For AWS Elemental Live’s documented ultra-low-latency DASH output, create a DASH output group and enable both Chunked Encoding and Chunked Transfer. First confirm that the receiving HTTP server or AWS Elemental MediaStore destination accepts chunked DASH. These settings let Elemental Live send fragments before a complete segment is finished; they do not guarantee a particular end-to-end latency.
Check that the delivery path supports chunked DASH
AWS documents this procedure for sending DASH output to an HTTP server or AWS Elemental MediaStore. Before configuring the event, ask the destination operator whether the receiver accepts DASH chunked encoding and chunked transfer. AWS says the feature works with downstream systems that can accept DASH, but recommends discussing requirements with the downstream administrator.

This check matters because Elemental Live can send fragments sooner, but the receiving system must be able to handle them. A destination that expects a completed segment may not benefit from the setting.
Configure the Elemental Live DASH output
- Start with the normal event and DASH output-group workflow. Configure the Elemental Live event and create a DASH output group for the intended destination.
- Enable Chunked Encoding. This allows Elemental Live to deliver fragments before a full segment is complete.
- Review Fragment Length and Segment Length. Adjust these values if the downstream workflow requires it. AWS does not prescribe universal values on its setup page; settle them with the destination administrator and consult the interface help.
- Select the HTTP Push Dialect. The Chunked Transfer field appears after the appropriate dialect is selected.
- Enable Chunked Transfer. Confirm that both Chunked Encoding and Chunked Transfer are enabled for the DASH output.
- Test the full delivery and playback chain. Validate output at the real receiver and player, then measure latency in that deployment.
What determines the actual latency
Chunked DASH changes how Elemental Live sends media fragments; it is not a complete end-to-end latency setting. The receiver, packaging and delivery chain, player, network, and their configurations all affect when a viewer sees the content. AWS’s cited setup guidance does not promise a universal glass-to-glass figure. Measure from the source event to playback on the actual network and player you intend to use.

Support for VISCA over IP encoder workflows enables flexible PTZ control, while the dashboard provides video preview and system status.
Keep SRT contribution settings separate
SRT is a transport workflow for contribution into or out of Elemental Live, not a replacement for the DASH chunked-output configuration. SRT latency coordinates packet-recovery buffering between endpoints, so choose it with the other system’s administrator rather than assuming a fixed value.
SRT input
For an SRT input, coordinate the address and port, encryption and passphrase if used, any required stream ID, and preferred latency with the upstream administrator. See AWS’s SRT input setup and SRT input prerequisites.

SRT output
For SRT output, coordinate the destination address and port, caller/listener roles, latency, network access, and encryption with the downstream administrator. Elemental Live is the sender in either caller/listener arrangement; the caller initiates the handshake. AWS documents these details in its guides to delivering TS using SRT and creating the output.
When sending Reliable TS to an AWS Elemental MediaConnect flow, AWS recommends choosing the MediaConnect option in Reliable TS rather than its SRT option, which is intended for downstream systems other than MediaConnect.

LL-HLS is a different delivery workflow
AWS documents LL-HLS through MediaPackage and CloudFront separately from Elemental Live’s chunked DASH output. For CloudFront manifest requests used for LL-HLS blocking playlists, forward the _HLS_msn and _HLS_part query strings. Those are CloudFront/LL-HLS delivery considerations, not additional switches for the DASH procedure above. See AWS’s live streaming guide and Guidance for Live Streaming on AWS.
Troubleshoot common setup problems
- The Chunked Transfer field is missing: Select the appropriate HTTP Push Dialect; AWS notes that the field appears after this selection.
- The destination rejects or mishandles the output: Confirm that the receiver supports chunked DASH and that its administrator has prepared it for the output. Check the destination’s accepted requirements before changing fragment or segment lengths.
- Playback is not noticeably faster: Check whether the receiver, packaging/delivery chain, player, and network support and preserve the fragment behavior. Measure end-to-end latency in the deployed chain; the encoder settings alone cannot establish the result.
- An SRT link has recovery or connectivity issues: Coordinate endpoint roles, address and port, network access, encryption details, stream ID where applicable, and latency with the other endpoint. Do not treat SRT latency as a DASH chunked-output control.
- LL-HLS blocking playlist requests do not behave as expected through CloudFront: Check that
_HLS_msnand_HLS_partare forwarded in manifest requests as required by the LL-HLS workflow.
Or let it run in the cloud
Elemental Live’s procedure above is for configuring an encoder output and a compatible delivery chain. If your goal instead is to keep a pre-recorded YouTube channel live around the clock, StreamNeo is a separate cloud service: upload a recording or build a playlist, add your YouTube stream key, and go live. It plays uploaded videos, not a live camera feed.
