Problems with slideshows

[Lincoln Burrows]

I noticed that while AnyDVD, MakeMKV, TsMuxer and etc. can work with the movie and all featurettes from Blu-rays, there's a problem with the photo galleries/slideshows.

I mean, if you visit the Blu-ray disc and go to that content, you will see a 2m40s slideshow (for example) with 50 pictures. However, when I decrypt the disc and search for the same contents in the BDMV/STREAM folder (using MPC-HC instead of Total Media Theatre), I see a 10 MB m2ts file that, while it says it has 2m40s, can only play 1 second and showing all pictures in that interval.

As if the lenght of that slideshow was only determined by the original authoring (decrypted or not) itself.

It turns out if I insert the original disc (or the decrypted files, but only using TMT and not MPC), I will be able to see all photos in this slideshow and just watch while the pictures are being switched by the player itself.

If I use MakeMKV or TSMuxer I will only get this broken file.

I tried to do the same thing in another gallery and the lenght of that file was 1 second (in Matroska format). The full lenght (during 1 second, and also broken) can be noted if you attempt to open the original m2ts file.

What should I do?

Is there a way to fix this?

As you can see, it doesn't matter if I try to open the original m2ts (only the specified file) or the converted (in MKV). They will both last 1 second.

In case you need an example, this is a 7 MB file. Try to open in MPC-HC and see what happens.

And try to open this one (m2ts) - 8 MB:

I think this is also happening on DVDs.

For Blu-rays, I believe you'll discover that the delay between "slides" is determined by information contained in the applicable ".MPLS" file in the "PLAYLIST" folder/directory.

(Similarly, for DVDs, info is in the applicable ".IFO")...

Ok, but how do I fix that?

I tried to open the BD folder using this program mentioned here:
http://forum.doom9.org/showthread.php?t=139008
http://pel.hu/bdedit/

And it's listing the PLAYLIST folder with all applicable MPLS files with the proper lenght. However, I noticed something interesting.

See the image:

If I push the "Play" button on this screen, the respective file (with the slideshow) will finally play with 2 minutes and not 1 second. But as you can see, BDEdit instructed BSPlayer (or any other player for that matter) what is the correct lenght from these specific files identified as "slideshows".

My question is: how do I generate MKV files (not compressed) from those slideshows? Are there any guides about this? Why aren't MakeMKV or TSMuxer already doing that? I thought they were reading the BD folders which are telling the exact lenght of those files. Unless this is a bug and there's no way to fix it unless it's done by the authors?

P.S. I tried to open the applicable MPLS files using TSMuxer, and the correspondent file (m2ts) was loaded by the program. But when I used the Demux option, it simply replied "can't open the file". And I don't see the difference in instructing TSMuxer to open MPLS files.

If you use MakeMKV to do a FULL DISC backup, you'll see that it handles the "slideshow" properly. On the other hand, if you use MakeMKV to make individual .MKV files from the Blu-ray's individual TITLES, it has no source of information (no .MPLS) to determine how to display and delay the "slide show" images...

I don't understand the difference. All files were decrypted in my Hard Drive. I am using MakeMKV and selecting the index.bdmv from the BDMV folder. I am selecting which tracks and titles I want to be converted into Matroska.

So what do you mean by Full backup? Don't tell me I have to put the encrypted Blu-ray on my PC drive and use MakeMKV to decrypt?

And besides index.bdmv the only file MakeMKV will look for while browsing a BD folder is BDMV/MovieObject.bdmv.

Well, since no one came with that idea, I have been thinking today how we may let the original files still available from the BD authoring, minus all the others we are able to convert into Matroska without experiencing problems.

I mean, the whole idea is to use the software Total Media Theatre from Arcsoft to playback the disc/BDMV folder, displaying all menus and sorts of things, but only actually accessing the slideshows. All other contents removed, including the movie and extra features that I was capable of converting into MKV.

For example:

The Predator (1987) - Ultimate Hunter Edition

* In this case I had to left 0,97 GB. The largest files were 00111.m2ts and 00112.m2ts with 200 MB each. They are nothing but trailers from different movies distributed by Fox (and made in 2010).

I have also left the m2ts files corresponding to the main menu and piracy warnings. If I had left those trailers or other m2ts files out of this directory, TMT would send me a black screen and would never access the main menu where I can find the option to see the slideshows.

This is the list of files that should be kept from this title:

(Use a software like MD5Summer to check this file, or Notepad).

About the slideshow contents, they are two:

- Photo Gallery
- Predator Profile: A text-and-photo-only profile of the alien predator, detailing all of his weapons and armor. *

* You might think this "Predator profile" is similar to the contents from "The Sound of Music" (see this thread for more details):

http://forum.doom9.org/showthread.php?t=158216

But they are not hidden or unavailable for anyone that wants to convert them.

I am saying that because the "Many a thing to know" curiosity track from "The Sound of Music" (1965) changed the language for this featurette according to the language selected for the disc on the TMT settings.

Changing the language here will also change the "Predator profile", but each language corresponds to a different m2ts file, it's not being changed/inserted in a hidden way.

I will also check what files we should keep from those titles:

- The Adventures of Robin Hood (1938)
- The Truman Show (1998)

And in the future, edit this post with my findings.

Red Dragon (2002) - Blu-ray - Central Eastern Europe release (the others are similar)

Extra feature:
Lecter's FBI File and Life History, a text extra showing Lecter's "file"

Not a slideshow per se, but needs BD structure to browse between each page from this "file". When converted to MKV, all pages are displayed in 1 second.

The following files were left in the BDMV/STREAMS directory:
