Ingesting with MRSS

You can use Media RSS (MRSS) to have Ooyala pull your content from your own system from an MRSS feed that you publish. Backlot pulls the metadata from the MRSS feed and either creates a remote asset or downloads (from where they are hosted) and processes the videos and any associated files (thumbnails, closed caption files, etc.).

Note: This topic applies to both OIS v2.5 and OIS v1. Certain sections, where indicated, apply to just one version.

Overview of MRSS Ingest

About MRSS

Media RSS (MRSS) is an extension of RSS that allows you to syndicate multimedia files in RSS feeds. For technical details, see the Media RSS Specification.

Setting Up MRSS

Contact your Ooyala representative and indicate that you want to use MRSS. For each video you want to ingest, you must provide Ooyala with valid content URLs. URLs can include http:// or https://.

Using MRSS

To use MRSS, you upload metadata and/or videos and other files (thumbnails, closed captions) to a web server and create an XML manifest file that references the content.

Using MRSS to Upload Metadata Only

  1. Create an XML manifest file as described in XML Manifest File. You must use the ooyala:remoteasset tag for metadata-only ingestion.
  2. Upload the XML manifest file to one of the MRSS locations you provided. Make sure the filename and path matches exactly one of the paths you provided to Ooyala.

Using MRSS to Upload Videos, Thumbnails, and Closed Caption Files

  1. Upload one or more files (videos, thumbnails, and closed caption files) to a web server.
  2. Create an XML manifest file (see XML Manifest File). Make sure that the entries in the file reference the files on your server. In particular, the value of the <media:content> element's href attribute must be an HTTP URL to the file on your server, as in the following example:
    <media:content url="" />
  3. Upload the XML manifest file to one of the MRSS locations you provided. Make sure the filename and path exactly matches one of the paths you provided to Ooyala.
    Note: Unfortunately, the concept of "client logging" does not apply to MRSS feed-based processing. The best way to verify that your feed is processing successfully is to check for the appearance of your assets, either with the Backlot UI or the Backlot API /v2/assets request.
After the videos and any other associated files are processed, to upload more files, you simply upload another MRSS file in the agreed-upon location.

Validating MRSS Feeds (OIS v1)

You can use one of the following feed validators to validate the MRSS feeds you create:

Validating MRSS Feeds (OIS v2.5)

You can use the following DTD to validate MRSS feeds you create: Ooyala MRSS Feed Validator

Validating Closed Captions

Use the Ooyala Closed Captions Validator to check your DFXP/TTML documents for your convenience.
Note: We provide Ooyala-specific DFXP support. Even if you follow the w3c document definition for DFXP/TTML, it may not be supported. If you run into any issues with your DFXP/TTML files, contact your Ooyala support representative.
