Thumbnail generation - design problem: thumbnails are almost same and not very informative. (3 Viewers)

Hi,

I tested it with a sort manual recording (1x1 title). It works! Great work!

Quality is also looking good, but i still see a lot of pixelation on some thumbs.

Pushed in master

I haven't checked but I assume this require documentation? Are Docs already done for this?

 

[Sebastiii]

If you help us (vuego and me for it)
The doc should mention new options :

Thanks

 

[Holzi]

I will create a new page so that you can review it.

Wiki page created: http://wiki.team-mediaportal.com/1_...nfig_Tool_Changes/Thumbnail_generation_rework

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

Hi,

there is an second feature in this rework. If an user press F9 (enter the context menu) on a movie (in my video screen), the user can refresh the thumbnail. MP will generate a random value and increase the time offset to generate a new thumbnail.

Maybe you can make a screenshot and add this to Wiki? Thanks!
