AWS Elemental MediaLive Documentation

AWS Elemental MediaLive is a video processing service that enables video providers to encode live video streams for delivery to broadcast televisions and multiscreen devices. Used as a standalone service or integrated with other AWS Media Services, AWS Elemental MediaLive lets you control encoding parameters as you build 24x7 live video workflows or create event-based live streams. 

Video Standards Support

AWS Elemental MediaLive supports various video standards used to input, output, and archive live video. 

Broadcast Capabilities for Live Video Streams

AWS Elemental MediaLive supports broadcast features like ad markers, closed captions, and multiple language audio tracks. MediaLive also works natively with AWS Elemental MediaConnect, providing  transport of video to use as inputs to live channels.

Statistical Multiplexing (Statmux)

Statistical Multiplexing (Statmux) is a feature of the AWS Elemental MediaLive video processing service that lets you prepare and share live broadcast video for distribution. Statmux is a technology that allocates bits in real time among multiple live video channels, combining the encoded outputs into a single transport stream.  

Resource Provisioning

AWS Elemental MediaLive helps you manage the encoding resources needed to deliver live video streams. It deploys encoding resources and helps manage scaling, healing, resiliency failover, monitoring, and reporting.  

High Availability

Each live video channel you create with AWS Elemental MediaLive runs on redundant infrastructure. The service helps you monitor encoding resources for health and replaces any degraded components. You can configure resources to scale with demand.

Flexible Workflows

AWS Elemental MediaLive lets you build flexible 24x7 linear workflows or event-based live streams. The service helps you to output a mix of live video streams at different resolutions and bitrates to meet the requirements of the devices in the hands of your viewers.

Use Independently or with other AWS Media Services

As one of the AWS Media Services, you can choose to use AWS Elemental MediaLive as a standalone service or integrate it with AWS services for video transport, video-on-demand (VOD) processing, just-in-time packaging, ad personalization and monetization, or media-optimized storage. A typical integration would be to tie AWS Elemental MediaLive to our video transport, packaging and server-side ad insertion services for the core video workflow. Additionally, AWS Elemental Media Services are interoperable with other AWS services, such as the Amazon CloudFront CDN.
