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...

Abstract

The invention discloses a method and a system for carrying out dolby transcoding on AV (Audio / Video). The method comprises the steps of obtaining the AV needing to be subjected to the dolby transcoding by a control center, splitting the AV by the control center, and obtaining an audio and a video; indicating and monitoring an operation for carrying out video transcoding on the video in a corresponding format and an operation for carrying out the dolby transcoding on the audio in a corresponding format by the control center, saving a generated audio file and a generated video file after the situation that the transcoding is completed is monitored, simultaneously executing dolby compositing on the audio file and the video file which are generated after the transcoding is completed, and outputting a dolby AV file. According to the method and the system, disclosed by the invention, the problems in the prior art that the dolby transcoding can be carried out by enabling the audio in the AV file to be independent from the AV file, the independent transcoding efficiency is low, and the requirement on transcoding processing of a large number of AV files cannot be met can be solved.

Description

technical field [0001] The present application relates to the field of video transcoding, and more specifically, relates to a method and system for performing Dolby transcoding on audio and video. Background technique [0002] With the rapid development of information technology, the form of expression and transmission of information has changed: from the traditional text (such as: books, newspapers) and audio (such as: radio), and then transformed into a vivid and more expressive Video format with a lot of information. Today's TV and the Internet present and share rich and comprehensive resources such as various film and television programs, news, advertisements, chats, education, and games in the form of video, so that video has become an irreplaceable and important tool for people to learn, socialize, and entertain. Way. [0003] At present, many Dolby channels have been launched, and the transcoding adopted is cloud transcoding, and in cloud transcoding, audio needs to...
