Abstract

The embodiment of the invention provides a video transcoding system and method and a related product. The video transcoding system comprises a main transcoder and a standby transcoder, the main transcoder and the standby transcoder obtain an input video; the input video is transcoded by the main transcoder and then sent to receiving equipment; the standby transcoder caches the input video; the standby transcoder obtains transcoding position information of the main transcoder; and under the condition that the main transcoder is crashed, the standby transcoder transcodes the cached input video according to the transcoding position information to obtain an output video and sends the output video to the receiving equipment. A main transcoder is matched with a standby transcoder; due to the fact that a certain number of data which are not transcoded exist in the transcoding process of the input video data through the main transcoder, the standby transcoder continues to transcode the data which are not transcoded under the condition that the main transcoder is crashed, seamless migration can be achieved, the phenomena of lagging and black screen cannot happen to a receiving end, and higher reliability is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular to a video transcoding method and related products. Background technique [0002] Video transcoding (video transcoding) refers to converting a video code stream into another video code stream to adapt to different network bandwidths, different terminal processing capabilities, and different user needs. Video transcoding is essentially a re-encoding process, so code streams before and after conversion may or may not follow the same video coding standard. [0003] Take the application scenario of large-scale video live broadcast as an example: special personnel collect high-definition original video on site, and then upload it to the background according to high-bandwidth encoding, and then transcode it into streams suitable for different bandwidths and resolutions and send them to the user side for users to choose to watch . The whole process has high re...
