Choose one of:

c_enc->profile = FF_PROFILE_H264_BASELINE;
c_enc->profile = FF_PROFILE_H264_CONSTRAINED_BASELINE;
c_enc->profile = FF_PROFILE_H264_MAIN;
c_enc->profile = FF_PROFILE_H264_EXTENDED;
c_enc->profile = FF_PROFILE_H264_HIGH_10;
c_enc->profile = FF_PROFILE_H264_HIGH_422;
c_enc->profile = FF_PROFILE_H264_HIGH_444;
