Proxies

Setting Up a Proxy

A proxy enables you to play your media assets and view your image assets in both the Core / MAM / Reviewer UIs. You can adjust your existing import workflow so that it automatically creates proxies for both image and media assets.

When you upload, the proxy it is treated as a child of that asset. This is shown below in the Core UI:

There are two methods in which to set up a proxy for your image assets.

1) You can create an import workflow with a seperate inbox just for images assets.

2) You can update your current media asset import workflow, so that it ingests and creates proxies for both media assets and image assets.

Method 1: Creating an Import Workflow with an Inbox for Image Assets

To create an import workflow with an inbox specifically for images assets, consult the A Basic Import Workflow guide. This includes creating a proxy for your images assets.

Method 2: Updating Your Current Import Workflow

To set up a proxy for an image asset, you will need to do the following:

1) Create and configure a transcode resource

2) Create and configure a transcode profile

3) Create a proxy action

4) Create a decision action so that your workflow can create proxies for both media and image assets in the same workflow.

5) Adjust your existing import workflow so that it contains the create image proxy, and decision node.

1) Create a Transcode Resource

To create a transcode resource, follow these steps:

1) On the toolbar, click the New option.

If you are creating an image proxy, you must select Image Transcode, otherwise the transcode will not work.

8) Click Save.

9) Click Enable.

3) Create a Proxy Action

14) Click Save.

15) Click Enable.

Updating Your Import Workflow

If you have an existing media asset import workflow set up, you will need to adjust it, so that it creates a proxy for both image assets and media assets. You can do this by creating a groovy scripted decision action. The groovy scripted decision action uses a script that can determine whether the asset you have imported is either an image asset or a media asset and then create a proxy.

Creating a Groovy Scripted Decison Action

To create a groovy scripted decision action, follow these steps:

1) In the Ooyala Flex console, on the toolbar, click New.

2) From the drop down, select Action.

3) Give your action a name and optional description.

4) In the Visibility field, select which accounts, workspaces, and groups in which you want the action to appear.

5) In the Plugin Type field, select Decision.

6) In the Plugin field, select Groovy Scripted Decision Action.

7) Click Save.

8) Click the Configuration tab.

9) Click Edit.

10) Expand the Script field, by clicking the + symbol.

11) In the text box, enter the following script:

def execute(){ Long resourceId = context.getMioObjectVariable("resource").id String name = context.getStringVariable("resourceItemName") ResourceService resourceService = services.getResourceService() if (resourceService.capacityItemSupportsImageType(resourceId,name)){ return true } return false }

12) Click Save.

13) Click Enable.

14) Navigate to your existing workflow.

14) Update your existing import workflow, so that it contains:

  • A decision action
  • An additional import node so that images can be imported
  • A create image proxy.

The workflow will look like this:

Recommended Proxy details

If the proxy is stored in S3 make sure the cors headers, create a cors configuration from the AWS console:

  
			resource "aws_s3_bucket" "Name" {
			bucket = "Bucket_Name"
			acl    = "private"

			cors_rule {
			allowed_headers = ["Authorization"]
			allowed_methods = ["GET"]
			allowed_origins = ["*"]
			//expose_headers = ["ETag"]
			max_age_seconds = 3000
			}
		   }
