Comment (by John Dury):
I thought my original post had all of the relevant information including
the failure but it kept timing out when trying to post so maybe it did not
go through correctly.
The error I am getting is:
[hevc_nvenc @ 0000001d5df021c0] Failed locking bitstream buffer: not
enough buffer (14): .39x
video encoding failed: Buffer too small
This is easily reproduced when using the same MKV file. It has happened on
several others also. There is no other GPU activity happening when the
error occurs. I have tried this on two different machines with two
different NVIDIA GPUs, both with their latest drivers. When regressing
build levels it appears to not happen. I am testing older versions of
gyan.dev builds now and will post results once I narrow down where the bug
started.
