Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a video playing processing method for forest fire monitoring according to an embodiment of the present invention. As shown in fig. 1, the video playing processing method includes the following steps:
s11: a first server acquires an original video stream;
the original video stream is from video data transmitted by cameras arranged at various monitoring positions of the forest.
Preferably, the original video stream is obtained based on an rtsp protocol, that is, the original video stream is an rtsp video stream.
S12: slicing the original video stream to generate a sliced video file;
referring to fig. 2, fig. 2 is a flowchart illustrating an embodiment of step S11 of fig. 1. As shown in fig. 2, this step includes the following sub-steps:
s121: capturing video frames through a frame grabber;
s122: starting a plurality of video recorders to record a plurality of video files;
s123: and when the recording time reaches the preset recording time, stopping recording, and synthesizing the plurality of video files into the slice video file.
In step S123, for example, the preset recording time is set to 10S, and when the recording time reaches 10S, recording is stopped and video file synthesis is performed.
Preferably, the preset recording time is a reasonable time, so that the slice video file can keep a proper length, the speed of the front end for playing the video file for the first time is increased, and the playback is free from a pause phenomenon.
S13: storing the sliced video file in a container of a second server;
in step S13, the slice video file is stored in the form of a still file. The container employs the following types of storage servers: nginx storage server, or tomcat storage server.
S14: the front-end component is notified to play the sliced video file.
The front-end component is an application plug-in arranged at the Web client.
When one slice video file is stored in step S13, this step S14 is executed. Preferably, after 3 to 4 slice video files are stored in step S13, the present step S14 is performed. This ensures that the video is not stuck.
Preferably, steps S12 and S13 are performed in an asynchronous thread. In this way, if the step S12 or the step S13 fails to be executed, the operation of playing the video in the step S14 is not affected, and the front-end user is prevented from dropping the video.
In the embodiment, the slice video file to be played is stored in the second server, so that the load of the first server can be reduced, and the video monitoring image can be stably and smoothly played at a Web end.

between step S22 and step S24, the method further includes the sub-step S23: and judging whether the total number of the slice video files in the container reaches a preset value, and if so, deleting the slice video file which is stored firstly in the container.
For example, the preset value is set to 10, and when the total number n of the slice video files in the container is greater than 10, the first to n-10 th slice video files in the container are deleted, so that the total number of the slice video files in the container is guaranteed to be 10.
It is understood that if the steps S22 and S24 are executed in asynchronous threads, the steps S23 and S24 are located in the same thread.
In this embodiment, as the playing time is longer, the total number of the slice video files in the container is gradually increased, and the total number of the slice video files in the container is kept to be a preset value, so that the load of the second server can be reduced, and the video monitoring image can be stably and smoothly played at the Web end.
