Hello,       I want the GOP structure after mpeg2video coding to be IBBPBBPBBPBB, but the GOP structure in the encoded out put file is IPBBPBBPBB. How do I set the coding parameters? The following is the command I run:
      ffmpeg.exe -i L:\input.mp4 -vcodec mpeg2video -g 12 -bf 2 -flags +cgop -sc_threshold 1000000000 -y L:\output.m2v
