Build deps: Enable SSE optimization for FFmpeg The description is self-explanatory: enable SSE optimizations in the FFmpeg library. They were disabled from the very beginning of the dependency builder, possibly due to portability concerns. FFmpeg does perform runtime check for available CPU microarchitectures, so the codecs will still run on older hardware, but they will run way faster on newer hardware. For example, re-encoding 3405 2560x1376 frames on Xeon E5-2699 V4 CPU went down from 313sec to 210.
