Based on the hardware structure of the video recording device, the embodiments of the video recording method are provided.
The invention provides a video recording method.
Referring to fig. 2, fig. 2 is a flowchart illustrating a video recording method according to a first embodiment of the present invention. In this embodiment, the image display method includes the steps of:
step S10, receiving video operation information sent by the application operation scheduling device 110, where the video operation information includes operation actions, operation time, and operation video information;
the user performs an operation on the currently played video on the interactive interface of the application operation scheduling device 110. It can be understood that the application operation scheduling interface is provided with a soft play area having a mapping relation with the display screen 160, and the display screen 160 can respond to the display change of the soft play area in real time when the video in the soft play area is operated. The application operation scheduling device 110 can generate video operation information corresponding to various operations performed by the user on the display video in the soft play area.
The video operation information includes operation actions, operation time and operation video information, where the operation actions refer to operations performed by a user on data displayed on the current display screen 160, and include actions of screen up, screen down, zooming, moving, recording, and ending, the screen up refers to starting playing a new video stream on the screen, the screen down refers to ending playing a video already displayed on the screen, the zooming refers to reducing or enlarging the size of a video already displayed on the screen, the moving refers to changing the position of a video displayed on the screen, recording starts to record the video being displayed, and recording ends, that is, recording ends to record the video being displayed. The operation time is the time when the video operation information is generated or the time when the user triggers the generation of the video operation information. The operation video information refers to an object currently operated by a user, such as a video stream needing to be displayed on a screen or a video stream needing to be zoomed.
It should be noted that the operation video information mainly stores the video display information on the display screen 160 after the display screen 160 responds to the current operation node of the user, including the number of video streams displayed on the display screen 160 after the current operation node, and the corresponding data source of each video stream.
In this embodiment, the display screen 160 is preferably a tiled matrix screen, i.e., the display screen 160 is composed of a plurality of sub-display screens 160 that are independently displayed. The video operation information sent by the application operation scheduling device 110 is video operation information for one operation node, and when one video is displayed on the display screen 160, the application operation scheduling device 110 sends a plurality of pieces of video operation information of one video, that is, recording of a single video is realized. When multiple videos are displayed on the display screen 160, the application operation scheduling device 110 sends a plurality of video operation information of each video, i.e. recording of multiple videos is achieved.
Step S20, obtaining a corresponding target video stream from the preset data source 130 according to the operation video information;
the operation video information comprises operation actions, operation time and operation video information. And operating the video information, namely, operating the operation object of the current operation node of the user. The preset data source 130 stores a plurality of video streams, and a plurality of pieces of video stream information may be displayed on the interactive interface of the application operation scheduling device 110, and a user may play the target video stream by dragging the target video stream to the soft play area, and when the target video stream is zoomed, moved, and the like in the soft play area, video operation information of each operation node may be generated. When a user triggers an operation on a certain target video stream, the application operation scheduling device 110 generates video operation information from the operation triggered by the user and sends the video operation information to the recording and playing server 120, and the recording and playing server 120 receives the video operation information and acquires the target video stream from a preset database according to the operation video information contained in the video operation information. The operational video information includes the ID address of the data source 130. The data source 130 may be an encoder or a third party video providing platform.
And step S30, analyzing the operation actions in sequence according to the operation time, forming node information files according to the analysis result, and storing the node information files and the corresponding target video streams of each operation action in corresponding video recording file packages.
Upon retrieving the target video stream from the preset data source 130, the processor 1001 can save the target video stream in the memory 1005. The processor 1001 obtains information of an operation action and information of operation time from the video operation information, parses the information of the operation action, and forms a node information file according to a result of the parsing, where the node information file includes target video stream information of a current operation node, a display window position and a display window size of the target video stream, and size and resolution information of the display screen 160, and the formed node information file is stored in the memory 1005. And then encapsulating the node information file of each operation action and the corresponding target video stream to form a corresponding video recording file packet.
The forming process of the video recording file package can be understood as that when video operation information of a current operation node is received, a corresponding target video stream is obtained from a data source and stored, a node information file is formed and stored according to operation action analysis of the current operation node, and finally the obtained target video stream and a plurality of node information files are stored in the video recording file package corresponding to the route change video, namely at least one target video stream and a plurality of node information files are stored in the formed video recording file package. The node information file is stored in a JSON file format. A plurality of target video streams are stored in a storage container in a unified manner.
It should be noted that each operation action correspondingly forms a node information file, when a user triggers multiple pieces of video operation information in a video, multiple node information files are correspondingly generated, and when a video is played, the multiple node information files are read according to the sequence of operation time, and a corresponding target video stream is played according to the node information file decoding. In order to realize sequential reading of a plurality of node information files, each node information file may be time-stamped, and when an operation node is reached, the corresponding node information file is read.
According to the technical scheme of the embodiment, when the video is recorded, a time axis from the beginning of recording to the end of recording is taken as a main line, and then corresponding operations at each time point with operation change are recorded, wherein the main recording operations comprise video and audio screen up and down, video movement, zooming and other operations. Video resources are recorded and stored in a resource mode (namely one path of stream is one file) so as to ensure the absolute reality and the original definition reduction of the video; during playback, the recording and playing service synchronously plays back according to the recorded time axis, the operation process of the whole original scene is completely and really reproduced, meanwhile, one path of video corresponds to one video recording file package, a plurality of target video streams and a plurality of node information files are stored in the video recording file package, each operation node corresponds to one node information file, even if the node information file of one operation node is damaged, reading of the node information files of other operation nodes cannot be influenced, and the safety of the recorded files is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a video recording method according to a second embodiment of the present invention. Based on fig. 2, step S20 in this embodiment further includes, before:
step S11, determining whether the previous operation video information is the same as the current operation video information;
if the previous operation video information is not the same as the current operation video information, step S20 is executed to obtain a corresponding target video stream from the preset data source 130 according to the current operation video information. If the last operation video information is the same as the current operation video information, step S30 is executed.
In the process of recording one path of video, there are various operation actions in the video operation information triggered by the user, such as screen up, screen down, zooming, and moving. When the operation is performed as the top screen or the bottom screen, at this time, a new target video stream needs to be put on the display screen 160 for display, and at this time, since the recording and playing server 120 never obtains the new target video stream from the data source 130, the recording and playing server 120 needs to obtain the new target video stream from the corresponding data source 130 according to the operation video information. When the operation action is zooming or moving, only the size and the position of the video being displayed need to be changed at this time, and a new video stream does not need to be introduced, that is, the recording and playing server 120 has already obtained the target video stream being displayed from the corresponding data source 130, at this time, the recording and playing server 120 does not need to obtain the target video stream from the data source 130 according to the operation video information. By the technical scheme, the recording synchronization is guaranteed, and the recording delay is slowed down. After obtaining the video operation information of the current operation node, the processor 1001 compares the operation video information of the current operation node with the video operation information of the previous operation node, and determines whether the previous operation video information is the same as the current operation video information. If the previous operation video information is not the same as the current operation video information, the target video information of the current node is obtained from the corresponding data source 130, that is, step S20 is executed. If the previous operation video information is the same as the current operation video information, the corresponding target video stream is acquired from the corresponding memory 1005, and then step S30 is executed.
Referring to fig. 4, fig. 4 is a flowchart illustrating a video recording method according to a third embodiment of the present invention. Based on fig. 1, step S20 in this embodiment further includes, before:
step S40, receiving an externally triggered playback request;
step S50, according to the playback request, sending a plurality of node information files corresponding to the playback request to the display screen 160, so that the display screen 160 reads the node information files according to the recording order, and loads and decodes the corresponding target video stream according to the node information files.
After the recording of the video is realized through the method, when an externally triggered playback request is received, the plurality of node information files corresponding to the playback request are sent to the display screen 160 according to the playback request, so that the display screen 160 reads the node information files according to the recording sequence, and loads and decodes the corresponding target video stream according to the node information files. After receiving the plurality of node information files sent by the recording and playing server 120, the display screen 160 first reads each node information file to obtain the position of each operation node on the whole recording time axis, then loads a target video stream according to each node information file, and plays the decoded target video stream according to each node information. At this time, the recording and playing server 120 serves as a data source 130 for providing the video stream to be played to the display screen. Typically, the playback request includes the requested device information (display screen 160 or other third party display device), the video content (including which video files were requested), and the like. A requesting device, such as display screen 160, receives a plurality of node information files belonging to the same way.
