Embodiment Construction

[0034] Such as figure 1 As shown, a video adaptive transcoding method comprises the following steps:

[0035] Step S10, receiving a video request from a user, and obtaining configuration information of the user terminal. The user's video request includes relevant information of the video requested by the user, such as video name, video type, video description information, etc., and corresponding video resources are searched according to the relevant information. The configuration information of the client includes the playback resolution of the client, the network bandwidth between the client and the server, the playback software used by the client, the video mode used by the user, and the priority of the user.

[0036] The client can be a terminal device such as a mobile communication terminal, a personal computer, or a personal digital assistant. The playback resolution of the client refers to the resolution at which the device at the client plays video; the network bandwid...

Abstract

The invention relates to a video self-adaptive transcoding method which comprises the following steps: receiving a video request of a user, and obtaining configuration information of a client; searching video resources according to the video request; obtaining transcoding demands of a video according to the configuration information; and transcoding the searched video according to the transcoding demands. The invention further provides a video self-adaptive transcoding system. The method and the system can lead the video after the transcoding to be applicable to the client, and further meet the video transcoding demands of the different clients.

Description

【Technical field】 [0001] The present invention relates to the technical field of video transcoding, in particular to a video adaptive transcoding method and system. 【Background technique】 [0002] Video transcoding refers to converting a video with a certain resolution (or bit rate, playback format, etc.) to another resolution (or bit rate, playback format, etc.). In order to adapt to different terminal devices and different network environments, the video is usually transcoded and then sent to the corresponding terminal for playback. Due to the difference in hardware environment, network environment and playback software of the terminal, the required resolution, bit rate and playback format are often different. [0003] Traditional video transcoding methods usually set different transcoding requirements (such as resolution, bit rate and playback format) according to different types of terminals. For example, for a video played on a computer, the resolution, bit rate, and ...
