Does VOD Support Transcoding Callbacks?

Yes. VOD uses Simple Message Notification (SMN) to provide event notifications on completed transcoding. Before audio and video transcoding, you can configure event notifications. After the configuration is complete, you can receive a message notification on completed transcoding.

The following types of messages can be received:

  • Template message: If Template message and JSON message are both selected, you will receive template messages via SMS and email, and receive JSON messages via HTTP and HTTPS.
