Hello,
I am testing the transcoding of different DPX files from different sources.
I have here 2 files which cannot be opened by ffmpeg.
https://dl.dropboxusercontent.com/u/26129407/ProblematicDPX_1.zip
When I open the files with ImageMagick and GraphicsMagick they look
distorted (can be seen in the png from the zip file).
Opening the files with Photoshop they look also very weird but different
to GM and IM. (see PNGs in zip)
Any ideas whats going on here?
Best Regards
Christoph
