AddMedia - ApsaraVideo Media Processing - Alibaba Cloud Documentation Center

Adds a media file.

Operation description

You can call this operation to process videos that are uploaded to Object Storage Service (OSS) but not processed. This way, you do not need to upload the videos to OSS again. If you have configured media workflows, OSS automatically notifies ApsaraVideo Media Processing (MPS) when a media file is uploaded to OSS. MPS automatically finds the corresponding workflow in the Active state based on the specified OSS bucket and object. Therefore, in most cases, you do not need to manually call the AddMedia operation to process the media file.
Media information is automatically obtained only when the specified media workflow is in the Active state. If no media workflow is specified or the specified media workflow is not in the Active state, media information is not obtained.

QPS limit

You can call this operation up to 100 times per second per account. Requests that exceed this limit are dropped and you will experience service interruptions. We recommend that you take note of this limit when you call this operation. For more information, see QPS limit.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation
mts:AddMedia	create	All Resources *	none	none

You can search for all the media files that have the same tags in the Media Library. You can specify up to 16 tags for a media file. Separate multiple tags with commas (,). Each tag can be up to 32 bytes in size The value must be encoded in UTF-8.	tag1,tag2

InputUnbind	boolean	No	Specifies whether to check if the media workflow supports the specified input path. We recommend that you set this parameter to true to prevent errors that may result from invalid paths. Valid values: true: checks whether the workflow supports the specified input path. false: does not check whether the workflow supports the specified input path.	false
CateId	long	No	The ID of the category to which the media file belongs. The value cannot be negative.	123
OverrideParams	string	No	The subtitle settings that are used to overwrite the original settings. Example 1: Use `{"WebVTTSubtitleOverrides",[{"RefActivityName":"subtitleNode","WebVTTSubtitleURL":"http://test.oss-cn-hangzhou.aliyuncs.com/example1.vtt"}]}` to overwrite the original subtitle settings during HTTP Live Streaming (HLS) packaging. Example 2: Use `{"subtitleTransNodeName":{"InputConfig":{"Format":"stl","InputFile":{"URL":"http://subtitleBucket.oss-cn-hangzhou.aliyuncs.com/package/example/CENG.stl"}}}}` to overwrite the original subtitle settings during Dynamic Adaptive Streaming over HTTP (DASH) packaging.	{“subtitleTransNodeName”:{“InputConfig”:{“Format”:”stl”,”InputFile”:{“URL”:”http://exampleBucket.oss-cn-hangzhou.aliyuncs.com/package/example/CENG.stl"}}}}

Triggering and matching rule for a workflow

MPS checks whether the URL of the input file contains the URL to which the workflow is bound. If yes, the workflow matches the input file and runs. Otherwise, the workflow does not match the input file and does not run. Example: The URL of the input file is http://bucket.oss-cn-hangzhou.aliyuncs.com/A/B/C/test1.flv.

1. When a media file is added to http://bucket.oss-cn-hangzhou.aliyuncs.com/A/B/C/, the workflow is triggered.
2. When a media file is added to http://bucket.oss-cn-hangzhou.aliyuncs.com/A/B/, the workflow is triggered.
3.When a media file is added to http://bucket.oss-cn-hangzhou.aliyuncs.com/A/, the workflow is triggered.
4. When a media file is added to http://bucket.oss-cn-hangzhou.aliyuncs.com/, the workflow is triggered.
5. When test.flv is added to http://bucket.oss-cn-hangzhou.aliyuncs.com/A/B/C/, the workflow is triggered.
6. When a media file is added to http://bucket.oss-cn-hangzhou.aliyuncs.com/A/B/CC/, the workflow is not triggered.
7. When a media file is added to http://bucket.oss-cn-hangzhou.aliyuncs.com/A/B2/, the workflow is not triggered.
8. When a media file is added to http://bucket.oss-cn-hangzhou.aliyuncs.com/A2/B/C/, the workflow is not triggered.

NoteWhen you create a media workflow, do not configure the input URL of a workflow to be the same as the prefix of the input URL of another workflow. Otherwise, two workflow execution instances will be triggered for adding one media file. For example, if you specify the test folder for the first workflow triggering rule and the test1 folder for the second workflow triggering rule, the two workflows are triggered when a media file is added to the test1 folder.

File name extension matching

Only multimedia files can trigger workflows. MPS determines whether to trigger a workflow by checking the file name extensions. A workflow is matched for a file that does not have a file name extension or a file with the name extension described in the following table. A file that does not have a file name extension has no separator dot in the file name.

NoteFor SWF files, the snapshot and transcoding features may not deliver optimal performance.

Type	File name extension
Video	3gp, asf, avi, dat, dv, flv, f4v, gif, m2t, m3u8, m4v, mj2, mjpeg, mkv, mov, mp4, mpe, mpg, mpeg, mts, ogg, qt, rm, rmvb, swf, ts, vob, wmv, webm
Audio	aac, ac3, acm, amr, ape, caf, flac, m4a, mp3, ra, wav, wma, aiff

Media workflow message

Media workflows use Alibaba Cloud Message Service (MNS) to send messages to MPS service users. A media workflow sends a message when the Start or Report activity is complete. To receive the message, you must set the queue or notification name on the Start activity. The message generated by the media workflow is stored in the queue or notification. You can use MNS SDK to obtain the message. The following table describes the message specifications.

RunId	String	The ID of the workflow execution instance.
Name	String	The name of the activity.
Type	String	The type of the activity. Valid values: Report and Start.
