Detection of .iso archived DVD

Help

  • I noticed that MediaInfo is able to inspect even an .iso file!

    It's a big deal because I've all my DVD archived in that extension.

    However, it would be fantastic if it could be possible to detect by the program the VTS_01_0.IFO instead of the - I say, maybe - the VIDEO_TS.IFO file.

    In facts, this is what I get from the iso file:

    General

    No audio languages, no subtitle information. But, if I mount the image and I select the VTS_01_0.IFO file I get:

    But some other information are missing, like the audio bitrate information.
    How can I get all the information?

     
    • > I noticed that MediaInfo is able to inspect even an .iso file!

      Not exactly: the MPEG-PS parser detected the stream in the ISO file, and has analyzed it.
      ISO file is not supported.

      I plan to have later:
      - ISO file support
      - DVD structure support. Currently, IFO and VOB info are not merged, so you can't have all in MediaInfo at the same time.

      No idea about when I will be able to work on it.

       
    • Ok, I understand.

      Anyway, thanks for your prompt response and, especially, for your valuable work.

      >>> I previously was able to inspect iso files with mediainfo.  I'm not sure what has change, but can no longer do this.   Using Graphedit, I am able to see that I don't have a filter to open the ISO file. 

      Can you tell me which MPEG-PS parser can evaluate ISO files?
