I was interested in this problem some time ago. I even wrote an algorithm and 
added it to FFmpeg for tests.?It calculates and prints how much the mjpeg 
file would be decreased (you only need to use tables generated by it to 
compress the file). Difference was often small (3-5%), so I put it off, but I 
was busy. In my opinion it's a good idea to try to use many Huffman tables 
for one file. I enclose file which may be useful.
