[Sumover-dev] Vic H264 compilation issues

[Douglas Kosovic]

FFmpeg 0.5 was released two days ago, the first time in a very long time 
  that they actually made a release, perhaps we might want to consider 
targeting that instead of a SVN version.

To get x264 to do the right thing as a user with no write privileges to 
/usr/local, I was doing the following to build VIC RPMs:

./configure --enable-ipv6 --enable-gpl
(cd x264; ./configure --prefix=`dirname $PWD`/x264; make; make install)
(cd ffmpeg; make)
make

I still need to do that with x264 and the latest checkin in the mpeg4 
VIC branch, although I haven't tried with newer versions of ffmpeg and x264.
