Creating a Packaging Task

Function

This API is used to create a packaging task. Packaging is to convert the container format of audio and video files without changing the resolution and bitrate. Ensure that an input media file is stored in an OBS bucket in the same region as MPC and the permission for accessing the OBS bucket has been granted to MPC.

Calling Method

For details, see Calling APIs.

URI

POST /v1/{project_id}/remux

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Project ID. For details about how to obtain the project ID, see Obtaining a Project ID .

Request Parameters

Table 2 Request header parameters

Parameter

Mandatory

Type

Description

X-Auth-Token

No

String

User token

The token can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is the user token.

Authorization

No

String

Authentication information. This parameter is mandatory when AK/SK-based authentication is used.

X-Project_Id

No

String

Project ID. This parameter is mandatory when AK/SK-based authentication is used. It is same as the project ID in path parameters.

X-Sdk-Date

No

String

Time when the request is sent. This parameter is mandatory when AK/SK-based authentication is used.
Table 3 Request body parameters

Parameter

Mandatory

Type

Description

input

No

ObsObjInfo object

Input file information.

NOTE:

Videos in M3U8 format cannot be converted to animated GIFs, perform synchronous parsing or snapshot capturing.

output

No

ObsObjInfo object

Output file information

user_data

No

String

Custom user data

output_param

No

RemuxOutputParam object

Output parameter.
Table 4 ObsObjInfo

Parameter

Mandatory

Type

Description

bucket

Yes

String

OBS bucket name

location

Yes

String

Region where an OBS bucket is located. It must be the same as the region where MPC is deployed.

object

Yes

String

OBS object path, which complies with the OSS Object definition.

  • If this parameter is used for an input, an object must be specified.

  • If this parameter is used for an output, only the directory for storing the output needs to be specified.

file_name

No

String

File name

  • If this parameter is specified, the output object name is object/file_name.

  • If this parameter is not specified, the output object name is object/xxx, where xxx is specified by MPC.

When it is used as the output file name:

  • Specifies the name of the output file. This parameter is valid for packaging.

  • If the output file name needs to be specified during transcoding, use the output_filenames parameter.

  • This parameter is valid for parsing. If a file name is specified during parsing, the parsing parameters are written to the specified file name and the file metadata is obtained through the query API response in JSON format.

  • This parameter is invalid for snapshot capturing.

  • This parameter is invalid for conversion into animated GIFs.
Table 5 RemuxOutputParam

Parameter

Mandatory

Type

Description

format

No

String

Output file format. Possible values:

  • HLS

  • MP4

segment_duration

No

Integer

Segment duration. This parameter is used only when format is HLS.

The value ranges from 2 to 10.

Default value: 5

Unit: second

NOTE:

remove_meta

No

Boolean

Whether to remove the custom metadata of the input media from the output media. Default value: false.
