Thanks your answer. I had searched for the following keyword:"media foundation", "protected media path", "hdcp"
But, I can't find any solution for this problem.
I have some following question:
1st, I having use the INTEL inner graphic card (its 4400 series). This graphic card are supported "Protected Media Path" and "HDCP"?
2nd, I had given the SRM data. But, why returned error? SRM data was wrong?
Thanks your kindness.
