Hello,
I'm trying to do a new installation of OSG on a Fedora-12 system, and
I'm having trouble with compiling -- it complains about "the use of
enum 'SampleFormat'" in a handful of places -- see below for the full
error output.
So, I suspect that this may be a version issue with FFmpeg, but I cannot
find any documentation of what version of FFmpeg I should be using.
Further, since it appears that the FFmpeg feature is a plugin, I would
suspect
that it is optional, but the cmake settings reveal no ON/OFF flag for
ffmpeg.
I have tested this with both OSG versions 3.0.1 and 3.1.1, and get the
same result for both.
Can anyone inform me of either 1) how to just disable ffmpeg, or 2) what
version of ffmpeg I should try to install?
Here is what my currently installed ffmpeg reports:

Use -h to get full help or, even better, run 'man ffmpeg'
And here is the end result of the attempted compile:
