Sadly, the Debian maintained variants aren't distributable.  According 
to the readme in the source code:

"Currently the following video encoders are disabled in the ffmpeg
package: H263, H264, MPEG2 video, MPEG4 and MS-MPEG4. No *decoders* are
disabled in any the ffmpeg package!"

So there are plenty of patent encumbered formats still included.

As for building VLC without FFMPEG (--disable-avcodec, etc), I'd like to 
provide a solution that would work as a groundwork for modifying all 
FFMPEG powered software.  Besides, one could still run afoul of patents 
if they distribute source code that *could* be compiled to support 
patented codecs, even if the binarys you distribute alongside it is 
compiled without such support.  As such, it is safest to completely 
remove the offending code from the source.
