Abstract
The present invention provides a method, device and computer-readable medium of a seamless switch between resolutions based on software and hardware decoding and belongs to a field of the Internet technology. The method, device and computer-readable medium of the present invention comprise, during playing a DASH video, initializing a software decoder according to a video stream in a target encoded format received by an original decoder when it needs to switch to another resolution, at the same time the original decoder continuing to decode the video stream in an original encoded format existing in a buffer, decoding the video stream in the target encoded format using the software decoder after the video stream in the original encoded format is decoded, at the same time initializing a second hardware decoder corresponding to the target encoded format, switching to the second hardware decoder and stopping software decoding when a decoding progress of the second hardware decoder catches up with a decoding progress of the software decoder, so as to realize the seamless switch between the resolutions, avoid sticking in the process of playing the video, and improve user experience.
