Is it very strange? How can the E voice use WMP to play and send information? ? As far as I know the function of the WMP client does not provide media transmission.
I didn't find the entire WMP SDK did not find information about Microsoft to provide multimedia data flow in WMP, unlike DirectShow.
I have been working for a long time, I want to think about the current location through IWMPControls get_currentposition, then read the current frame and send it from the local file.
