AWS Elemental Link is a camera-feed source for AWS Elemental MediaLive; it is not documented as a direct Amazon IVS encoder. For a Link-based production, the documented path starts with Link and MediaLive, then requires a separately verified downstream configuration to IVS. For the IVS ingest side, use a supported protocol, H.264 video, AAC-LC audio, constant bitrate, and a network connection with adequate headroom. Test the complete handoff and recovery path before relying on it for an event.
How the Link-to-IVS workflow fits together
Think of the workflow as three stages: a source, a processing service, and a destination. Elemental Link sends a live source such as a camera or production equipment to MediaLive over an AWS-managed secure connection. MediaLive ingests and processes that source, then sends configured output to a downstream destination. Amazon IVS is the intended destination here, but AWS documentation reviewed for this setup does not establish a complete Link-fed MediaLive-to-IVS output configuration.

- Source: Elemental Link HD is for HD sources; Link UHD supports HD and UHD sources.
- Processing: MediaLive receives and transcodes the Link input.
- Destination: Amazon IVS accepts configured ingest feeds using RTMPS, RTMP, or SRT for low-latency streaming. Confirm that your specific MediaLive output, IVS channel type, endpoint, and protocol are compatible before production.
Link UHD is also documented as a source for a MediaConnect flow, but that is a separate use case and does not establish a direct Link-to-IVS connection. Do not assume that selecting an IVS endpoint in MediaLive is sufficient: verify the current AWS service documentation for the output group and destination settings you plan to use.

Set up the documented Link and MediaLive source stage
- Choose the device for your source. Use Link HD for an HD source, or Link UHD if your source is UHD or HD. Confirm the device supports the source format you intend to send.
- Align the AWS Region. Plan the Link device, Elemental Link input, and MediaLive channel in the appropriate AWS Region. Region alignment is part of the documented MediaLive input workflow.
- Power and connect the Link device. Connect it to the network and start sending video from the source. AWS notes that operators typically begin sending video before attaching the input to a channel.
- Create the Elemental Link input. In the AWS console, create an Elemental Link input and select the device. Attach that input to the MediaLive channel that will process it.
- Confirm the input is healthy before configuring the destination. Verify that MediaLive is receiving the expected source picture and format. If it is not, troubleshoot the source and Link-to-MediaLive leg first; a downstream IVS change will not repair a missing input.
The console labels and service options can change. Use the current MediaLive and Elemental Link documentation for the precise console workflow in your account and Region.

Verify the MediaLive-to-IVS handoff before production
The crucial configuration is the boundary between MediaLive and IVS. The available AWS guidance establishes that MediaLive can deliver configured outputs and that IVS accepts specified ingest protocols, but it does not establish the exact output group, destination URL, or a complete tested configuration for this particular Link-fed workflow. Treat that handoff as an implementation to validate, not a guaranteed preset.
- Choose the IVS channel type. Check the current channel type and its ingest requirements in the Amazon IVS documentation. Do not assume settings or limits are interchangeable across channel types.
- Choose an ingest protocol supported by the full path. Confirm that the current MediaLive output options and the IVS channel accept the same protocol, and that the required endpoint and port are reachable.
- Configure the destination using current AWS guidance. Obtain the correct IVS ingest endpoint and credentials from the relevant IVS channel configuration. Use the current MediaLive output documentation to determine how those values belong in the chosen output group. Do not reuse credentials from another channel or publish them in logs or shared documentation.
- Run an end-to-end test. Confirm that MediaLive receives the Link feed, IVS receives the outgoing stream, and a viewer can play it. Check both video and audio, then test an interruption and recovery before an event.
- Test failure behavior deliberately. Validate what happens if the source, Link device, MediaLive processing path, network connection, or IVS ingest path fails. Record who can intervene and how the stream is restarted.
MediaLive can be configured with dual independent processing pipelines for resilience within MediaLive. That does not by itself provide a second camera, a second Link device, an independent first-mile network path, or a verified dual-path handoff to IVS. Design and test each failure domain separately.

Choose IVS ingest settings for stability
For Amazon IVS low-latency ingest, AWS documents RTMPS, RTMP, and SRT, along with H.264 video and AAC-LC audio. RTMPS requires TLS 1.2 or later. Confirm the current service requirements for the channel type and encoder or output you use before settling on a production profile.

| Rate control | Use CBR rather than VBR. AWS warns that bitrate spikes can contribute to dropped frames before ingest or buffering during playback. |
| Video scan | Use a progressive signal and avoid interlaced video, as AWS recommends. |
| Keyframe interval | AWS’s getting-started guidance recommends a 2-second interval for its OBS workflow. Check the current requirements for your IVS channel and the encoder or MediaLive output in use. |
| Resolution and bitrate | There is no single safe value for every IVS channel type and source. Check current IVS limits and choose a bitrate the encoder and network can sustain continuously. |
AWS’s IVS streaming configuration documentation says, “Always use CBR (Constant BitRate), not VBR (Variable BitRate), as the rate-control method for encoders.” That is a stability recommendation, not a promise that CBR alone will prevent interruptions.

Plan network capacity and firewall access
AWS recommends a stable upload connection that can sustain the stream, wired networking where possible, and planning for 50% more bandwidth than the minimum required. That extra capacity is headroom for bitrate fluctuations, not a measured reliability guarantee. AWS also recommends a dedicated internet VLAN for encoding equipment where practical.
| Amazon IVS low-latency ingest protocol | Transport and port listed by AWS | Firewall check |
|---|---|---|
| RTMPS | TCP 443 | Permit the required IVS destinations over TCP 443 and verify TLS 1.2 or later. |
| RTMP | TCP 1935 | Permit the required IVS destinations over TCP 1935 if using insecure RTMP; prefer a secure option when supported by the full path. |
| SRT | Port 9000 | Permit the required IVS destinations and SRT traffic on port 9000. |
These ports are not a substitute for the current destination allowlist. AWS warns that limiting access to the documented destinations and ports can disrupt ingest. WebRTC has separate network requirements; do not apply this low-latency RTMP-family table to a WebRTC workflow.

- Check sustained upload capacity while other household or production traffic is active, not only when the network is idle.
- Ask the network administrator to confirm outbound access for the chosen protocol and IVS destinations.
- A wired network connection is the reliability practice AWS recommends; the documentation does not require a specific cable category.
Monitor the stream and troubleshoot interruptions
AWS defines stream starvation as a delay or halt in delivery of content packets to IVS. If IVS receives no broadcaster data for 30 seconds, it terminates the low-latency stream session to allow the broadcaster time to reconnect. Starvation can originate in the encoder, the local network, congestion, internet loss, or another point in transit.

| IVS receives no stream | MediaLive output, endpoint or credentials, protocol compatibility, or firewall access. | Confirm MediaLive is producing output, recheck the current IVS endpoint and channel settings, and verify the selected protocol and outbound port are permitted. |
| Stream starts, then ends after an interruption | Broadcaster data stopped reaching IVS; the source, encoder, network, or public internet path may be involved. | Correlate IVS Stream Health information with MediaLive and encoder logs. Find where packets stopped, then test reconnect and recovery. |
| Viewers see buffering or dropped frames | Bitrate spikes, insufficient upload capacity, encoder overload, or network congestion. | Use CBR, check encoder load and bitrate, confirm the network has the recommended headroom, and reduce encoding demands if the machine is overloaded. |
| Picture is missing or appears wrong | Source format, input health, video configuration, or incompatibility at the processing or ingest stage. | Check the signal at the Link-to-MediaLive input first, then verify the output against current IVS requirements, including progressive video and the supported codec. |
| Stream works on one network but not another | Firewall or egress policy differences. | Compare allowed destinations and ports for the selected protocol with the current IVS firewall guidance; do not assume all networks permit RTMP-family traffic. |
Use IVS Stream Health information and encoder logs together. IVS metrics can show what reached the service; upstream MediaLive, device, and network logs help identify whether the loss began before ingest.
