It does not seem to be heavily connected to my stuff.
However on the first glance it looks strange that Direct3DCreate9 is called during decoding. The initialization should be done beforehand.

I got the same error,the graphic card is Nvida GT720 ,when switch play and destroy the video the error is absolutely reproducible。
I also tryed intel hd4600 the same error too.upgrade the driver is not help,So Can you have some attentiob to this question

it happed in nvd card

[ArtistZhou]

Yes, Nvida GT720 ,Nvida gtx1650 ,gtx 750 have this problem all
I found this
For NVIDIA, we wait to avoid those GPUs with Feature Set E
for HEVC decoding, since that's hybrid. It appears that Kepler GPUs
also had some hybrid decode support (per DXVA2 Checker) so we'll
blacklist those too.
