Hello.

I try to fill QCombobox by data of audio input devices, using the following code:

    foreach( const QString& name, m_vdk->getAudioInputDeviceList() )
    {
        const int id = -1;
        id = m_vdk->getAudioInputDevice( name );
        m_ui->combo_input_devices->addItem( name, id );
    }

Calling getAudioInputDevice() invokes a crash of application with signal SIGABORT. First string of the 'backtrace report' says that cause is that "*** buffer overflow detected ***". If will comment call getAudioInputDevice() – then application will not crash.


System: Ubuntu 12.04 ( 64-bits ).

VDK:  Trial Version 1.1.0


Please, help me. =)

I check list, returned by getAudioInputDeviceList() – it's contains tree names:

"HDA Intel PCH: VT1708S Analog (hw:0,0)"
"USB2.0 PC CAMERA: USB Audio (hw:1,0)"
"sysdefault"

VDKQtEngine::getAudioInputDevice() invokes a crash with 1st and 2nd name ( "HDA Intel PCH: VT1708S Analog (hw:0,0)" and  "USB2.0 PC CAMERA: USB Audio (hw:1,0)" ), but works fine with "sysdefault" – returns '6';

Also I check list, returned by getAudioOutputDevice() – it's contains four names:

    "HDA Intel PCH: VT1708S Digital (hw:0,1)"
    "HDA Intel PCH: VT1708S HP (hw:0,2)"
    "iec958″
    "spdif"

VDKQtEngine::getAudioOutputDevice() invokes a crash with the 2nd name ( "HDA Intel PCH: VT1708S HP (hw:0,2)" ) only.

Hello grin,

the crash you mention is most certainly a bug that has already been fixed in retail version. Unfortunately the trial package has not yet been updated.

It is peculiar that the getDefaultOutputDevice does not crash for you with the first device.

If you are interested i can pm you a link where to download the trial version of 1.2RC (that supports Ubuntu 12.04)

best regards
