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

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));
