Abstract

A method for video playback. The method for video playback comprises the steps of: detecting a video to be played back in a buffer area, acquiring an identifier of the video to be played back; determining, on the basis of the identifier, whether the format of the video to be played back is switched to a high dynamic range image format; when the format of the video to be played back is switched to high dynamic range image, acquiring in real-time a first preset parameter, where the first preset parameter is a parameter of an image corresponding to a high dynamic range image format video; adjusting, on the basis of the first preset parameter, a parameter value of an image of the video to be played back and playing back the video to be played back. A device for video playback. Upon detecting that the format of the video to be played back is switched to the high dynamic range image, the parameter value of the image is adjusted on the basis of the first preset parameter, and then the video to be played back is played back, thus obviating the step in which a user manually calls a menu to adjust the parameter value of the image when the format of the video to be played back is switched, and providing increased degree of convenience and smartness.
