I am developing a live application, encoding some videos. I want to preview the reconstruction of the encoded data.
Using NvDec to decode the bitstream will cause some latency.
Is there an API to obtain the reconstruction result of the NvEnc?

Seems it is supported in Video Codec SDK 12.1. I will try it out.
