Can you please describe a task and its workflow that uses demuxed chapter information? I need to understand the context.
Demux a BD, compress with x264, compress audio to ac3 or aac, remux with chapters, watch on a laptop while traveling by train or plane :D

Are you looking for simple or XML format for the demuxed chapter files?
Whatever format you are more confortable to extract. MKVToolnix can digest any.

Since you're the guy that asked for this, I'll appreciate your feedback on whether it is doing what you need.
Gonca too. We are partners in crime :D

Will test asap.

Thanks, tormento. I suppose I should call you two guys the usual suspects now, huh?

The main thing is that it does not honor the project range for chapters. But it's not clear that such a thing would be needed, and in any case, I could post-fix-up the demuxed file based on the StartTime of the project range (I hope it's not needed!) The scenario you gave would not require it.

Here's another thought. I would like to emulate gMKVExtractGUI's checkbox design but Win32 does not have a listbox with checkable items. I'll see if I can subclass it and make one that does. That is the reason for the somewhat clunky selection method I have now.

SRT delay

Post by tormento » Tue Mar 06, 2018 4:24 pm

@admin :hat:

I was playing a bit with Justice League and Detroit BDs.

I noticed that the srt filenaming gives strange delay results, such as: DELAY_150751ms or DELAY_166668ms.

I have compared with the srt extracted by GMKV and they are identical in time codes and contents.

The delay is the start time code of the first subtitle

Usual?
Not odd, rare, strange, etc?
Just usual/average :facepalm: ;)

Ah, so that is the significance of it. Do we really need the delay value in the filename then? Seems not to me.

Realistically, no
Because it is a subtitle the delay in the name it is ignored by mkvmerge

I can't understand why.

Delay should be the one you put in MKVToolnix when you don't want to edit srt with same fps but from different source (and it happens, when you need to translate from foreign language and the foreign BD edition has more intro or less than yours).

AFAIK it's not true. MKVToolnix honors delay for every stream.
