Considerations When Adding and Managing Channels

General Setup Considerations

Slates

Videos that play when the live stream fails or is not available. A Slate must be at least 30 seconds long.

Tip: Slates are required for each channel. Upload a slate before you start to add any channels. The type of slate you can use depends on your Live Account configuration.

Supported formats:

Video: .mov, .mp4

Add event to a schedule	Yes	Yes
Start an event	Yes	No

Encoding Setup

The Encoding Setup is available when the Packaging Partner is Ooyala Package. The following information includes considerations, tips, and general knowledge needed to understand and successfully configure encoding for your channel.

Encoder Location

The Encoder Location is a geographic location for an encoder. A default encoder location is set during the initial configuration of you Live account. Other available encoder locations are listed in the Encoder Location drop-down list. Encoding costs are based on geographic region.

Encoder Input Profile

Select whether to use one or two inputs where the secondary input provides fail-over content.

The default Elemental Input Profile option requires two inputs: Input 1 takes your primary content. Input 2 takes your non-ad fail-over content. When the Input 1 stream is interrupted during a live event, the video output stream displays fail-over content from Input 2.

Encoder Output Profile

The Packaging Partner selected in general setup determines encoding options. Only one encoding option is available at a time.

Packaging Partner	Encoding Option
Ooyala Package	elemental-live-delta
Ooyala Akamai	elemental-live-akamai
Custom	No encoding page is displayed.

Input 1

Type
Name
Streaming Protocol
- RTMP—option (Real-Time Messaging Protocol)
- RTP—option (Real-Time Transport Protocol)
Encoder Mode
- RTMP Push—indicator, the encoder pushes the content to input 1.
- RTMP Pull—indicator, the encoder relies on Input 1 to pull the input stream.
Input Name Visioning—this setting guarantees that using multiple encoders at different times for the same channel won't cause ingest breaking. The default is not enabled.

Input 2

These are slates or play-list that are shown when Input 1 fails.

Type—you can use a slate in either .mov or .mp4 format. If your account has play-lists enabled, you can specify a play-list for Input 2 fail-over.
Name—the name will always be "Input 2."
Input Path—is the full path for the location of the file or play-list.
Note: Set Enter manually to enter the fully qualified path to the file you want to use for your slate. The file must be located on the same server that is running your Live account.

Output 1

Type— the protocol for the output, such as HLS-WEBDAV (HTTP Live Streaming - Web Distributed Authoring and Versioning).
Stream Count—the number of content streams being output by the channel.

Packaging Setup

During the Create New Channel process, on the General Setup page, setting Packaging Partner to Ooyala Package, and clicking Next Step displays the Packaging Setup page.

Channel Type

Ad-hock runs for a finite period.
24x7runs continuously.

Packager Location: Ooyala sets up capabilities in the system for your provider account. Each geographic region has an associated cost in your account. The defaults are set up in the drop-down lists.
Packager Input Filter Template: Select one of the available templates.
Packager Output Filter Template: Select one of the available templates.
DVR Settings: Limited DVR automatically archives the channel for on-demand playback. No DVR disables this capability.
Input 1: Displays the packager input type (e.g., Type: webdav).
Output 1: Displays the packager output type (e.g., Type: hds, Name: hds_package).
Output 2: Displays the packager output type (e.g., Type: hls, Name: hls_package)

The following parameters are available when Packaging Partner is set to Ooyala Akamai:

Channel Type: Select the type of channel:
Ad-hoc runs for a finite period.

24/7 runs continuously.
Channel Account/Location: Ooyala sets up capabilities in the system for your provider account. Each geographic region has an associated cost in your account. The defaults are set up in the drop-down lists.
Config Name: Select one of the available names.
Input Formats: Displays the format of the current input (e.g., RTMP).
Output Formats: Displays the format of the current output (e.g., HLS,HDS).
Ingest Password: Enter the authentication password for pushing content to Akamai.
DVR Settings: Limited DVR automatically archives the channel for on-demand playback. No DVR disables this capability.
Primary Contact, Secondary Contact: Select the name of your primary and secondary contacts at Ooyala.
Primary Encoder, Secondary Encoder: Set to 200.29.181.5. This ensure that the edge server to Akamai will be closest as established via a least path algorithm.

The following parameters are available when Packaging Partner is set to Custom:

DASH—Dynamic Adaptive Streaming over HTTP (DASH)
HLS—Apple HTTP Live Streaming (HLS) URL.
HDS—Adobe HTTP Dynamic Streaming (HDS) URL.
Smooth—Microsoft Smooth Streaming URL.

Syndication Considerations

Supported Social Media

Enable or Modify Social Media Stream

The channel must be stopped in order to enable or modify social media streaming configuration.

Tip: You can enable a social media stream at the same time you add a channel.

Starting and Stopping Syndication

Once a social media stream is enabled and the channel is running, you can start or stop each social media stream.

Channel Maintenance Considerations:

Important: Clipping enabled channels must be restarted for the following encoder or service changes:
- Bitrate changes
- Caption changes
- Time clock modifications
- Starting or stopping ingest services

Restarting a channel clears any existing DVR buffer.
