Adds modeled functions to decide the qp for altref frames in constant q mode similar to other functions in use in bitrate mode. Also turns on the constrained quality mode (end-usage=2) option which was turned off before. Basic testing shows the mode works in principle, to cap bitrate to the target-bitrate specified, while allowing lower bitrate depending on the cq-level specified. The mode will need to be improved over time. Results for constant quality vs bitrate control mode: derfraw300/fullderfraw: +3.0% at constant quality over bitrate control. fullstdhdraw: +4.341% stdhdraw250: +5.361% Change-Id: If5027c9ec66c8e88d33e47062c6cb84a07b1cda9
