Overview

Cloud Infinite provides a comprehensive and convenient media processing mechanism. Through this mechanism, various types of processing operations can be performed on media objects stored in COS.
The media processing mechanism is divided into the following methods:
Method
Category
Description
Submit tasks via raw parameters
Persistent processing
Submit a media processing task and set the required parameters for media processing task when submitting the task.
Submit tasks via template setting
Persistent processing
Set the processing template before submitting a media processing task and select the required template when submitting the task.
Workflow processing
Persistent processing
Combine different task types into a workflow. After configuring and enabling the workflow, files uploaded to COS will automatically trigger the workflow processing process.
Batch processing
Persistent processing
Perform batch processing on existing data in COS. The processing method is similar to task submission. After confirming the data scope and processing type that need to be processed, submit a batch task.
Synchronous task
Synchronous processing
Add media processing parameters after the URL of the media object.

Submitting Tasks via Raw Parameters

You can flexibly configure the required parameters for media processing task for each submission.
Note:
When submitting tasks via raw parameters, there is no need to set a template.
