AWS Elemental MediaConvert enabled with MP3 Audio Output

AWS Elemental MediaConvert can now create MP3 audio files and has introduced a new feature of expanded support for audio-only workflows. It is a file-based video transcoding service offering broadcast-grade features and allows the users to create video-on-demand (VOD) content multiscreen delivery and broadcast. It will change the conventional ways of producing MP3 audio used across various media. MediaConvert offers MP3 creation in several forms such as standalone audio conversion jobs, extracted from video files, or as supplementary outputs obtained in the process of video transcoding. It is a perfect amalgamation of simple web services interface with advanced video and audio capabilities and pay-as-you-go pricing. AWS Elemental MediaConvert simplifies the process of building and operating your own video processing infrastructure allowing you to focus on delivering captivating media experiences to your audience. This feature will prove to be very beneficial for all audio and video providers across the globe in transcoding on-demand content for their users with full reliability. Users can either opt for its independent functionality or they can harness MediaConvert functions as a part of AWS Media Services.

How To Set-Up Video on Demand[VOD] Using AWS MediaConvert

In case when working with broadcasting videos for a web application or for broadcast cable, you will need to deliver the video in some standard format that provides a high quality and consistent experience to viewers or end-users. MediaConvert provides the mechanism for converting videos to formats accordingly.

AWS Elemental MediaConvert supports set of input formats and adaptive bitrate (ABR) packaging output formats for delivering high-quality content from a range of sources onto primary and multiscreen devices.

Find below following components of AWS MediaConvert :

1. Jobs : Job is nothing but does transcoding task. Every job convert input file to the intended output file.
2. Queues : Queues are used for parallel processing of jobs.
3. Presets : Presets are group of encoding settings for a single output.

Now we will see workflow for creating MediaConvert Job with taking input as .mp4 file from S3 bucket and creating an output in Apple HLS format with multiple presets.

Now we will see use-case where we will be setting up simple serverless video on demand (VOD) workflow so we can experiment with streaming video with AWS MediaConvert. In this setup we will first setup an Amazon S3 bucket with associated Lambda trigger that submits a transcoding job using Amazon Elemental MediaConvert when a new file is uploaded/ingested in S3 bucket. The transcoding job specifies video packaging settings like HLS and DASH format along with the bitrates that are intended from the transcoded output. This information is all stored in another Amazon S3 bucket. Finally, the videos are streamed securely by Amazon CloudFront, restricting access to the Amazon S3 bucket by using origin access identity (OAI).

Following is the architecture of above discussed scenario.



Thus with the above workflow we can proceed and setup an seamless VOD using AWS MediaConvert Service.
