To start live streaming on Microsoft Stream, you need an encoder. An encoder captures audio and video from various sources such as camera, microphone, desktop screen capture etc., and sends it to Microsoft Stream for live streaming to all your audience.

List of encoders tested by Microsoft

The following encoders have been tested by Microsoft for live streaming with Microsoft Stream. A subset of these encoders have been integrated into the product for ease of use and quick setup.

Do you have an encoder that is not in the above list? Not a problem! You can still use the encoder to stream to Microsoft Stream. Read the manual configuration of encoders to learn more.

Encoder setup in Microsoft Stream

When you save the Live event (read Creating live events for details), you can see the list of integrated encoders in the Select encoder drop down list on the Encoder setup tab.

Configure manually

Note: If you have an encoder that is not directly integrated into Microsoft Stream, see how to manually configure encoders to learn more about how to configure and setup your encoder for Live Streaming with Microsoft Stream.

Haivision KB Encoder and Makito X Encoder

If you have an existing Haivision KB or Makito X encoder, you can choose the appropriate option from the drop down list and follow the list of instructions.

Select Start setup to create a channel for Live Streaming. Wait for the setup to be complete. You will see a Ready to connect message on the screen.
After that's complete, download the preset that contains all of the encoding parameters including the ingest URL and event name. Import the preset into the encoder and start the encoder.
Go back to Microsoft Stream. After you are able to see the preview from the encoder, select Start event to go live so your audience can see the live event.

Note: Haivision KB Encoder support for RTMPS has not been tested yet. Haivision Makito X Encoder does not support RTMPS. The downloaded presets for both encoders contain the RTMP ingest URL.

When this is complete, you can go to your Switcher Studio app on your iPhone or iPad, select Microsoft Stream in the Output tab and start streaming to Microsoft Stream.
Go back to Microsoft Stream. After you are able to see the preview from the encoder, select Start event to go live so your audience can see the live event.

Note: Switcher Studio uses the RTMP ingest URL.

Wirecast

If you are an existing user of Wirecast, you can choose this option from the drop down list to send a live stream to Microsoft Stream. Note that you will need Wirecast version 10 or later.

Select Start setup to create a channel for Live Streaming. Wait for the setup to be complete. You will see a Ready to connect message on the screen.
Launch encoder will launch the Wirecast app on your machine pre-configured with the correct encoding parameters and ingest URL for that Live event. When ready click the Stream icon in the Wirecast app to start streaming to Microsoft Stream.
Go back to Microsoft Stream. After you are able to see the preview from the encoder, select Start event to go live so your audience can see the live event.

Note: The Wirecast app is launched with the RTMPS ingest URL pre-configured.

Prerequisites

Ensure there is a Streaming Endpoint running. For more information, see Manage Streaming Endpoints in a Media Services Account
Install the latest version of the AMSE tool.
Launch the tool and connect to your AMS account.

Tips

Whenever possible, use a hardwired internet connection.
A good rule of thumb when determining bandwidth requirements is to double the streaming bitrates. While this is not a mandatory requirement, it helps mitigate the impact of network congestion.
When using software-based encoders, close out any unnecessary programs.

Create a channel

In the AMSE tool, navigate to the Live tab, and right-click within the channel area. Select Create channel… from the menu.
Specify a channel name, the description field is optional. Under Channel Settings, select Standard for the Live Encoding option, with the Input Protocol set to RTMP. You can leave all other settings as is.
Make sure the Start the new channel now is selected.
Click Create Channel.

Note

The channel can take as long as 20 minutes to start.

While the channel is starting, you can configure the encoder.

Important

Billing starts as soon as Channel goes into a ready state. For more information, see Channel's states.
