A method for switching decoding and rendering of a digital video stream from a first graphics processing unit (GPU) to a second GPU. The digital video stream is evaluated to determine an amount of time until a next intra-coded frame (I-frame) in the digital video stream. If the amount of time is below a threshold, decoding and rendering of the digital video stream is switched to the second GPU on the next I-frame in the digital video stream and decoding the digital video stream by the first GPU is stopped. If the amount of time is above the threshold, the digital video stream is decoded on both the first GPU and the second GPU, the rendering of the digital video stream is switched to the second GPU, and decoding the digital video stream by the first GPU is stopped. |
