The original video was 1920x1080 and this screen is 176x220 so I rotated it anti-clockwise and resized it to 220x124 to keep the aspect ratio the same but make best use of the screen. The "transpose=2" does the anti-clockwise rotation.
# First install ffmpeg if you haven't already sudo apt-get -y install ffmpeg # Now convert ("experimental" was flagged as required for this h264 movie - try without first) avconv -i Jeremy.mp4 -s 220:124 -vf transpose=2 -strict experimental j.mp4
Then to play it, make sure to pick the correct framebuffer device - mine is /dev/fb1:
mplayer -vo fbdev2:/dev/fb1 j.mp4
