Questa guida rapida richiede un file manifest MPEG-DASH o HTTP Live Streaming (HLS). Puoi crearne una seguendo una delle guide rapide all'API Live Stream disponibili nella sezione Riproduci il live streaming generato.
Come opzione, puoi utilizzare una rete CDN (Content Delivery Network) con questa guida rapida. Se non hai configurato una CDN, segui i passaggi della guida rapida di Media CDN con le seguenti modifiche:
1. Carica i file manifest e i segmenti multimediali MPEG-DASH o HLS nel bucket Cloud Storage.
2. Non è necessario rendere pubblicamente leggibile il bucket Cloud Storage.
3. Puoi utilizzare URL firmati o non firmati.

Crea una chiave CDN

L'API Video Stitcher può recuperare i video da una rete CDN (Content Delivery Network). Se l'asset video è protetto dalla firma URL, è necessario registrare una chiave CDN con l'API Video Stitcher.

Per registrare la chiave CDN, utilizza il metodo projects.locations.cdnKeys.create.

REST (Media CDN)

Prima di utilizzare i dati della richiesta, effettua le seguenti sostituzioni:

PROJECT_NUMBER: il numero del tuo progetto Google Cloud; si trova nel campo Numero di progetto della pagina Impostazioni IAM
LOCATION: la località in cui creare la chiave CDN; utilizza una delle regioni supportate
Mostra località
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
CDN_KEY_ID: un identificatore definito dall'utente per la chiave CDN, che diventerà il componente finale del nome della risorsa della chiave CDN. Questo ID può contenere solo lettere minuscole, numeri e trattini. Il primo carattere deve essere una lettera, l'ultimo deve essere una lettera o un numero e l'intero ID ha un massimo di 63 caratteri.
HOSTNAME: il nome host della rete CDN da associare a questa chiave CDN (ad esempio, un indirizzo IP come 35.190.60.252 o un nome di dominio come cdn.example.com)
MEDIA_CDN_KEYNAME: il nome del set di chiavi della chiave Media CDN
MEDIA_CDN_PRIVATE_KEY: la chiave privata Ed25519 da 64 byte come stringa con codifica Base64. Per ulteriori informazioni, consulta Creare una chiave privata per Media CDN.

Per inviare la richiesta, espandi una di queste opzioni:

curl (Linux, macOS o Cloud Shell)

Nota: il comando seguente presuppone che tu abbia eseguito l'accesso all'interfaccia a riga di comando gcloud con il tuo account utente eseguendo gcloud init o gcloud auth login oppure utilizzando Cloud Shell, che ti consente di accedere automaticamente all'interfaccia a riga di comando gcloud. Puoi controllare l'account attualmente attivo eseguendo gcloud auth list.

Salva il corpo della richiesta in un file denominato request.json. Esegui questo comando nel terminale per creare o sovrascrivere questo file nella directory attuale:

cat > request.json << 'EOF'
{
  "hostname": "HOSTNAME",
  "mediaCdnKey": {
    "keyName": "MEDIA_CDN_KEYNAME",
    "privateKey": "MEDIA_CDN_PRIVATE_KEY"
  }
}
EOF

Quindi esegui questo comando per inviare la richiesta REST:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \

Controlla il risultato

Per verificare se la chiave CDN è stata creata, utilizza il metodo projects.locations.operations.get. Se la risposta contiene "done: false", ripeti il comando finché la risposta non contiene "done: true".

Prima di utilizzare i dati della richiesta, effettua le seguenti sostituzioni:

PROJECT_NUMBER: il numero del tuo progetto Google Cloud. Si trova nel campo Numero di progetto della pagina Impostazioni IAM.
LOCATION: la località dei dati; utilizza una delle regioni supportate
Mostra località
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
OPERATION_ID: l'identificatore dell'operazione

Per inviare la richiesta, espandi una di queste opzioni:

curl (Linux, macOS o Cloud Shell)

Esegui questo comando:

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID"

PowerShell (Windows)

Esegui questo comando:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID" | Select-Object -Expand Content

Dovresti ricevere una risposta JSON simile alla seguente:

Crea uno slate

L'API Video Stitcher inserisce un video slate predefinito quando non è possibile inserire annunci. Devi registrare il video slate con l'API Video Stitcher per indicare lo slate che verrà utilizzato in assenza di annunci. Il video slate può essere qualsiasi file MP4 con almeno una traccia audio.

Per creare uno slate, usa il metodo projects.locations.slates.create.

REST

Prima di utilizzare i dati della richiesta, effettua le seguenti sostituzioni:

PROJECT_NUMBER: il numero del tuo progetto Google Cloud; si trova nel campo Numero di progetto della pagina Impostazioni IAM
LOCATION: la posizione in cui creare lo slate; utilizza una delle regioni supportate
Mostra località
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
SLATE_ID: un identificatore dello slate definito dall'utente. Questo ID può contenere solo lettere minuscole, numeri e trattini. Il primo carattere deve essere una lettera, l'ultimo deve essere una lettera o un numero e l'intero ID ha un massimo di 63 caratteri.
SLATE_URL: l'URI pubblico di un video MP4 con almeno una traccia audio (video di esempio)

Per inviare la richiesta, espandi una di queste opzioni:

curl (Linux, macOS o Cloud Shell)

Salva il corpo della richiesta in un file denominato request.json. Esegui questo comando nel terminale per creare o sovrascrivere questo file nella directory attuale:

cat > request.json << 'EOF'
{
  "uri": "SLATE_URL"
}
EOF

Quindi esegui questo comando per inviare la richiesta REST:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/slates?slateId=SLATE_ID"

PowerShell (Windows)

Salva il corpo della richiesta in un file denominato request.json. Esegui questo comando nel terminale per creare o sovrascrivere questo file nella directory attuale:

@'
{
  "uri": "SLATE_URL"
}
'@  | Out-File -FilePath request.json -Encoding utf8

Quindi esegui questo comando per inviare la richiesta REST:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `

Crea la configurazione pubblicata

Prima di creare una sessione dal vivo, devi creare una configurazione corrispondente. Molte sessioni dal vivo possono condividere la stessa configurazione.

Per creare la configurazione, utilizza il metodo projects.locations.liveConfigs.create.

REST

Prima di utilizzare i dati della richiesta, effettua le seguenti sostituzioni:

PROJECT_NUMBER: il numero del tuo progetto Google Cloud; si trova nel campo Numero di progetto della pagina Impostazioni IAM
LOCATION: la località in cui creare la configurazione in tempo reale; utilizza una delle regioni supportate
Mostra località
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
LIVE_CONFIG_ID: un identificatore definito dall'utente per la configurazione pubblicata. Questo ID può contenere solo lettere minuscole, numeri e trattini. Il primo carattere deve essere una lettera, l'ultimo deve essere una lettera o un numero e l'intero ID ha un massimo di 63 caratteri.
SOURCE_LIVESTREAM_URI: l'URI del manifest del live streaming; utilizza un URI pubblico o un URI non firmato per il quale hai registrato una chiave CDN
AD_TAG_URI: l'URI pubblico del tag annuncio predefinito. Se non ne hai uno, puoi utilizzare un esempio di tipo singola lineare in linea.
SLATE_ID: l'ID dello slate da utilizzare in assenza di annunci uniti

Per inviare la richiesta, espandi una di queste opzioni:

curl (Linux, macOS o Cloud Shell)

Salva il corpo della richiesta in un file denominato request.json. Esegui questo comando nel terminale per creare o sovrascrivere questo file nella directory attuale:

cat > request.json << 'EOF'
{
  "sourceUri": "SOURCE_LIVESTREAM_URI",
  "adTagUri": "AD_TAG_URI",
  "defaultSlate": "projects/PROJECT_NUMBER/locations/LOCATION/slates/SLATE_ID",
  "adTracking": "SERVER",
  "stitchingPolicy": "CUT_CURRENT"
}
EOF

Quindi esegui questo comando per inviare la richiesta REST:

Dopo aver ricevuto la risposta, puoi riprodurre il live streaming con unione di annunci facendo riferimento all'URI dal campo playUri dell'oggetto risposta.

L'API Video Stitcher genera un ID sessione univoco per ogni richiesta. Una sessione scade se il playUri non viene richiesto negli ultimi 5 minuti.

Riproduci il live streaming con un unico annuncio

Riproduci il live streaming con stitching di annunci utilizzando l'URI del campo playUri dell'oggetto risposta. Per riprodurre questo live streaming nel Player di Shaka, completa i seguenti passaggi:

Apri Shaka Player, un lettore multimediale online.
Fai clic su Custom Content (Contenuti personalizzati) nella barra di navigazione in alto.
Fai clic sul pulsante +.
Incolla il valore del campo playUri (PLAY_URI) nella casella URL manifest.
Digita un nome nella casella Name (Nome).
Fai clic su Salva.
Fai clic su Play (Riproduci).

Inserire interruzioni pubblicitarie

L'API Video Stitcher inserisce gli annunci recuperati dal tag annuncio per ogni interruzione pubblicitaria. Le interruzioni pubblicitarie sono indicate nel manifest utilizzando gli indicatori di annuncio. Gli indicatori degli annunci vengono inseriti dai codificatori del live streaming. Per ulteriori informazioni sugli indicatori di annunci HLS e DASH supportati, consulta la documentazione sugli indicatori di annunci.

Se hai utilizzato l'API Live Stream per creare il tuo live streaming, puoi utilizzare gli eventi del canale per inserire interruzioni pubblicitarie.

Confermare che un annuncio è stato unito

Un annuncio deve essere codificato prima di poter essere unito a una sessione dal vivo. Se vedi un video slate invece di un annuncio, attendi la codifica dell'annuncio e inserisci un'altra interruzione pubblicitaria.

Esegui la pulizia

Per evitare che al tuo account Google Cloud vengano addebitati costi relativi alle risorse utilizzate in questa pagina, elimina il progetto Google Cloud con le risorse.

Elimina la configurazione pubblicata

Per eliminare la configurazione live, esegui questo comando:

REST

Prima di utilizzare i dati della richiesta, effettua le seguenti sostituzioni:

Elimina lo slate

Per eliminare la configurazione dello slate, esegui questo comando:

REST

Prima di utilizzare i dati della richiesta, effettua le seguenti sostituzioni:

PROJECT_NUMBER: il numero del tuo progetto Google Cloud; si trova nel campo Numero di progetto della pagina Impostazioni IAM
LOCATION: la posizione in cui si trova lo slate; utilizza una delle regioni supportate
Mostra località
- us-central1
- us-east1
- us-west1
- asia-east1
- asia-south1
- asia-southeast1
- europe-west1
- southamerica-east1
SLATE_ID: un identificatore dello slate definito dall'utente

Per inviare la richiesta, espandi una di queste opzioni:

curl (Linux, macOS o Cloud Shell)

Esegui questo comando:

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/slates/SLATE_ID"

PowerShell (Windows)

Esegui questo comando:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method DELETE `
    -Headers $headers `
    -Uri "https://videostitcher.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/slates/SLATE_ID" | Select-Object -Expand Content

Dovresti ricevere una risposta JSON simile alla seguente:
