Xface

Reading the xfaces with the audio to make a video file (probably better ways to do this).

ffmpeg -c:v xface -f image2 -i xface-%05d.bmp -f nut - | ffmpeg -i - -i audio.wav -map 0 -map 1 -c:v rawvideo -s 48x48 -pix_fmt monow -c:v ffv1 -c:a pcm_s16le xface-48x48.mov

I then had a file that showed what xface looks like in video form, but if I increased the size of the video from 4848 in my QuickTime player then the video would blur and deteriorate at larger sizes.
