Increasing parallel throughput

[Former user]

As movies are more wide than high. Wouldn't it be better to encode columns instead of rows to increase parallelity ?

[Pradeep Ramachandran]

HEVC as a standard doesn't allow to encode columns in parallel. In addition to WPP (which is row-level parallelism), we also implement frame-level parallelism, and slice-level parallelism. The HEVC standard also recommends tile parallelism, but that isn't supported yet by x265; you are encouraged to submit patches for this :-).
