[FFmpeg-user] CLOSED GOP STRUCTURE

[andrea velrasquiña]

Hello,

I am trying to encode a h264 file with a closed GOP structure and reference
frames on 2 , this using the following code, but it by default it removes
the constant bitrate and the reference frames end up in 4 instead of 2.

Can some one please help me.
Thank you,
