ApsaraVideo Media Processing:Intelligent production

Last Updated:Oct 25, 2024

The intelligent production feature is implemented based on Alibaba Cloud media AI technologies. The feature allows you to generate and process media content in various formats. It provides capabilities such as intelligent thumbnail, intelligent landscape-to-portrait, image matting, figure cutout, intelligent logo blurring, intelligent caption removal, caption extraction, chorus identification, and music rhythm identification. These capabilities improve the efficiency and quality of media content generation and processing.

Overview

Scenarios

  • Intelligent production of media and entertainment videos: The intelligent production feature allows you to efficiently generate and process video content such as logos, captions, and objects.

  • Video delivery to multiple terminals and platforms: The intelligent production feature allows you to convert the orientation of a video from landscape to portrait or vice versa. This allows videos to be played on different terminals and platforms and improves content distribution efficiency.

Capabilities

Limits

  • For more information about the supported regions, see Regions and endpoints.

  • For more information about the maximum number of jobs that an ApsaraVideo Media Processing (MPS) queue can concurrently process, see the "Limits" section of the Overview topic.

Before you begin

Make sure that the following operations are performed:

  • Create an MPS queue. For more information, see Create an MPS queue. If no MPS queue for intelligent thumbnail creation exists in the MPS queue list, create an MPS queue for intelligent thumbnail creation first.

  • Upload the video to be processed to OSS.

    • If you want to create a job, directly upload the video to OSS. For more information, see Upload a video.

    • If you want to create a workflow and automatically trigger the workflow, you must add media buckets and create a workflow before you upload the video. After you specify the input and output media buckets and upload a media file to the input media bucket, MPS receives a message about the upload and triggers the associated workflow. After the workflow is complete, the processed media file is uploaded to the output media bucket. For more information, see Add media buckets.

  • Optional. Enable the notification feature. If you want MPS to send notifications on jobs and workflows to MNS topics or queues, configure an MNS queue or topic as required. For more information, see Enable the notification feature for MPS jobs or workflows.

Create an intelligent production job in the MPS console

Note

You can create only intelligent thumbnail jobs or workflows in the MPS console. You can create other intelligent production jobs by calling API operations.

Create an intelligent thumbnail job

  1. Log on to the MPS console.

  2. In the top navigation bar, select a region from the drop-down list.地域

  3. In the left-side navigation pane, choose Tasks > Job Management.

  4. On the Tasks page, click the Intelligent Thumbnail tab. On the Intelligent Thumbnail tab, click Create Task.

  5. Configure the parameters that are described in the following table.

    Parameter

    Description

    Input File URL

    Click Select next to the Input File URL field. In the Select File dialog box, select a bucket from the Bucket drop-down list. Then, folders in the bucket are automatically displayed in the Path section. Select a file from a folder as the input file.

    Intelligent Thumbnail Pipeline

    Select an MPS queue for intelligent thumbnail creation from the drop-down list.

    Note

    If no MPS queue is displayed in the Intelligent Thumbnail Pipeline drop-down list, create an MPS queue for intelligent thumbnail creation. For more information, see Create an MPS queue.

    Output Path

    Click Select next to the Output Path field. In the Select Output Path dialog box, select a bucket from the Bucket drop-down list. Then, folders in the bucket are automatically displayed in the Path section. Select a folder as the output path.

    Note

    If the output path is the same as the input path and the output file name is different from the input file name, the input file is not overwritten by the output file. If the input file has the same name as the output file, you can configure OSS to prevent the input file from being overwritten. For more information, see Prevent objects from being overwritten by objects that have the same name. In this case, if the transcoded output file shares the same name as the input file, the output file fails to be written to the OSS bucket. We recommend that you do not specify a name that is the same as the name of the input file for the output file.

  6. Click Submit. The intelligent thumbnail job is created.

    After the intelligent thumbnail job is created, you can view the state and file path of the job on the Intelligent Thumbnail tab. You can also click the name of the job to view the job details, such as the input file and job configurations.

Create an intelligent production job by calling an API operation

image
  1. Create an intelligent production job.

    For media files such as videos, images, and audio files that have been uploaded to OSS, you can call the SubmitIProductionJob operation to create an intelligent production job. You can specify the intelligent production capability that you want to use by configuring the FunctionName parameter.

  2. Receive a callback notification.

    If you have configured a Simple Message Queue (formerly MNS) queue or topic to receive notifications, MPS sends a notification to the SMQ queue or topic after the intelligent production job is complete. For more information, see Receive notifications.

  3. Query the results of the intelligent production job.

    You can call the QueryIProductionJob operation to query the state and results of the intelligent production job by job ID.
