One of the users had recently complained about encoding problems with HEVC encoding with WP (Weighted Prediction). This is a driver issue that has been identified, and shows up when using HEVC + WP + (PictureTimingSEI messages and or buffering period SEI messages).

Recently the PictureTiming SEI message was turned on by default in the NVENC code in ffmpeg and the issue shows up when doing HEVC encodes with WP turned on.

We have a driver fix that will come up in a later release, and users would be suggested to not enable weighted prediction with HEVC till a fixed driver version is available.
