Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.
The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.
Based on the hardware structure of the mobile terminal, the invention provides various embodiments of the method.
Example one
Based on fig. 2, a method for playing a video according to an embodiment of the present invention is shown, where the method may include:
s201: when a terminal plays a video file with geographical position information, analyzing the video file to acquire video information, audio information and geographical position information contained in the video file;
s202: the terminal searches the geographic position information in the video file according to the geographic position to be inquired in the received inquiry instruction;
s203: when the geographical position to be inquired is searched in the geographical position information of the video file, the terminal is positioned to a first timestamp corresponding to the geographical position to be inquired;
s204: and the terminal plays the corresponding video information and audio information by taking the first time stamp as a starting point.
It should be noted that the video file according to the embodiment of the present invention is a video file having geographic position information, and in the recording process of the video file, the obtained geographic position information is stored in a position track of the video file and is associated with a timestamp (PTS) of the position track, so that a geographic position sequence can be formed according to the sequence of the video file position track timestamps. Preferably, when a video of 30 Frames Per Second (FPS) is recorded, a geographical location information (e.g., latitude and longitude information) is stored every 1800 frames, and then the video records a geographical location information every 60 seconds. According to the recording process of the video file with the geographical location information, it can be known that: and the geographic position information of the video file corresponds to the time stamps of the video file one by one.
Illustratively, the searching, by the terminal, the geographic location information in the video file according to the geographic location to be queried in the received query instruction may specifically include:
when the geographic position information of the video file has geographic position information meeting a preset error condition with the geographic position to be inquired, determining that the geographic position to be inquired is searched in the geographic position information of the video file by the terminal;
when the geographic position information of the video file does not have geographic position information meeting a preset error condition with the geographic position to be inquired, determining that the geographic position to be inquired is not searched in the geographic position information of the video file by the terminal.
It should be noted that, when the number of the video files is multiple, the video file of the geographical position to be queried, which is searched from the geographical position information of the multiple video files, is used as the searched video file.
It can be understood that, when the geographic location to be queried in the query instruction sent by the user is not exactly in the geographic location information of the video file, the terminal may determine, according to a preset error condition (for example, only two digits after a decimal point of a longitude and latitude coordinate of the geographic location to be queried is reserved according to preset precision processing), the geographic location information located near the address location to be queried in the video file as the geographic location to be queried searched by the terminal in the video file.
It should be further noted that, when the geographic location information of the video file includes a plurality of pieces of geographic location information that satisfy a preset error condition with the geographic location to be queried, the method may further include: and the terminal is positioned to a first time stamp corresponding to the geographical position information of which the geographical position to be inquired meets the preset error condition.
It can be understood that, when there are a plurality of geographic location information in the video file and the geographic location to be queried satisfy the preset error condition, the geographic location sequence formed by combining the geographic location information of the video file is formed, so that the first timestamp positioned by the terminal in the video file is the first timestamp corresponding to the geographic location information of which the geographic location to be queried satisfies the preset error condition.
Based on the foregoing technical solution, referring to fig. 3, the method may further include:
s301: when a terminal plays a video file with geographical position information, drawing a motion track in a map according to the geographical position information of the video file;
s302: and the terminal establishes a corresponding relation between each motion track point and the geographical position information.
Specifically, by combining the geographical position sequence formed by the geographical position information of the video file, the movement track can be drawn on the map according to the geographical position sequence formed by the geographical position information, and the movement track can be displayed on the display unit of the terminal. As shown in the terminal display interface of fig. 4, the video file played in the playing window is a video file shot by the car recorder during the journey from sha, zheng, wuhan, and changsha to guangzhou when the user drives a car, and the video file includes the geographical location information, so that the movement track shown by the black bold line can be drawn on the map shown in the map display window according to the geographical location information, and the corresponding relationship between each movement track point and the geographical location information is established. Therefore, when the terminal plays the video file, the motion track on the map is marked according to the geographic position information corresponding to the video content being played, specifically as shown by a hollow circle in fig. 4, and when the played video content is that the user drives to the yellow crane building in wuhan, the geographic position of the yellow crane building in wuhan is correspondingly marked on the motion track of the map.
Accordingly, as shown in fig. 5, the method may further include:
s501: the terminal receives a positioning instruction of the motion track point and obtains a motion track positioning point in the positioning instruction;
s502: the terminal acquires the geographical position information corresponding to the movement track positioning point;
s503: the terminal acquires a second timestamp corresponding to the geographic position information corresponding to the motion track positioning point in the video file;
s504: and the terminal plays the corresponding video information and audio information by taking the second time stamp as a starting point.
It should be noted that, in the specific implementation process, the user may perform positioning on the motion trajectory, that is, the terminal may receive a positioning instruction sent by the user dragging the annotation point on the motion trajectory graph displayed on the map display window of fig. 4, and obtain the motion trajectory positioning point in the positioning instruction, for example, as shown in fig. 6, when the user drags the annotation point to the southern lake broadcast and television building of the changsha, the terminal may use the annotation point on the motion trajectory at this time as the motion trajectory positioning point and obtain the geographic position information corresponding to the motion trajectory positioning point; after the geographical position information corresponding to the motion track positioning point is obtained, a second timestamp corresponding to the geographical position information corresponding to the motion track positioning point in the video file is obtained through query from the video file; and the terminal plays the corresponding video information and audio information in the video file by taking the second timestamp as a starting point. As shown in fig. 6, when the motion trail location point is dragged to the long-sand south of the lake radio and television building in the map, the video playing window plays video information and audio information of the user driving through the south of the lake radio and television building in the video file.
The embodiment provides a video playing method, which corresponds geographical position information in a video file to video content, so that the video content in the video file can be searched and positioned through the geographical position information, another searching and positioning dimension for the video content is provided besides a time dimension, and user experience is improved.
