Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] In one embodiment, such as figure 1 As shown, the method includes:

[0033] Step S102, receiving the input video stream data, and acquiring the encoding type of the video stream data.

[0034] The video stream data is the stream data of the input video file. The encoding type of the video stream data is the format type of the input video file. For example, if the suffix of the input video file to be transcoded is mp4, the encoding type of the video stream data of the video file is MPEG-4 (Moving Pictures Experts Group / Motion Pictures Experts Group, Motion Picture Experts Group) . The en...

Abstract

The invention provides a video transcoding method which comprises the steps that input video stream data are received, and a coding type of the video stream data is acquired; sub data blocks are generated according to video stream data slices, and file information corresponding to the coding type is added to the sub data blocks to obtain video subfiles, wherein the file information comprises head information and tail information; the video subfiles are transcoded in a parallel mode, and the video subfiles obtained after transcoding are synthesized into a video file. In addition, the invention further provides a video transcoding device. The video transcoding method and device improve video transcoding efficiency.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video transcoding method and device. Background technique [0002] At present, for various reasons such as different application fields, different needs of users, and different playback terminals used, it is necessary to transcode video source files to obtain video files that meet the requirements. For example, fields such as transportation, security, monitoring, and film and television have high requirements for video quality, and require videos with high resolution and bit rate; and mobile devices generally need to transcode video source files to lower resolution due to limited storage space. video files to reduce the storage space occupied by the video and make it easy to transfer. [0003] However, in the traditional transcoding method, the input video stream data can only be transcoded through a single thread, which is inefficient, and the larger the vide...
