Crea y administra recursos

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

Formatos multimedia compatibles

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

Cómo ingresar contenido multimedia	Formatos admitidos
Formatos de archivo de video	MP4, MPEG-TS, 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 activo

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

REST

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

PROJECT_NUMBER: Es el número de 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 activo. Usa una de las regiones compatibles.
Cómo mostrar ubicaciones
- us-central1
- us-east1
- us-east4
- us-west1
- us-west2

- asia-south1
- asia-northeast1
- asia-southeast1
- australia-southeast1
- europe-north1
- europe-west1
- europe-west2
- europe-west3
- europe-west4
ASSET_ID: Es un identificador definido por el usuario para el recurso nuevo 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 tu bucket de Cloud Storage que deseas usar, como gs://my-bucket/my-video.mp4 (consulta los formatos multimedia admitidos).

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)

Nota: El siguiente comando supone que accediste a la CLI de gcloud con tu cuenta de usuario mediante la ejecución de gcloud init o gcloud auth login. 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:

@'
{
  "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",

Cómo borrar un activo

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: Es el número de proyecto de Google Cloud, que se encuentra en el campo Número de proyecto de la página Configuración de IAM.
LOCATION: Es la ubicación de tu recurso. Usa una de las regiones compatibles.
Cómo mostrar ubicaciones
- us-central1
- us-east1
- us-east4
- us-west1
- us-west2
- northamerica-northeast1
- southamerica-east1
- asia-east1
- asia-east2
- asia-south1
- asia-northeast1
- asia-southeast1
- australia-southeast1
- europe-north1
- europe-west1
- europe-west2
- europe-west3
- europe-west4
ASSET_ID: Es el identificador definido por el usuario para el activo.

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:
