Hello,
1. What you were trying to accomplish:
Transcode from AVC to HEVC with NVENC.
2. The problem you encountered:
The transcoded video has seeking issues. Specifically, it does not seek
forward or backward correctly. And the video and audio do not synced
correctly (the video is only a still image while the audio continues on).
This seems to be a regression because the seeking issues do not exist with
ffmpeg version 2023-04-03-git-6941788d24-full_build-www.gyan.dev.
The seeking issues are confirmed to exist with:
ffmpeg version 2023-04-06-git-b564ad8eac-full_build-www.gyan.dev
ffmpeg version 2023-05-31-git-baa9fccf8d-full_build-www.gyan.dev
These seeking issues seem to only exist if the output is in MP4 format.
If the output is MKV format (i.e. change the output file extension to
.mkv) the there are no seeking issues.
These seeking issues seem to only exist if the input video is 23.976 FPS.
30 FPS and 60 FPS input videos do not exhibit seeking issues after
transcoded.
FFplay and PotPlayer are used to verify the seeking functionality.
3. The exact command line you were using:

Comment:
This seeking issue/regression has been resolved as of ffmpeg version
2023-06-15-git-41229ef705-full_build-www.gyan.dev.
Since there has been no response to this ticket, there is no details as to
what exactly caused the issue/regression and what was done to fix it.
Since the initial report, the graphic driver has been updated to
31.0.15.3623, but that did not seem to have any affect because even with
the new driver, the seeking issue persisted with earlier ffmpeg version:
2023-06-11-git-09621fd7d9-full_build-www.gyan.dev and 2023-06-04-git-
b1c3d81e71-full_build-www.gyan.dev.
