Abstract
The present invention provides a method, device and computer-readable medium of a seamless and dynamic switch between resolutions based on hardware decoding and belongs to a field of the internet technology. According to the method, device and computer-readable medium of the present invention, during a DASH video playback, when it needs to switch to another resolution, the original decoder continues to decode the video stream in the original encoded format that already stores in a buffer, while the video stream in the original encoded format is decoded, a second decoder corresponding to a target encoded format is initialized based on a video stream in the target encoded format received by the original decoder, and the video stream of the target encoded format is decoded by the second decoder, so as to realize the seamless switch between resolutions, avoid a jam in the process of playing the video, and improve the user experience.
