Problems solved by technology

[0003] The existing video transcoding technology is that one terminal alone completes the transcoding of one or more videos. Since there are a large number of videos that need to be transcoded, one terminal needs to transcode multiple videos at a time. The original bitrates of different videos are different, but the terminal transcoding standard is the same, which causes the bitrates of the transcoded videos to be uneven. However, the viewing effect provided by the video with a too low bit rate cannot meet the requirements of the viewers.
Moreover, since one terminal transcodes multiple videos at one time, the load on the terminal is increased, the idle computing and processing capacity of the terminal cannot be fully utilized, the time required for transcoding is prolonged, and the efficiency of video transcoding is too low

Embodiment 1

[0057] Such as figure 2 As shown, the embodiment of the present invention provides a video processing method, and the specific implementation steps are as follows:

[0058] In step 201, check whether there is a video file to be transcoded, if there is a video file to be transcoded, then execute step 202; if there is no video file to be transcoded, then end the process.

[0059] In step 202, a video file to be transcoded is acquired.

[0060] In step 203, select an idle assisting end from the assisting ends participating in conversion, associate the video file to be transcoded with the selected assisting end, and mark the selected assisting end as occupied. If the host side is set to participate in transcoding, the assisting side can also be the host side.

[0061] When there are at least two assisting ends marked as idle, the step of selecting the assisting end in the idle state from the assisting ends participating in the conversion: arranging at least two assisting ends i...

Embodiment 2

[0077] Such as image 3 As shown, the embodiment of the present invention provides a video processing method, and the specific implementation steps are as follows:

[0078] In step 301, the average code rate of transcoded video files is calculated.

[0079] Among them, b avr Indicates the average bit rate, k indicates the number of currently transcoded video files, b i Indicates the bit rate of the i-th video file.

[0080] In step 302, the floating range of the initial code rate is determined according to the preset initial code rate and the preset floating rate.

[0081] If the initial code rate is set to 400 and the preset floating rate is ±30%, the floating range of the initial code rate is 280

[0082] In step 303, the relationship between the average code rate and the floating range of the initial code rate is determined.

[0083] In step 304, when the average code rate is greater than the maximum value in the floating range of the initial code rate, reduce ...

Embodiment 3

[0091] Such as Figure 4 As shown, the embodiment of the present invention provides a video processing method, which improves video transcoding efficiency by segmenting and transcoding a large video file. The specific implementation steps are as follows:

[0092] In step 401, the file size of the video file to be transcoded is acquired.

[0093] The file size of the obtained video file to be transcoded is 2.3G.

[0094] In step 402, it is judged whether the file size is greater than a preset threshold. When the size of the video file is greater than the preset threshold, step 403 is executed; when the size of the video file is smaller than the preset threshold, the process ends.

[0095] The preset threshold is 2.0G, and the file size of the video file to be transcoded is larger than the preset threshold.

[0096] In step 403, when the size of the video file is larger than the preset threshold, the video file is divided into n divided files, wherein, n=X / Y+1, X is the file...

Abstract

The invention discloses a video processing method, device and system, wherein the video processing method, device and system are used for a host side and used for improving the video transcoding efficiency and balancing and controlling the final code rates of all videos. The method includes the steps of obtaining a video file to be transcoded, obtaining an assisting side marked in an idle state, determining the target code rate of the video file to be transcoded, sending the video file to be transcoded and the target code rate to the assisting side, and marking the assisting side in an occupied state, and receiving the transcoded video file sent by the assisting side, wherein the assisting side is used for converting the code rate of the video file to be transcoded into the target code rate.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a video processing method, device and system. Background technique [0002] As for the provision of video, the video types and video scenes it provides are ever-changing. As a video viewer, the access bandwidth and access network are also different when watching a video. In order to meet the user's viewing needs, the final bit rate of the video is usually controlled within a suitable range. [0003] The existing video transcoding technology is that one terminal alone completes the transcoding of one or more videos. Since there are a large number of videos that need to be transcoded, one terminal needs to transcode multiple videos at a time. The original bitrates of different videos are different, but the terminal transcoding standard is the same, which causes the bitrates of the transcoded videos to be uneven. However, the viewing effect provided by a video with a...
