Hi, recently, I did some comparison between 1 pass ABR and 2 pass, obviously, 2 pass almostly uses less bit rate to produce more psnr, my issue is if I can use 2 pass method, when I want to implement real time encoding, certainly, it is not really real time, 10 or more second latency can be allowed, and my assumption is one pass generates stat in real time, meanwhile another pass encodes later than 10 seconds based on the stat, can X264 implement it? or somebody has considered it or implemented it based on X264? thanks
