Hosted Slicers (Legacy)

ℹ️

Uplynk’s Hosted Slicers solution has reached its end of life, and will be shut down on June 30th, 2025. Hosted Slicers has been replaced with a completely rewritten Cloud Slicers solution. Cloud Slicers are easier to use, more stable and have a richer feature set. Start using Cloud Slicers today.

Hosted Slicers allows you to run a slicer in our cloud. This allows you to ingest and encode content without on-premise hardware. You may customize this slicer in the following ways:

• Choose an ingest point that defines where it will be hosted and the streaming protocol for the audio / video feed that will be ingested.
• Select the version of the slicer software that it will run.
• Define a slicer configuration that determines how the audio / video feed will be ingested and processed.

Create and delete slicers as required by your business needs.

Quick Start

Set up a streaming workflow by performing the following steps:

1. Create an Ingest Point in the region where your Hosted Slicer will be hosted.

   The purpose of an ingest point is to persist your ingest URLs even when switching to a different Hosted Slicer. This means you will not have to update your encoder's publishing configuration when switching to a different Hosted Slicer.

2. Create a Hosted Slicer in the same region as the above ingest point.

3. Add Hosted Slicer to the desired live channel, live event, or failover group.

4. Push Video Feed from your encoder to the ingest point created in step 1.

5. Point Your Player to your live channel or live event's playback URL.

Ingest Point Administration

An ingest point identifies a URL and ports to which an encoder should push an audio/video feed.

Upon creating a Hosted Slicer, you must associate it with an ingest point from which it will ingest an audio/video feed.

Key Information

• An ingest point is restricted to a specific region and streaming protocol.
• An ingest point can be in either of the following states:
  • IN_USE: This state indicates that it has been associated with a Hosted Slicer.
  • NOT_IN_USE: This state indicates that it is available for assignment to a Hosted Slicer.
• Deleting a Hosted Slicer changes the state of the ingest point that was associated with it from IN_USE to NOT_IN_USE. This allows you to reuse the same ingest point with a different Hosted Slicer.

Create an Ingest Point

1. Navigate to Ingest Points: From the main navigation, go to Slicers > Ingest Points.
2. Click + Ingest Point.
3. In the Endpoint Name option, assign a name to the ingest point.
4. In the Type option, select the streaming protocol for the feed that will be ingested.
5. In the Region option, select the region where the Hosted Slicer that will ingest this feed will be hosted.
6. Optional: In the Endpoint Description option, type a description for this ingest point.
7. Click Create.

Modify an Ingest Point

You may not reassign an ingest point to a different region. Create a new ingest point if you require one for a different region.

1. Navigate to Ingest Points: From the main navigation, go to Slicers > Ingest Points.
2. Click on the desired ingest point.
3. In the Name option, modify the name assigned to this ingest point.
4. Optional: In the Description option, modify the description assigned to this ingest point.
5. Click Save.

Delete an Ingest Point

1. Navigate to Ingest Points: From the main navigation, go to Slicers > Ingest Points.
2. Check the ingest point's status:
   • IN_USE: You cannot delete an ingest point that is in this state. You must first delete the Hosted Slicer associated with it.
   • NOT_IN_USE: Proceed to the next step.
3. Click on the desired ingest point.
4. Click Delete Ingest Point.
5. Click Yes > Delete to confirm the deletion.

Cloud Slicer Live Administration

Before creating a Hosted Slicer, you must first perform the following steps:

1. Identify the Region (e.g., Oregon or Ohio) where your Hosted Slicer will be created.

2. Identify the Streaming Protocol through which your feed will be published to a Hosted Slicer. A Hosted Slicer supports the following protocols: RTP | RTMP | SRT | RIST

The SRT streaming protocol requires slicer version 22060200 or higher.

3. Create an Ingest Point point within the region identified in step 1.

Key Information

• You may assign a custom slicer configuration to your Hosted Slicer. You can define this custom configuration by:

  • Importing settings from a file
  • Manually adding settings
  • A combination of both

• You may import settings from a file. We support the following formats:

  • Text File: Import a file that uses the same format as a Live Slicer configuration file. Specify each desired setting on a separate line.

  • JSON: Import a file containing settings defined as key-value pairs using JSON notation.

    Learn more.

• Our service manages certain slicer configuration settings. You should not manually assign these reserved settings to your Hosted Slicer.

Create a Hosted Slicer

1. Navigate to Hosted Slicers: Go to Slicers > Hosted Slicers from the left navigation of the main page.

Slicer Status Information

Use a Hosted Slicer's status to find out whether it is ready to stream your content. Core Hosted Slicer statuses are described below:

• pending: Indicates that our service has not started provisioning your Hosted Slicer.
• initializing: Indicates that our service is in the process of creating your Hosted Slicer.
• created: Indicates that your Hosted Slicer has been created, but is not in use.
• running: Indicates that your Hosted Slicer is active. An active Hosted Slicer can be in any of the following states: capture, replace, ad, or blackout.
• failed: Indicates that our service could not create your Hosted Slicer.

Reserved Slicer Configuration Settings

You may not use the following settings with a Hosted Slicer:

api_port | apikey | capture_delay | multicast | no_signal_image | no_signal_pad | port | rtmp_url | rtp_backlog_dur | rtp_headers | rtp_readahead_dur | ssl_port | username

Slicer Configuration File

You may import a slicer configuration file when defining your Hosted Slicer's slicer configuration. You may format this slicer configuration file using either colon-separated values or JSON.

You may not define a reserved slicer configuration setting within a slicer configuration file. Attempting to import a file that contains a reserved setting will generate an error.

Our service automatically detects the format when importing your slicer configuration file. It does not rely on the file extension when making this assessment.

Colon-Separated Values (Live Slicer Configuration File)

You may define slicer configuration settings using the same format as a Live Slicer configuration file. Specify each desired setting on a separate line.

Syntax: "{Setting}": "{Value}"

Example:

remote:on
description:Sports
input:rtmp
autoexpire_age:3
slicerID:sports_slicer

JSON

You may define slicer configuration settings using JSON format. Define each slicer configuration setting as a key-value pair using JSON notation.

Syntax: "{Setting}": "{Value}"

Example:

{
	"remote": "on",
	"description": "Sports",
	"input": "rtmp",
	"autoexpire_age": "3",
	"slicerID": "sports_slicer"
}

Encoder

Your encoder must push an audio/video feed to an ingest point. If you have assigned that ingest point to a Hosted Slicer, then that Hosted Slicer will automatically encode your content.

Our service will only ingest your feed when the following conditions are met:

1. Encoder Configuration: Your encoder is configured to push an audio/video feed to the Hosted Slicer's streaming URL.

   Sample publishing URL:

   rtmp://ingest-prod-1-us-east-1.mss.aws.oath.cloud/slicer12345

2. RTP, SRT, and RIST: Your encoder's IP address matches the one defined in the ingest point's Source IP Address option.

   You may bypass this restriction and allow your feed to be pushed from any IP address when this option is set to 0.0.0.0.

3. SRT Only: You must configure your encoder to pass the Hosted Slicer's streaming key along with your feed. This configuration varies by encoder. If your encoder does not provide a password option when defining an SRT publishing target, then you should include the passphrase query string parameter in the publishing URL.

   Syntax: ?passphrase=Streaming Key

   You can find this streaming key by viewing the desired Hosted Slicer's Streaming Information section.

   Sample publishing URL:

   srt://ingest-prod-1-us-east-1.mss.aws.oath.cloud:48120?passphrase=7b4777ca-c0de-410b-913e-a011607ef525

Link Health Monitoring

A link is established when an encoder starts pushing an audio/video feed to an ingest point. Hosted Slicer performance relies on this link, and therefore, we track key link health metrics. These metrics are measured by:

• Session: Provides link health, aggregated in some cases, from the moment the link was established. Use session statistics to assess the overall health of the link between the encoder and the Hosted Slicer.

• Recent Interval: Provides the most recent link health measurement. Use these statistics to identify recent trends (e.g., link health improvements or degradation).

View these metrics from within the Link Monitor section of the desired Hosted Slicer.

Link health metrics are described below.

Dashboard

The Live Slicer Monitoring dashboard provides statistics and graphs that describe Live Slicer health.

The left pane

• Determines whether you will view the Slicer View(s) associated with your personal user account or your organization's shared ones.
• Allows you to switch to a different Slicer View.
• Indicates the current Slicer View and the number of Live Slicers associated with it by health status.
• Toggles Live Slicers from the dashboard by owner. For each owner, it also indicates the number of Live Slicers by health status.

The right pane provides the following information and statistics for each Live Slicer associated with the current Slicer View.

Key Information

By default, all Live Slicers that have been associated with the currently selected Slicer View and that have been active within the last 24 hours are displayed on the dashboard. This list may be filtered by Live Slicer ID, health status, or account owner.
