[0024] figure 1 It is a flow chart of a method for locating a video image frame in the first embodiment of the present invention. The method of this embodiment can be executed by a device for locating a video image frame. The device can be implemented by means of hardware and / or software, and It is integrated in the terminal device where the video player is located and used in conjunction with the video player, or as a subroutine of the video player. The method of this embodiment specifically includes the following steps:
[0025] Step 110, acquiring a video reference time.
[0026] In this embodiment, the terminal device acquires the video reference time.
[0027] Wherein, the video reference time is specifically used as a positioning starting point of a video image frame. Based on the video reference time, the terminal device accurately locates the video image frame that the user expects to obtain according to the relative adjustment time. From another perspective, the us...

[0049] figure 2 It is a flowchart of a video image frame positioning method according to the second embodiment of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, the step of obtaining the video reference time is preferably optimized as follows: according to the user's drag operation on the video playback progress bar, determine the time corresponding to the drag operation drag position; obtain the video playback time corresponding to the drag position, as the video reference time;
[0050] Preferably, the step is determined according to the video reference time and the relative adjustment time set by the user operation, and the video frame positioning time is optimized as follows: according to the frame adjustment number input by the user, or according to the frame adjustment number and the frame adjustment direction input by the user, determine Relative adjustment time; according to the video reference time and ...

[0071] image 3 It is a flow chart of a video image frame positioning method according to the third embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, it is preferable to optimize the relative adjustment time according to the frame adjustment number and frame adjustment direction input by the user as follows: when the frame adjustment direction input by the user is forward direction, according to the frame adjustment number M input by the user and the frame interval ΔT of the video, determine the relative adjustment time as M*ΔT; when the frame adjustment direction input by the user is the backward direction, adjust the number N and the video frame according to the user input Frame interval ΔT, determine the relative adjustment time as -N*ΔT; where, M and N are integers greater than or equal to 1;
[0072] Preferably, the step of determining the video frame positioning time according to the vi...
