Abstract

The invention discloses a video file processing method, a video file processing device and a video file processing system. The video file processing method comprises the following steps of: receiving a transcoding request message from a client by using a metadata server, wherein the transcoding request message comprises the metadata information of a source file fragment and a target coding format; acquiring the metadata information of a target file fragment corresponding to the metadata information of the source file fragment according to the metadata information of the source file fragment; and if a coding format of the target file fragment is the same as the target coding format in the transcoding request message, transmitting the metadata information of the target file fragment to the client, so that the client can acquire the target file fragment corresponding to the metadata information of the target file fragment according to the metadata information of the target file fragment. Network input and output operation can be reduced, and the application performance of video transcoding can be improved.

Description

technical field

[0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a video file processing method, device, and system. Background technique

[0002] usually, figure 1 It is a schematic structural diagram of an existing distributed video transcoding system, such as figure 1 As shown, the processing node that runs the transcoding application, the client that uploads the source file, and the storage node that saves the target file transcoded by the processing node are connected through the network, and the processing node reads source file fragments from the client and writes During the process of object file fragmentation, network bandwidth is occupied. Therefore, based on the existing distributed file system, a large number of unnecessary network input and output (Input / Output) operations are caused. When the network bandwidth is poor, the performance of the video transcoding application will drop sharply. Especial...
