http://ffmpeg.org/ffmpeg-devices.html#fbdev 
indicates that ffmpeg -f fbdev -i /dev/graphics/fb0 
should be used but I unfortunately cannot test here.

Concerning that x264 doesn't work at all, please test:
$ ffmpeg -f lavfi -i testsrc -pix_fmt yuv420p out.mov
If this doesn't work, we have to find out why.

If it works, please replace "-f lavfi -i testsrc" with 
the framebuffer input.
