Regarding to the "redundant operations" in liavcodec, for example, the zerosleft decoding can be merged with the dequantization instead of two loop
What are you talking about with the zerosleft decoding? It is merged with dequantization, and is not two loops (and I don't think this was done recently either).

Would you like to point me to a specific case so I can fix it rather than complaining?

Any suggestion for improved context calculation performance will probably allow me to make x264's RDO faster as well.

Same with the actual CABAC decoding--are you suggesting that there is a better way to organize LUTs/similar that results in better faster arithmetic decoding than what LAVC already has?
