Hi, The patch has implemented VBV methods for x265. 1.add parameter "vbv-maxrate" "vbv-bufsize" "vbv-init" into cmd line; 2.implement vbv methods. The patch doesn't include vbv algorithms based on lookahead, it will be added in future. And perhaps CU level ratecontrol will also be added later. I have tested with the following options, x265.exe --input BQMall_832x480_60.yuv -o BQMall_832x480_60_vbv.hevc --recon BQMall_832x480_60_vbv.yuv --fps 60 --input-res 832x480 --keyint 30 --frames 600 --rd 1 --crf 28 --vbv-maxrate 600 --vbv-bufsize 600 -F 5 --b-adapt 1 --bframes 3 --log 2 It works relatively OK. With more strict condition like crf=20、smaller buffersize etc., the encoder will underflow or overflow, maybe it need lookahead vbv or CU level ratecontol to deal with. I tested with local clips, it need more careful tests any questions, please let me know, thanks!
