截图

更新时间:

视频截图是指对视频截取指定时间、指定尺寸的图片,用于生产视频封面、雪碧图、播放器进度条缩略图等场景,截图作业支持指定时间点、时间间隔、截图数量、类型以及是否拼图等。您可以通过媒体处理控制台、API或SDK提交截图作业。本文提供了媒体处理PHP SDK截图模块相关功能的API调用示例。

前提条件

使用前请先安装及完成PHP SDK相关配置,详细信息,请参见前言。更多SDK及API调用示例,请参见OpenAPI

提交截图作业

调用SubmitSnapshotJob提交截图作业,接口参数和返回字段详细信息请参见提交截图作业,调用示例如下:

<?php
namespace AlibabaCloud\SDK\Sample;

use AlibabaCloud\SDK\Mts\V20140618\Mts;
use AlibabaCloud\Darabonba\Env\Env;
use AlibabaCloud\Tea\Tea;
use AlibabaCloud\Tea\Utils\Utils;
use AlibabaCloud\Tea\Console\Console;

use Darabonba\OpenApi\Models\Config;
use AlibabaCloud\SDK\Mts\V20140618\Models\SubmitSnapshotJobRequest;


class Sample {

    private $pipelineId = "<PipelineId>";
    private $templateId = "S00000001-100020"; #转码模板ID,按需配置
    private $ossLocation = "<OssLocation>";
    private $bucket = "<bucket name>";
    private $oss_input_object  = "input.mp4"; 
    private $oss_output_object  = "output_{Count}.jpg";

    /**
     * @param string $accessKeyId
     * @param string $accessKeySecret
     * @param string $regionId
     * @return Mts
     * 正式环境下 建议 protocol = "HTTPS";
     */
    public static function createClient($accessKeyId, $accessKeySecret, $regionId){
        $config = new Config([]);
        $config->accessKeyId = $accessKeyId;
        $config->accessKeySecret = $accessKeySecret;
        $config->regionId = $regionId;
        $config->protocol = "HTTP";
        return new Mts($config);
    }

    /**
     * @return void
     */
    public static function main(){
        $sample = new Sample;
        $client = self::createClient(Env::getEnv("ALIBABA_CLOUD_ACCESS_KEY_ID"), Env::getEnv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"), 'cn-shanghai');
        $request = new SubmitSnapshotJobRequest([
            "input" => json_encode(array(
                'Location' => $sample->ossLocation,
                'Bucket' => $sample->bucket,
                'Object' => urlencode($sample->oss_input_object))
            ),
            "snapshotConfig" => $sample->snapshotConfig(),
            "pipelineId" => $sample->pipelineId,
        ]);
        $response = $client->submitSnapshotJob($request);
        Console::log(Utils::toJSONString(Tea::merge($response->body)));
    }


    function snapshotConfig() {
        $outputfile = array(
            'Location' => $this->ossLocation,
            'Bucket' => $this->bucket,
            'Object' => urlencode($this->oss_output_object));
        $snapshotConfig['OutputFile'] = $outputfile;
        $snapshotConfig['Time'] = 2;
        $snapshotConfig['Num'] = 10;
        $snapshotConfig['Interval'] = 20;
        return json_encode($snapshotConfig);
    }

}
$path = __DIR__ . \DIRECTORY_SEPARATOR . '..' . \DIRECTORY_SEPARATOR . 'vendor' . \DIRECTORY_SEPARATOR . 'autoload.php';
if (file_exists($path)) {
    require_once $path;
}
Sample::main();

查询截图作业

调用QuerySnapshotJobList查询截图作业,接口参数和返回字段详细信息请参见查询截图作业,调用示例如下:

<?php
namespace AlibabaCloud\SDK\Sample;

use AlibabaCloud\SDK\Mts\V20140618\Mts;
use AlibabaCloud\Darabonba\Env\Env;
use AlibabaCloud\Tea\Tea;
use AlibabaCloud\Tea\Utils\Utils;
use AlibabaCloud\Tea\Console\Console;

use Darabonba\OpenApi\Models\Config;
use AlibabaCloud\SDK\Mts\V20140618\Models\QuerySnapshotJobListRequest;


class Sample {

    /**
     * @param string $accessKeyId
     * @param string $accessKeySecret
     * @param string $regionId
     * @return Mts
     * 正式环境下 建议 protocol = "HTTPS";
     */
    public static function createClient($accessKeyId, $accessKeySecret, $regionId){
        $config = new Config([]);
        $config->accessKeyId = $accessKeyId;
        $config->accessKeySecret = $accessKeySecret;
        $config->regionId = $regionId;
        $config->protocol = "HTTP";
        return new Mts($config);
    }

    /**
     * @return void
     */
    public static function main(){
        $sample = new Sample;
        $client = self::createClient(Env::getEnv("ALIBABA_CLOUD_ACCESS_KEY_ID"), Env::getEnv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"), 'cn-shanghai');
        $request = new QuerySnapshotJobListRequest([
            "snapshotJobIds" => "72dfa5e67974c736******"
        ]);
        $response = $client->querySnapshotJobList($request);
        Console::log(Utils::toJSONString(Tea::merge($response->body)));
    }

}
$path = __DIR__ . \DIRECTORY_SEPARATOR . '..' . \DIRECTORY_SEPARATOR . 'vendor' . \DIRECTORY_SEPARATOR . 'autoload.php';
if (file_exists($path)) {
    require_once $path;
}
Sample::main();
