Description tim474 2009-08-17 17:37:16 UTC 
Version:            (using KDE 4.3.0)
OS:                Linux
Installed from:    Ubuntu Packages

Zoom in/out option for video, like it was in Kaffeine 0.8.8 or earlier. This wish was written to the Kaffeine bug tracker, but was said: "Both DragonPlayer and Kaffeine4 use Phonon as engine, and atm Phonon does not
provide zoom in/out API."

I agree. For the bug filed against kaffeine 1.0 see #159715. Devs said that it relies on phonon offering zoom-support.
Comment 2 Harald Sitter 2011-03-02 02:18:24 UTC 
Why would this be useful?
Comment 3 Stefan Neufeind 2011-03-02 08:40:34 UTC 
I've quite a few times had files which were "badly" encoded and might have had just some noise on the edges, that could easily be "cropped" by zooming in a bit. Also it might be that you have a "wide" image and view it on a 4:3-screen (possibly), and in those cases you might want to zoom in a bit - cropping of a bit from left and right, but increasing see overall picture-size to be able to see it better.

"Zooming" imho could also be offered by a feature allowing to "crop" the image selectively (and then fitting the resulting image on the screen).

It was possible in earlier versions of Kaffeine for example and I must admit that I missed it when upgrading to the Phonon-based version.

Isn't that what the videowidget's scalemode already does? (granted the possibilities are limited to two options, but I personally do not feel very motivated adding code for the sake of working around crappy video encoders)
Comment 5 Jean-Baptiste Kempf 2013-05-25 18:50:36 UTC 
What are the other use cases than the 2 already existing options.
