Media Processing

Context

Media processing involves uploading, downloading, cataloging, transcoding, and archiving media materials, as well as storing, invoking, and managing audio and video data. Media processing has the following requirements on shared general-purpose file systems:

Media materials feature a high video bit rate and a large scale. A general-purpose file systems must be large enough in capacity and is easy to expand.
Acquisition, editing, and synthesis of audio and video data require stable and low-latency general-purpose file systems.
Concurrent editing requires general-purpose file systems to deliver reliable and easy-to-use data sharing.
Video rendering and special effects need to process small files frequently. The general-purpose file systems must offer high I/O performance.

SFS is a shared storage service based on general-purpose file systems. It features high-speed data sharing, dynamic storage tiering, as well as on-demand, smooth, and online resizing. These outstanding features empower SFS to meet the demanding requirements of media processing on storage capacity, throughput, IOPS, and latency.

For example, a TV channel has a large volume of audio and video materials to process. The work will be done on multiple editing workstations. The TV channel uses SFS to enable file sharing among the editing workstations. First, a file system is mounted to ECSs that function as upload workstations and editing workstations. Raw materials are then uploaded, through the upload workstations, to the general-purpose file system. In this way, the editing workstations concurrently edit the materials in the file system.

Configuration Process

Prepare the material files to be uploaded.
Log in to the SFS console and create a general-purpose file system to store the prepared files.
Log in to the ECSs that function as upload and editing workstations, and mount the general-purpose file system.
On the upload workstation, upload the material files to the general-purpose file system.
On the editing workstation, edit the material files.

Prerequisites

A VPC has been created.
ECSs that function as upload and editing workstations have been created and are in the created VPC.
SFS has been enabled.

Example Configuration

Log in to the SFS console.
In the upper right corner of the page, click Create File System.
On the page for creating a general-purpose file system, configure parameters as instructed.
After the configuration is complete, click Create Now.

Log in to the upload workstation and upload the material files to the general-purpose file system.
Log in to the editing workstation and edit the material files.
