The above embodiments introduce the contents of the hardware/software architecture, the functional implementation, and the like of the display device 200. In some application scenarios, when a user selects a certain video to play on the display device 200, in response to a play instruction input by the user, the display device 200 accesses a link address of a target video, obtains a target video file, where the target video file includes video frames arranged based on a play time sequence, and sequentially plays the corresponding video frames in the video play window 201 according to the play time sequence, so as to realize the play of the target video. When the user views the video in the video playing window 201, the playing progress of the video can be adjusted to play the video directly from the video picture of interest to the user.
In some embodiments, the adjustment of the playing progress of the video may be implemented by the control device 100. The control apparatus 100 may be a remote controller for controlling the display device 200, and the remote controller is provided with a direction key for adjusting the play progress of the video. The user sends a progress adjustment instruction of a corresponding direction to the display device 200 by pressing a direction key, the display device 200 adjusts the target video after receiving the progress adjustment instruction, and adjusts the playing progress of the target video once in the corresponding direction every time when receiving one progress adjustment instruction, wherein the value of the playing progress adjusted every time is the same. By means of the method, the playing progress of the target video is adjusted, although the video picture of interest to the user can be accurately positioned, if the duration of the target video is long, the user can only position the video picture of interest to the user by pressing a direction key for adjusting the playing progress of the video for many times. For example, the total duration of the target video is 2h30min, and each time the direction key for adjusting the playing progress of the video is pressed, the playing progress of the target video will advance or retreat for 5s, and if the playing progress of the target video is adjusted from 1min to 1h31min, 1080 times are required, which will certainly consume a great deal of time and effort for the user, so that the experience of the user is poor.
In some embodiments, referring to fig. 5, a play time axis 202 is further displayed in the video play window 201, different positions on the play time axis 202 correspond to different time points of the played video, a play progress bar 203 is displayed on the play time axis 202, and a user can adjust the video play progress by gradually dragging the play progress bar 203. In addition, referring to fig. 6, when the user controls focus to stay somewhere on the play time axis 202, a still video picture corresponding to the time stamp will be displayed, and the display of the still video picture may enable the user to know the video content therein, thereby assisting the user in adjusting the play progress to a desired position. By adjusting the playing progress of the video in the mode, the video picture can be previewed rapidly, but the video picture can only be roughly positioned near the video picture interested by the user, and if the video picture interested by the user is positioned accurately, multiple times of debugging are needed.
In some embodiments, when a user selects a certain video to play, the playing instruction input by the user is responded, the target video file is controlled to be played in the video playing window 201, the target video file is parsed, the total duration of the target video and the video frames corresponding to each time point are obtained, the interval duration of the section is set, and the target video is divided into a plurality of time segments. For example, the total duration of the video is 30min, the interval duration of the section is set to be 5min, then one time segment is set every 5min, and the total time segments of the video with the duration of 30min are 6. Wherein each time segment corresponds to a time period on the playback timeline 202, the time period on the playback timeline 202 representing the playback time of the corresponding group of video frames.
