device

I have an Android smartphone connected to my Mac using a USB cable. When running Android Studio, the following appears in the LOGCAT. These lines continually repeat, sometimes in a slightly different order. It's not clear to me what's causing this and how I can fix it... 08-09 16:17:31.554 2208-20167/?

I am new to Qt and what I am trying to do is: Create a Linux app using the Qt framework. This app displays some web pages from the Internet. I want to extend the JavaScript API to access some device and device based data, which means some devices can be controlled using JavaScript in Webkit. But how do I add some customized functions/classes to Webkit in Qt? Fortunately, there exists some documentation on this, finally: http://doc.qt.io/qt-4.8/qtwebkit-bridge.html I've done a QWebKit project in which I stablished a bridge between Javascript and my C++ code. To achieve this I used the method:

How can I autostart my application's service at device boot (with the possibility of enabling/disabling this feature)? What permissions do I have to include in AndroidManifest? Thanks this permission are use <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> In your <application> element (be sure to use a fully-qualified [or relative] class name for your BroadcastReceiver): <receiver android:name="com.example.MyBroadcastReceiver"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver> In MyBroadcastReceiver.java:

When I try the open Virtual Device, I see the same error. What can I do? That error : Emulator: warning: host doesn't support requested feature: CPUID.80000001H:ECX.abm [bit 5] I can't fix my problem :/ I asked yesterday but anyone answer it :/ Note : Virtualization Technology is enabled and KVM is OK. This error is referring to CPU feature called LZCNT. It was introduced in Intel processors since Haswell (2013) and in AMD since 2007. So if your CPU is older or to any other reason does not support LZCNT - you will get this warning. You can check if your CPU support LZCNT instruction by

So what I need is something like capture devices list. And some function to get from user on which device he wants to stream. How to do such thing with openCV in win32 C++ console application? Try using some OS functions to enumerate webcams. It might take some work, but this approach will guarantee that you get a list every time (unlike the OpenCV hack, which sometimes doesn't work, for some reason). As Martin said it's not supported in OpenCV but you could use a little trick. If that satisfies your needs, you can find out the number of cameras by successively enumerating the cameras by
