Abstract
The invention introduces a method for determining frame resolution, performed by a processing unit, which contains at least the following steps: obtaining a YUV video file, which contains a video stream; selecting a plurality of frame resolutions from a frame resolution table as frame resolution candidates according to the length of the video stream; repeatedly executing a loop m times, and in each iteration, obtaining at least two frames of the video stream according to one unexamined frame resolution candidate and calculating the correlation between the obtained frames, wherein m represents the quantity of frame resolution candidates; determining the best frame resolution from the frame resolution candidates according to the calculated correlations; and outputting the best frame resolution, thereby enabling a video decoder to segment the video stream into frames according to the best frame resolution and decode the segmented frames.
