Uploading Media Files

Notes

MPC only processes media files stored in an OBS bucket whose region is the same as MPC. If you want to use MPC in CN North-Beijing 4, then the bucket that stores media files must be in CN North-Beijing 4 as well.

Procedure

1. Log in to the OBS console.
2. Click Create Bucket.
3. On the displayed page, enter the bucket name and select the storage class and bucket policy based on your needs.
4. Click Create Now.
   If the input and output files are stored in the same bucket, create one bucket. Otherwise, create two buckets as the input and output buckets respectively.

   Table 1 Storage classes

   Storage Class	Application Scenario
   Standard	Stores frequently accessed (multiple times per month) data such as small and essential files that require low latency.
   Infrequent Access	Stores infrequently accessed (once per month) data that requires low latency.
   Archive	Stores rarely accessed (once per year) data.

   Table 2 Bucket policies

   Bucket Policy	Description
   Private	Only the bucket owner can read, write, and delete objects in the bucket.
   Public Read	Any user can read objects in the bucket. Only the bucket owner can write and delete objects in the bucket.
   Public Read and Write	Any user can read, write, and delete objects in the bucket.

   

   • Select a region where you want MPC to do the transcoding. If you use MPC in CN North-Beijing 4, then you need to create a bucket in CN North-Beijing 4.
   • If input files and output files are stored in different buckets, you are advised to set the storage class of the input bucket to Infrequent Access and that of the output bucket to Standard.
