Livestream Restreaming without Transcoding – AWS Elemental

0

Hi,

is it possible to restream the ingested livestream without transcoding to avoid quality loss?

The planned workflow is to ingest a SRT livestream with AWS Elemental MediaConnect and then restream the livestream with AWS Elemental MediaLive to YouTube and Facebook.

Is it possible to re-wrap the SRT stream into a RTMP stream without transcoding the video? I do it with FFmpeg all the time. How would I setup such a workflow in AWS Elemental?

Thank you.

Currently AWS Elemental MediaLive does not provide rewrapping to different protocols without transcoding. For MediaLive to create RTMP output streams, it needs to transcode from the input source. https://docs.aws.amazon.com/medialive/latest/ug/creating-rtmp-output-group.html

If your SRT stream contains a video with a bit rate higher than the desired RTMP distribution bit rate, then the transcoding of the video should not create much of a quality impact on the final output stream. This is a typical workflow that many providers use to create an RTMP source to social media feeds.

If you already have a working rewrap using FFMPEG, then you may need to create a component that receives the output transport stream from AWS Elemental MediaConnect. If the SRT stream to MediaConnect is a multiprogram stream (MPTS) then you will also need to select the desired stream within the MPTS to feed to the FFMPEG rewrapping.
