly, that solution works Nick - why is it that DVD2SVCD fails to extract all the audio properly?
