I'm building a chrome extension that captures mic + screen + screen audio with recordrtc.
Everything is working on Windows, but it seems recording screen audio is not allowed on Mac.
Is there a way to get around this?

Issue is as follows:
ChromeOS v98 onwards (maybe earlier)
In Google Slides, insert a YouTube video. Cast to a screen, audio only plays on the chromebook not the tv you are casting to
Windows laptop with up to date chrome, casting via chromecast does same thing
ChromeOS v89 is ok
Webpage with an embedded YouTube video is fine, as is casting directly from YouTube
I compile and run QT5 example from here
https://doc.qt.io/qt-5/qtmultimedia-multimedia-audioinput-example.html
On other PC it runs just fine, but on my current PC Windows 10 seems don't allow me to use microphone.
I am double check and mic works fine in skype and other apps.
When i run example it show me all my mics:
as you can see, it detects all mics in system.
But when it starts or when i change mic from list i have this errors in debug, and mic did not work and program did not show any activity:
QAudioInput: failed to open audio device
QAudioInput: failed to open audio device
QObject::connect(QIODevice, Unknown): invalid nullptr parameter
QAudioInput: failed to open audio device
QAudioInput: failed to open audio device
QObject::connect(QIODevice, Unknown): invalid nullptr parameter
I found cause - Kaspersky KES 11 component - Intrusion detection.
After i disable it microphone begins works just fine. So if you use this antivirus just disable this component when you develop apps on qt5.
Even if you add program to group "trusted", when recompile program you need to regroup it again, because it crc changed each time you compile program.
I have a sony xperia E3 (D2203) I can build the demo for google cardboard and load the apk in the phone. When I open it it does starts, I see a menu with [reset] [recenter] [VR mode]
But the movement tracking is not working.
There is also a settings icon, when I click it leads to the cadboard app in google Play store. and In there I find out that my device is not compatible with it.
Can I work with this phone without this configuration app ?
Google Cardboard needs a built-in gyroscope to accurately track movements. Sony D2203 doesn't have this hardware, so it won't be much fun playing with Cardboard.
i am not able to play the audio file onclick of a button.
here is the code i got from the xdk website.
function audioBtn()
{
// play the sound
intel.xdk.player.playSound("sounds/anything.wav");
}
the audio location is:
C:\Users\abc\Documents\pqr\www\sounds\anything.wav
Thanks in advance....
Intel XDK Emulator doesn't support playing audio files using the intel.xdk Player object, but this does work within the Intel App Preview mobile app for testing by scanning the QR Code under the Test tab.
For example, you can play audio files (supported by your platform of course) within your application in App Preview or on device as follows
intel.xdk.player.playSound(intel.xdk.webRoot + "sounds/anything.wav");
intel.xdk.webroot contains the path for the www/ directory.
I am trying to create a mobile website and want to be able to play/stream audio files.I have tried html5's audio tag and tried testing it on opera mobile 10 simulator but it does not work. I have lots of audio files and the audio should be auto played.
sidenote:
Also, i need to test my website for android and iphone mobile phones. I am downloading android emulator for windows. I tried searching for iphone emulator for windows but there are none...
Phone emulators aren't always a good indicator as they do not usually have a media player installed. The best way to test is to find someone with an actual Andriod / Blackberry / iPhone.
You should try the same HTML5 code with an actual phone. Note that Opera Mobile 10 does not have support for the video/audio tag. If you're interested in streaming to mobiles without HTML5, you should check this FAQ entry for more information.
