Not quite familiar.  The code uses img_convert rather than
_img_convert so I'm curious where this one has been introduced.
Perhaps your ffmpeg plugin maps img_convert to _img_convert in some
way, but doesn't implement the later.

Can you check to see if your ffmpeg headers contain img_convert?

Robert.
