Channel

Source: src/AWS/MediaPackageV2/Channel.ts

An AWS Elemental MediaPackage v2 channel — the entry point for live content into MediaPackage. An encoder (such as AWS Elemental MediaLive) pushes an HLS or CMAF stream to the channel’s ingest endpoints; origin endpoints then package and serve that content downstream.

Creating a Channel

Basic Channel in a Group

import * as MediaPackageV2 from "alchemy/AWS/MediaPackageV2";

const group = yield* MediaPackageV2.ChannelGroup("Live");
const channel = yield* MediaPackageV2.Channel("Feed", {
  channelGroupName: group.channelGroupName,
});

CMAF Ingest Channel

const channel = yield* MediaPackageV2.Channel("Feed", {
  channelGroupName: group.channelGroupName,
  inputType: "CMAF",
  description: "CMAF contribution feed",
});

Resource Policy

const channel = yield* MediaPackageV2.Channel("Feed", {
  channelGroupName: group.channelGroupName,
  policy: JSON.stringify({
    Version: "2012-10-17",
    Statement: [{
      Effect: "Allow",
      Principal: { AWS: "arn:aws:iam::111122223333:root" },
      Action: "mediapackagev2:PutObject",
      Resource: "arn:aws:mediapackagev2:us-east-1:111122223333:channelGroup/live/channel/feed",
    }],
  }),
});

Ingest Endpoints

const channel = yield* MediaPackageV2.Channel("Feed", {
  channelGroupName: group.channelGroupName,
});
// Two redundant ingest endpoints for the encoder to push to.
const urls = channel.ingestEndpoints;
