Audio Late binding Support (2019-05-15)
Ooyala OTS now supports the association of additional audio track for the content already ingested and processed. The new audio track can be used to provide an additional language, a new audio service type, etc.
Ingestion is supported through manifest-based ingestion to the Ooyala Ingestion service only. Here is a sample manifest:
<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0" xmlns:media="http://search.yahoo.com/mrss/" xmlns:dcterms="http://purl.org/dc/terms/" xmlns:fh="http://purl.org/syndication/history/1.0" xmlns:ooyala="http://www.ooyala.com/mrss/">
<media:content url="test.aac" ></media:content>
<media:thumbnail url="my_thumbnail.jpg" filesize="35712"></media:thumbnail>
<media:description>This is an example</media:description> <ooyala:labels>/test,/example,/xml</ooyala:labels>
<ooyala:embedcode>Embedcode of the Asset</ooyala:embedcode>
<ooyala:metadata name="default_language">eng</ooyala:metadata> <dcterms:valid>start=2011-10-02-25T15:15:00-07:00; end=2026-12-25T16:00:00-07:00</dcterms:valid> <ooyala:profileguid>57d5a5a10f654fe79ef954dc8d29a108</ooyala:profileguid>
ooyala:audiolatebinding is required and must be
ooyala:replace is optional, but if it is present, it must be set to
true, or the ingest will fail.
- The duration of the audio file should match the duration of the video - if it does not, playback issues may occur.
- When audio description audio tracks are supplied for late binding, then specific profile with channel layout to be used and supplied as
part of the manifest.
- The following formats are supported for late binding: m4a, mp3, wma, aac, wav, and ogg
- If the audio Codec is not compatible with "mp4" container, the audio stream will be encoded for AAC/LC/Stereo during the late binding process.
- Additional billing will apply for processing of content replacement for all streams specified in the profile.
- All the limitations for multilingual and audio description processing apply for this incremental promotion of the content through late binding.
- Late binding audio streams will be appended to the existing source.
- Audio Late binding is not supported for Azure In region customers.
- Initial source default language will be preserved even when late binding source have default audio tracks.
- Audio Latebinding is not supported for Audio-only or Video-only assets.
- Currently, the Audio asset is not stored in the S3 bucket. Only the merged file is stored in the S3 bucket.
- Audio Late binding feature is applicable only for mp4 assets.
Support for VR 360 Uploads via OIS (2017-12-20)
release introduces support for uploading VR 360 videos into Backlot using OIS. Uploading a VR
360 video is similar to ingesting a flat video, with the addition of metadata that is unique
to VR 360 - label the file as VR 360 and specify the VR 360 type (monoscopic or stereoscopic).
For an overview, see VR 360 Videos
Dashboard Enhancements and In-Region Ingestion (2017-10-12)
- Performance enhancements increase the average speed of content being
ingested. Content is more quickly available for playback.
- In-region ingestion and transcoding
using Azure Media services, reducing overall ingestion and transcoding time
and keeping content in the same region as the customer.
See About Ingesting Content.
- New search feature in Ingestion Dashboard. Look up an asset that is being
ingested and view its status.
- More information visible to more user roles in Ingestion Dashboard. It is
no longer required to log in with Upload Only privileges to see the Ingestion
Dashboard (Ingestion Feed Activity tab). All user roles can now see this
dashboard. The amount of information that can be seen is determined by the
credentials used to log in to Backlot, as shown in the following table:
||View the status of ingest jobs you initiated.
|All other user roles

New Language and Framerate Options for Closed Caption
If you use manifest files to ingest closed caption
files via the Ooyala Ingestion Service (OIS), you can now optionally specify the
language and framerate of the closed caption file. See Ingesting Closed Caption Files
New Ingestion Dashboard (2017-05-10)
The Backlot UI
added an Ingestion Feed Activity
tab that displays a read-only
log of files submitted for ingestion to Backlot via the Ooyala Ingestion Service (OIS).
This dashboard displays the name and type of the submitted file, its processing status,
and other related information. You can filter the view to narrow search results. To see
this tab, you must log into Backlot as a user with upload only
details, see Viewing the Ingest Log in Backlot
XML Manifest Validation in OIS v2.5 (2017-03-06)
OIS 2.5 users, the system has been enhanced to allow unsupported elements and tags in
XML manifest files. As long as the required Ooyala elements and tags (ooyala.dtd) are
present, the system logs allows the ingestion process to continue without the process
failing. Previously, unsupported tags in a manifest would cause an ingestion failure.
