Comment (by John Dury):
I added "-extra_sei 0" and tested with the gyan 08/01/2021 binaries and it
works! So happy. Once the 495 driver goes GA, I will try it and update but
at least this is a working woraround for now with the latest windows
binaries. So helpful. Thanks much.

> Yes, that is the case with logs in .rar. The GPU stops encoding after a
while. But on the other hand we bisected it (if you did not get it, my
problem is different from his, it is -bf -1 regression due to some strange
SEI in the very start of the sample) it is either
