In Axxon Next, decoding with both Intel QSV and NVDEC is possible.

In this case, Nvidia devices are the first  to take up the  decoding job. Then, if they max out,  Intel QSV takes over and offloads Nvidia's chip.

To enable parallel decoding, do as follows:

1. Configure decoding on Intel's Quick Sync Video (see Hardware-based decoding with Intel Quick Sync Video) and on Nvidia's NVDEC (see Hardware-based decoding with Nvidia NVDEC chips).
2. Create a system variable NGP_MIXED_DECODING and set it to 1 (see Appendix 10. Creating system variable).
