I'm sure there's more in your Makefile. :-) Why don't you show it?

What was the command triggering these errors?

I'm not sure, but let me guess that when linking against libavcodec.a,
you are missing the dependency on libvpx (and libmp3lame). The linker
command line should include "-lvpx" and "-lmp3lame", because static
libs such as libavcodec.a don't advertise these dependencies to the
linker.

By the way, questions regarding programming with libav* are best
directed at the libav-user mailing list. This list is more directed at
the use of the command line tool or the configuration of de/muxers,
filters, an so on.
