Using the newer ffmpeg breaks quite a few programs that build off of
ffmpeg. The location and names of the header files have changed, the
name of the options, in some revisions ffmpeg -formats does not return
proper info, so programs that are gui encoders for ffmpeg fail to
notice ffmpeg is even installed.  DVDStyler, wxSVG, just to name 2
will not build against newer ffmpeg's without modifying their source
code, or appending some ./configure options. I know there are others,
but can not remember them off the top of my head.


None of this is an issue with ffmpeg directly, but the 3rd party
developers' source code, and their lack of comments as to which
version they require :-/. Considering ffmpeg is an extremely fast
moving project, it's hard for anyone to keep up with.

Rather than having to have the latest and greatest for no other reason
than it's newer I tend to stick with the version that has the best
compatibility with other programs.

x264 has the same issues. There are known compile, and run time errors
with different revisions in 2008. Some of the options just flat out
don't work, depending on your CPU type, and 32bit vs 64bit. x264 is in
a constant state of flux at the current moment. I've found 20080301 to
work rather well, and have had numerous issues with anything previous,
and gave up trying from 20080315 - 200807xx. After 4 months and no
stable code base I've just stuck with the 20080301 release.
