NVDec is creating artifacts when decoding HEVC 10-bit streams. I have tested it with Video SDK 8.0.14 as well as my own player application (driver 385.41). This occurs for almost all of my HEVC 10-bit streams. I understand that there is an internal nVidia bug report but it has been almost 6 months with no resolution.
Test streams are available here:
Please advise progress and schedule for fixing this show-stopper NVDec bug.
the same happened to me, I fire a bug (Tue, Sep 12, 2017 at 4:29), but no response for now.
Exodus_UHD_HDR_Exodus_draft.track_1.hevc is demux from the famous demo file “Exodus_UHD_HDR_Exodus_draft.mp4” , please download.
ways to reproduce:
use NvDecodeD3D11 demo , use command, i “f:\mkv\mkv\Exodus_UHD_HDR_Exodus_draft.track_1.hevc” o “f:\mkv\mkv\cuda_test_sdk_hevc.yuv”
around frame 208， many frames mess up
download from ffmpeg
ffmpeg -hwaccel cuvid -c:v hevc_cuvid -i “E:\00069.m2ts” -c:v hevc_nvenc “f:\mkv\cuda10bitdec.mp4”
many frames mess up at the begin of output file
This appears to have been fixed in driver 387.92. Thank you nVidia!
