C-Werk allows simultaneous decoding with Intel Quick Sync Video and NVIDIA NVDEC chips.
In this case, NVIDIA devices will be used first for decoding. When their resources end, Intel Quick Sync Video technology will be used.
For the simultaneous decoding, it is necessary to configure the decoding with Intel Quick Sync Video (see Hardware-based decoding with Intel Quick Sync Video) and with NVIDIA NVDEC chips (see Hardware-based decoding with NVIDIA NVDEC chips).
