What's the output of:
nm -D /usr/lib/libavcodec.so | grep video2

hmm, its actually in /usr/local/lib.  and this highlighted a problem with my 
ffmpeg install, in that no .so files are created unless i add  --enable-shared  
to the configuration options.

This was odd because i never had it in previous compiles.  Pulled all of ffmpeg 
out, added the new option, and nm -D /usr/lib/libavcodec.so | grep video2  
returns 

003679a0 T avcodec_decode_video2

compiled ffmpegthumbnailer and it seemed to install with no issue.  but i 
needed an ldconfig to update libraries.
