Embodiment Construction
[0045] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.
[0046] As shown above, due to the refresh jitter of the graphics card, the refresh interval (refresh period) will have a certain gap. Some of the frame loss during video playback is caused by uneven clock movement, and the refresh rate of the graphics card cannot be modified at the software level. The inventor thought that the frame loss of the video can be reduced to a certain extent by correcting the clock.
[0047] figure 1 It is a flowchart of a method for playing a video provided by an exemplary embodiment. Such as figure 1 As shown, the method can include the following steps:
[0048] Step S11: Calculate the theoretical refresh period of the graphics card a...

The invention relates to a video output method and device, a storage medium and electronic equipment. The method comprises the following steps: calculating a theoretical refresh cycle according to therefresh frequency of a display card; when the video card is applied to play the video, recording the actual refreshing moment of the video card in the current refreshing period; predicting N theoretical refresh moments of N refresh cycles after the current refresh cycle according to the theoretical refresh cycle and the actual refresh moment of the current refresh cycle; recording the actual refreshing moment of the display card in the next refreshing period; determining a theoretical refreshing moment closest to the recorded actual refreshing moment of the next refreshing period in the N theoretical refreshing moments as a target refreshing moment of the next refreshing period; and controlling the display to play the image frame corresponding to the target refresh moment of the next refresh period in the video. Thus, the played video is refreshed according to the corrected clock, and the corrected clock moves relatively uniformly, so that frame loss is avoided when the video is played, and the playing quality is improved.
Description
Technical field [0001] The present disclosure relates to the field of image output technology, and in particular, to a method and device, storage medium, and electronic equipment for playing video. Background technique [0002] At present, people have higher and higher requirements for the playback quality of the videos they watch, and the higher the frame rate and resolution of the video itself, the better. Since the picture displayed on the monitor is output by the graphics card, the different refresh frequency of the graphics card results in different effects of playing videos. For example, if the refresh frequency of the display is 60HZ, the interval between each refresh is 16.6ms, that is, the interval between every two frames of images displayed is 16.6ms. [0003] However, the above refresh interval is only a theoretical value, and the actual refresh interval of the graphics card is not necessarily 16.6ms every time. The actual situation is due to the refresh jitter of the...
