hmm, are you using the CVS version of Gem ?
there are some better linking options in the CVS-version (basically it 
adds the output of "ffmpeg-config --plugin-libs" which adds more 
libraries than just libavcodec and libavformat)
if not, you will probably have to add these flags by hand: 
"-lavformat_pic -lavcodec_pic -lvorbis -lvorbisenc -ldts_pic -la52"

if you like to add libMPEG2-support you are welcome!
