I am running Slackware 13.37 64 bit
I installed kdenlive via the binary packages via this site... it all went fine...
except the version of ffmpeg on here doesn't seem to have been built properly as it's missing binary files in it... I did report it but not heard back...
anyway as the ffmpeg was incorrect I used alienbobs build of ffmpeg and that installed fine.
Kdenlive is running fine.. ffmpeg is running fine... but kdenlive refuses to find ffmpeg.
my pastebin of the output of 'ffmpeg': http://pastebin.com/3gPfp5n2
the ffmpeg binary is located: /usr/bin/ffmpeg
