[osg-users] fail to compile osg 3.4.0 with latest ffmpeg

[Robert Osfield]

HI ?, Could you sign with a name that we can use when reply?

ffmpeg has constantly moving API so issues like this are impossible to
prevent, get everything work then a few months later ffmpeg breaks things...

You'll either need to come up with solution for these API changes and post
these fixes to osg-submissions for us to merge or revert back to an older
version of ffmpeg.

Robert.
