Problems solved by technology
[0004] However, due to the limited size of the portable terminal, the size of the touch screen is also limited, so the length of the progress bar is also limited by the size of the touch screen, and due to the width of the human finger, when adjusting the progress, it is necessary to adjust the progress within a limited time. Drag a button with a small area on the progress bar, in this case, the precise positioning of the playback progress cannot be achieved
And along with the increase of the duration of audio and video files (such as a video file corresponding to a film), the complexity of accurately adjusting the playback progress will continue to increase, so that when the audio and video files exceed a certain duration, the playback progress of the audio and video files It is more difficult to realize precise fast forward and fast rewind control

A method and terminal for controlling the playback progress of multimedia files, wherein the method includes: during the process of playing multimedia files, the terminal receives the user's left / right sliding operation in the first area on the current playback interface; obtains Data related to the sliding operation; according to the corresponding relationship between the vertical coordinate of the sliding operation trajectory on the touch display screen and the adjustment speed, the adjustment speed corresponding to the vertical coordinate is determined, and the size of the vertical coordinate determines the size of the adjustment speed. ; Determine the direction for progress control of the current playback progress of the multimedia file according to the sliding direction; determine the progress adjustment value according to the sliding distance and the adjustment speed corresponding to the vertical coordinate, and determine the progress adjustment value according to the progress adjustment value Progress control is performed on the current playback progress of the multimedia file in the direction of progress control.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method and terminal for controlling the playback progress of multimedia files. Background technique [0002] With the development of portable terminals, such as terminals such as smart phones and Pads (tablet computers), more and more users use the portable terminals to play music or watch videos. During the process of playing music or watching video, the user may fast-forward or rewind the audio or video according to his own needs at any time, and most of the display screens of portable terminals are touch screens at present, so how to It is a problem that needs to be solved to effectively control the progress of audio or video playback on the touch screen. [0003] At present, in order to control the playback progress of multimedia (such as audio, video, etc.) in most applications, a horizontal progress bar is set on the page, which represents the entire playback progress ...
