Summary

0001312: File loading: Crash when loading images with 10.06 aspect ratio.

Description

When loading a file with aspect ratio of about 10.06 (width divided by hight) Kdenlive crashes. At least this seems to be the case so far as I have been able to pin down.

Steps To Reproduce

Load an image with aspect ratio of about 10.06.

Additional Information

Added are backtrace, jpg, png and gif file that crash Kdenlive.

You can reproduce in melt by creating a profile with width=48 and height=36 for example (it seems to be triggered by small image sizes). For a test, edit width / height of the cif_pal profile to 48X36, then just call: melt -profile cif_pal 1006x100.png It crashes. I uploaded the 1006x100.png image for easier testing

(0004535) ddennedy (developer) 2010-01-19 18:30	The smallest image the scaler can produce is 6x6. My hunch is that it hits this limit and then the rescale (pad) filter assumes scaling succeeded (or rescale sets some properties incorrectly). So, I expect to be able to fix the crash but perhaps not give you an interesting result. I will look into this further soon.
