Old description:
> Summary of the bug:
>
> All versions of compiled ffmpeg 5.0 on Ubuntu 20.04 now produce a
> segfault on completion of any file using hevc_nvenc encode. This does
> not happen in any ffmpeg version before version 5.0.
>
> Used release 5.0, then updated to release N-106467-ge301a24fa1. Same
> issue. Have to revert to a compiled version of 4.4.1 to avoid this
> error.
>
> Commands plus gdb and valgrind output are below. The problem seems to be
> between ffmpeg/hevc_nvenc and the nvidia drivers. Sample ffmpeg log
> output is attached.
