As you can see, both threads are locked.

There is a bug in Tegra drivers that causes a deadlock when using shared contexts. More info:

I'm closing it because it's not directly related with this library, but with an Intel's tutorial about using this library: https://software.intel.com/en-us/articles/intel-inde-media-pack-for-android-tutorials-video-capturing-for-unity3d-applications
