[self.currentTime mas_makeConstraints:^(MASConstraintMaker *make) {
    make.left.equalTo(self->_cover).offset(10);
    make.centerY.equalTo(self->_btnFullScreen);
}];

what result do you expect? What is the error message actually seen?

the first time loading sound can correspond to the video picture
