Bug 186935 – media-libs/mlt need --avformat-swscale if media-video/ffmpeg-0.4.9_p20070616-r1 is installed

• Status: RESOLVED FIXED
• Product: Gentoo Linux

kdenlive (0.5svn not in tree) fails to start with this error:
Failed to load plugin: /usr/share/mlt/modules/libmltavformat.so: undefined symbol: img_convert
Same error importing video-files if using kdenlive-0.4

Checking http://forums.gentoo.org/viewtopic-t-553542.html I found out that media-video/ffmpeg-0.4.9_p20070616-r1 is automatically configured with swscale enabled, but mlt has it disabled.

proposed patch:

with this patch applied I can start kdenlive-0.5svn (or open video-files with kdenlive-0.4)
