Generally, system playing terminals are all system-implemented, cannot be reconstructed, and have great limitation, so that two paths of audio and video streams cannot be processed simultaneously; in addition, the stability of hard decoding MediaCodec of the existing platforms such as TV is poor, and the system player is preferentially supported, but the system player does not support on-line plug-in audio track and does not support cross-platform application. The playing terminal provided by the specification can process the original sound slice source and simultaneously use the other path to process the audio stream; the sound and picture synchronization effect is realized by keeping the two paths of playing time stamps synchronous; the method can flexibly adapt to different languages, and meets the requirement of a user on the video of the target audio; the complexity of background operation is reduced, and the storage pressure of the background is greatly reduced.
As shown in fig. 1, a schematic diagram of an implementation environment provided by the embodiments of the present description is shown. The implementation environment includes: a server 02 and a terminal 01 which communicates information with the server 02.
Terminal 01 may be a mobile phone, a tablet, a laptop portable acquirer, a PAD or desktop acquirer, etc. A client runs in the terminal 01, and the client can be any client with video information acquisition and output; for example, the client operating in the terminal 01 may be a video playing client, a browser, an instant messaging client, a shopping client, and the like. The server 02 may be a server, a server cluster composed of a plurality of servers, or a cloud acquisition service center. The server 02 establishes a communication connection with the terminal 01 through a network.
Specifically, an embodiment of the present specification provides a video information obtaining method, as shown in fig. 2, the method includes:
s202, target video request information is obtained, wherein the target video request information comprises source video request information and target audio request information, and the target audio request information comprises target language request information;
in this embodiment, if the method is applied to a scene where a playing terminal plays videos, when a user requests a video in a certain language, the playing terminal generates a corresponding target video request message. The target video comprises video resources selected by a user and audio resources matched and fused with the video resources; specifically, the source video request information corresponds to a video resource selected by a user; the target audio request information corresponds to an audio resource which can be matched and fused with the source video, and the target language request information corresponds to the language of the audio resource.
S204, starting a first sub thread so that the first sub thread can send the source video request information and obtain a source video data stream conveniently;
s206, starting a second sub thread so that the second sub thread can send the source video request information and the target audio request information and obtain a target audio data stream; the target audio data stream is uniquely determined according to the source video request information and the target language request information; the starting time difference between the first sub thread and the second sub thread is smaller than a preset time threshold;
the first sub thread and the second sub thread in this embodiment are threads initiated by a playing terminal, and the playing terminal may include a first player and a second player; in particular, the first player may be a system player and the second player may be a self-developed player. Accordingly, the first sub-thread in this embodiment may be a thread initiated by the first player, and the second sub-thread may be a thread initiated by the second player.
In this embodiment, in one line, the system player sends the source video request information to the background media server, and after receiving the source video request information, the background media server finds a corresponding source video data stream according to the source video request information, and further returns the source video data stream to the playing terminal. The target audio data stream is a target audio matched with the source video data stream, so that the request content of the source video request information is required in the process of determining the target audio data stream. Correspondingly, in another line, the self-research player sends the source video request information and the target audio request information to the background media server, and the background media server finds the corresponding target audio after receiving the source video request information and the target audio request information, and further returns the target audio to the playing terminal.
It should be noted that, if the preset time threshold is 500ms close to 0, the starting time difference between the first sub-thread and the second sub-thread is less than 500ms, and the first sub-thread and the second sub-thread can almost achieve the effect of simultaneously acquiring a source video data stream and a target video data stream, so that the efficiency of acquiring a target video can be improved; if the starting time difference between the first sub-thread and the second sub-thread is 0, the first sub-thread and the second sub-thread are executed simultaneously, so that two paths of request information are processed simultaneously, the processing efficiency is improved, and the pressures of background transcoding and storage are reduced.
In a possible embodiment, the method may further include:
s203, sending target video request information to obtain video associated information; the video associated information comprises a source video storage address and a target audio storage address;
in this embodiment, the source video storage address is used to represent a storage location of the source video data stream in the background media server; the target audio storage address is used for representing the storage position of the target audio in the background media server.
Specifically, a video information server acquires target video request information from a playing terminal, and further obtains video associated information according to the target video request information; the video information server further authenticates the target video request information to determine the legality or anti-counterfeiting property of the target video request information; in detail:
s1a, performing security verification on the target video request information;
and S1b, when the verification result of the target video request information is legal request information, acquiring the video associated information.
The performing security verification on the target video request information may include:
s2a, extracting public key encryption information from the target video request information;
s2b, obtaining plaintext information obtained by decrypting the public key encrypted information through a private key;
and S2c, when the plaintext information obtained by decryption is legal information, the target video request information is legal request information.
In this embodiment, the target video request information may be subjected to validity check in a key verification manner; specifically, the information encrypted by the public key is extracted from the target video request information, the encrypted information is decrypted by a private key of the server side to obtain plaintext information, and the target video request information can be considered as legal request information under the condition that the plaintext information obtained by decryption conforms to the program verification logic of the server.
Giving an example for legitimacy: for example, a certain logic exists between the server and the client, the client encrypts a number and sends the encrypted number to the server, the server decrypts the encrypted information to obtain plaintext information of the number, if the number is verified to belong to a preset certain interval, the logic between the server and the client is considered to be satisfied, and the request information corresponding to the number is legal.
Further, the step S204 of sending the source video request information and acquiring a source video data stream may include:
sending the source video request information and acquiring a source video data stream obtained according to the source video request information and the source video storage address;
in this embodiment, after receiving the source video request information, the background media server finds the source video data stream according to the source video request information and the source video storage address, and further returns the source video data stream to the playing terminal.
Further, the step S206 of sending the source video request information and the target audio request information and obtaining the target audio data stream may include:
and sending the source video request information and the target audio request information, and acquiring a target audio data stream obtained according to the source video request information, the target audio request information and the target audio storage address.
Similarly, in this embodiment, after receiving the source video request information and the target audio request information, the background media server finds the target audio data stream according to the source video request information, the target audio request information, and the target audio storage address, and further returns the target audio data stream to the play terminal.
In a specific embodiment, the step S203 of sending the target video request information to obtain the video related information, as shown in fig. 3, includes:
s402, sending the target video request information to obtain intermediate associated information, wherein the intermediate associated information comprises a source video storage address, an audio language supported by a source video data stream and a storage address of an audio language supported by the source video data stream;
s404, determining a target audio storage address corresponding to the target audio request information from the storage addresses of the audio languages supported by the source video data stream;
s406, obtaining the video associated information according to the source video storage address and the target audio storage address.
In this embodiment, the audio language supported by the source video data stream may be understood as an audio language that can be rendered with the source video data stream to generate a new video data stream. And the storage address of the audio language is used for representing the storage position of the audio language in the background media server.
Specifically, the target audio corresponding to the user's intention in the target audio request information is used to find the storage location of the target audio at the background media server by determining the storage address of the target audio. And meanwhile, according to the source video storage address, the storage position of the source video data stream at a background media server end is found.
In a specific implementation manner, the step S404 determines a target audio storage address corresponding to the target audio request information, as shown in fig. 4, and previously includes:
s602, acquiring the number of audio languages supported by the source video data stream;
s604, when the number of the audio languages supported by the source video data stream is multiple, judging whether the audio languages contain a target language corresponding to the target language request information;
and S606, when the language comprises a target language corresponding to the target language request information, determining a target audio storage address.
In this embodiment, the language type supported by the source video data stream is detected to obtain the language corresponding to the target audio request information, so as to determine the target audio storage address. The embodiment can ensure the existence of the language supported by the source video data stream, thereby ensuring that the target video is finally obtained and meeting the requirements of users.
It should be noted that in this embodiment, after the video associated information is obtained, a source video storage address is extracted from the video associated information, and when a system player initiates a video request to a background media server, a corresponding source video data stream is obtained according to the source video storage address. And when a system player initiates a video request to the background media server, if the source video data stream is determined to support multiple languages and a target audio storage address is extracted, the self-research player requests the background media server for the audio data of the target audio.
And S208, generating a target video in real time according to the source video data stream and the target audio data stream.
In this embodiment, after obtaining the languages of the source video data stream and the target audio, the playing terminal performs rendering processing on the source video data stream and the target audio to obtain the target video, as shown in an interface display diagram shown in fig. 5.
In a possible implementation, the step S208 generates the target video from the source video data stream and the target audio data stream in real time, as shown in fig. 6, which may include:
s802, acquiring a first playing time stamp and a second playing time stamp; the first playing time stamp is the playing time stamp of the source video data stream, and the second playing time stamp is the playing time stamp of the target audio data stream;
s804, adjusting the second playing time stamp to enable the second playing time stamp to be synchronous with the first playing time stamp;
and S806, obtaining the target video according to the source video data stream, the first playing time stamp, the target audio data stream and the second playing time stamp.
In this embodiment, when the data received in the path of the source video data stream and the data received in the path of the target audio data are both buffered to a state in which the data can be played, the playing terminal may start playing the target video. Specifically, the second playing timestamp is adjusted to synchronize the second playing timestamp with the first playing timestamp, which can be understood as that the playing timestamp of the system player is provided for the self-developed player in the packaging layer of the playing terminal, so that synchronization of two paths of data streams playing sound and pictures is realized, and a normal playing function is realized.
It should be noted that the source video data stream corresponding to the source video request information includes original video image information and initial language information; the initial language information may be a language used for making a file corresponding to the source video data stream, such as a language of a large hollywood english language; or the language supported by the local system, such as the Chinese language supported by the continental version of apple mobile phone. And when the language selection is not made by the user, defaulting that the target audio is the language supported by the local system.
The technical scheme for acquiring the video information provided by the specification can be compatible with the defect that a system player does not support a plug-in audio track; the user can flexibly select an intentional language or automatically adapt to a local language for playing; background processing and storage of a large number of videos are not needed, and the pressure of a background server is greatly reduced; the user requirements of different languages are met, the user experience is improved, and the user viscosity of the corresponding terminal equipment is improved.
