Hi,

And nothing is output, no demux happens.

I use bash script to run it automatically (on GUI seems to work fine)

Code: Select all

#!/bin/bash

OIFS="$IFS"
IFS=$'\n'

for fld in "$@"
do
	playlists=$(/home/script/dgdemux/dgdemux -d "$fld")
	mpls=$([[ $playlists =~ ([0-9]+).mpls ]] && echo "${BASH_REMATCH[1]}")
			
	mplsPaths=($(find "$fld" -iname $mpls.mpls))
	mplsPath=${mplsPaths[0]}
		
	name=$(basename "$fld")
	output=/home/demux/$name
	
	if [[ ! -d $output ]]; then
		mkdir -p $output
	fi
	
	/home/script/dgdemux/dgdemux -i $mplsPath
	/home/script/dgdemux/dgdemux -i "$mplsPath" -o "$output/$mpls"
done

Please give me a link to purchase the disk. I don't do torrent stuff.

Posted: **Tue Oct 12, 2021 7:57 am**

I updated post with bash script.

The disc can be found there:
https://www.amazon.com/Halloween-4-The- ... B07GNTCCDM

Posted: **Tue Oct 12, 2021 8:50 am**

You talk about bash. You're on linux right? Then why do you say "on GUI seems to work fine"? There is no linux GUI.

Have you tried it on Windows?

If on windows, you have GUI and CLI, also CLI via some script. Please test GUI and CLI directly first. Then we can look at scripts.

But first are you on linux or windows?

Posted: **Tue Oct 12, 2021 9:18 am**

I try on Linux

But it worked for other BDs, but not for this.

on my Windows machine, seems to work fine through GUI.

Posted: **Tue Oct 12, 2021 9:24 am**

On linux did you try without the script, just running dgdemux from a terminal?

Posted: **Wed Oct 13, 2021 8:36 am**

Sorry for late reply

Yesterday I was sick, strange that works with command directly

I checked script that would execute same command and therefore no output.

Very strange

Posted: **Wed Oct 13, 2021 8:47 am**

OK, thank you. I'll take a closer look at your script.

Posted: **Wed Oct 13, 2021 9:26 am**

You can use that script on your side and check if occur that multiple MPA

Posted: **Wed Oct 13, 2021 10:34 am**

Sure, but only if I blow $36. Wanna pay that for me?

Posted: **Wed Oct 13, 2021 1:45 pm**

Haven't analyzed your script in detail, but first, in this fragment:

/home/script/dgdemux/dgdemux -i $mplsPath
/home/script/dgdemux/dgdemux -i "$mplsPath" -o "$output/$mpls"

Why do you have quotes around $mplsPath in the second line but not the first? If the path has white space that's going to be a problem. I note that your disk title has white space.

Second, are you just choosing the first MPLS file? If not, how are you choosing it?

Third, IFS is defined but not used. Did you give the full script or just a fragment?

Could you visit more regularly when we are actively working with you on your problem? It chafes to have to send emails asking for a response. Even though you acknowledged that DGDemux operates correctly when invoked manually we're willing to help you debug your script.

Posted: **Thu Oct 14, 2021 4:10 am**

Second, are you just choosing the first MPLS file? If not, how are you choosing it?

I will explain briefly what script does

Code: Select all

playlists=$(/home/script/dgdemux/dgdemux -d "$fld")
mpls=$([[ $playlists =~ ([0-9]+).mpls ]] && echo "${BASH_REMATCH[1]}")
			
mplsPaths=($(find "$fld" -iname $mpls.mpls))
mplsPath=${mplsPaths[0]}

mplsPath will be first found mpls file found by first item (mplsPath=${mplsPaths[0]}) (when run -d PATH_TO_BD_FOLDER)

If run dgdemux -d PATH_TO_BD_FOLDER will out a list of mpls... I will take first one.

Here:

Code: Select all

mplsPaths=($(find "$fld" -iname $mpls.mpls))

I'm taking full path to that mpls file in order to send it as argument to -i flag

/home/script/dgdemux/dgdemux -i $mplsPath

I will add it and will try again

But the real issue is not regarding to quotes to variable (if so, that wouldn't output the many MPA lines).

Is strange situation that output a lot of MPA lines there, since the mpls is detected and trying identify the streams.

Third, IFS is defined but not used. Did you give the full script or just a fragment?

It is full script, you'll see bash directive in first line.

Could you visit more regularly when we are actively working with you on your problem? It chafes to have to send emails asking for a response. Even though you acknowledged that DGDemux operates correctly when invoked manually we're willing to help you debug your script.

I will try as much as possible since I use extensively your program, I still love it !

Later edit:
I am extremely idiot ! the mpls found is located in BDMV/BACKUP/PLAYLIST/ folder instead in BDMV/PLAYLIST...

Fixing it will solve issue

Posted: **Thu Oct 14, 2021 10:15 am**

The first MPLS is not always the correct one.

BDMV/PLAYLIST is the correct primary location. Don't know about your torrent version though. Perhaps the BDMV/PLAYLIST folder is corrupted.

Marking resolved.

Hi.

The problem with that disc, is that it has an 18 second m2ts file which has very different audios than the main m2ts.

bdinfo can somehow show the correct info, but eac3to, dgindexnv, tsmuxer and what else, will show "wrong" information.

You will have to use dgdemux and select "skip first m2ts" and then everything will be fine.

The problem with that disc, is that it has an 18 second m2ts file which has very different audios than the main m2ts.

bdinfo can somehow show the correct info, but eac3to, dgindexnv, tsmuxer and what else, will show "wrong" information.

You will have to use dgdemux and select "skip first m2ts" and then everything will be fine.

A bit more explanation.

00005.m2ts is 18 seconds, and has very different audios than 00000.m2ts.

If you demux including the 00005.m2ts file, things will get messed up, as the audios in the 2 m2ts files are very different. If you demux with "skip first m2ts" then all will be fine. At least it worked on my retail disc.

The 18 seconds is just some logo that isn't needed. Btw, Halloween 5 has the same thing, which means to get a dgi file, one will have to first demux with dgdemux with "skip first m2ts" and then use dgindexnv to demux the video. Can't find the option to skip first m2ts file in dgindexnv, so I think it needs to be a two step proccess to get a dgi file.

Thank you for the analysis, renols. Could be time to add those extra DGDemux options to DGIndexNV. I wonder, though, can you open the disk and then go into the Open menu and delete the first M2TS from the list?

Hi.

Yes, that actually seems to work.

When I open disk and enter the demux menu, I just see a lot of 2 channel DTS HDMA tracks.

If I then go to the open menu, and delete the first m2ts file (00005.m2ts) it looks like dgindexnv "opens" the disk again, and the demux menu now looks correct, with TrueHD audio and several 2 channel AC3 files.

Thanks for pointing that out. Saves me the step of having to save a 40 GB big video file, which I then must proccess to get the dgi file.

The only downside, seems to be that the language information in the filenames seems to disappear. I guess it does the same as not choosing "Open disc" but just choosing Open file, and selecting the 00000.m2ts file.

If I use dgdemux with "skip first m2ts" the language information in the files is kept.

Ah yes, thank you for pointing that out. I'll see whether the language info can be kept in such a case. If it becomes too complex, I'll just implement the skip first option for the Choose MPLS File dialog.

The first MPLS is not always the correct one.

BDMV/PLAYLIST is the correct primary location. Don't know about your torrent version though. Perhaps the BDMV/PLAYLIST folder is corrupted.

Marking resolved.

Is not corrupt, I made mistake sending PLAYLIST file from BACKUP folder instead the BDMV one.

I saw that first MPLS is not always correct and is very hard to find right one except bdinfo.

It is quite easy to find with DGDemux too.

Can tell me how?

You should ask Curly. He's real good at stuff like that. You don't have to thank me.

Posted: **Tue Oct 19, 2021 1:03 am**

And (s)he can see this topic ?

@Sonic3R

Curly is a man's man, no she!

Look at the MPLS chapter count and the duration. If still in doubt do a preview.

@renols

Can you please test this version with the skip first M2TS option? I intentionally do not save the state of the skip first checkbox in the Choose MPLS File dialog. Use this with the latest DGDemux.exe.
