[x264-devel] bit allocation algorithms among frames

[Tuukka Toivonen]

Hi, stumbled some time ago into this paper:
http://foulard.ee.cornell.edu/publications/sermadevi_dcc2005.pdf
"When is Bit Allocation for Predictive Video Coding Easy?"

On page 7, it describes a "Non-backtracking Coordinate SD Algorithm"
(SD=steepest descent) which appears to be very simple to implement
(albeit a little bit slow). If someone is looking some experiments to do 
with x264, this would be a nice project. I'd very much like to see the 
results (especially how QP varies between frames) but don't have time for 
this project.

I did something similar, my paper is here:

(I could provide the source code too, but its very messy)
