I am trying out the DEM screenCapture example with Media SDK 1.0. I built the example and ran it with the provided example configuration, it ran successfully (screen went back for a sec and came back at the beginning and at the end). I played back the recorded H.264 file and expected to see my desktop captured, but I saw nothing but black screen. I tried to changed encUsage in the configuration but it was the same. Did I miss anything?
My system is an Acer Aspire V5 with A10-5757M and running Win 8.1. The driver package version is 184.108.40.206.
