Abstract
In various respects, hardware-accelerated decoding is adapted for decoding of video that has been encoded using scalable video coding. For example, for a given picture to be decoded, a host decoder determines whether a corresponding base picture will be stored for use as a reference picture. If so, the host decoder directs decoding with an accelerator such that the some of the same decoding operations can be used for the given picture and the reference base picture. Or, as another example, the host decoder groups encoded data associated with a given layer representation in buffers. The host decoder provides the encoded data for the layer to the accelerator. The host decoder repeats the process layer-after-layer in the order that layers appear in the bitstream, according to a defined call pattern for an acceleration interface, which helps the accelerator determine the layers with which buffers are associated.
