You probably missed the link yesterday:
There is "preset" and "tune" options in ffmpeg, you can set them that way:
av_opt_set(codecContex->priv_data, "preset", "ultrafast", 0);
av_opt_set(codecContex->priv_data, "tune", "zerolatency", 0);
where codecContex is AVCodecContext.
For other x264 options that isn't presented in ffmpeg you could use
Regarding P-frames, I thought you wanted to remove them, too.
