Workflows can include tasks such as transcoding, screenshot taking, animated image generating, moderation, content recognition, content analysis, and watermarking.

Creating a Workflow

1. Log in to the MPS console and click Workflow Management.
2. Click Create Workflow to enter the workflow creation page and set the workflow name, trigger bucket, trigger directory, output bucket, output directory, event notifications and tasks. For detailed instructions, please see workflow configuration.
   
   The table below lists the information needed to configure a workflow.

   Item	Required	Description
   Workflow name	Yes	Max 128 characters; supports Chinese characters, letters, digits, underscores, and hyphens. Example: "MPS"
   Trigger bucket	Yes	Select a bucket created under the current `APPID`. After the workflow is enabled, videos uploaded to this bucket will be processed automatically.
   Trigger directory	No	A string that ends with (/). If it is left empty, the workflow will be applied to all directories under the selected trigger bucket.
   Output bucket	Yes	By default, the output bucket is the same as the trigger bucket. You can also select a bucket in the same region under the same `APPID`. After a workflow is executed, the processed videos will be stored in this bucket.
   Output directory	No	A string that ends with (/). If it is left empty, the output directory will be the same as the trigger directory.
   Event notifications	No	Disabled by default. For detailed instructions on how to configure event notifications, please see callback configuration below. To enable CMQ event notifications, you need to activate CMQ and create a model. After CMQ event notifications are enabled, the specified CMQ will receive notifications about video processing events.
   Configuration items	Yes	From transcoding, screenshot taking, animated image generation, moderation, content recognition, and content analysis, select at least one task for configuration. For details, please see task configuration below.

   Callback Method	Configuration
   CMQ callback	CMQ model: queue model by default CMQ zone: Guangzhou, Shanghai, Beijing, Shanghai Finance, Shenzhen Finance, Hong Kong (China), Chengdu, North America, or West US Queue name: a custom value
   SCF callback	Click **Go to SCF Console** to configure the callback in the SCF console. For detailed instructions, please see MPS Task Callback Notification. The configuration applies to all workflows and is not saved specifically by one workflow.

Event Notifications

1. Receiving event notifications via CMQ

• Event notifications are disabled by default. To receive notifications via CMQ, click the toggle next to Enable Event Notifications, select queue or topic model for CMQ Model, and set the model name and region. MPS event notifications will be sent to the specified queue or topic.

• You can receive event notifications via CMQ only after you activate the CMQ service and create a queue or topic model. For more information, please see CMQ > Getting Started.

2. Receiving event notifications via SCF

SCF allows quick handling of the event notifications generated by MPS. The figure below shows the data flow.

Events are pushed to SCF by the MPS trigger and are handled by serverless functions.

Use cases

CLS can deliver the data in log topics to SCF via an MPS log trigger to enable operations such as notification sending, status monitoring, and alarm handling.

Note：

You will incur a cost for delivering data to SCF. For details, please see SCF > Billing Overview.
