(methods 5 and 6 are still untouched). Methods #0 and #1 got much faster Method #2 gets vastly improved in quality Method #3 is noticeably faster for little lower quality Method #4 (default) is 10-20% faster for comparable quality + update the internal doc about the methods' tools. Example of speed difference: Time to encode picture: Method | Before | After -m 0 | 1.272s | 0.517s -m 1 | 1.295s | 0.623s -m 2 | 2.217s | 0.834s -m 3 | 2.816s | 2.243s -m 4 | 3.235s | 3.014s -m 5 | 3.668s | 3.654s -m 6 | 8.296s | 8.235s Change-Id: Ic41fda5de65066b3a6586cb8ae1ebb0206d47fe0 |
