[Motive API] sample code(markers) failed

[slsuperrabbit]

Hi,

I tried to run the Motive API sample code(markers), but failed with missing .dll files:
avcodec-57.dll
tbb.dll
avformat-57.dll
avutil-55.dll

OS: Windows 10 x64
VS: Visual Studio 2015 community
Motive: Motive 2.1.1 final(tracker)

How to fix it? Thanks.

Best regards.
