Abstract
The present application relates to decoding a video stream on a client device. A client application on the client device calls a decoding function implemented by a media player library, which includes a further call to a decoding function implemented by an operating system of the client device, and is modified to include a determination as to whether the video stream is encoded using a multi-layer coding scheme. If so, the video stream is processed to extract a base stream and an enhancement stream, the base stream is decoded using the further call to the decoding function implemented by the operating system, the encoded enhancement stream is decoded, the decoded enhancement stream is applied to the decoded base stream to generate decoded video stream data, and the decoded video stream data is returned to the decoding function implemented by the media player library.
