avfoundation - How do I convert a CMTime to an NSValue in Swift? -

-

I was trying to speed up the use of Aviplayer's method and CMTimes NSValues ​​, which take the form of the addBoundaryTimeObserverForTimes input. In the end, I worked in wrapping the [nsetring valued adcmtim:] in the C function and called it fast, but is there a way to do it at a faster speed?

valueWithCMTime: is the SWIFT constructor for NSValue (CMTime) :) : 

  Import CoreMedia import AVFoundation cmTime = CMTimeMake (10, 20) cmValue = NSValue (CMTime: cmTime)

python - Strange behavior using PyQt4's 'pyqtSlot' decorator before another decorator -

-
I have a strange problem with using the QtCore.pyqtSlot decorator in front of the function decorated with a different decorator. The problem below shows this problem, it immediately provides a low QT program with a single button. When pressing a button, the following happens: (1) The signal 'signal_A' and 'signal_B' sequence are connected to method_A and method_B ​​respectively. (2) signal_A and signal_B signals are emitted. (3) The required behavior is that the method_A and method_B ​​are executed. However, it turns out that both signal_A and signal_B trigger method_A, or method_B ​​(oddly, this is nondeterministic, and different for each part of the program!). It appears to be a bug. This issue is present when PyQt4 binding is used in Qt. It is not present when using PySide (use the '-pyside' parameter to verify) I have seen both problems in Python 2 and 3, and both in Windows and Linux This issue is related to the insertion of a decorator be...

c# - UnhandledExceptionMode.ThrowException for AppDomain.UnhandledException -

I want to set unhandledExceptionMode.ThrowException for current AppDomain and not only for application threads. An exception from the second thread should also be handled by my current Donan_Unimated exception handler. Is it possible? Here's my code: Fixed class program {/// & lt; Summary & gt; Main entry point for the application /// & lt; / Summary & gt; [STAThread] static zero major () {applications Set unhandled exception mode (unwanted exception. Throws up); AppDomain.CurrentDomain.UnhandledException + = New UnrestrictedExceptionEndception (CurrentDomain_UnhandledException); Application.EnableVisualStyles (); Application.SetCompatibleTextRenderingDefault (wrong); Application.Run (New Form 1 ()); } Static Zero CurrentDomain_UnhandledException (Object Sender, UnhandledExceptionEventArgs E) {File.AppendAllText ("Log.txt", (Exception) e.ExceptionObject). Message + environment. Newline); }} Maybe you search for the behavior provided by Applic...

When I try to kill with a command prompt, I get the message: "Access denied" I tried to run as my app administrator and the process was killed. How can I not always use "Run as administrator"?
