Encoder installieren

Für die API benötigst du einen Encoder, um Eingabestreams zu generieren die die API verarbeitet.

ffmpeg als diese Seite installieren behandelt die Verwendung von ffmpeg zum Generieren von Eingabestreams. Sie können dies installieren in Cloud Shell mit dem folgenden Befehl ausführen.

sudo apt install ffmpeg

Eingabeendpunkt erstellen

Um einen Livestream zu starten, musst du zuerst das projects.locations.inputs.create Methode zum Erstellen eines Eingabeendpunkts. Sie senden den Eingabestream an diesen Endpunkt.

REST

Ersetzen Sie diese Werte in den folgenden Anfragedaten:

PROJECT_NUMBER: Ihr Google Cloud-Projekt Zahl; Sie finden sie im Feld Projektnummer auf der Seite IAM-Einstellungen
LOCATION: der Ort, an dem die Eingabe erstellt werden soll endpoint; eine der unterstützten Regionen verwenden
Standorte anzeigen
- us-central1
- us-east1
- us-east4
- us-west1
- us-west2
- northamerica-northeast1
- southamerica-east1
- asia-east1
- asia-east2
- asia-northeast1
- asia-southeast1
- australia-southeast1
- europe-west1
- europe-west2
- europe-west3
- europe-west4
INPUT_ID: Eine benutzerdefinierte Kennung für den neuen zu erstellenden Eingabeendpunkt, an den Sie Ihren Eingabestream senden. Dieser Wert muss 1–63 Zeichen lang sein und mit [a-z0-9] beginnen und enden. kann Bindestriche (-) zwischen den Zeichen enthalten. Beispiel: my-input

Wenn Sie die Anfrage senden möchten, maximieren Sie eine der folgenden Optionen:

curl (Linux, macOS oder Cloud Shell)

Hinweis: Der folgende Befehl setzt voraus, dass Sie sich mit Ihrem Nutzerkonto bei der gcloud-Befehlszeile angemeldet haben. Dazu haben Sie gcloud init oder gcloud auth login ausgeführt oder die Cloud Shell genutzt, die Sie automatisch bei der gcloud-Befehlszeile anmeldet. Um herauszufinden, welches Konto gerade aktiv ist, führen Sie gcloud auth list aus.

Speichern Sie den Anfragetext in einer Datei mit dem Namen request.json. Führen Sie folgenden Befehl im Terminal aus, um diese Datei im aktuellen Verzeichnis zu erstellen oder zu überschreiben:

cat > request.json << 'EOF'
{
  "type": "RTMP_PUSH"
}
EOF

Führen Sie dann folgenden Befehl aus, um Ihre REST-Anfrage zu senden:

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

Eingabestream senden

Rufe wie zuvor die Informationen zum Kanal ab, um festzustellen, ob der Kanal gestartet wurde. Die Antwort sollte Folgendes enthalten:

{
  ...
  "streamingState": "AWAITING_INPUT"
  ...
}

Da der Kanal nun bereit ist, senden Sie einen Testeingabestream an den Eingabeendpunkt, um den Livestream zu generieren.

Öffnen Sie ein neues Terminalfenster. Führen Sie den folgenden Befehl mit der Methode INPUT_STREAM_URI vom Prüfen Sie den Ergebnisbereich:

ffmpeg -re -f lavfi -i "testsrc=size=1280x720 [out0]; sine=frequency=500 [out1]" \
  -acodec aac -vcodec h264 -f flv INPUT_STREAM_URI

Prüfen, ob der Kanal streamt

So prüfst du den Status des Livestreamings: die Kanalinformationen abrufen. Die Antwort sollte Folgendes enthalten:

{
  ...
  "streamingState": "STREAMING"
  ...
}

Inhalt im Cloud Storage-Bucket prüfen

Öffnen Sie den Cloud Storage-Bucket. Prüfen Sie, ob die folgenden Dateien und Verzeichnisse vorhanden sind:

main.mpd
mux_audio/
- Mehrere segment-segment-number.m4s-Dateien
- Eine einzelne segment-initialization_segment_0000000000.m4s Datei
mux_video/
- Mehrere segment-segment-number.m4s-Dateien
- Eine einzelne segment-initialization_segment_0000000000.m4s Datei

Generierten Livestream wiedergeben

Führen Sie die folgenden Schritte aus, um die generierte Mediadatei in Shaka Player abzuspielen:

Machen Sie den von Ihnen erstellten Cloud Storage-Bucket öffentlich.
So aktivieren Sie Cross-Origin Resource Sharing (CORS) für einen Cloud Storage-Bucket:
1. Erstellen Sie eine JSON-Datei, die Folgendes enthält:
```
[
  {
    "origin": ["https://shaka-player-demo.appspot.com/"],
    "responseHeader": ["Content-Type", "Range"],
    "method": ["GET", "HEAD"],
    "maxAgeSeconds": 3600
  }
]
```
2. Führen Sie den folgenden Befehl aus, nachdem Sie JSON_FILE_NAME durch den Namen der im vorherigen Schritt erstellten JSON-Datei ersetzt haben:
```
gcloud storage buckets update gs://BUCKET_NAME --cors-file=JSON_FILE_NAME.json
```
Suchen Sie im Cloud Storage-Bucket nach dem generierten main.mpd -Datei. Klicken Sie in der Spalte Öffentlicher Zugriff der Datei auf URL kopieren.
Rufen Sie Shaka Player, ein Online-Livestream-Player, auf.
Klicken Sie in der Navigationsleiste oben auf Benutzerdefinierte Inhalte.
Klicken Sie auf die Schaltfläche +.
Fügen Sie die öffentliche URL der Datei in das Feld URL manifestieren ein.
Geben Sie einen Namen in das Feld Name ein.
Klicken Sie auf Speichern.
Klicken Sie auf Wiedergabe.

Während des Livestreams sollte ein Testmuster wiedergegeben werden.

Video zum Testen des Musters

Eine Werbeunterbrechungsmarkierung im Livestream hinzufügen

Verwenden Sie die Methode projects.locations.channels.events.create , um dem Livestream eine Werbeunterbrechungsmarkierung hinzuzufügen.

Prüfen, ob die Markierung für die Werbeunterbrechung vorhanden ist

Wenn die Anzeigenmarkierung in den Livestream eingefügt wird, erscheint ein Ereignis mit der Bezeichnung <SpliceInfoSection> wird im DASH-Manifest für die angegebene Anzeige angezeigt Dauer (100 Sek.)

Führen Sie den folgenden Befehl aus, um den Inhalt des generierten DASH-Manifests anzuzeigen:

gcloud storage cat gs://BUCKET_NAME/main.mpd

Möglicherweise müssen Sie den Befehl gcloud storage cat mehrmals ausführen, bis der Bereich <SpliceInfoSection> angezeigt wird:

<EventStream timescale="10000000" schemeIdUri="urn:scte:scte35:2013:xml">
