Cómo crear y administrar elementos

En esta página, se muestra cómo crear y administrar los activos de la API de Live Stream. Los recursos son imágenes o videos que se pueden usar con la API de Live Stream. Puedes usar un recurso para insertar una lista en una transmisión en vivo.

Formatos multimedia compatibles

La API de Live Stream admite los siguientes códecs de contenido multimedia y formatos para los activos.

Contenido multimedia de entrada	Formatos admitidos
Formatos de archivo de video	MP4, MPEG-TS y FLV
Códecs de video	H.264
Códecs de audio	AAC, AC3, MP2 y MP3
Formatos de archivo de imagen	JPG
Tamaño máximo	250 MB
Resoluciones máximas	1920 × 1080

Configura el proyecto de Google Cloud y la autenticación

Si no creaste un proyecto de Google Cloud ni credenciales, consulta Antes de comenzar.

Crea un recurso

Para crear un recurso, usa el método projects.locations.assets.create. En el siguiente ejemplo, se crea un activo de video.

REST

Antes de usar cualquiera de los datos de solicitud a continuación, realiza los siguientes reemplazos:

PROJECT_NUMBER: El número de tu proyecto de Google Cloud, que se encuentra en el campo Número de proyecto de la página Configuración de IAM
LOCATION: Es la ubicación en la que se creará el recurso. Usa una de las regiones compatibles.
Mostrar ubicaciones
- 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
ASSET_ID: Es un identificador definido por el usuario para el nuevo recurso que se creará. Este valor debe tener entre 1 y 63 caracteres, comenzar y terminar con [a-z0-9] y puede contener guiones (-) entre los caracteres. Por ejemplo, my-asset.
ASSET_URI: Es el URI del video en el bucket de Cloud Storage que se usará, como gs://my-bucket/my-video.mp4 (consulta los formatos de medios compatibles).

Para enviar tu solicitud, expande una de estas opciones:

curl (Linux, macOS o Cloud Shell)

Nota: Con el siguiente comando, se supone que accediste a la CLI de gcloud con tu cuenta de usuario a través de la ejecución de gcloud init o gcloud auth login, o a través del uso de Cloud Shell, que accede de forma automática a la CLI de gcloud. Para comprobar la cuenta activa actual, ejecuta gcloud auth list.

Guarda el cuerpo de la solicitud en un archivo llamado request.json. Ejecuta el comando siguiente en la terminal para crear o reemplazar este archivo en el directorio actual:

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

Luego, ejecuta el siguiente comando para enviar tu solicitud de REST:

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

PowerShell (Windows)

Guarda el cuerpo de la solicitud en un archivo llamado request.json. Ejecuta el comando siguiente en la terminal para crear o reemplazar este archivo en el directorio actual:

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

Luego, ejecuta el siguiente comando para enviar tu solicitud de REST:

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

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -ContentType: "application/json; charset=utf-8" `
    -InFile request.json `
    -Uri "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/assets?assetId=ASSET_ID" | Select-Object -Expand Content

Deberías recibir una respuesta JSON similar a la que se muestra a continuación:

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.video.livestream.v1.OperationMetadata",
    "createTime": CREATE_TIME,
    "target": "projects/PROJECT_NUMBER/locations/LOCATION/assets/ASSET_ID",
    "verb": "create",
    "requestedCancellation": false,
    "apiVersion": "v1"
  },
  "done": false
}

Este comando crea una operación de larga duración (LRO) que puedes usar para realizar un seguimiento del progreso de tu solicitud. Consulta Cómo administrar operaciones de larga duración para obtener más información.

Cómo borrar un recurso

Para borrar un recurso, usa el método projects.locations.assets.delete.

REST

Antes de usar cualquiera de los datos de solicitud a continuación, realiza los siguientes reemplazos:

PROJECT_NUMBER: El número de tu proyecto de Google Cloud, que se encuentra en el campo Número de proyecto de la página Configuración de IAM
LOCATION: Es la ubicación del recurso. Usa una de las regiones compatibles
Mostrar ubicaciones
- 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
ASSET_ID: Es el identificador definido por el usuario para el recurso.

Para enviar tu solicitud, expande una de estas opciones:

curl (Linux, macOS o Cloud Shell)

Ejecuta el siguiente comando:

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

PowerShell (Windows)

Ejecuta el siguiente comando:

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

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

Deberías recibir una respuesta JSON similar a la que se muestra a continuación:

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.video.livestream.v1.OperationMetadata",
