Channel API

APIs for channels let you Create, List, Fetch and Delete Channels.

Creating a Channel

This API allows to create a channel.

Creating a Channel Request

Send a PUT request to the /pcast/channel endpoint as shown:

PUT /pcast/channel HTTP/1.1
Host: pcast.phenixrts.com
Accept: application/json
Authorization: Basic YXBwbGljYXRpb25JZDpzZWNyZXQ=
Content-Type: application/json
Content-Length: 172
 
{
    "channel": {
        "alias": "<channelAlias>",
        "name": "<channelName>",
        "description": "<channelDescription>",
        "options": [<channelOptions>]
    }
}

The Content-Length header is automatically populated by curl. If using another method to access the API, you must calculate and populate the Content-Length header.

Request Headers

Header	Description
Authorization (required)	Use HTTP Basic Authentication with your applicationId and secret

Request Fields

Field	Description
channel (required)	Channel Object

Channel Object

Field	Description
alias (required)	A user friendly unique identifier for the channel. An empty string is required if you want the Streaming platform to generate an alias for your channel.
name (required)	Unique name of the channel.
description (required)	A description for the channel.
options (required)	An array of options for the channel. An empty array is required if there are no options.
ingestOptions (optional)	An object that defines default values for ingest parameters.

Channel Object Ingest Options

ingestOptions Usage

The capabilities defined by ingestOptions are only applied when publishing via RTMP. When publishing to the Channel using any method other than RTMP (e.g., SRT or the Phenix Web SDK), the capabilities and tags set using this method are not applied.

Field	Description
capabilities (optional)	An array of capabilities.
tags (optional)	An array of tags applied to the published stream.
screenName (optional)	The screen name of the channel member representing this ingest. The screen name is automatically chosen to properly enable functionality such as HA publishing.
maxFps (optional)	[Advanced] Controls the maximal frame rate sampled from the source signal when using `source-uri-ingest`. Support of signals with more than 30 FPS is experimental.
buffer (optional)	[Advanced] The amount of buffer to use on the ingest side to compensate for network jitter when using `source-uri-ingest`.
prerollSkipDuration (optional)	[Experimental] Milliseconds to skip at the beginning of the stream when using `source-uri-ingest`.
jitterBuffer (optional)	[Experimental] The amount of jitter buffer to use after decoding and sampling of the ingest signal. This value should generally equal to or larger than the value of `buffer`.

Creating a Channel Response

The platform will return a successful response that contains a "status" field. The HTTP status code is set according to the "status" field.

Fork a Channel

This API allows the caller to copy the active members (that is, the publishers) from one channel to another channel. Both the source and destination channels must have previously been created.

A stream will be associated with the destination channel which is a fork of the stream being published to the source channel with the same content.

Fork a Channel Request

Send a PUT request to the /pcast/channel/<urlEncodedDestinationChannelId>/fork/<urlEncodedSourceChannelId> endpoint as shown:

PUT /pcast/channel/<urlEncodedDestinationChannelId>/fork/<urlEncodedSourceChannelId> HTTP/1.1
Host: pcast.phenixrts.com
Accept: application/json
Content-Type: application/json
Content-Length: 86
Authorization: Basic YmlsbHk6c2VjcmV0cGFzc3dvcmQ=
 
{
    "streamCapabilities": [],
    "streamTags": ["my-channel-fork"],
    "options": []
}

Encoding

Channel ID may contain characters that are unsafe for URLs. Be sure to encode the ChannelId in the URL path. For example, the URL encoding of us-central#us-central is us-central%23us-central.

The Content-length header is automatically populated by curl. If using another method to access the API, you must calculate and populate the Content-length header.

Request URI

Component	Description
urlEncodedSourceChannelId (required)	URL encoded Channel ID of the source channel to fork from.
urlEncodedDestinationChannelId (required)	URL encoded Channel ID of the destination channel to fork into.

Request Headers

Header	Description
Authorization (required)	Use HTTP Basic Authentication with your applicationId and secret

Request Fields

Field	Description
streamTags (optional)	An array of tags (strings) to apply to the destination streams.
streamCapabilities (optional)	An array of capabilities (strings) to apply to the newly forked stream.
options (optional)	An array of options (strings) for the channel. Current valid options are: "force", "additive" and "keep-streams". The default behavior is not touch the stream(s) with matching session IDs that are already publishing to the destination channel. With the "force" option, the stream(s) will be terminated and replaced. With the "additive" option, the stream(s) will be added to any existing members in the channel. "keep-streams" removes the members but leaves the streams alive. Clients will receive the member update, but they are not securely terminated from the stream. In Phenix client implementations the default is to end the client stream, but customer client implementations may vary.

Fork a Channel Response

The API call returns an HTTP response per the following:

Channel ID may contain characters that are unsafe for URLs. Be sure to encode the ChannelId in the URL path. For example, the URL encoding of us-central#us-central is us-central%23us-central.

The Content-Length header is automatically populated by curl. If using another method to access the API, you must calculate and populate the Content-Length header.

Request URI

Component	Description
urlEncodedChannelId (required)	URL encoded ID of the channel
manifest (required)	The manifest ID such as live.m3u8 for HLS and live.mpd for DASH.

Request URI Parameters

Parameter	Description
streamToken (optional)	Streams protected with `token-auth` require a valid edge auth token to be provided.
