This error message tell you that your ffmpeg/libav is old
(av_pix_fmt_descriptors missing from libavutil\pixdesc.h) and you need
to update it. But what is strange is that it should fail at
./configure time not at compile time. Did you made something between
configure and make (like updating sources or installing librayies)?
Also it can be problem with multiple versions of ffmpeg/libav headers
in different directories so during ./configure and make it looks in
different places. It is problematic to say anything more because you
didn't attach config.log file.
