The online transaction video recording method and apparatus provided by the present invention are described below with reference to fig. 1-14.
FIG. 1 is a flow chart of an online transaction recording method according to the present invention. As shown in fig. 1, the method includes:
step 101, monitoring information of a client entering and exiting a live broadcast room, starting a whole-process recording task if a first client entering the live broadcast room is known, and displaying a video picture of the first client on a display window at a corresponding position on a canvas.
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 middling station. The online transaction audio and video recording scheme is based on the audio and video capability, the audio and video capability can be realized based on the audio and video cloud, the audio and video basic capability can be improved in a self-building mode, and the audio and video cloud is not necessarily relied on. If the audio and video cloud is relied on, the live broadcast server needs to interact with the audio and video cloud server to acquire audio and video data.
And the live broadcasting middling station monitors information of the client entering and exiting the live broadcasting room, and starts a whole-course recording task after monitoring that the first client enters the live broadcasting room. And displaying the video picture of the first client on a display window at a corresponding position on a preset canvas.
And the live broadcasting middle station continuously monitors information of other clients entering and exiting the live broadcasting room, and displays video pictures of other clients on display windows at corresponding positions on the canvas when knowing that other clients enter the live broadcasting room. And when the video pictures of the clients are displayed, displaying the corresponding video pictures on the display window on the canvas according to the entering sequence and the preset layout. For example, the display is performed in sequence and in rows according to the entering sequence. And when the client exits from the live broadcast 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 required to be limited, such as graying and the like. The video of a plurality of clients is recorded, and multi-angle recording is also realized.
FIG. 2 is a schematic diagram illustrating multi-angle recording display in the online transaction recording method according to the present invention. As shown in fig. 2, taking online sign as an example, when a first user enters an online sign room (which can be understood as a live broadcast room), recording in the whole process starts, as "recorded video" in fig. 2, since the recording is performed in multiple angles, mixed flow is performed here, video pictures of different users are sequentially arranged on a large canvas (here, taking a black canvas as an example), and the layout of the user pictures can be designed according to the requirements of a demand party, and is flexible and variable. When a user goes down or drops off, the window is not deleted, but is kept, and when the user goes up again, the window still appears (for example, the 1 st window on the left side still appears after the user 1 goes off and goes back on), 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-process recording task is started, the corresponding video pictures are displayed on the display windows on the canvas by each client 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 the user is reserved.
The online transaction video recording method is characterized in that the room number of the live broadcast room corresponds to the task ID of the whole-course recording task one by one; the method further comprises the following steps: after generating a video clip, inquiring whether a task which is being spliced exists at present according to the task ID, and if so, pushing the video clip into a task queue to be processed corresponding to the task ID; if not, judging whether the video waiting for splicing exists in the task queue to be processed, if so, splicing the video segments and the video waiting for splicing to obtain a new summary video and storing the new summary video.
Since a transaction process may not be completed for a short time, if not, it may involve continuing recording of the last transaction, i.e., multiple video clips corresponding to the same online transaction may occur. Or, due to equipment failure during recording, etc., there may be multiple video segments corresponding to the same online transaction. At this time, the video segments formed by the recordings need to be spliced to obtain a complete video corresponding to a certain online transaction. One transaction process corresponds to one task ID, and related videos are conveniently integrated and spliced according to the task ID. And after the video recording is interrupted and the last recording is continued, the same live broadcast room is still accessed for recording. Live rooms can be distinguished by room number. Therefore, the room number of the live broadcast room and the task ID of the whole-course recording task are in one-to-one correspondence, and video splicing can be performed according to the task ID.
When splicing, splicing tasks of different task IDs can be performed in parallel. For the video with a certain task ID, after a certain video segment is generated, whether a task which is being spliced exists at present is inquired according to the task ID, wherein the task which is being spliced exists at present means that the video segment with the same task ID is executing a splicing task. If yes, pushing the video clip into a task queue to be processed corresponding to the task ID; if the task which is being spliced does not exist, judging whether a video to be spliced exists in the task queue to be processed or not, if so, splicing the video clip 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 recording method according to the present invention. As shown in fig. 3, taking online transaction video recording based on audio and video cloud as an example, the video splicing algorithm is as follows:
(1) and receiving a video call-back of the audio and video cloud server, wherein the video call-back comprises a video file url, a service ID (task ID) and the like.
(2) And (4) inquiring whether the task which is spliced currently exists or not according to the service id, and entering the step (3) if the task which is spliced currently exists. There is no entry to step (4).
(3) And 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) And (4) judging whether the video waiting for splicing exists in the queue, wherein the step (6) is carried out, and the step (7) is not carried out.
(6) And (5) starting to execute the 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 (6) ending.
Because the transaction process can not last too long and can be completed in one day, the finally obtained summary video of 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, 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 segment are spliced according to the task ID to obtain the new summary video, so that the splicing of the video segments is realized, the complete video is favorably obtained, and the video watching requirement is met.
