(Completely unrelated: You don't have to install FFmpeg to use it.)

If 1.raw is indeed h263 video (as your original mail implies), 
either rename it to 1.h263 or use ffmpeg -f h263 -i out.raw, .raw 
now implies rawvideo (does anybody think this was a bad idea?), 
I don't think it is typically likely that .raw is h263.
