+ /* BUILD 29 adds support for multi-threaded encoding while BUILD 49 (r543)
+ also adds support for threads = 0 for automatically selecting an optimal
+ value (cores * 1.5) based on detected CPUs. Default behavior for x264 is
+ threads = 1, however VLC usage differs and uses threads = 0 (auto) by
+ default unless ofcourse transcode threads is explicitly specified.. */
