Nachdem Sie mit der Aufnahme von Streamingdaten in eine bereitgestellte Anwendung begonnen haben, können Sie sich die Ausgabe eines Streams ansehen.
Streamausgaben lesen
Nachdem Sie eine Anwendung erstellt haben, die Ergebnisse in einem Stream speichert, können Sie einen Eingabe- oder Ausgabestream der Datenquelle oder des Modells lesen.
Verwenden Sie den folgenden Befehl, um die Videostream-Ausgabe zu speichern. Mit diesem Befehl werden die Daten aus einem laufenden Livestream gelesen und die Videosegmente im MP4-Dateiformat im vom Nutzer angegebenen Ausgabeverzeichnis gespeichert:
