The present ffmpeg plugin using the deprecated img_convert method, and
this is in the libavcodec.sp of svn version of ffmpeg, as are the
sws_scale and associated methods:
nm ./libavcodec/libavcodec.so | grep img_convert
000000000008bd00 T img_convert
rob...@harris:~/3rdParty/ffmpeg$ nm ./libavcodec/libavcodec.so | grep sws
000000000009ae20 T sws_freeContext
000000000009bed0 T sws_getCachedContext
000000000009bdb0 T sws_getContext
000000000009b8a0 T sws_scale
But... the installed headers don't included any of them. So it looks
like if your app is compiled against these methods say from an older
rev of ffmpeg it will work when linking against a new rev. But... you
can't compile against these functions without adding the headers in
some way.

Perhaps another way would be to move the implementation of img_convert
directly into our plugin.
