Inspection shows that lzma support is optional for ffmpeg depending on 
whether or not liblzma can be autodetected.

In r126103, I've modified the ffmpeg port to explicitly enable lzma 
support and have added a dependency on port xz which provides liblzma in 
Macports and it builds +universal.
port liblzma is obsolete, replaced by xz.  port lzma does not provide 
the library only the utility.

Please update your ports and upgrade ffmpeg.   I believe this should 
solve your problem.  If not, please file a ticket against ffmpeg.
