The online transaction video recording method provided by the invention can be applied to a live broadcast server, and the live broadcast server can be called a live broadcast middle station. The online transaction audio and video recording scheme is based on audio and video capability, the implementation of the audio and video capability can be based on audio and video cloud, and the audio and video basic capability can be improved in a self-built mode without depending on the audio and video cloud. If the audio/video cloud is supported, the live broadcast server needs to interact with the audio/video cloud server to acquire audio/video data.
And the live broadcast middle station monitors information of the client entering and exiting the live broadcast room, and starts a whole-course recording task after monitoring that the first client enters the live broadcast room. And displaying the video picture of the first client on a display window at a corresponding position on a preset canvas.

The live broadcast middle station continues to monitor information of other clients entering and exiting the live broadcast room, and when knowing that the other clients enter the live broadcast room, video pictures of the other clients are displayed on display windows at corresponding positions on a canvas. When the video pictures of each client are displayed, the corresponding video pictures are displayed on the display window on the canvas according to the entering sequence and the preset layout. For example, in order of entry, in line. And, when the client exits the live broadcasting room, the corresponding display window is reserved, and the reservation means that the display window still belongs to the exiting client and is not distributed to other clients, and the display style of the display window is not limited, for example, gray setting can be performed. And recording videos of a plurality of clients, namely realizing multi-angle recording.
Fig. 2 is a schematic diagram of multi-angle recording and displaying in the online transaction video recording method provided by the invention. As shown in fig. 2, taking an on-line sign as an example, from the first user to enter an on-line sign room (which can be understood as a living broadcast room), the whole-process recording starts, such as "recorded video" in fig. 2, and because of multi-angle recording, mixed streaming is performed here, video pictures of different users are sequentially arranged on a large canvas (black canvas is taken as an example here), and the layout of the user pictures can be designed according to the requirements of the demander, so that the user pictures are flexible and changeable. When a certain user goes offline or drops, the window is not deleted, but remains, when he goes online again, the window still appears (for example, the 1 st window on the left side still appears after the user 1 goes offline and comes online again), and the information of the first entering sequence of the user is kept.
According to the online transaction video recording method provided by the invention, after the whole recording task is started, each client side displays the corresponding video picture on the display window on the canvas according to the entering sequence and the preset layout, so that multi-angle recording is realized, and the information of the first entering sequence of a user is reserved.
The online transaction video recording method is characterized in that the room number of the live broadcasting room corresponds to the task ID of the whole-process recording task one by one; the method further comprises the steps of: after generating a video clip, inquiring whether a task which is being spliced exists currently or not according to the task ID, if so, pushing the video clip into a task queue to be processed corresponding to the task ID; if not, judging whether the task queue to be processed has videos to be spliced or not, if so, splicing the video clips and the videos to be spliced to obtain a new summarized video and storing the new summarized video.
Since a transaction process is sometimes not necessarily completed in a short time, if it is not completed in a short time, it may involve the situation of continuing the recording of the last transaction, that is, a plurality of video clips corresponding to the same online transaction may occur. Or, due to equipment failure during recording, multiple video clips corresponding to the same online transaction may also be caused. At this time, the video clips formed by each recording need to be spliced to obtain a complete video corresponding to a certain online transaction. One transaction process corresponds to one task ID, so that the related videos can be integrated and spliced conveniently according to the task ID. After the video is interrupted and when the last recording is continued, the same live broadcasting room is still entered for recording. The living room may be distinguished by room number. Therefore, the room number of the live broadcasting room and the task ID of the whole recording task are in one-to-one correspondence, and video splicing can be performed according to the task ID.
When in splicing, the splicing tasks of different task IDs can be performed in parallel. For video of a certain task ID, after a certain video segment is generated, inquiring whether a task which is being spliced exists currently according to the task ID, wherein the task which is being spliced currently refers to that the video segment with the same task ID is executing the splicing task. If yes, pushing the video clip into a task queue to be processed corresponding to the task ID; if the task to be spliced does not exist, judging whether the task queue to be processed has the video to be spliced, if so, splicing the video segment and the video to be spliced to obtain a new summarized video and storing the new summarized video.
Fig. 3 is a schematic flow chart of video splicing in the online transaction video method provided by the invention. As shown in fig. 3, taking on-line transaction video based on an audio/video cloud as an example, a video stitching algorithm is as follows:
(1) And receiving a video callback of the audio and video cloud server, wherein the video callback comprises a video file url, a service ID (task ID) and the like.
(2) Inquiring whether a task which is being spliced exists currently according to the service id, and if so, entering the step (3). There is no entry into step (4).
(3) Pushing the video into a task queue to be processed corresponding to the service id.
(4) And inquiring the corresponding queue details according to the service id.
(5) Judging whether the video waiting for splicing exists in the queue, if yes, entering the step (6), and if not, entering the step (7).
(6) And (4) starting to execute a splicing task, summarizing the video to be processed and the previous splicing result to obtain a new summarized video, and entering the step (4).
(7) And (5) ending.
Because the transaction process can not last for a long time and can be completed in one day generally, the summary video obtained finally by the task queue to be processed can be downloaded according to the actual situation of the online transaction, and the complete video of the corresponding online transaction can be obtained.
According to the online transaction video recording method provided by the invention, the task queue to be processed corresponding to the task ID is set, and the video to be spliced in the task queue to be processed and the newly generated video segments are spliced according to the task ID to obtain the new summarized video, so that the splicing of the video segments is realized, the complete video is obtained, and the video watching requirement is met.
