Comment (by smallishzulu):
It is not fix friend. It is only a workaround to keep gears turning
around. It will be nice if someone who is close to Nvidia reports this. It
is a problem at GPU Decoding stage related to driver. Try FFmpeg 4.2.1
with 430.x or 440.x series drivers with Cuda 10.1, the problem occurs.
There can be a change in decode API call or Nvidia messed up with the
driver.
Apart from Pascal GPUs; new generation cards (RTX) are working with 430.x
or 440.x series drivers.
Yet, there is no official announcement for 430.x or 440.x series drivers
to drop Pascal GPUs for dense transcoding (more than 2 parallel sessions
bump out the problem. Btw, not related at all with GPU limitations.)
