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...
