Test scenes can not be run

[18rmt14]

I tried following the steps the README.md.(excepted step 4.I used visual studio 2017 & runtimes x64 version)
But i can not run Test 1.unity.I get errors in console:

NullReferenceException: Object reference not set to an instance of an object
CustomPipelinePlayer.Update () (at mrayGStreamerUnity-master/mrayGStreamerUnity-master/Unity/UnityTests/Assets/GStreamerUnity/Components/CustomPipelinePlayer.cs:69)

I confirmed that gstreamer was installed properly.
What do i need to do to solve this problem ?

@18rmt14, I am getting this problem of "Plugin Load Error"
While running the test scenes, its giving error

Not the exact same error but I also meet the DllNotFound error. This problem may be caused by #13. After changing the local gstreamer version from minGW to msvc, my test scene can find the DLL.

The two versions of GStreamer runtimes have different dll conventions:

• mingw uses "lib" prefix for the dlls, which leads to the error gstreamer dlls are not found.

The compiled version in this repo takes to assumption that the installed gstreamer dlls don't have such prefix.

You could also double check that by using a dependency walker, which you can test the plugin dll to check any missing dependencies:
