I stared down the avcodec.h file and it blinked. I can grep for
'LIBAVCODEC_VERSION_{MAJOR,MINOR,MICRO}', which seem to be new for
this versioning scheme. Their values are plain ints, from which I
will construct a version string in our time-honored fashion.
Also, your great idea (sent to me in private email) for using -I
/path/to/avformat and -I /path/to/avcodec won't work, because
avcodec.h immediately #includes <avutils/avutils.h>, so it's parent
has to be on the include path *anyway*. Any sane installation or
packaging should have them all in the same parent, because that's how
ffmpeg installs them. They'll either all be in .../ffmpeg, or they'll
be in .../{libavcodec,libavformat,libavutils}.
