Comment (by thunder.m):
Thank YOU for finding this bug (epsecialy for testing data!), we had
alotof crashes on our systems while decoding with cuvid and MPEG2!
I can reproduce this behavior on Nvidia GTX 960 (maxwell second gen
GM206), but it works without any problems on GTX 1060, 1070 and 1080 (we
have alotof nvidia cards).
What is very strange is that i can't reproduce this on Quadro M4000, which
is also Maxwell but GM204. So my first opinion is that affected are only
GM206 cards.
Could anyone test this sample on GTX970/980 with GM204?
Solution could be for now to switch to GTX 1050 which has also 2x faster
encoder :)
By the way i think it could be in CUDA or in NVDEC engine so driver fix
from NVIDIA is needed. It is not bug in ffmpeg itself.
