Cool!!!

Well, just testing the 1204b1...

1. The logging is now correct (1204b1 and 1202 coherent).
2. The demuxed m2v is correct.
3. The demuxed sup file (just one subpicture) is correct.
4. The demuxed audio file is not correct: the first byte of the second audio packet in the vob file is missed in the stream demuxed with release 1204b1. See the attached picture for reference:

ASAP I will send to you, via PM, some further detail on the subject...

Cheers,
SD

Weird! Seems there is some bug inside... Sorry, I should have done more tests before output the beta..

jsoto · 15th April 2005, 23:21

Found an uninitialized variable in audio extacting code.., so the results are unpredictible in 1.2.04b1

EDIT:
@all
1203 has some bugs extracting the audio and 1204b1 still has one. Please use 1202 in the meantime.

Hi jsoto,

Works like a charm now!
And man, was i glad to see the "include end time"-option

Thanks for this very handy tool

jsoto · 21st April 2005, 23:58

Good!.
I'm a little bit busy at work now and cannot test it too much....

When demuxing (by cell) with PGCDemux I seem to be getting a different delay on the audio than DVDDecrypter (or Smartripper). Also a binary compare shows the audio files to be exactly the same but the video files have 2/3 bytes different (around the 5C offset I believe). Is this normal and does this have anything to do with the delay? Which delay is correct?

mpucoder · 14th June 2005, 13:19

PGCDemux calculates the delay properly for remultiplexing the audio and video directly, or with the newer avisynth programs. DVDDecrypter and SmartRipper calculate the delay for the old dvd2avi which dropped video frames.
The vidoe bytes that are different are probably the gop timecode. Since there are no fixed offsets in mpg that's only a guess. Look for the header preceeding the bytes that are different, it will be 00 00 01 xx - the xx will tell you what header you are looking at. B8 is the gop header, which contains a timecode. Some rippers give you the option to reset the timecode to start at 00:00:00.00

candela · 14th June 2005, 20:04

Thanks. It's indeed the timecode. If i don't let dvddecrypter reset the timecode the files are identical.

jsoto · 14th June 2005, 23:22

@mpucoder
Thanks for the clarifications.

@jsoto
1. With PgcDemux I can demux only 1 PGC or 1 VID or 1 cell. Sometimes I need to demux some part of PGC (for example, 1-12 cells of 14). Can you make it like in ReJig?
2. Also, it would be usefull to allow choose what audio/subtitle track to demux.
3. When I demuxed PGC and then muxed it with another .m2v by IfoEdit, in reauthored DVD subtitles wheren't visible. DVD player found subtitles, I can make them visible or not, but actually they haven't made visible. When I demuxed & muxed DVD with ReJig - all is right. Binary compare showed that .sup is different.
4. Do you plan any kind of "PgcMux"?

Also, when I mux DVD with IfoEdit, if AC3 have more duration than video - in the resulting DVD after video ends it still plays the sound. Can anybody advice program that can cut sound/subtitles according to the video stream?

If you're after a good program to mux it all back together, then I can highly recommend MuxMan by MPUCoder as a very good alternative to IfoEdit and ReJig...

No, I've no plans to do this. You can cut your PGC before....

I do not think so. In terms of saving disk space, Subs and audios are not so big, and in terms of speed the effect of demux only part of the streams is minimum.

Mmmm, there are many possible reasons to do not show the subs (i.e, if you change the AR of the m2v and do not change the stream number in IFO, the colors, etc). I've never found a problem here...couild you describe in detail what are you doing, please?.

4. Do you plan any kind of "PgcMux"?

God!, no. (mainly because I do not have the knowledge to do it). Use Muxman instead.

Sajan · 23rd June 2005, 19:35

Mmmm... I understand... So, without being able to choose set of cells to demux I would like to demux PGC with ReJig and use PgcDemux to generate CellTimes.txt only. And my strange problem with subtitles will dissapear itself

Thanks for reply.

@jsoto

Request for a future project when you're taking a break from VobBlanker.

In VB, we can cut VOBs. I was thinking about how that could also be implemented into PgcDemux. Say, I wanted to demux a PGC but wanted to cut out the last cell first, since it's a blank. Just wanted to automate things quicker.

jsoto · 19th September 2005, 01:44

Noted, but I have some ideas in mind...

Yeah we promise not to look

Well not with both eyes at once anyway

jsoto · 19th September 2005, 18:25

No, no, don't get me wrong, nothing really impressive....only a few additional features in VobBlanker, like split cell.
