I've only ever compiled and installed FFmpeg myself, but it always puts its headers into ${PREFIX}/ffmpeg. Hence, when a C file includes these headers it should do e.g. #include <ffmpeg/avformat.h>. However lib/ogsf/gsd_img_mpeg.c includes files directly without the ffmpeg/ prefix. Is this valid on any common Linux distributions - are the FFmpeg header files directly in /usr/include instead of /usr/include/ffmpeg? If not, I think we should change it and the configure check so they work properly, i.e. no special value is required to be given for --with-ffmpeg-includes if they've been installed in the standard location.
Looks like a similar thing could be said for MySQL include files and db/drivers/mysql/globals.h. I'm almost sure there was a discussion about something like this with PostgreSQL a few years ago - but in that case IIRC it was PostgreSQL's naming convention, rather than GRASS that was broken.
