I want to use 2-pass rate control in the HEVC encoder reference code but I do not know if there is a configuration setting to do it. My goal is to encode an original sequence in the 1st-pass rate control and encode a filtered sequence of the original sequence in the 2nd-pass.
I see this can be done in FFmpeg and x265, but giving two different input videos (original and filtered) to the encoder, does it still even make sense? Any ideas on how to do it in the HEVC encoder/x265 or any comments would be appreciated.
