Embodiment Construction

[0104] In order to make the technical solutions and advantages of the embodiments of the present invention more clear, the specific technical solutions of the invention will be further described in detail below in conjunction with the drawings in the embodiments of the present invention. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0105] In order to better understand the embodiment of the present invention, the code rate, frame rate and resolution and their interrelationships are described here.

[0106] Code rate: the number of data bits transmitted per unit time during data transmission, and the general unit is kilobitsper second (kbps). The popular understanding is the sampling rate. The larger the sampling rate per unit time, the higher the precision, and the closer the processed file is to the original file, that is to say, the richer the details of the picture.

Abstract

The embodiment of the invention provides a video transcoding method and device, a server and a readable storage medium. The method comprises the steps of: determining video sub plates to be transcodedand attribute parameters to the transcoded, wherein the attribute parameters to the transcoded comprise pre-coding parameters and coding parameters corresponding to target definition; performing pre-coding of the video sub plates to be transcoded according to the pre-coding parameters to obtain a first coding result; and coding the first pre-coding result according to the coding parameters corresponding to the target definition to obtain a second coding result; and outputting the second coding result.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a video transcoding method and its device, a server, and a readable storage medium. Background technique [0002] With the development of network bandwidth and terminal equipment, the number of users of online video is increasing rapidly. At present, watching online video has become the first choice for more and more users for leisure and entertainment. Due to differences in network environments, terminal types, and uploaded video content formats, videos on video websites must be transcoded before they go online, and multiple-definition videos are output to meet the needs of various network and terminal environments. [0003] Users often switch resolutions due to different network environments during playback. If instantaneous decoding refresh (Instantaneous Decoding Refresh, IDR) alignment transcoding of multiple resolutions is implemented, switching resolutions can...
