A set of video monitoring MFC procedures, play functionality is encapsulated to the bottom and is stable and available, but in order to customer demand encapsulates a set of OCX code to web call,
All other functions are no problem, but when playing video cannot receive voice that is why, ocx with MFC program final tone will have the same interface, why will appear this problem, I have a small white, seek guidance!!!!!!!!!!

Don't have access to sound is what mean? Didn't receive audio data is normal, but there is no sound? Can make sure the computer can play sound out, like a song in baidu music web site

Computer can play music, baidu can get camera video, have a picture but no sound, with MFC program calls the interface is good, but in the OCX will appear this kind of circumstance, the function parameters are almost the same, the concrete in the underlying implementation, also do not need a callback upper processing, so wonder, and no way to enter the underlying reasons
