Help with enabling mediainfo for DVD & Blu-ray folder rips
Presently one of the bigger limitations of the mediainfoprovider plugin is that it cannot read the information from DVD and Blu-ray folder rips (or ISOs).
There is a feature request for this here Enable media info support for folder structure rips
It would be a great improvement to mediainfo capability and many users (ebr included) keep many or most of their movies as folder rips.
Using DVDs as an example (we could try to determine the main movie within Blu-ray folder rips in a similar way) :
The reason that this is difficult to implement is that there are multiple VOB files within the main folder and we need to determine which one(s) contain the video for the movie itself (not the extra or bonus features)
Various options have been suggested in the FR mentioned above and if we could find one that was reliable it would not be that difficult to implement.

easiest way to scan for media info in a DVD structure, is to go into the VIDEO_TS directory, and poll the first .VOB file that has a size of 1,048,xxx KB – which in 99.9% of the cases will be the actual main features 1st file…
If this is correct then it would be a reliable method for locating the main video file.
As we have a large group of users here and many are making folder rips of blurays and dvds we could check to see if this is correct in practice.If it can be shown to be true with a high degree of accuracy we could use this to determine the correct VOB file to extract the info from.
If this is not reliable enough perhaps someone will be able to suggest an alternative method for determining the VOB(s) containing the main movie.
Here it is mentioned that the open source YAMJ (Yet Another Movie Jukebox) can do this for DVD folder rips and ISOs although it is in java.
Good day Chip,
I thought the DVD “IFO” file have the info, so it will be easier to read it if I am not mistaken here.
My best
Yes, that would be great. I have most of my movies as folder rips, too.
Direct from our local Wikipedia:
“….On the DVD, all the content for one title set (VTS) is contiguous, but broken up into 1 GiB VOB files in the computer compatible file systems for the convenience of the various operating systems. Each VOB file must be less than or equal to one GiB . Other DVD files include IFO and BUP files. IFO (Info) files contain all the information a DVD player needs to know about a DVD so that the user can navigate and play all DVD content properly (e.g., where a chapter starts, where a certain audio or subtitle stream is located, information about menu functions and navigation, etc.). BUP (Backup) files are an exact copy and backup of IFO files in case of corruption. VOB files without IFO or BUP files do not allow DVD menu navigation. Images, video and audio used in DVD menus are stored in VOB files.”
There is also a great write up over at VideoHelp.com. See details HERE.
Some more relevant information may be found HERE. This seems more in depth.
On a side note, how do programs such as DVDFab, and the like, collect this information? Is that something that can be utilized to acquire the information?
