To configure an AWS Elemental MediaLive HLS input, give MediaLive the URL of an upstream HLS playlist, choose the input class to match your channel, and set the live buffer correctly. That input pulls media into MediaLive; it is not where you paste YouTube’s ingest URL. YouTube is a separate destination configured on the channel’s output side, using the protocol and URL supplied in YouTube Live Control Room.
Know which direction each URL points
An HLS input tells MediaLive to fetch a playlist from an upstream HTTP or HTTPS server. The upstream operator supplies the playlist URL and any credentials needed to access it. By contrast, a YouTube ingest URL is a destination: an encoder sends media to it. Do not paste a YouTube ingest URL into MediaLive’s HLS input field expecting it to pull a source from YouTube.
As an Amazon Associate I earn from qualifying purchases.
Keep the configuration in two parts: first create and attach the upstream HLS input; then configure a supported MediaLive channel output for the YouTube stream. AWS’s input instructions and YouTube’s ingest guidance describe these separate sides, but do not establish that a particular MediaLive channel configuration has been tested end to end.

Create the MediaLive HLS input
- Get the source details. Obtain the upstream HLS playlist URL or URLs from the source operator, along with any required credentials. Confirm that the playlist changes as a live stream runs, rather than pointing to a static video asset.
- Open the input workflow. In the AWS Elemental MediaLive console, open Inputs, choose Create input, enter a name, and set Input type to HLS.
- Choose the input class and source URLs. Match the input class to the planned channel topology. AWS specifies two source URLs for a standard input and one for a single-class input. For a standard configuration, use two genuinely available upstream endpoints; repeating one URL does not create source redundancy.
- Configure credentials if needed. If the HLS server or an encrypted-HLS license server requires credentials, configure them on the input. AWS stores these credentials using Systems Manager Parameter Store password parameters.
- Create the input and attach it. Create the input, then open the MediaLive channel and add the existing input under Input attachments. The channel and input classes must fit the intended pipeline topology.
For the exact console workflow and current field names, see AWS’s instructions for creating an HLS input and its HLS input guidance.

Set the live HLS buffer correctly
For an HTTP or HTTPS HLS source that is live, set Buffer segments to a value from 3 through 10 inclusive. AWS states that a value of 11 or more—or leaving the setting empty—causes MediaLive to treat the input as VOD. AWS does not recommend Amazon S3 as a live source.
Use a value in the documented live range and verify that the playlist is advancing. The right value within that range can depend on the source’s playlist behavior; the cited AWS guidance establishes the valid live range, not a single universally best setting. See AWS’s HLS input settings.

Configure YouTube as the channel destination
- Select or create the YouTube stream. In YouTube Live Control Room, choose the intended stream and its ingest protocol. YouTube’s stream key identifies where the encoder sends the feed and allows YouTube to accept it. Treat the key as a secret; do not publish or share it.
- Choose the protocol required for your workflow. For ordinary encoder streaming, YouTube recommends RTMPS, its encrypted extension to RTMP. Retrieve the RTMPS server URL and stream key from Live Control Room, then enter them in a compatible channel output configuration.
- If using YouTube HLS ingestion, select HLS in YouTube. YouTube provides a stream URL beginning with HTTPS when the selected key uses HLS. Use the URL exactly as issued, including its query fields, and substitute the stream key only where YouTube’s instructions say to do so.
- Validate MediaLive output support and settings. Configure the MediaLive channel’s output only after confirming that its current supported output mode matches the selected YouTube protocol and URL/key requirements. The available documentation does not confirm a tested, end-to-end MediaLive-to-YouTube setup for a specific channel.
For ordinary encoder settings and protocol guidance, see YouTube’s live encoder settings. For HLS ingest selection and details, see YouTube’s HLS ingestion guidance; for stream keys and Live Control Room, see YouTube’s stream setup instructions.

RTMPS or HLS: which YouTube ingest should you use?
| Consideration | RTMPS | HLS |
|---|---|---|
| Role in YouTube guidance | Recommended for ordinary encoder streaming. | An available ingest choice, including for some HDR and codec workflows. |
| Destination values | RTMPS server URL and stream key from Live Control Room. | HTTPS URL and a stream key configured for HLS in Live Control Room. |
| Specific format guidance | YouTube publishes protocol-specific encoder settings. | For the documented HDR/HLS workflow, YouTube requires HTTPS POST/PUT, TS segments, a rolling playlist with no more than five outstanding segments, and segment durations of 1–4 seconds. Byte range is unsupported, and encryption is unsupported except HTTPS. |
| What it means for MediaLive | This is a channel-output/destination choice, separate from the HLS pull input. Confirm the chosen output mode is supported and meets the selected YouTube URL and key requirements. | |
The 1–4 second segment duration and five-segment limit above apply to YouTube’s described HDR/HLS workflow; do not assume they apply to every HLS stream mode. Check the current guidance for the selected stream type.

Apply YouTube’s encoder constraints where relevant
YouTube’s published encoder settings list RTMP/RTMPS protocols; H.264, H.265, or AV1 video; frame rates up to 60 fps; AAC or MP3 audio; and constant bitrate (CBR) encoding. YouTube recommends a 2-second keyframe interval and sets a 4-second maximum. These are YouTube’s published requirements and recommendations, not evidence that a particular MediaLive output has been tested against them. Confirm that the actual channel output matches the settings and protocol shown for your YouTube stream.
Troubleshoot common configuration problems
- MediaLive reports an input or playlist problem: Check that the URL is the upstream HLS playlist, reachable over HTTP or HTTPS, and that any required credentials are correct. Confirm the playlist is changing if it is meant to be live.
- The source behaves like VOD instead of live: Inspect Buffer segments. A blank setting or a value of 11 or more makes MediaLive treat the HLS input as VOD; for a live HTTP/HTTPS source, use 3–10.
- The input topology does not match the channel: Check the input class and source count. AWS specifies two URLs for a standard input and one for a single-class input. A duplicated URL does not provide a second independent endpoint.
- YouTube does not receive the feed: Confirm that the output is configured as a destination, not as the input; that the protocol matches the stream selected in Live Control Room; and that the current URL and key were copied from that stream. Keep the key private.
- An HLS destination is rejected or fails to ingest: Verify that the YouTube key is set to HLS and that the exact HTTPS URL and protocol requirements are used. If the stream is HDR/HLS, check the documented segment format, duration, rolling-playlist, and HTTPS method constraints.
- The destination protocol works in principle but not in this channel: Re-check current MediaLive output support and the channel’s output configuration. YouTube’s encoder requirements alone do not establish that a given MediaLive output setup is supported.
Or let it run in the cloud
If your goal is simply to keep prerecorded video live on YouTube around the clock, StreamNeo is a different route from configuring a MediaLive HLS input: upload a recording or build a playlist, add your YouTube stream key, and go live. StreamNeo loops uploaded videos from the cloud; it does not broadcast a camera feed.
