Creating a Video Parsing Task

You can create a task to parse video metadata by creating an MPC client instance and configuring related parameters.

Prerequisites

  • You have purchased OBS and uploaded source videos for media processing in the region of MPC (for example, CN North-Beijing4) by referring to Uploading Media Files.
  • You have obtained the authorization for MPC to access cloud resources by following the instructions provided in Authorizing Access to Cloud Resources.

Core Code

  1. Create a video parsing task.
    Configure input video file parameters. If necessary, you can save the metadata file in a specified path.

    // Set the paths of the input and output files.
ObsObjInfo input = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01").withObject("ok.mp4");
ObsObjInfo output = new ObsObjInfo().withBucket("mpc-east-2").withLocation("region01").withObject("output");
// Create a video parsing request.
CreateExtractTaskRequest req = new CreateExtractTaskRequest()
        .withBody(new CreateExtractTaskReq().withInput(input));
// Send the request.
CreateExtractTaskResponse rsp = initMpcClient().createExtractTask(req);
// Print the result.
System.out.println("CreateExtractTaskResponse=" + JsonUtils.toJSON(rsp));
