It should be noted that, in this embodiment, each time a new client is added to the audio/video file sharing system, the server in the system automatically configures a corresponding and unique client identifier code for the new client.
In the audio and video file sharing system, when the system is in a multi-user chat mode, one or more of the clients can initiate real-time audio and video file sharing, so that the audio and video files to be shared are transmitted to other clients and simultaneously played in the other clients in real time. In this embodiment, a client initiating audio and video file sharing is used as a sending end, and a client receiving the audio and video file sharing is used as a receiving end. Specifically, the audio and video file sharing process mainly comprises a sharing preparation phase and a sharing implementation phase.
In the sharing preparation stage, firstly, a sending end generates a corresponding file sharing request according to an identification code of the sending end and the file type of the audio/video file to be shared, and sends the file sharing request to a server end; after receiving the file sharing request, the server analyzes the file sharing request, obtains a sender identification code and a file type of an audio and video file to be shared, generates a corresponding file sharing instruction according to the sender identification code and the file type, and sends the file sharing instruction to a corresponding receiving end for receiving the audio and video file sharing; meanwhile, the server generates a corresponding file identification code according to the sending end identification code and the file type obtained by analysis, and returns the file identification code to the sending end; after receiving a file sharing instruction sent by a server, the receiving end analyzes the file sharing instruction to obtain a sending end identification code and a file type of an audio and video file to be shared; and then, the receiving terminal generates a corresponding playing control according to the file type obtained by analysis, and configures a corresponding control identification code for the playing control according to the file type and the sending terminal identification code obtained by analysis.
In the sharing implementation stage, the sending end configures the file identification code returned by the server end to the audio and video file to be shared, and sends the configured audio and video file to the server end frame by frame; the server side forwards the audio and video frames to a corresponding receiving end when receiving the audio and video frames sent by the sending end; and the receiving terminal analyzes the audio and video frame when receiving the audio and video frame forwarded by the server terminal, so as to obtain a file identification code in the audio and video frame, and sends the audio and video frame to a playing control corresponding to the control identification code corresponding to the file identification code for displaying.
According to the audio and video file sharing system provided by the embodiment of the invention, the unique corresponding playing control is allocated to the audio and video file to be shared in the multi-user chat mode, and when one frame of data of the audio and video file to be shared is received, the audio and video frame of data is sent to the playing control to be played, so that the real-time playing and sharing of the audio and video file in the multi-user chat process can be realized, the audio and video file can be played without waiting until the audio and video file is downloaded completely, the timeliness of the audio and video file sharing in the multi-user chat mode is improved, and the user experience is further improved.
The embodiment of the invention also provides an audio and video file sharing method.
Referring to fig. 2, it is a flowchart of a preferred embodiment of the audio/video file sharing method provided in the present invention, including steps S21 to S23, specifically:
s21, when the mobile terminal is in a multi-person chat mode, analyzing the received file sharing instruction to obtain the identification code of the sending terminal and the file type of the audio/video file to be shared; the identification code of the transmitting end is the identification code of the transmitting end sharing the audio and video file.
It should be noted that the embodiment of the present invention is executed by the receiving end in the audio/video file sharing system. The embodiment of the invention is suitable for a multi-person chat mode with multi-end interaction (such as two-person video chat, three-person or more-than-three video conference and the like).
In the embodiment, in a multi-user chat mode, a sending end initiates audio and video file sharing by sending a file sharing request to a server end; when receiving a file sharing request sent by a sending end, a server analyzes the file sharing request so as to obtain a sending end identification code and a file type of an audio and video file to be shared, and generates a corresponding file sharing instruction according to the sending end identification code and the file type; then, the server side sends the file sharing instruction to one or more receiving ends, so that each receiving end is ready for receiving audio and video file sharing; after receiving a file sharing instruction sent by a server, a receiving end analyzes and obtains the identification code of the sending end and the file type of the audio and video file to be shared from the file sharing instruction, and prepares for correspondingly receiving the audio and video file to be shared according to the identification code of the sending end and the file type.
S22, creating a corresponding playing control according to the file type, and generating a control identification code of the playing control according to the sender identification code and the file type.
In this embodiment, after the receiving end obtains the identification code of the transmitting end and the file type of the audio/video file to be shared by analysis, a preparation for correspondingly receiving the audio/video file to be shared is made according to the identification code of the transmitting end and the file type. Specifically, a corresponding playing control is created according to the file type to be used for playing the audio/video file to be shared, and then a control identification code of the playing control is generated according to the identification code of the transmitting terminal and the file type to be used for distinguishing the audio/video files from different transmitting terminals and different types.
In another preferred embodiment, the file type is represented by a file type identification code, and step S22 may further include sub-steps S2201 to S2202:
s2201, creating a corresponding playing control according to the file type identification code;
s2202, setting a result obtained by adding the sending end identification code and the file type identification code as the control identification code of the playing control.
In this embodiment, the file type is represented by a file type identifier, and the file type identifier is generated by the server and each client in advance. Specifically, a corresponding relation table of the file type information and the file type identification code is stored in the server; in the process of initiating audio and video file sharing, a sending end sends a file sharing request containing file type information of an audio and video file to be shared to the server end, so that the server end queries the corresponding relation table according to the file type information in the file sharing request, and a file type identification code corresponding to the audio and video file to be shared is determined; then, the server side sends a file sharing instruction containing the file type identification code to a receiving side; after receiving the file sharing instruction, the receiving end reads and obtains the identification code of the sending end and the identification code of the file type from the file sharing instruction, and configures a corresponding control identification code for the playing control according to the identification code of the file type and the identification code of the sending end after a corresponding playing control is established according to the identification code of the file type.
More preferably, the server configures a synchronization source identifier SSRC for each client as the client identifier code; the server and each client agree to use a positive integer n as a file type identification code, wherein different n values represent different file types.
In this embodiment, after obtaining the sending-end identification code SSRC and the file type identification code n of the audio/video file to be shared according to the received file sharing instruction, the receiving end creates a corresponding play control according to the file type identification code n, and sets the sum of the sending-end identification code SSRC and the file type identification code n as the control identification code of the play control, so that the control identification code of the play control is set to SSRC + n.
For example, assuming that a sender id SSRC of a certain sender is 5580, a file type id n of an audio file agreed between a server and each client is 1, and a file type id n of a video file is 2, when the sender initiates video file sharing, a receiver creates a corresponding play control for the video file to be shared, and configures a control id with a value of 5582 (because 5580+2 is 5582) for the play control.
And S23, when an audio/video frame of the audio/video file is received, extracting a file identification code of the audio/video file from the audio/video frame, and sending the audio/video frame to the playing control corresponding to the control identification code corresponding to the file identification code for playing.
In this embodiment, the sending end sends the audio and video file to be shared to the server end in a frame form. And each audio and video frame comprises a file identification code of the audio and video file to be shared. And the server forwards the audio and video frames to the corresponding receiving end when receiving the audio and video frames sent by the sending end. When the receiving end receives the audio and video frames forwarded by the server, the file identification code of the audio and video file to be shared is extracted from the audio and video frames, each local playing control is inquired according to the file identification code, whether the playing control with the playing identification code consistent with the file identification code exists or not is judged, if yes, the received audio and video frames are sent to the playing control to be played, and if not, the received audio and video frames are discarded, and/or corresponding error prompt information is generated.
In another preferred embodiment, the file identification code is generated by the server according to the sender identification code and the file type in the file sharing request when the server receives the file sharing request sent by the sender; before step S23 is executed, the method further includes:
and generating a reference file identification code according to the sender identification code and the file type in the file sharing instruction.
The above step S23 may further include sub-steps S2301 to S2302:
s2301, extracting the file identification code of the audio and video file from the audio and video frame;
and S2302, when the file identification code is judged to be the same as the reference file identification code, sending the audio and video frame to the playing control corresponding to the control identification code corresponding to the reference file identification code for playing.
In this embodiment, after receiving a file sharing instruction, a receiving end generates a corresponding reference file identification code according to a sender identification code and a file type identification code in the file sharing instruction, so as to verify a sender and a file type corresponding to an audio/video frame received at a later stage. Specifically, after receiving an audio/video frame, a receiving end extracts a corresponding file identification code from the audio/video frame, compares the file identification code with the reference file identification code, and determines whether the file identification code is consistent with the reference file identification code, if so, it indicates that a transmitting end transmitting the audio/video frame is a transmitting end initiating audio/video file sharing in the early stage, and the file type of the audio/video frame is a file type to be shared in the early stage, so that the audio/video frame is transmitted to a corresponding playing control for playing, and if not, it indicates that the transmitting end corresponding to the audio/video frame is wrong or the corresponding file type is wrong, so that the audio/video frame is discarded, and/or corresponding error prompt information is generated for a user to perform corresponding processing.
More preferably, the server configures a synchronization source identifier SSRC for each client as the client identifier code; the server and each client agree to use a positive integer n as a file type identification code, wherein different n values represent different file types.
In this embodiment, when receiving a file sharing request sent by a sender, a server generates a file identification code SSRC1 (where SSRC1 is SSRC + n) according to a sender identification code SSRC and a file type identification code n in the file sharing request, and returns the file identification code SSRC1 to the sender; after receiving a file sharing instruction sent by a server, a receiving end generates a reference file identification code SSRC2 according to a sending end identification code SSRC and a file type identification code n in the file sharing instruction (wherein SSRC2 is SSRC + n); in the file sharing stage, after the transmitting end configures the file identification code SSRC1 to an audio/video file to be shared, the audio/video frame of the audio/video file is transmitted to the receiving end through the service end, the receiving end extracts the file identification code SSRC1 from the received audio/video frame, compares the file identification code SSRC1 with the reference file identification code SSRC2, judges whether the audio/video frame is consistent with the reference file identification code SSRC2, if so, the audio/video frame is considered to be the audio/video frame which is transmitted by the transmitting end which initiates the audio/video sharing in advance and belongs to the file type to be shared, the audio/video frame is the audio/video frame in the audio/video file to be shared in advance, therefore, the audio/video frame is transmitted to the playing control corresponding to the control identification code which is consistent with the reference file identification code SSRC2 to play, if not, the audio/video frame is considered not to, therefore, the audio and video frames are discarded, and/or corresponding error prompt information is generated to be used for corresponding processing of a user.
In another preferred embodiment, the playing control includes a display window, and when the step S23 is executed, the method further includes:
and acquiring the user information of the sending end according to the identification code of the sending end, and sending the user information to a display window of the playing control for displaying.
In this embodiment, the display window of the play control is used to display the audio/video file received by the receiving end. After extracting the identification code of the sending end from the file sharing instruction, the receiving end acquires the user information of the sending end corresponding to the identification code of the sending end from the server according to the identification code of the sending end, and sends the user information to the display window for displaying.
In any of the above embodiments, the file types include an audio file type and a video file type; and the audio and video file is transmitted in a data stream mode.
In any of the above embodiments, the file sharing instruction is sent by the server when receiving the file sharing request sent by the sender.
In any of the above embodiments, the file type may be an audio file type, a video file type, a document file type, and the like. When the file type is an audio file type, the playing control created by the receiving end may be a music player or the like. When the file type is a video file type, the playing control created by the receiving end may be a video player or the like.
The audio and video file can be transmitted in a data stream form, and the file identification code is the identification code of the data stream allocated by the server for the audio and video file to be shared. It should be further explained that the data stream of the audio/video file and the data stream of the real-time video shot by the camera in the multi-person chat mode can be transmitted independently or can be combined into a whole for total data stream transmission.
According to the audio and video file sharing method provided by the embodiment of the invention, the unique corresponding playing control is allocated to the audio and video file to be shared in the multi-user chat mode, and when one frame of data of the audio and video file to be shared is received, the audio and video frame of data is sent to the playing control to be played, so that the real-time playing and sharing of the audio and video file in the multi-user chat process can be realized, and the audio and video file can be played without waiting until the audio and video file is downloaded completely, so that the timeliness of the audio and video file sharing in the multi-user chat mode is improved, and the user experience is further improved.
Fig. 3 is a schematic diagram of a display effect of a preferred embodiment of the audio/video file sharing method provided by the present invention. The following describes in detail a specific working process of the audio/video file sharing method provided by the embodiment of the present invention:
as shown in fig. 3(a), in a video conference, three clients are performing a video call, including a client a, a client B, and a client C, assuming that the client a is a sending terminal, the client B and the client C are receiving terminals, and the server configures a synchronization source identifier SSRC for each client as a client identifier, and the server and each client agree to use a positive integer n as a file type identifier.
A sending end A sends a file sharing request to a server end by clicking a button or dragging an audio/video file into a video conference window; when a server receives a file sharing request sent by a sender A, analyzing the file sharing request to obtain a sender identification code SSRC of the sender A and a file type identification code n of an audio/video file to be shared, generating a file identification code SSRC1(SSRC1 is SSRC + n) according to the sender identification code SSRC and the file type identification code n, and returning the file identification code SSRC1 to the sender A, wherein the sender identification code SSRC of the sender A is assumed to be 5590, the file type identification code n is assumed to be 2, and the file type is a video file, the file identification code SSRC1 is assumed to be 5592; meanwhile, the server generates a corresponding file sharing instruction according to the sending end identification code SSRC and the file type identification code n and sends the file sharing instruction to the receiving end B and the receiving end C, which is described below by taking the receiving end C as an example, and the receiving end B is the same as the receiving end B.
After receiving a file sharing instruction sent by a server, a receiving terminal C analyzes and obtains a sending terminal identification code SSRC of a sending terminal a which is 5590 and a file type identification code n of an audio/video file to be shared which is 2 from the file sharing instruction; because n is 2, the video file is represented, the playing control created by the receiving end C for the shared video file is a video player, and the control identification code of the video player is 5592; meanwhile, the receiving end C generates the reference file identification code SSRC2 according to the sender identification code SSRC and the file type identification code n (SSRC2 ═ SSRC + n), and then the reference file identification code SSRC2 is 5592.
The sending end A configures the file identification code SSRC1 returned by the server to the video file to be shared, and sends the data stream of the video file to the receiving end C through the server; the receiving terminal C extracts and obtains a file identification code SSRC1 ═ 5592 from the data stream, compares the file identification code SSRC1 ═ 5592 with a reference file identification code SSRC2, and sends the data stream to a video player with a control identification code 5592 for playing if the SSRC2 ═ 5592 is consistent with the SSRC 1; meanwhile, the receiving terminal C determines the user information of the transmitting terminal a according to the transmitting terminal identification code SSRC ═ 5590 of the transmitting terminal a obtained from the file sharing instruction, and sends the user information to the window of the video player for display. On the other hand, if the receiving end C cannot find the reference file identification code that is consistent with the file identification code SSRC 1-5592, the data stream is discarded, and/or corresponding error prompt information is generated for the user to perform corresponding processing.
As shown in fig. 3(b) and 3(c), there are two playing modes of the shared audio/video file: fig. 3(b) shows a manner in which the transmitting end a transmits a data stream of a shared audio/video file as an individual data stream, and the receiving end C creates an individual display window for the data stream to play the shared audio/video file, in which the shared audio/video file is added to the video conference as a client, and a picture of the audio/video file is displayed in a manner of displaying a video conference picture of the client; the mode shown in fig. 3(C) is that the transmitting end a merges the data stream of the shared audio/video file and the data stream of the video conference of the transmitting end a itself into one data stream to be transmitted, instead of being transmitted as a separate data stream, the receiving end C creates a sub-window in the video window of the receiving end C itself to play the shared audio/video file when receiving the data stream, and the shared audio/video file is displayed together with the video window of the receiving end C itself in the form of the sub-window.
When the shared audio/video file is played, the playing window is closed, and the video conference is restored to the state shown in fig. 3 (a).
Because the shared audio and video file is transmitted in the form of data stream, the receiving end does not need to download the complete audio and video file, but directly processes the data stream received each time to play and display, if the receiving end adopts the mode as shown in fig. 3(b), and has the data stream storage function, whether to store the file can be selected after the playing of the shared audio and video file is finished, and because all the data streams of the audio and video file are transmitted when the playing is finished, the operation of storing the file is finished locally, and the transmission of the file does not need to be waited again, therefore, the timeliness of the sharing of the audio and video file is improved, and the user experience is improved.
If the transmitting end performs operations such as playing position selection and the like when sharing the audio and video files, and skips a certain part of audio and video, the data of the audio and video files can be partially lost, and at the moment, the receiving end cannot receive the complete audio and video files, the function of storing the files is not meaningful, and from the perspective of user experience, the transmitting end needs to send reminding information before performing operations such as playing position selection and the like, so as to avoid the receiving end from selecting and storing the files.
