[x265] [PATCH] feature: --threaded-me

[Shashank Pathipati]

Threaded Motion Estimation is a feature which uses a dedicated thread pool to pre-compute motion estimation and evaluate PU combinations for CTUs in parallel. It relaxes inter-frame CTU dependencies to increase parallelism, which can reduce compression efficiency. Recommended on many-core CPUs when encode speed is prioritized over compression efficiency. If VBV options are enabled, Threaded ME is automatically disabled and a warning is emitted.

This feature is implicitly disabled when no thread pool is present.

--threaded-me provides speedups on many-core CPUs, accompanied by a compression efficiency loss.
