aws mediaconvert

aws上で

• 動画の合成
• 動画の作成
• 音声の作成

ができるサービス

特にジョブの設定jsonではまったので残しておきます

おすすめはgptなどで生成するより、awsのコンソール画面でポチポチしながらジョブのjsonを作成してそれをプログラムに落とし込む方が全然早いことに気が付きました

必要なrole

# IAMロールの作成

  name = "MediaConvertRole"

  assume_role_policy = <<EOF
{
  "Version": "2012-10-17",

    {
      "Effect": "Allow",
      "Principal": {
        "Service": "mediaconvert.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
EOF
}

# IAMポリシーのアタッチ
resource "aws_iam_role_policy" "mediaconvert_policy" {
  role = aws_iam_role.mediaconvert_role.name

  policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [

      ],
      "Resource": "arn:aws:s3:::vision-maker-dev/*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "mediaconvert:CreateJob",
        "mediaconvert:GetJob",
        "mediaconvert:ListJobs"
      ],
      "Resource": "*"
    }
  ]
}
EOF
}

# MediaConvertのキュー
resource "aws_mediaconvert_queue" "default_queue" {
  name = "default"
}

output "mediaconvert_role_arn" {
  value = aws_iam_role.mediaconvert_role.arn
}
