I decode and re encode I frame of a movie file. when encode I frame, each I frame need a different qp value. How can qp parameter change after avcodec_open2(CodecCtx, codec, &options) ) ?
av_dict_set( &options, "qp" , x , 0 ) is used to set qp. If x264 parameter can't change after avcodec_open2 function, Can I close this encoder and open a new x264 encoder with a new parameter for next I frame?
