Embodiment 1
[0032] Such as figure 2 As shown, it is a method for performing Dolby transcoding on audio and video described in Embodiment 1 of the present application, the method comprising:
[0033] In step 101, a control center obtains the audio and video to be transcoded, and the control center splits the audio and video to obtain audio and video.
[0034] Specifically, when a video website performs a video transcoding task, it will transfer the video source stored in the video source server for transcoding processing. Under normal circumstances, the video website uses a cloud transcoding system, and users from all over the world can transfer video resources to Upload to the corresponding source server, and after transcoding, users in other regions can access the video website to watch or download the corresponding video through computer terminals, mobile terminals or TV terminals (the video here refers to audio and video) , further including the resolution, bit rate, video format, an...
Embodiment 2
[0043] Such as image 3 As shown, it is a method for Dolby transcoding of audio and video described in Embodiment 2 of the present application, the method comprising:
[0044] In step 201, a control center obtains the audio and video to be transcoded, and the control center splits the audio and video to obtain audio and video.
[0045] Step 202, for instructing and monitoring the video transcoding operation in the corresponding format according to the video bit rate corresponding to the Dolby bit rate for the video obtained by the acquisition and splitting unit through the control center, and through the audio transcoding machine Cooperate with the DP600 transcoding machine to complete the Dolby transcoding operation of the corresponding format for the audio obtained by the acquisition and splitting unit, and save the generated audio files and video files after the transcoding is completed, and complete the transcoding at the same time Perform Dolby synthesis on the generated...
Embodiment 3
[0049] The specific application of the method for carrying out Dolby transcoding to audio and video is described in detail below:
[0050] The background is: one existing audio and video (take the film source as an example) will be transcoded, that is, the film source A, where:
[0051] The resolution of source A is 848*480, the bit rate is 550kbps, and the format is MP4;
[0052] The above film sources will be played on TV terminals, mobile terminals, and computer terminals, and need to be transcoded into the ".flv" format transcoded by Dolby.
[0053] The specific steps are:
[0054] First, the control center receives the film source A, and splits the film source A to obtain audio and video.
[0055] Afterwards, the control center assigns the obtained video to the video transcoding machine for video transcoding. The video transcoding is performed according to the transcoding script preset in the control center, and at the same time through the cooperation of the audio tran...
