[0032] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of the video encoding conversion method provided by an embodiment of the present invention. The video encoding conversion method of the embodiment of the present invention can be applied to a terminal, such as intelligent terminal devices like smartphones, laptops, desktop computers, notebook computers, etc. The video encoding conversion method is implemented by an application program, such as a video conversion software, installed on the terminal. Without the need for the user to manually set encoding parameters, it not only saves manpower but also improves the efficiency and accuracy of video conversion. The video encoding conversion method will be described in detail below. As Figure 1 shown, the method includes the following steps S100 - S130.

[0033] S100. Select the first - ranked video file to be converted from the set of video files to be converted according to the file identifier as the current video file to be converted, where the set of video files to be converted includes multiple video files to be converted.

[0034] In the embodiment of the present invention, before the video conversion software performs encoding conversion on the video files to be converted, it will first select the first - ranked video file to be converted from the set of video files to be converted according to the file identifier as the current video file to be converted, where the set of video files to be converted includes multiple video files to be converted. In practical applications, the file identifier is video_Num. For example, video_1, video_2, video_3, etc. Understandably, if there are N video files to be converted, the file identifiers of the N video files to be converted are respectively represented as video_1, video_2, video_3......video_N.

[0035] S110. Obtain video compression information from the current video file to be converted, and calculate encoding parameters corresponding to the current video file to be converted according to the video compression information, the total volume of all video files to be converted in the set of video files to be converted, and the preset total volume of the video output file.

[0036] In an embodiment of the present invention, after using the first video file to be converted as the current video file to be converted, video compression information is obtained from the current video file to be converted, where the video compression information includes parameters such as video volume, GOP value, number of B frames, and video frame rate; the video bit rate in the encoding parameters corresponding to the current video file to be converted is calculated according to the video volume, the total volume of all video files to be converted in the video file set to be converted, and the total volume of the preset video output file; the GOP value, the number of B frames, and the video frame rate in the encoding parameters corresponding to the current video file to be converted are calculated according to the GOP value, the number of B frames, the video frame rate, the total volume, and the total volume of the preset video output file. It should be noted that in the embodiment of the present invention, the GOP value is the interval between two I frames. Understandably, in a video coding sequence, there are mainly three types of coding frames, namely I frames, P frames, and B frames, and I frames, P frames, and B frames represent intra-coded picture frames, predictive-coded picture frames, and bidirectional predictive-coded picture frames, respectively.

[0037] Further, a volume ratio is calculated according to the video volume and the total volume of all video files to be converted in the video file set to be converted; the video bit rate in the encoding parameters corresponding to the current video file to be converted is calculated according to the volume ratio and the total volume of the preset video output file. In practical applications, if it is assumed that the video volume is size_video_N, the total volume is size_Total, and the total volume of the preset video output file is OutputVideo_size, then the volume ratio is size_video_N / size_Total, and the video bit rate Bitrate = size_video_N_Out / duration_video_N, where duration_video_N represents the output duration of the video file, size_video_N_Out represents the output volume of the video file, and size_video_N_Out = size_video_N / size_Total*OutputVideo_size. It should be noted that in the embodiment of the present invention, the step of calculating the total volume is specifically as follows: first, the volume of each video file to be converted in the video file set to be converted is obtained respectively; then the sum of the volumes is calculated to obtain the total volume. In practical applications, if it is assumed that the volumes of each video file in the video files to be converted are size_video_1, size_video_2, size_video_3,..., size_video_N respectively, then the total volume size_Total = size_video_1 + size_video_2 +... + size_video_N.

[0038] Further, calculate the compression ratio Compress_ratio according to the total volume size_Total and the preset total volume OutputVideo_size of the video output file. Understandably, Compress_ratio = OutputVideo_size / size_Total; calculate the GOP value, the number of B frames, and the video frame rate in the encoding parameters corresponding to the current video file to be converted according to the compression ratio, the GOP value, the number of B frames, and the video frame rate. Specifically, calculate the ratio between the GOP value and the compression ratio to obtain the GOP value in the encoding parameters corresponding to the current video file to be converted; calculate the ratio between the number of B frames and the compression ratio to obtain the number of B frames in the encoding parameters corresponding to the current video file to be converted; calculate the ratio between the video frame rate and the compression ratio to obtain the video frame rate in the encoding parameters corresponding to the current video file to be converted. In practical applications, if it is assumed that the GOP value, the number of B frames, and the video frame rate in the current video file to be converted are video_N_GOP, video_N_BFrameNum, and video_N_Fps respectively, and the GOP value, the number of B frames, and the video frame rate in the encoding parameters are video_N_GOP_Out, video_N_BFrameNum_Out, and video_N_Fps_Out respectively, understandably, calculate the GOP value, the number of B frames, and the video frame rate in the encoding parameters as shown in formulas (1) to (3).

[0039] video_N_GOP_Out = video_N_GOP / Compress_ratio (1)

[0040] video_N_BFrameNum_Out = video_N_BFrameNum / Compress_ratio (2)

[0041] video_N_Fps_Out = video_N_Fps / Compress_ratio (3)

[0042] It should also be noted that in the embodiments of the present invention, since the preset total volume of the video output file is considered when calculating the encoding parameters, it can be ensured that the video output file meets the user's volume requirements for the video file.

[0043] S120. Adjust the video compression information according to the encoding parameters, and perform encoding conversion on the current video file to be converted according to the adjusted video compression information to obtain a video output file.

[0044] In an embodiment of the present invention, after calculating the encoding parameters corresponding to the current video file to be converted, the video compression information is adjusted according to the encoding parameters. Specifically, the video bit rate, GOP value, number of B frames, and video frame rate in the video compression information are replaced with the video bit rate, GOP value, number of B frames, and video frame rate in the encoding parameters to adjust the video compression information, and encoding conversion is performed on the current video file to be converted according to the adjusted video compression information to obtain a video output file, thus avoiding the user from manually setting encoding parameters, saving manpower, and improving the efficiency and accuracy of video conversion. It should be noted that in an embodiment of the present invention, the video compression information further includes information such as video width and video height; the video conversion software includes an encoder, and the encoding parameters are parameters set for the encoder.

[0045] S130. Select the next video file to be converted from the set of video files to be converted, and use the next video file to be converted as the current video file to be converted, and return to execute the step of obtaining video compression information from the current video file to be converted until all the video files to be converted in the set of video files to be converted are converted.

[0046] In an embodiment of the present invention, after performing encoding conversion on the current video file to be converted to obtain a video output file, the next video file to be converted is selected from the set of video files to be converted, and the next video file to be converted is used as the current video file to be converted. In practical applications, that is, the second video file to be converted is selected as the current video file to be converted, and the step of obtaining video compression information from the current video file to be converted is returned to execute until all the video files to be converted in the set of video files to be converted are converted to complete the encoding conversion of the set of video files to be converted.
