Synchronizing the storing of streaming video

摘要

A method, system, and computer-readable medium for synchronizing video are described. The system captures video data with a camera, the video data including a first video data segment and a second video data segment. When a network between the camera and a hub is insufficient to allow downstream real-time streaming of the video data, the system stores the first video data segment on a first storage. When the network is sufficient to allow downstream real-time streaming of the video data, the system transfers the second video data segment from the camera to the hub, reads the first video data segment from the first storage, and transfers the first video data segment to the hub. The system stores the video data segments onto a second storage such that a non-real-time playback from the second storage shows the first video data segment and the second video data segment in sequence.

1. A method for synchronizing video comprising:
capturing video data with a camera, the video data including a first video data segment and a second video data segment; when a network between the camera and a hub is insufficient to allow downstream real-time streaming of the video data, storing the first video data segment on a first storage; when the network between the camera and the hub is sufficient to allow downstream real-time streaming of the video data,
transferring the second video data segment from the camera to the hub over the network,reading the first video data segment from the first storage, andtransferring the first video data segment to the hub over the network; storing the first video data segment and the second video data segment onto a second storage such that a non-real-time playback from the second storage shows the first video data segment and the second video data segment in sequence; creating a keyframe index during the storing; and when a playback position is requested and the playback position does not exist in the second storage, using the keyframe index to find a next decodable video data, the next decodable video data being stored in the second storage.
