ffmpeg with libavfilter

[Jon Keane]

Hello,

I'm trying to use the yadif filter with ffmpeg through macports.
Unfortunately it looks like the stock install of ffmpeg doesn't allow
for avfilters, despite the fact that it seems to be enabled in the
configure arguments. (And it would seem that libavfilter was enabled
by default in ffmpeg since Fri, 7 May 2010 according to git) Is this a
known problem? Is there someway to enable avfilters through macports?
Thanks
