My laptop have two card: intel hd graphics 4600 and nvidia geforce gtx 950M
My code just convert nv12 to rgba, and it work well on intel hd graphics 4600 .
But when i change to nvidia card on graphic setting.
D3D11_MAPPED_SUBRESOURCE ms; hr = this->_d3d11_deviceCtx->Map(this->_texture_rgba_copy.Get(), 0, D3D11_MAP_READ, 0, &ms);
it crash at Map to subresource
Exception thrown at 0x00007FF8B1E4AAFB (nvwgf2umx.dll) in TestConsole.exe: 0xC0000005: Access violation reading location 0x0000000000000068.
Can someone look for something wrong in my code? Thank.
