Alias konfigurasi dengan contoh MediaTailor penggunaan

Contoh berikut menunjukkan bagaimana MediaTailor konfigurasi lengkap dengan alias konfigurasi, permintaan inisialisasi sesi dengan alias, dan aliran pemrosesan untuk alias.

contoh Konfigurasi lengkap dengan alias

Contoh berikut menunjukkan konfigurasi lengkap yang mencakup alias konfigurasi dan variabel domain dinamis:

PUT /playbackConfiguration

    "Name": "aliasedConfig",
    "AdDecisionServerUrl": "https://abc.execute-api.us-west-2.amazonaws.com/ads?sid=[session.id]&ad_type=[player_params.ad_type]",
    "VideoContentSourceUrl": "https://[player_params.origin_domain].mediapackage.[player_params.region].amazonaws.com/out/v1/[player_params.endpoint_id]",
    
    "AdSegmentUrlPrefix": "https://[player_params.ad_cdn_domain]/ads/",
    "ContentSegmentUrlPrefix": "https://[player_params.content_cdn_domain]/content/",
    "TranscodeProfileName": "[player_params.transcode_profile]",
    "SlateAdUrl": "https://[player_params.slate_domain]/slate/[player_params.slate_type].mp4",
    "StartUrl": "https://[player_params.tracking_domain]/start?session=[session.id]",

            "tv": "4k_profile"
        },
        "player_params.slate_domain": {
            "pdx": "slate-west.example.com",
            "iad": "slate-east.example.com"
        },
        "player_params.slate_type": {
            "standard": "default_slate",

            "pdx": "tracking-west.example.com",
            "iad": "tracking-east.example.com"
        }
    }
}

contoh Inisialisasi sesi dengan alias

Contoh berikut menunjukkan permintaan inisialisasi sesi yang menentukan variabel pemain dan alias:

POST master.m3u8
{
    "playerParams": {
        "origin_domain": "pdx",
        "region": "pdx", 
        "endpoint_id": "pdx",
        "ad_type": "customized",
        "ad_cdn_domain": "pdx",
        "content_cdn_domain": "pdx",
        "transcode_profile": "mobile",
        "slate_domain": "pdx",
        "slate_type": "branded",
        "tracking_domain": "pdx"
    }
}

contoh Aliran pemrosesan parameter

Dalam contoh berikut, MediaTailor mengganti string alias dengan nilai yang dipetakan dalam alias konfigurasi. Pemrosesan menghasilkan permintaan berikut:

• Permintaan ADS:

  https://abc.execute-api.us-west-2.amazonaws.com/ads?sid=[session.id]&ad_type=abc12345

• VideoContentSource permintaan:

  https://abc.mediapackage.us-west-2.amazonaws.com/out/v1/abcd

• AdSegmentUrlPrefix:

  https://ads-west.cdn.example.com/ads/

• ContentSegmentUrlPrefix:

  https://content-west.cdn.example.com/content/

• TranscodeProfileName:

  mobile_optimized

• SlateAdUrl:

  https://slate-west.example.com/slate/brand_slate.mp4

• StartUrl:

  https://tracking-west.example.com/start?session=[session.id]

• EndUrl:

  https://tracking-west.example.com/end?session=[session.id]
