All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, in one embodiment, a live method is provided, which is applied to a client. The live broadcast method specifically comprises the following steps:
and 102, after sending a live broadcast request to the server, establishing live broadcast connection and generating a real-time live broadcast picture.
The real-time live broadcast picture refers to a video picture when the client performs live broadcast. Specifically, after sending a live broadcast request to the server, the client enters a live broadcast application to generate a live broadcast video picture. The client is a live broadcast end for live broadcast, and the client can be a webpage end for live broadcast on a webpage or a live broadcast end for live broadcast on an application program end (such as an APP end).
And 104, receiving a file to be live broadcast sent by the server, wherein the file to be live broadcast comprises a plurality of pictures.
The file to be live broadcast is a PPT file which needs to be displayed in real time in the live broadcast process and is used for supplementing a real-time live broadcast picture. Specifically, a user uploads a file to be live broadcast in advance on a server, the server transcodes the file to be live broadcast, the PPT file is converted into pictures, and each PPT corresponds to one picture. In the embodiment, the PPT file is converted into the corresponding picture, so that multi-terminal compatibility is better supported, the compatibility of the file to be live-broadcasted at different clients is improved, and the live broadcasting effect is further ensured.
And 106, if a selection operation instruction of the file to be live broadcast is detected, acquiring a selected target picture from the file to be live broadcast.
The selection instruction refers to a command which is sent to the client side by the user and used for determining that the picture needs to be displayed from the file to be live broadcast. The target picture is a picture selected by the user and used for displaying in the live broadcasting process. For example, a picture of a file to be live broadcast may be displayed at a client, and the client may use the picture determined by a detected selection operation instruction of the file to be live broadcast, such as a page number positioning instruction or a page turning instruction, as a target picture.
And 108, synchronously displaying the real-time live broadcast picture and the target picture according to a preset arrangement mode.
Specifically, after the client acquires the target picture, the real-time live broadcast picture and the target picture are synchronously displayed according to a preset arrangement mode, wherein the preset arrangement mode can be that the target picture is located above and is vertically arranged or horizontally arranged with the real-time live broadcast picture, so that double-screen live broadcast of the live broadcast picture and the supplementary information is realized, a user watching the live broadcast can quickly acquire comprehensive live broadcast information, and the live broadcast effect is greatly improved.

and 112, generating a playback video based on the target picture and the time line of the real-time live broadcast picture corresponding to the live broadcast picture.
Specifically, the client records the time for displaying the real-time live broadcast picture and the corresponding target picture at the same time to generate a live broadcast timeline, and meanwhile, the client generates the real-time live broadcast picture and the target picture and the timeline corresponding to the live broadcast picture into a playback video. Therefore, after the live broadcast is finished, the user can also experience the video effect of the live broadcast and PPT file double-screen display after entering the live broadcast, and the live broadcast effect is further improved.
As shown in fig. 3, in one embodiment, the method further comprises:
and step 116, playing back the playback video and displaying the target picture based on the time line of the target picture in the playback video.
In this embodiment, when receiving a live playback instruction, the client acquires a playback video according to the instruction; when the video is played back, the time lines of the target pictures are recorded, so that the client automatically displays the target pictures to the user according to the target pictures corresponding to the time lines, and the target pictures in the played back video are switched and displayed along with a real-time live broadcast picture. The method and the device ensure that the user obtains more comprehensive supplementary information by watching the playback video, and further improve the user experience.
In one embodiment, the predetermined arrangement is an up-down arrangement or a left-right arrangement.
In this embodiment, the top-bottom arrangement may be that the target picture is located above and the live view is located below, or that the target picture is located below and the live view is located above. The left and right arrangement can be that the target picture is located the left, the live broadcast picture is located the right, also can be that the target picture is located the right, the live broadcast picture is located the left, can set up according to actual demand. Understandably, the real-time live broadcast pictures and the corresponding target pictures are arranged vertically or horizontally, so that double-screen display of the real-time live broadcast pictures and the corresponding target pictures is realized, and the effect of watching live broadcast or playing back videos by a user is improved.
