I think this mean selected codec does not exist.

be sure to launch self-compiled against system's ffmpeg version of cin (you
can check libraries it links to by using ldd path_to_executable )

yeah, strange.

Can you
a) launch cin like LANG=C bin/cin

b) try to save video to somesimple location like /dev/shm/1.mp4
