Note:

By default, the EBS volumes attached with the AMS instance are not marked for deletion. However, the data on the primary drive where the operating system and AMS are installed is not accessible. This is because the data cannot be mounted to a different instance. Adobe recommends that you copy the required content from the primary drive to a different EBS volume. You can mount this volume to a different AMS instance. In contrast, the data on the secondary drive can be mounted to any other instance.  

On-demand streaming

Multicast streaming

Flash Player 10.1, AIR 2

Note:

Adobe Media Server on Amazon Web Services supports peer-assisted multicast streaming. It does not support IP multicast or fusion multicast.

Copy the multicast tools to the webroot folder

Adobe Media Server includes a Multicast Configurator tool and a Multicast Player. To access these tools from a web browser, move them to the webroot directory on the instance.

  1. Connect to the instance. Follow the steps in Connect to an instance from a Windows computer or Connect to an instance from a Linux/UNIX computer.

  2. The following directory contains the multicast tools:

    /opt/adobe/ams/tools/multicast/

    Move the multicast directory to the following location:

    /mnt/webroot/

    Using WinSCP to move the /multicast directory to the /mnt/webroot directory

Configure a multicast event

To multicast a live stream, use the Multicast Configurator to configure the streaming event. The Multicast Configurator generates a Publisher Stream Name that you’ll use to publish a stream from Flash Media Live Encoder. The Multicast Configurator also generates an F4M (Flash Manifest) file that you’ll use to play the stream in the Multicast Player.

to generate a stream name and a manifest file for the Multicast Player

  1. Open the following URL in a web browser:

    http://public-dns/multicast/configurator/configurator.html

    For example:

    http://ec2-174-129-151-131.compute-1.amazonaws.com/multicast/configurator/configurator.html

  2. Select Peer to Peer multicast.

    Adobe Media Server on Amazon Web Services does not support Fusion or IP Multicast.

  3. Enter the server name (or IP address) and the full path to the multicast application:

    rtmfp://public-dns/multicast

  4. Enter the name of the live stream. This tutorial uses livestream.

  5. Enter a publish password.

    The password ensures that only the multicast server can publish a multicast stream into the group. Other peers do not have the publish password and can only play the stream, not publish a stream.

  6. Enter a name for the group. This tutorial uses the default name, ams.multicast.example.

    You can leave Make Unique unchecked.

  7. Click Generate. The Multicast Configurator generates the following:

    • A name for the live stream. To publish a stream, you’ll click Copy and paste this value into the Flash Media Live Encoder Stream field.

    • An F4M file to use with the client multicast player. To view the F4M file, click View Manifest File.

  8. Click Save Manifest File and do the following:

    1. Save the manifest.f4m file to your local computer.

    2. Connect to the instance. Follow the steps in Connect to an instance from a Windows computer or Connect to an instance from a Linux/UNIX computer.

    3. Copy the manifest.f4m file from your local computer to the following location:

      /mnt/webroot/multicast/multicastplayer/

      Using WinSCP to copy the manifest.f4m file to the instance

Publish a stream from Flash Media Live Encoder

  1. Launch Flash Media Live Encoder 3.1 or later and do the following:

  2. From the Preset menu, select a single stream preset. The multicast solution does not support multi-bitrate (also called “adaptive” and “dynamic”) streaming.

  3. For AMS URL, enter the URL of the multicast service:

    rtmp://public-dns/multicast

    Note:

    Flash Media Live Encoder connects to Adobe Media Server over the RTMP protocol, not over the RTMFP protocol.

  4. Return to the Multicast Configurator and click Copy next to the Publisher Stream Name.

  5. In Flash Media Live Encoder, paste the Publisher Stream Name into the Stream text box.

  6. Click Start to connect to the multicast service and start streaming.

    Use Flash Media Live Encoder to capture and encode a live stream

Play a multicast stream

  1. Open the following URL in a web browser:

    http://public-dns/multicast/multicastplayer/multicastplayer.html

    The Adobe Flash Player Settings manager displays a Peer Assisted Networking dialog. Click Allow to allow the peer-to-peer connection.

    Flash Player opens a Peer Assisted Networking dialog before the Multicast Player starts streaming

    The Multicast Player plays the stream that Flash Media Live Encoder is publishing.
