The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
The scheme of the embodiment of the application can be applied to scenes related to live broadcast interaction, such as network live broadcast, and is a live broadcast application scene schematic diagram shown according to an exemplary embodiment as shown in fig. 1, where fig. 1 includes a server serving as server-side equipment, and a smart phone, a tablet computer, and a personal computer serving as client-side equipment. The client device may also be an electronic device such as a PDA (Personal Digital Assistant), a multimedia player, and a wearable device.
The server device in fig. 1 provides live broadcast services to each client device, and a user may install a live broadcast client in the client device and obtain the live broadcast services through the live broadcast client. Typically, two types of users are involved in the live broadcast process, one type being the anchor user and the other type being the viewer user. The live broadcast client provides the live broadcast function when in the anchor mode, and provides the live broadcast watching function when in the audience mode. The anchor user can use the live broadcast function provided by the live broadcast client to carry out live video broadcast. For example, the live broadcast client can start a video shooting module of the intelligent device, acquire video data in real time through the video shooting module and send the video data to the server, the server broadcasts the received video data to the live broadcast clients of all audience users in the live broadcast room, and the audience users can watch live broadcast content of the anchor user by using a watching function provided by the live broadcast clients.
At present, in the same live broadcast room, if a viewer in the live broadcast room successfully robs a wheat, the viewer can become a second live broadcast after a first live broadcast stops broadcasting, and uploads video data to a video streaming server, and the live broadcast is carried out in the live broadcast room through the video streaming server. Since the second anchor waits for the first anchor to stop playing before uploading data, and a time interval exists between stop playing and start playing, the video stream displayed in the live broadcast room can be cut off.
In order to avoid the defect of cut-off of the video stream displayed in the live broadcast room when the anchor is replaced in the related art, the present application provides a video stream switching method, which can be applied to the live broadcast network architecture shown in fig. 1. The scheme provided by the present application is explained in detail below.
As shown in fig. 2, fig. 2 is a flowchart of a video stream switching method according to an exemplary embodiment, which can be applied in a live client.
When the live client is in a main broadcasting mode, the method comprises the following steps:
in step 201, sending the collected video data to other live broadcast clients in a live broadcast room, and displaying the video data;
in step 202, the off-air time information is obtained and sent to other live broadcast clients of the live broadcast room;
in step 203, when it is determined that the off-air time arrives according to the off-air time information, the uploading of the video data is stopped.
While the live client is in viewer mode, the method comprises:
in step 204, playing the video data of the current anchor;
in step 205, receiving the off-air time information;
in step 206, when the current audience is determined to be the next anycast according to the wheat sequence list, the mode is switched to the main broadcast mode.
In step 207, when it is determined that the current viewer is not the next anycast according to the wheat sequence list and the off-air time is reached according to the off-air time information, switching the video data of the current anycast into the video data of the next anycast according to the wheat sequence list for playing; wherein, the wheat sequence list records the anchor marks of different anchors according to the wheat turn-round sequence.
In this embodiment, the current anchor user can send the collected video data to a video streaming server (also referred to as a media server) through a live client, send the video data to other live clients of a live room through the video streaming server, and display the video data on the live client, and the other live clients can also play the video data of the current anchor. The video data is used for live broadcasting, and the video data can be acquired through the equipment where the live broadcasting client is located, or acquired through the camera equipment connected with the equipment where the live broadcasting client is located, without limitation. It can be understood that the current anchor will always send video data to other live clients in the live broadcast room before the anchor is not stopped, which is not described herein.
First, a live client in a main broadcast mode is introduced.
In order to avoid the situation that the video stream displayed in the live broadcast room has a cut-off state when the main broadcast is changed, the live broadcast client in the live broadcast mode can acquire the information of the off-air time and share the information of the off-air time to other live broadcast clients in the live broadcast room.
Wherein the stop time information is time information for instructing the current anchor to stop uploading the video data.
In an optional implementation manner, the stop time information may be a stop time, and the stopping uploading of the video data when the stop time is determined to arrive according to the stop time information includes: and when the stop-broadcasting time arrives, stopping uploading the video data.
The current anchor user can specify the stop time and stop uploading the video data when the stop time is reached. The specified time of the stop time may be a time when the live broadcast is ended, a time when the live broadcast is started, a certain time during the live broadcast, or the like. For example, the anchor user sets the stop time through the stop time setting control, the live client receives the setting instruction based on the stop time setting control to obtain the stop time, sends the stop time to other live clients in the live room, and stops uploading the video data when the stop time is reached.
As can be seen from the above embodiments, in the present embodiment, the time for stopping uploading the video data is determined by directly specifying the stop time, so that controllability of the stop time is achieved.
In another alternative implementation, the off-air time information may be a countdown time from the current time. When the stop-off time is determined to reach according to the stop-off time information, stopping uploading the video data, comprising: and stopping uploading the video data when the countdown is determined to be completed (countdown is finished) according to the countdown time.
In one example, the countdown time may be a countdown time set by the anchor user. For example, the anchor user sets the countdown through a countdown setting control on the live broadcast interface, and the live broadcast client receives a setting instruction based on the countdown setting control to obtain the countdown. On one hand, the countdown function can be started immediately when the countdown is obtained, the countdown is sent to other live broadcast clients of the live broadcast room, and the video data is stopped from being uploaded when the countdown is completed. On the other hand, after the countdown is obtained, when a certain set trigger condition is met, the countdown function is started, the countdown is sent to other live broadcast clients in the live broadcast room, and the video data is stopped from being uploaded when the countdown is completed.
In another example, the countdown time may also be a pre-specified time, and when the countdown triggering instruction is received, the countdown function is started, and the countdown time is sent to other live broadcast clients in the live broadcast room, and when the countdown is completed, the uploading of the video data is stopped. For example, the countdown triggering instruction may be an off-air instruction, and the countdown may be a delay time to stop uploading the video data. Specifically, when the anchor user needs to stop playing, the anchor user clicks a play stop button, at this time, a countdown function is triggered, preset countdown time is sent to other live broadcast clients in the live broadcast room, and when countdown is completed, video data uploading is stopped. The preset countdown time can be 5s, 10s, 15s and the like, and is configured according to requirements.
As can be seen from the above embodiments, in the present embodiment, the time for stopping uploading the video data is determined in a countdown manner, so that the current anchor can clearly stop uploading the time interval of the video data.
With respect to other live clients that send dead time information to the live room, in one example, the server device includes a video streaming server (also referred to as a media server). The live broadcast client in the main broadcast mode can send the off-air time information and the video data to the video stream server, and the video stream server sends the off-air time information and the video data to other live broadcast clients in the live broadcast room. In another example, the server devices include a video streaming server (also referred to as a media server) and a service server. The live broadcast client in the main broadcast mode can send the information of the off-air time to other live broadcast clients in the live broadcast room through the service server, and send video data to other live broadcast clients in the live broadcast room through the video streaming server. Because the existing service server can transmit communication information and the video streaming server can transmit video data, the video streaming server is not required to be utilized to transmit the off-air time information, so that the video streaming server is not required to be changed, and the waste of manpower and material resources caused by the change is avoided.
And when the live client in the main broadcasting mode determines that the off-air time reaches according to the off-air time information, stopping uploading the video data. When uploading of video data is stopped, in one example, the live room can be exited. In another example, the video data of the current main broadcast can be switched to the video data of the next arbitrary main broadcast for playing according to the wheat sequence list, and the mode is switched to the audience mode.
Therefore, in the embodiment, the current anchor does not need to exit the live broadcast room, and the current anchor can be converted into the audience to watch the video data uploaded by the next anchor, so that the fast switching between different modes is realized, and the interactivity between different anchors is enhanced.
In an optional implementation manner, after the stop time information is sent and before uploading of video data is stopped, if it is determined that a next anchor exists according to the wheat sequence list and video data of the next anchor is not received, a message for reminding that the wheat rotation fails is output.
And after the off-air time information is sent and before the uploading of the video data is stopped, when the existence of the next anchor and the video data of the next anchor are determined in the period, the reminding information of the failure of the wheeling microphone can be output. The reminder may be "wheel failed! "," no video data of the next anchor is received ", and the like. The current anchor can cancel the stop play according to the reminding information and continue the live broadcast. The current anchor can also inform the next anchor to remind the next anchor to upload video data and the like.
Therefore, the current anchor is reminded by outputting the reminding information of the wheeling wheat failure, so that the current anchor can take corresponding rescue measures, and the condition of video cutoff caused by the wheeling wheat failure is avoided.
Next, a live client in audience mode is introduced.
When the live client is in the audience mode, the video stream data of the current anchor can be played. The audience user can perform wheat robbing in the live broadcast watching process, if the wheat robbing is successful, the audience user becomes a prepared main broadcast, and the information of the main broadcast is stored in a wheat sequence list. If there are several viewers successfully robbed the wheat, i.e. there are several preliminary anchor, the anchor identifications of different anchors can be recorded in the wheat sequence list in turn-round order, so that the turn-round can be performed in turn-round order during the turn-round process. The wheat wheeling sequence can be determined according to the time sequence of successful wheat robbing, and the users arranged at the top have the priority of live broadcast and can carry out live broadcast at the top. The anchor identity may be a user name or the like used to represent the identity of the anchor.
The live client in audience mode can not only display the video data of the current anchor, but also receive the information of the off-air time. After the information of the off-air time is received, whether the current audience is the next anycast can be judged according to the wheat sequence table, and if the current audience is the next anycast, the mode is switched to the main-air mode. Under the anchor mode, the equipment where the live broadcast client side is located can collect video data, and the live broadcast client side can send the collected video data to other live broadcast client sides of a live broadcast room and display the video data in a local side. Therefore, the client of the next anchor is switched from the audience mode to the anchor mode, the live broadcast client does not play the video data of the current anchor any more, but plays the video data collected by the live broadcast client, and sends the collected video data to other live broadcast clients in the live broadcast room.
In one example, when the current audience is determined to be the next main broadcast according to the wheat sequence list, the mode is switched to the main broadcast mode, the broadcast control can be output by the broadcast interface, the main broadcast function of the live client is started when a trigger instruction is received based on the broadcast control, the device where the live client is located can collect video data, the collected video data is sent to other live clients of the live broadcast room through the server, and the video data is displayed at the live client.
Therefore, the live interface in the audience mode has no play control, and the live interface in the anchor mode is provided with the play control, so that the next anchor clicks the play control to play, the random play of the audience is avoided, and the rapid switching between the audience mode and the anchor mode is realized.
In one example, the next anycast may send video data to the video streaming server, where the video data carries a video stream ID, and the video stream ID may be composed of a live room number and a next anycast number, for example. The video stream server automatically broadcasts the video stream ID to other live broadcast clients (including a live broadcast client of the current anchor and a live broadcast client of the audience) in the live broadcast room, and the other live broadcast clients can subscribe the video stream in the video stream server according to the delivered video stream ID, so that the video stream server sends the video data to the other live broadcast clients.
Because the next anchor can send the video data to other live broadcast clients in the live broadcast room, both the live broadcast client of the current anchor and the live broadcast client of the audience can receive the video data sent by the next anchor. The live client can exchange the video data of the current anchor and the video data of the next anchor into the memory. And when the live broadcast client in the audience mode determines that the current audience is not the next main broadcast according to the wheat sequence list, the video data of the current main broadcast can be continuously played. And when the stop time is determined to arrive according to the stop time information, switching the video data of the current main broadcast into the video data of the next main broadcast according to the wheat sequence table for playing, thereby realizing the smooth transition of the video data and avoiding the situation of flow break.
When the client is live broadcast, corresponding video data can be acquired by using the video stream ID according to the progress of the stop time information.
