No audio devices available on Android !!
-
Hello everyone,
the Qt 5.2 alpha is out... I didn't tried yet, so I don't know if they implemented the AudioInput and AudioOutput.
Do someone in this thread tried the AudioInput/Output with Qt 5.2 alpha ??
The problem above has been resolved ??Cheers,
Gianluca. -
We need to wait for Qt 5.2 official release to get the Multimedia support for Android devices.
-
:-( that's a really bad news !!
I cannot understand why there is still this problem.
In the page of the 5.2 features it is clearly stated that the low-latency audio was added.
http://qt-project.org/wiki/New-Features-in-Qt-5.2
At that page, near the bottom, there is the section with Android and iOS where it is been declared that the audio was supported.So, again, my question is: "What they mean for supporting low-latency audio if there is no possibility to use because we still get no devices ??"
Please, can someone involved into the Qt development answer to this question, and how they tested audio features on android and iOS without any devices available ?? -
Hello,
same problem for me (Windows 7 + Qt5.2 Beta + Android deployment on several different devices). Question for muaddib and Gianluca: what environment do you use (Linux/Windows/Mac) ? Could this bug be related to QTBUG-34275 ?
Maybe the problem does not occur on Linux/Mac ?
A simple way to show the problem is to compile the 'examples/multimedia/audiooutput' project. It works fine when compiled on desktop (audio devices appear in the QComboBox), but not on Android device. -
On Linux and Mac I cannot even build and run the audiooutput example :-(
On Mac, it seems that iOS lacks completly the multimedia module :-(
On Linux, it comply that it did not find Qt5Quick.so library ... but the audiooutput it is not a Quick application :-( -
Some news !
After struggling a bit for compile the audioinput and audiooutput on linux for android ... I successful run the two example and they found various input/output devices.So, it seems that Audio Input and Output works on Android if the app has been built from a linux machine.

well played Gianluca, on my side unfortunately I don't have Linux or Mac environment to test Android deployment.
muaddib, me neither I don't see any reference to opensl, but when I build I have this warning 'Warning: Dependency not found: C:/Qt/Qt5.2.0/5.2.0-beta1/android_armv7/plugins/audio', and in the bug I mentioned, the description talks about a problem in 'plugins/audio' for Windows, I don't know if this is linked.
I also tried yesterday's last snapshot (2013-10-24_112) and the problem is still there. -
Because it works on my linux machine, I think that you are blocked by the bug mentioned above: https://bugreports.qt-project.org/browse/QTBUG-34275
So, you don't have any alternative but wait for Qt 5.2.0 RC1 -
