[Ffmpeg-devel] libavcodec undefined symbols in FFusion?

[Lee Morgan]

Hi all, I'm new to libavcodec; and fairly new to codecs in general.  
I'm trying to update the FFusion code to the newest version of  
libavcodec (and add support for H.264 in the process).
However when I try to build FFusion with the newest libavcodec I get  
about a dozen undefined symbols such as...
_av_crc07
_av_crc_init
_ff_gcd
_av_crc
_ff_log2_tab
_uncompress
_inflate
_deflate
_crc32

Any suggestions?

Thanks for your time,
Lee
