[FFmpeg-user] Need ffmpeg command options for converting MPEG2 GOP structure

[DANIEL LAM]

Dear ffmpeg,

I am new to ffmpeg. I have a MPEG2, 1080i, 29.97fpstransport stream. It has closed GOP structure of I0 P3 B1 B2 P6 B4 B5 P9 B7 B8P12 B10 B11.  I need to convert the GOPto I0 B0 B1.

 What is the ffmpeg cli command options to do the conversion?

 Thanks much for your help.

 Daniel
