Embodiment Construction

[0034] figure 1 is a flowchart of a video transcoding method according to an embodiment of the present invention. An embodiment of the present invention provides a video transcoding method, which includes:

[0035] Task generating step 100: generating a video transcoding task. The video transcoding task includes the source format of the source video and the target format of the destination video. Since different source formats need different transcoding units to convert to different target formats, the video transcoding task must specify the source format and target format. For example, the source format may be known according to the format of the source video, and the target format may be known according to user requirements of the terminal.

[0036] Start transcoding step 200: start the corresponding transcoding unit according to the source format and the target format.

[0037] Transcoding step 300: the transcoding unit transcodes the source video and outputs the target...

Abstract

The invention provides a video transcoding method and system. Wherein, the method includes: a task generating step: generating a video transcoding task; starting a transcoding step: starting a corresponding transcoding unit according to the source format and a target format; transcoding step: transcoding the source video by the transcoding unit, and outputting the target video ; Transmission step: transmitting the target video to the terminal, so that the terminal can play the target video. The video transcoding method and system of the present invention can automatically generate video transcoding tasks and call corresponding transcoding units to transcode the source video and output the target video, thus realizing automatic video transcoding conveniently and quickly to satisfy users Broadcasting on websites or TV programs, etc.

Description

technical field [0001] The present invention relates to the technical field of video transcoding, in particular to a video transcoding method and system. Background technique [0002] Video coding is widely used in Internet video transmission, digital TV, video conferencing and other occasions. Different applications have different requirements for video codecs, video data storage formats, and network transmission equipment. The coding standards formulated for specific fields are also different, such as: MPEG22 standard for digital TV; H.263 for teleconferencing; MPEG24's ultra-low bit rate coding is more suitable for mobile multimedia applications. In order to enable seamless connection between heterogeneous networks, different access devices, and different multimedia data formats, video transcoding technology is particularly important. For example, in a video-on-demand system, a video server plus a transcoder Finally, people can request video-on-demand services through w...
