Abstract
A barrage video live broadcast method is performed at a video source device that is communicatively connected to a network access device and a video capture device. The video source device sends an account distribution request to the network access device and the account distribution request is used to instruct the network access device to return a video source device account bound to the network access device for accessing a barrage video system hosted at a remote server. The video source device then obtains a live video stream captured by the video capture device (e.g., a unmanned aerial vehicle) and sends the live video stream to the network access device by using a Wi-Fi Direction connection. The network access device then forwards the live video stream to the barrage video system for broadcasting the live video stream and live comments submitted from other user accounts of the barrage video system.
