DGIndex does not determine audio delay

[vie2233hil]

Sup,

This appears to be a common issue on different DVDs

1. Straigth ac3 demux shows DELAY 0ms in filename, however after incode and muxing audio is not in sync
2. Doing "Analyse sync" produces

Delay Analysis Output (Audio ID 80)

Decode picture: temporal reference 2[I]
delay = 0
Decode picture: temporal reference 2[I]
delay = -148
Decode picture: temporal reference 2[I]
delay = -137
Decode picture: temporal reference 2[I]
delay = -221
Decode picture: temporal reference 2[I]
delay = -210
Decode picture: temporal reference 2[I]
delay = -134
Decode picture: temporal reference 2[I]
delay = -219
Decode picture: temporal reference 2[I]
delay = -207
Decode picture: temporal reference 2[I]
delay = -196
Decode picture: temporal reference 2[I]
delay = -216


Where 150ms appears to be correct delay.

is kinda "Start your project in by a few GOPs in DGIndex"

Is this because DVD was ripped incorrectly?

Is this because DVD was ripped incorrectly? No, it's because there is some crud at the start (usually some black frames).

That's a pretty provocative thread title you chose there, don't you think. Trying to get on my good side? :)

If you post an unprocessed stream sample that includes the start, I will have a look at it for you. It would be nice if it was long enough to also include a good AV sync event, like a door slam, or someone talking.
