How to send a ffmpeg stream to the framebuffer /dev/fb0?

For instance, how to send the webcam output to the framebuffer?

I am looking for an equivalent of this mplayer command but using ffmpeg exclusively:

mplayer -ov fbdev2 -tv driver=v4l2 device=/dev/video0 tv://

P. S.: I don't wat to pipe the output of ffmpeg to mplayer

There is a lot of misinformation on the web about this not being possible, however, it most definitely is possible. Note, you may need to adjust the -i and -pix_fmt a bit for your situation.

ffmpeg -i /dev/video0 -pix_fmt bgra -f fbdev /dev/fb0

Also note, the user executing this must have privileges to write to the framebuffer (i.e. root).

This is not possible with solely ffmpeg. ffmpeg is a very fast video and audio converter, whilst mplayer is a video player (which involves video decoding, of course).
