php实现阿里云视频合成_php合成视频

获取视频上传凭证，这个时候会产生一个“上传中”的空videoid，实际上是没有上传内容的；

通过获取到的uploadAuth/uploadAddress/videoId进行上传您本地的视频完成了2和3之后才会出现“正常”状态下的视频。

 

1：视频合成第一步创建云剪辑工程 

    /**
     * 使用AK&SK初始化账号Client
     * @param string $accessKeyId
     * @param string $accessKeySecret
     * @return Vod Client
     */
    public static function createClient($accessKeyId, $accessKeySecret){
        $config = new Config([
            // 您的AccessKey ID
            "accessKeyId" => $accessKeyId,
            // 您的AccessKey Secret
            "accessKeySecret" => $accessKeySecret
        ]);
        // 访问的域名
        $config->endpoint = "vod.cn-beijing.aliyuncs.com";
        $config->endpoint = "vod.cn-shanghai.aliyuncs.com";
        return new Vod($config);
    }    
 
 
    /**
     * 创建云剪辑工程
     */
    public static function cloudClip($info){
        $client = self::createClient("", "");
        $addEditingProjectRequest = new AddEditingProjectRequest([
            "title" => $info['Title'],
            'description' => $info['Description'],
            'coverURL' => $info['CoverURL'],
        ]);
        return $client -> addEditingProject($addEditingProjectRequest);
    }
 
    $info = [
            'Title' => 'zjzj',
            'Description' => '123456789',
            'CoverURL' => 'http://api.cloudtanke.com/static/images/login_logo.png',
            'FileName' => 'zjzj.mp4',
        ];
 
    $cloudClip = self::cloudClip($info);#创建云剪辑工程

2：第二步 获取视频上传地址和凭证  （如果报错:The storageLocation does not exist 的话 ， 请查看服务地址。改成上海试试）

• 该接口不会真正上传视频文件，您需要获得上传地址和凭证后，对其进行Base64解码，再调用OSS SDK将视频文件上传至指定的bucket中。详细操作，请参见基于OSS原生SDK上传视频到点播。
• 如果视频上传凭证失效（有效期为3000秒），请调用刷新视频上传凭证接口重新获取上传凭证。 

    /**
     * 获取视频上传地址和凭证
     */
    public static function createVideo($info){
        $client = self::createClient("", "");
        $createUploadVideoRequest = new CreateUploadVideoRequest([
            "fileName" => $info['FileName'],
            "title" => $info['Title'],
        ]);
        return $client->createUploadVideo($createUploadVideoRequest);
    }
 
    $videoId = self::createVideo($info);

3：第三步 查看文档 基于OSS原生SDK上传视频到点播 

        $uploadAuth = json_decode(base64_decode($videoId->body->uploadAuth),true);
        $uploadAddress = json_decode(base64_decode($videoId->body->uploadAddress),true);
 
        $localFile = $_SERVER['DOCUMENT_ROOT'].'/uploads/20210409/eb0b8db0e74c61d11529613e3a3c5f2d.mp4';
 
        $ossClient = self::initOssClient($uploadAuth,$uploadAddress,$localFile);#基于OSS原生SDK上传视频
 
    /**
     * 基于OSS原生SDK上传视频
     * @param $uploadAuth
     * @param $uploadAddress
     * @param $localFile
     * @return null
     * @throws \OSS\Core\OssException
     */
    public static function initOssClient($uploadAuth, $uploadAddress,$localFile) {
        $ossClient = new OssClient($uploadAuth['AccessKeyId'], $uploadAuth['AccessKeySecret'], $uploadAddress['Endpoint'],
            false, $uploadAuth['SecurityToken']);
        $ossClient->setTimeout(86400*7);    // 设置请求超时时间，单位秒，默认是5184000秒, 建议不要设置太小，如果上传文件很大，消耗的时间会比较长
        $ossClient->setConnectTimeout(10);  // 设置连接超时时间，单位秒，默认是10秒
 
        //return $ossClient->uploadFile($uploadAddress['Bucket'], $uploadAddress['FileName'], $localFile);
        return $ossClient->multiuploadFile($uploadAddress['Bucket'], $uploadAddress['FileName'], $localFile);
    }

4：第四步 视频合成 

合成视频   视频+音频   音频上传如第二步操作一样     

$result这个数组里面包含很多个二维数组，一维数组不会报错，但是会上传不成功

        $result = [
            "VideoTracks" => [
                [
                    "VideoTrackClips" =>[
                        [
                            "MediaId" => $videoId->body->videoId,
                            "Effects" => [
                                [
                                    "Type" => "Volume",
                                    "Gain" => "0"
                                ]
                            ]
                        ]
                    ]
                ],
            ],
            "AudioTracks" => [
                [
                    "AudioTrackClips" =>[
                        [
                            "MediaId" => $audioId->body->videoId,
                            "TimelineIn" => 5
                        ]
                    ]
                ]
            ]
        ];
 
        $resultJson = json_encode($result);
 
        $arr=self::videoPost($cloudClip->body->project->projectId,$resultJson);#视频合成
 
    /**
     * 视频合成
     */
    public function videoPost($projectId,$result){
        $client = self::createClient("", "");
        $produceEditingProjectVideoRequest = new ProduceEditingProjectVideoRequest([
            'projectId' => $projectId,
            'timeline' => $result
        ]);
        return $client->produceEditingProjectVideo($produceEditingProjectVideoRequest);
    }
 
 
 
 
 

完结！！！

 

补充：

1：use的路径一定要准确！！！！

use AlibabaCloud\SDK\Vod\V20170321\Models\AddEditingProjectRequest;
use AlibabaCloud\SDK\Vod\V20170321\Models\CreateUploadVideoRequest;
use AlibabaCloud\SDK\Vod\V20170321\Models\GetPlayInfoRequest;
use AlibabaCloud\SDK\Vod\V20170321\Models\GetVideoPlayAuthRequest;

use AlibabaCloud\SDK\Vod\V20170321\Vod;
use app\common\controller\Frontend;

use OSS\OssClient;

2：SDK包  安装新本SDK 使用composer可
