[0029] Embodiment 1

[0030] Figure 1This is a flow chart of an audio playback method provided by the first embodiment of the present disclosure. The present embodiment is applicable to the scenario of audio playback, especially the situation of switching audio data during video playback. The method can be executed by an audio playback device configured on the client, which can be implemented in the form of software and / or hardware, and can be configured in an electronic device, such as a mobile terminal or a server device.

[0031] like Figure 1 As shown, the audio playback method provided in this embodiment includes:

[0032] S110. During the current audio and video data playback process, when an audio data switching instruction is obtained, a request is made to a server for target audio data associated with the audio data switching instruction.

[0033] The audio playback method in this embodiment is applicable to various video application platforms, and the video data and audio data in the current audio and video data being played are two independent sets of data. During the playback of the video data and the audio data, the playback of the audio and video data can be synchronized by receiving the timestamp information of the corresponding data of the video data and the audio data, or the key frame information of the audio data and / or the video data. Among them, the key frame is the most important frame in the compression coding of the audio and video data, such as the I frame in the compression coding of the video data.

[0034] During the current audio and video data playback, when the audio data switching instruction is obtained, the client will send a request to the server to obtain the target audio data associated with the audio data switching instruction. The target audio data is the target object of the audio switching, and the initial audio data in the current audio and video is switched to the target audio data. Specifically, in the process of obtaining the target audio data, a connection channel is established with the server through the data acquisition link of the target audio data provided by the server; then, the target audio data is obtained through the connection channel and cached, and the playback is performed after the playback time is determined. Further, the target audio data and the initial audio data are data of different audio contents associated with the video data in the current audio and video data. In some scenarios, the initial audio data and the target audio data can be dubbing audio data of different languages ​​matching the same video data. For example, a movie video contains dubbing audio data in different languages ​​such as Chinese, English, French and Japanese that match it. The audience of the movie can switch audio data of any language while watching the movie. Alternatively, some cartoons have Mandarin versions and dialect versions of dubbing, and the audience can also choose different versions of audio data to play, and switch different versions of dubbing audio data during the playback process.

[0035] S120: Determine a playback time of the target audio data according to key frame information of the video data in the current audio and video data.

[0036] When performing audio and video synchronization, the video can usually be synchronized to the audio, that is, the video is synchronized based on the playback speed of the audio. The audio can also be synchronized to the video, that is, the audio is synchronized based on the playback speed of the video. Alternatively, the video and audio can be synchronized to an external clock, and an external clock is selected as a reference, and the playback speeds of the video and audio are both based on the clock. In this embodiment, considering the instability of audio switching, the synchronization strategy of synchronizing audio to video is preferred.

[0037] Specifically, in the cached but unplayed video data, determine the video key frame that is adjacent to the video image frame corresponding to the moment when the audio data switching instruction is obtained and has not been played, that is, according to the time sequence of each video image frame, the first video key frame after the video image frame corresponding to the moment when the audio data switching instruction is obtained; then, use the video playback time corresponding to the video key frame as the playback time of the target audio data. Thus, after the user's audio data switching instruction is issued, a response can be made quickly to perform the audio switching operation.

[0038] S130: At the playing time, switch the initial audio data in the current audio and video data to the target audio data and play the target audio data.

[0039] At the determined target audio data playback time, the target audio data is played to replace the initial audio data. While consuming the new target audio data, the cached data of the initial audio data after the playback time in the audio data cache area needs to be cleared to prevent the initial audio data from continuing to play after the playback time. This achieves the playback connection between the target audio data and the initial audio data. During this process, the playback of the video data does not stop, so there will be no black screen or freeze problems.

[0040] The technical solution of the disclosed embodiment can be achieved by, during the playback of the current audio and video data, when an audio data switching instruction is obtained, requesting the target audio data associated with the audio data switching instruction from the server; determining the playback time of the target audio data according to the key frame information of the video data in the current audio and video data; and switching the initial audio data in the current audio and video data to the target audio data at the playback time and playing it. The audio data and video data in the audio and video data to be played are independent of each other, so that the two independent data are played synchronously according to the key frame information of the video data. The technical solution of the disclosed embodiment solves the problem in the prior art that when switching audio, it is necessary to switch a video containing another different audio, resulting in excessive traffic consumption and unsmooth video playback connection. It can achieve the ability to switch only audio data during the video playback process, without generating redundant video content downloads, and make the video play smoothly, avoiding the black screen and freeze phenomenon of the video playback interface.

[0041] Embodiment 2

[0042] The embodiments of the present disclosure can be combined with the various optional solutions in the audio playback method provided in the above embodiments. The audio playback method provided in this embodiment further describes the process from the current audio and video data playback to the audio data playback.

[0043] Figure 2 This is a flow chart of an audio playback method provided by Embodiment 2 of the present disclosure. Figure 2 As shown, the audio playback method provided in this embodiment includes:

[0044] S210. According to the audio and video data acquisition instruction of the user, request a data acquisition link of video data and at least one corresponding audio data associated with the audio and video data acquisition instruction from the server.

[0045] The audio playback method in this embodiment is applicable to various video application platforms, and the video data and audio data in the current audio and video data being played are two independent sets of data. That is to say, in the process of producing audio and video data, audio data and video data are produced separately, and multiple audio contents are produced corresponding to one video content, and each audio content is different. For example, a movie video has corresponding dubbing audio data in different languages ​​such as Chinese, English, French and Japanese.

[0046] When a user selects a video to watch on a video application platform, he can search for the video he wants to watch on the platform, or watch the video recommended by the video application platform. When the user determines the video to watch, he sends an audio and video data acquisition instruction to the video application client, and the video application client requests the corresponding audio data and video data resources from the server according to the audio and video data acquisition instruction. The server will feedback the corresponding audio and video data resource link, including a video data acquisition link and at least one corresponding audio data data acquisition link.

[0047] In the past, audio and video data were fused together with time domain video data. If a film or TV work has different dubbing versions, the video files with the same video content and different language audios are stored on the server side, which results in high video production and storage costs for the server side. However, through the technical solution of this embodiment, video data and audio data can be stored separately. When playing the video, the corresponding video data and audio data groups can be played synchronously according to the user's playback requirements, which greatly reduces the video production and storage costs of the server side and is more friendly to the operation of the server side.

[0048] S220. According to the user's initial audio data determination instruction, determine the initial audio data in the at least one audio data, and obtain the video data and the initial audio data as the current audio and video data through the corresponding data acquisition link and play them.

[0049] The user needs to select one audio data as the initial audio data from one or more audio resources provided by the server. After the user determines the initial audio data, an initial audio data determination instruction is sent to the client. The client determines the initial audio data from at least one audio data according to the obtained initial audio data determination instruction, and establishes an audio and video data transmission link with the server based on the corresponding data acquisition link to obtain the video data and the initial audio data as the current audio and video data and play them.

[0050] S230: During the current audio and video data playback process, when an audio data switching instruction is obtained, request the server for target audio data associated with the audio data switching instruction.

[0051] In the currently played audio and video data, if there is more than one audio data corresponding to the video data, the user can issue an audio data switching instruction during the current audio and video data playback to switch to different audio data. For example, if the initial audio data is the English dubbing audio of the video data, and the user wants to switch to the Chinese dubbing audio, then the Chinese dubbing audio data is the target audio data.

[0052] S240: Determine a playback time of the target audio data according to key frame information of the video data in the current audio and video data.

[0053] In this embodiment, the synchronization strategy of synchronizing audio to video is preferred. In the cached but unplayed video data, the video key frame adjacent to the video image frame corresponding to the moment when the audio data switching instruction is obtained and not played is determined; then, the video playing time corresponding to the video key frame is used as the playing time of the target audio data. Therefore, after the user's audio data switching instruction is issued, a response can be made quickly to perform the audio switching operation.

[0054] S250: At the playing time, the initial audio data in the current audio and video data is switched to the target audio data and played.

[0055] The technical solution of the disclosed embodiment provides audio and video resources to users in a way that video data and audio data are independent of each other, and the corresponding audio data and video data are played synchronously according to the user's choice. In addition, during the current audio and video data playback process, when the audio data switching instruction is obtained, the target audio data associated with the audio data switching instruction is requested from the server; the playback time of the target audio data is determined according to the key frame information of the video data in the current audio and video data; at the playback time, the initial audio data in the current audio and video data is switched to the target audio data and played. It can be that the user does not need to pause the video during the video viewing process, and can switch different audio data. The technical solution of the disclosed embodiment solves the problem that the video containing another different audio needs to be switched when switching audio in the prior art, resulting in excessive traffic consumption and unsmooth video playback connection, and realizes that only audio data can be switched during the video playback process, and no redundant video content download will be generated, and the video is played smoothly, avoiding the black screen and freeze of the video playback interface, so that users have a better video consumption experience.

It realizes that only audio data can be switched during the video playback process, and no redundant video content download will be generated. The video is played smoothly, avoiding the black screen and freeze of the video playback interface.

[0061] In some optional implementations, the audio switching time positioning module 320 is specifically used to:

[0062] Determine, in the video data, a video key frame that is adjacent to the video image frame corresponding to the moment when the audio data switching instruction is obtained and has not been played;

[0072] According to the user's initial audio data determination instruction, the initial audio data is determined in the at least one audio data, and the video data and the initial audio data are acquired as the current audio and video data through the corresponding data acquisition link.

[0073] In some optional implementations, the initial audio data and the target audio data are dubbing audio data in different languages ​​matching the same video data.
