    For test, we should not delete the jpg images from temp folder if debug option is enabled, than we can check if the original jpeg (came from ffmpeg) is wrong or not?

    Hi,
    1x1 most of the time is okay but like i said, on XBMC, i get the same thing.
    Like i'm debugging the thing this night, i have see thumb in temp folder and it's ffmpeg that create wrong thumb.

    For me :
    On .ts files that give me a better result is : select=eq(pict_type\\,P)
    On .avi and surely other files it's : select=eq(pict_type\\,I) but here it's horrible slow for .ts and not working good.

    Ok. We can use separeted method for ts. ;)

    Edit: TS or video codec (MPEG VIDEO VERSION 2 or AVC)?

    Hi,

    can anyone test in 1.4.0?

    Prepare two directory in my video where there are some video whithout thumbnails (or delete the thumbnail cache in config)

    1. Go to my video enter a directory where there are some video whithout thumbnails. Wait for generate the thumbnails.
    2. Go to settings -> GUI -> GUI thumbnails
    3. Change the thumbnail preview settings (row or colum)
    4. Return to my video and enter an another directory where there are some video whithout thumbnails. Wait for generate thumbnails.

    The thumbnail generator used the changed settings or not?

    Thx!

    This needs a review I think. :) I am not sure what are default values for example.

    EDIT:
    I don't know if we need
    2. If you use more than one thumb (e.g. 2x2 tiles) the time between the thumbs will be calculated automatically from the video duration. This means no more almost the same thumbs.
    at all. It has nothing to do with config. But that is for Docs team. :)

    PS: @michael_t I think you can close: https://issues.team-mediaportal.com/browse/MP1-4079 :)
    @michael_t I see that MP1-4079 was closed but it says Fix Version/s: not planned yet. Holzi added the documentation to What's New 1.5 which I moved since i thought it wasn't part of MP 1.5 however now I noticed that 4079 says Resolution: Duplicate so maybe there's another JIRA issue for this?
