(all of the libav* libraries? lbavcodec, libavformat, libavfilter, etc)

The license and livense FAQ should explain that, but my understanding is 
that you only need to distribute the source code for the parts you 
distribute in binary form. However.... you need to look at specific parts 
for the license types. For instance, libavfilter has parts that are GPL in 
addition to those that are LGPL.

As long as you -do- make them available, you should be compliant. The LGPL 
2.1 license says "You must make sure that they, too, receive or can get the 
source code."

If you have not actually read the LGPL, please do so. It's pretty clear.
