[Bf-committers] scons issues with new ffmpeg package

[Mathias Wein]

Working fine here...
also Ubuntu 7.04 (x86_64), however with gcc 4.2.1...

The " -O0 -g" makes me wonder though, are you doing debug builds?
The compiler flags look pretty messed up...probably shouldn't use
blender compiler flags to build ffmpeg.
