Exemples de configuration

Cette page présente des exemples de configuration pour l'encodage d'un fichier multimédia d'entrée (c'est-à-dire un ElementaryStream).

Flux vidéo

Les propriétés VideoStream n'ont pas de dépendances les unes envers les autres. Vous pouvez définir des propriétés telles que la résolution (hauteur et largeur), le débit et la fréquence d'images indépendamment.

{
  "videoStream": {
    "h264": {
      "profile": "high",
      "preset": "veryfast",
      "heightPixels": 360,
      "widthPixels": 640,
      "pixelFormat": "yuv420p",
      "bitrateBps": 550000,
      "rateControlMode": "vbr",
      "crfLevel": 21,
      "vbvSizeBits": 550000,
      "vbvFullnessBits": 495000,
      "gopDuration": "3s",
      "entropyCoder": "cabac",
      "bFrameCount": 3,
      "frameRate": 30,
      "aqStrength": 1
    }
  },
  "key": "video-stream0"
}

Flux audio

Certaines propriétés AudioStream dépendent les unes des autres. La valeur de la propriété channelCount doit être égale au nombre de dispositions dans le tableau channelLayout. Cette valeur doit également correspondre au nombre de canaux dans un flux d'entrée mappé.

Flux audio de base

Voici un exemple de flux audio non mappé et non mixé.

{
  "audioStream": {
    "codec": "aac",
    "bitrateBps": 64000,
    "channelCount": 2,
    "channelLayout": [
      "fl",
      "fr"
    ],
    "sampleRateHertz": 48000,
    "languageCode": "en-US",
    "displayName": "English"
  },
  "key": "audio-stream0"
}

Flux audio avec mise en correspondance

Voici un exemple de flux audio mappé d'entrée. Le signal stéréo AudioStream de sortie est composé des entrées suivantes :

  • Titre 1
    • Canal 0
  • Titre 1
    • Canal 1

Notez que la valeur de la propriété channelCount doit être égale au nombre d'objets défini sous mapping, chacun avec son propre outputChannel.

{
  "key":  "audio-stream0",
  "audioStream": {
    "codec": "aac",
    "bitrateBps": 64000,
    "channelCount": 2,
    "channelLayout": [
      "fl",
      "fr"
    ],
    "sampleRateHertz": 48000,
    "languageCode": "en-US",
    "displayName": "English",
    "mapping": [
      {
        "atomKey": "atom0",
        "inputKey": "video_and_stereo_audio",
        "inputTrack": 1,
        "inputChannel": 0,
        "outputChannel": 0,
        "gainDb": 0
      },
      {
        "atomKey": "atom0",
        "inputKey": "video_and_stereo_audio",
        "inputTrack": 1,
        "inputChannel": 1,
        "outputChannel": 1,
        "gainDb": 0
      }
    ]
  }
}

Flux audio avec mixage

Voici un exemple de flux audio avec mixage. Le signal stéréo AudioStream de sortie est composé des entrées suivantes :

  • Titre 2
    • Canal 0
    • Canal 2
    • Canal 4
  • Titre 2
    • Canal 1
    • Canal 3
    • Canal 5

      }
    ],

  }
}

Flux audio multilingues à partir d'un seul fichier

Vous trouverez ci-dessous un exemple de configuration pour un seul fichier vidéo d'entrée contenant une vidéo et plusieurs pistes audio dans différentes langues. L'objet mapping[] permet de créer plusieurs flux audio de sortie, un par langue. La vidéo et chaque flux audio sont inclus à la fois dans les fichiers manifestes HLS et DASH.

Flux audio multilingues à partir de plusieurs fichiers audio

Voici un exemple de configuration pour un fichier vidéo d'entrée contenant une vidéo et une seule piste audio dans la langue par défaut. Deux fichiers audio d'entrée distincts sont également utilisés, un par langue. L'objet mapping[] permet de créer plusieurs flux audio de sortie, un par langue. La vidéo et chaque flux audio sont inclus à la fois dans les fichiers manifestes HLS et DASH.

Flux de texte

Les propriétés TextStream n'ont pas de dépendances les unes envers les autres. Vous pouvez définir les propriétés indépendamment.

Les flux de texte peuvent utiliser une liste d'édition pour modifier le fichier de sortie. Les sections suivantes mettent en évidence l'utilisation de la liste d'édition pour fournir des sous-titres.

L'exemple suivant montre un flux de texte avec un élément atom dans la liste d'édition.

L'exemple suivant montre un flux de texte avec deux éléments atom dans la liste d'édition.

{
  "editList":[
     {
        "key":"atom0",
        "inputs":[
           "video_input0",
           "caption_input0"
        ],

        "endTimeOffset":"300s"
     },
     {
        "key":"atom1",
        "inputs":[
           "video_input1",

Avancé

Les sections suivantes décrivent diverses configurations avancées.

Sortie audio uniquement

La configuration suivante génère des fichiers MP4 et TS audio uniquement.

{
  "config": {
    "inputs": [
      {
        "key": "input0",
        "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_INPUT_VIDEO"
      }
    ],
    "elementaryStreams": [
      {
        "key": "audio-stream0",
        "audioStream": {
          "codec": "aac",
          "bitrateBps": 64000,
          "languageCode": "en-US",
          "displayName": "English"
        }
      }
    ],
    "muxStreams": [
      {
        "key": "audio-only-ts",
        "fileName": "audio-only.ts",
        "container": "ts",
        "elementaryStreams": [
          "audio-stream0"
        ]
      },
      {
        "key": "audio-only-mp4",
        "fileName": "audio-only.mp4",
        "container": "mp4",
        "elementaryStreams": [
          "audio-stream0"
        ]
      }
    ],
    "manifests": [
    {
      "fileName": "manifest.m3u8",
      "type": "HLS",
      "muxStreams": [
        "audio-only-ts"
      ]
    }
    ],
    "output": {
      "uri": "gs://STORAGE_BUCKET_NAME/STORAGE_OUTPUT_FOLDER/"
    }
  }
}

MuxStream et fmp4

Un MuxStream qui utilise le conteneur fmp4 ne peut contenir qu'un seul flux ElementaryStream. Pour ce conteneur, utilisez deux flux MuxStreams : un pour l'audio et un pour la vidéo :

"muxStreams":[
  {
    "key": "hd3-video",
    "container": "fmp4",
    "elementaryStreams":["video-stream1"]
  },
  {
    "key": "hd3-audio",
    "container": "fmp4",
    "elementaryStreams":["audio-stream1"]
  }
],

Réutiliser des flux dans plusieurs fichiers manifestes

    }
  }
}

Paramètres recommandés pour le transcodage de plusieurs profils

Pour la résolution et le débit de sortie, en fonction de la résolution/fréquence d'images d'entrée (50/60 FPS), ajoutez l'étape de fréquence d'images la plus élevée pour 50/60 FPS, le cas échéant. Notez que l'ajout d'étapes supplémentaires nécessite plus de puissance de calcul. Voici l'échelle recommandée:

Résolution (ScanMode)/Fréquence d'images Débit (kbit/s) du profil H.264 High Profile
170x96 p12/15 130
256 x 144 p25/30 240
416x234 p25/30 300
640 x 360 p25/30 400
768 x 432 p25/30 750
768 x 432 p25/30 1100
960 x 540 p25/30 2200
1 280 x 720 p25/30 3300
1 280 x 720 p50/60 5500
1 920 x 1 080 p25/30 6000
1 920 x 1 080 p50/60 9000

Pour l'audio, les recommandations sont basées sur le nombre de canaux:

Canaux Débit AAC (kbit/s)
2.0 64
2.0 160
5,1 384

Utilisez cette échelle de sortie pour créer une configuration qui génère des fichiers manifestes HLS et MPEG-DASH avec différentes combinaisons:
