Live streaming is now available for, and one of the supported ingest protocols is RTMP. RTMP is a commonly used protocol for ingesting and delivering rich media including live streaming. Azure Media Services supports ingesting live feeds using RTMP and uses to dynamically transmuxe live streams for delivery in MPEG-DASH, Microsoft Smooth Streaming, Apple HLS, or Adobe HDS formats.

This enables using a widely adopted RTMP protocol for input and multiple output protocols to reach multiple devices and endpoints while maintaining compatibility with legacy players and formats.

This article focuses on RTMP ingest feature enabled by Azure Media Services, and how it can be used to source multi-bitrate live feed to Azure Media Services channels using Wirecast, Flash Media Live Encoder (FMLE) and FFmpeg encoders. Architecture and General Information At a high level, the Live Streaming architecture consists of three main components: Channel/Program, Storage and Streaming Endpoints. • Channel/Program- Channels enable live streaming. They include the ingest point for your live encoder. As of today RTMP and Fragmented MP4 (Smooth Streaming) are the supported ingest protocols.
A program is the logical component inside a channel. Program publish the received data for streaming and also archive the content for on-demand transformation and live presentation window (DVR).
• Streaming Endpoint and Streaming Units- a Streaming Endpoint provides you with a URL from which you can pull your live and VOD assets. Streaming Endpoints also provide dynamic packaging capabilities and secure the delivery of the streams. • Storage- Programs use Azure storage for storing live archives. On-demand streaming and encoding services also use storage.
Channel RTMP support Azure Media Services Channel supports RTMP push model. It can support both single and multi-bitrate inputs, but it is highly recommended to use multi-bitrate input to get the benefits of Adaptive Bitrate Streaming.
In future Azure Media Services will provide a live transcoder service which will convert single bitrate input to multi bitrate output. To use RTMP ingest, following is required: • RTMP output supported encoder • H.264 video and AAC audio codec output • Key frame or GOP (Group of pictures) alignment across video qualities • 2 second key frame interval (You can use up to 6 seconds, but this requires special configuration. Please see advanced settings section below) • Unique stream names for each quality • Network connectivity (Available bandwidth for aggregated video+audio bitrates) • Strict CBR encoding recommended for optimum Adaptive bitrate performance. In this post I will use three video qualities for output and ingest to Azure Media Services channel. You can use multiple qualities, but keep in mind that, the initial quality will be limited by your machine’s encoding capabilities and your network connection to the channel ingest.
If you exceeded your bandwidth or there is a poor network connection, you might need to adjust the quality count and also the encoding settings to use a lower resolution and bitrate. When using multiple qualities you should pay attention to the aggregated bitrate of all qualities. Note: Make sure to Reset your channel every time you change encoder settings and disconnect and reconnect your encoder to the channel. Wirecast Configuration Wirecast is a well-known RTMP encoder.

Wirecast version 5 and 6 is supported and tested with Azure Media Services. Below steps applies to both Wirecast version 5 and 6.
