If you just want one frame:
ffmpeg -i <input> -vframes 1 -pix_fmt bgr8 -y output.bmp
If you want lots of output frames:
ffmpeg -i <input> -pix_fmt bgr8 yo%03d.bmp

I have been having trouble converting a video to 8 bit BMP frames. How to convert it using FFmpeg? or have suggestion software to do that?
