Video Packaging Enables the Playback of Online Education Videos on Multiple Terminal Types

Scenarios

MPC can convert mainstream video formats to MP4 or HLS for multi-terminal compatibility, so that online education videos can be played regardless of terminal types and network conditions. For example, users can watch videos of online education platforms on mobile apps.

How It Works

Figure 1 Working principle

Restrictions

• Supported input formats: MP3, MP4, FLV, and TS
• Supported output formats: HLS and MP4

Procedure

1. Log in to the MPC console.
2. In the navigation pane, choose Media Processing > Packaging.
3. Click Create Task.
   Figure 2 Creating a packaging task
   

4. Configure task parameters by referring to Table 1.

   Table 1 Parameters

   Parameter	Description
   Where the source bucket is located	Region where the OBS bucket for storing the source video file is
   Bucket name	OBS bucket for storing the source video file
   Source File	Path for storing the source video file
   Output Region	Where the output bucket is located
   Output bucket name	OBS bucket for storing the packaged video file
   Output Path (Optional)	Path for storing the output file
   File Name (Optional)	Name of the packaged file
   Output Format	Format of the output file. Currently, only HLS and MP4 are supported.
   Segment Duration (s)	HLS segment length. This parameter is used only when Output Format is HLS. The value ranges from 2 to 10. Default value: 5

5. Click OK.
6. View the task status in the task list.

   When the task status changes to Completed, you can obtain the packaged file from the output path.

SDK Integration Example

For details about the packaging feature and its sample code, see Creating a Packaging Task.

SDK core code for education website developers to access MPC:

    ObsObjInfo input = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01").withObject("ok.flv");
    ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01").withObject("output");
    // Create a packaging request.
    CreateRemuxTaskRequest req = new CreateRemuxTaskRequest()
            .withBody(new CreateRemuxTaskReq().withInput(input).withOutput(output)
                    // Configure packaging parameters.
                    .withOutputParam(new RemuxOutputParam()
                            // Set the packaging format.
                            .withFormat("HLS")
                            // Set the HLS segment interval.
                            .withSegmentDuration(5)));
    // Send the packaging request.
    CreateRemuxTaskResponse rsp = initMpcClient().createRemuxTask(req);
    System.out.println(rsp.toString())
