Abstract
The invention provides a method and a device for caching an MP4 online video. The method comprises the following steps of: 1, identifying different uniform resource locators (URLs) which indicate the same MP4 video request; 2, analyzing the URLs, and extracting an initial position for playing an MP4 video; 3, transmitting a hyper text transfer protocol (HTTP) response message to a client according to the URLs and the initial position; and 4, extracting data acquired by the URLs and the initial position in the HTTP response message for reading a local MP4 video file, and reconfiguring an MP4 video file which is transmitted to the client. By the method and the device, MP4 format video data which are required to be repeatedly acquired through a network outlet can be directly acquired in a local server, the load of the network outlet is reduced, a network bandwidth and traffic consumption are reduced, and operation cost is saved.
Description
[technical field]
The present invention relates to networking technology area, relate in particular to a kind of MP4 Online Video caching method and device.
[background technology]
Because the Flash plug-in unit can be play the MP4 video file, can watch HD video under the limited network bandwidth in order to make the user, the Online Video file of at present a lot of Online Video websites adopts the MP4 file format.Browser is as long as support Flash just can play the MP4 video of high definition.So the MP4 video becomes the Online Video form of present main flow.
MP4 video data demand is generally all larger, and much all is the data of repeatability for the user, and this has brought great burden for user's network egress, has consumed the network bandwidth, has also consumed the flow of network, has increased the cost of operation.
[summary of the invention]
