This introduces the required definitions for HEVC decoding support with stateless VPUs. The controls associated to the HEVC slice format provide the required meta-data for decoding slices extracted from the bitstream.
This interface comes with the following limitations: * No custom quantization matrices (scaling lists); * Support for a single temporal layer only; * No slice entry point offsets support; * No conformance window support; * No VUI parameters support; * No support for SPS extensions: range, multilayer, 3d, scc, 4 bits; * No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.
