编码参数
ffmpeg -i h264_4kp30_41s.ts -c:v libx265 -b:v 2.5M -profile main -level 4.2 -tier main -s 1920x1080 -crf 18 -keyint_min 12 -g 60 -sc_threshold 0 out.ts
尝试过其他参数,效果基本一致
ffmpeg -i h264_4kp30_41s.ts -c:v libx265 -preset medium -x265-params "crf=22:qcomp=0.8:aq-mode=1:aq_strength=1.0:qg-size=16:psy-rd=0.7:psy-rdoq=5.0:rdoq-level=1:merange=44" -s 1920X1080 out.ts
请问应该如何配置参数
另外:
FFMPEG libx265 官网说明书中,很多命令都在cmd中无法识别,如
--input-depth <integer>YUV only: Bit-depth of input file or stream Values: any value between 8 and 16. Default is internal depth. CLI ONLY --frames <integer>
