Problems with slideshows
Posted: Fri Oct 29, 2010 11:25 am
Here's my description of the problem. Maybe this is something that needs to be corrected in future versions of MakeMKV?
BTW, the title tested was The Adventures of Robin Hood (1938) - Blu-ray.

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.
I tried to open the BD folder using this program mentioned here:

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

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.
