NVDEC SEI/MPEG User Data

Does NVDEC provide the associated SEI (h264) or user data (mpeg2) for a frame when using CUvideoparser? I tried parsing _CUVIDPICPARAMS->pBitstreamData in the HandlePictureDecode callback but I didn’t find anything.

CUvideoparser is a very simple class. As mentioned in the documentation, for any advanced applications, recommend that you develop your own parser.
