laravel ffmpeg 转码

先安装php拓展

        } catch (\Exception $e) {
            Log::channel('video')->error('错误:'.$e->getMessage());
        } finally {
            $this->result = $this->output;
            Log::channel('video')->info('转换成功:'.public_path().$this->output);
        }
    }
}

 

转码参数由setAdditionalParameters 方法写入

之前采用exec 可以直接执行 但是无法看到任务进度，所以引入第三方扩展

$this->output 为定义的输出文件名，这里指定的是m3u8格式
