A couple of month before I have evaluated
the USB camera with Raspberry Pi 2 on Windows 10 IoT Core and got the
unacceptable results on camera preview rendering performance. Here is the blog
post Windows
10 IoT Core – Sample Camera applications. Even though the performance is
poor, I was talking about the advantage of UWP application on Windows 10 IoT
Core.
Recently Microsoft added DragonBoard 410c
in the list of
hardware supported for Windows 10 IoT Core. Good news is, the binary
released for this board support driver for its inbuilt WiFi module and a Direct
X driver for its GPU. I was very curious to check the graphics performance
of the DirectX driver using the same USB Camera (e-cam51_USB) and UWP application. Yes. It is
fantastic, able to see the camera preview rendering at 30 fps for 640x480
resolution frame, scaled up to the full HD monitor. Also able to perform the
video encoding with MP4 with the reasonable performance.
