音频插入

压缩视频

设置关键帧（主要用于视频拼接中间有卡顿现象）

	 /**     * 设置关键帧     * @param $vIDeo_url     * @param $object_name     * @return array     * @author: xiao     * @Date: 2021/4/27  17:05     */    public function vIDeoSetKey($vIDeo_url, $object_name)    {        $ffmpeg_exec = '/usr/local/ffmpeg/bin/ffmpeg -i '.$vIDeo_url.' -threads 2 -preset ultrafast -g 1 -keyint_min 2  '.$this->vIDeo_path.$object_name.'

获取视频信息

	 /**     * 获取视频信息     * @param $vIDeo_url     * @return array|string[]     * @author: xiao     * @Date: 2021/6/10  15:54     */    public function getVIDeoInfo($vIDeo_url)    {        $arr = [];        $ffmpeg_exec = '/usr/local/ffmpeg/bin/ffprobe -i '.$vIDeo_url.' -preset ultrafast  2>&1';//        $vIDeo_info = shell_exec($ffmpeg_exec);        exec($ffmpeg_exec,$info,$code);        if (empty($info)){            $this->data['code'] = -1;            $this->data['msg'] = '获取视频信息失败';            return $this->data;        }        /**         * 获取视频信息开始         */        //分辨率        if (isset($info[18])){            $temp_ratio = explode(',',$info[18]);            $arr['ratio'] = isset($temp_ratio[2])?trim($temp_ratio[2]):'1280x720';        }        return $arr;    }
