In addition to the requests said by cold_arctus, it seems that you have some kind of problem with you video card, I can read some kind of error.
d3d11: CreateDXGIFactory2(...) not found, fallbacking to CreateDXGIFactory1(...).
d3d11: D3D_FEATURE_LEVEL_11_1 not-recognized (only 11.0 runtime installed?)

Dedicated video D3D11 device creation failed (error: 0x80004005). This device is used specifically for video decoding, we will use software video decoding instead.
Probably this is the root cause of the issue, moreover which kind of Windows system do you have? Win10, Win7, Win8?
EDIT: you can also try to open device manager and disable temporarely your video card and see what it does. if it plays fine, the problem could be the video card, if the problem persists, the problem is somewhere else
EDIT2: I have checked better your log and you have bonjour installed:
C:\Program Files (x86)\Bonjour\mdnsNSP.dll please uninstall it
