prerequisite

Get the project ID of the task area where you need to create a screenshot (Get Project ID).

Clarify the information of the area where the screenshot task needs to be created, and obtain the Endpoint of the area (obtained by the area and terminal node).

Call the OBS Create Bucket API to create an OBS bucket for storing screenshot files, and then call the OBS Upload Object API to store video files to be captured in the OBS bucket.

operation steps

Step 1: Get the user token. When used for MPC interface, authentication is performed.

Get username, password, domainname and projectname on the My Credentials page, and call the following interface to get Token.

POST https://iam.cn-north-4.myhuaweicloud.com/v3/auth/tokensContent-Type: application/json{ "auth": { "identity": { "methods": [ "password" ], "password": { "user": { "name": "username", //username. "password": "password", //user login password. "domain": { "name": "domainname" //The name of the user's account. } } } }, "scope": { "project": { "name": "projectname" //project name. } } }}

As shown in the figure, the information in the red box is to obtain the user Token.

Step 2: Create Screenshot Task

Send a POST request.

POST：https://{endpoint}/v1/{project_id}/thumbnails

2. Add "X-Auth-Token" to the request message header, and set the value to the acquired user token.

3. The parameters passed into the Request Body are as follows:

{"input": { "bucket": "example-bucket", "location": "region01", "object": "/mpc/input/sample.MP4"},"output": { "bucket": "example-bucket", "location": "region01", "object": "/mpc/output/ "},"tar": 1,"thumbnail_para": { "type":"DOTS", "dots":[2,4,6,8,10], "format":0, "aspect_ratio":1, "max_length":480 } }

4. After the request response is successful, feedback the screenshot task ID.

{ "task_id": "2081"}

Step 3: Query the execution of video screenshots

1. Send a GET request.

GET：https://{endpoint}/v1/{project_id}/thumbnails? task_id=2081

2. Add "X-Auth-Token" to the header of the request message, and set the value to the acquired user Token. After the request is successfully responded, the details of the video screenshot are returned.

After the screenshot is completed, the captured images are transferred to the created OBS bucket, and then the screenshot is reviewed as the image content. OK!
