Ladies and gentlemen, ask a question,
I want to implement using QAudioRecorder recording function,
The following code, write a Demo, can run in the ubuntu, after cross-compilation can also run the development board,
Voice file directory under the/workspace,
So simple code that can be generated under ubuntu y111. Wav,
In the development board no this file


#include
#include
#include
#include
Int main (int arg c, char * argv [])
{
QCoreApplication a (arg c, argv);

QAudioRecorder * m_pAudioRecorder=new QAudioRecorder ();
QString fileName="/workspace/y111";
QDebug () & lt; & lt;" FileName: "& lt; M_pAudioRecorder - & gt; SetOutputLocation (QUrl: : fromLocalFile (fileName));
M_pAudioRecorder - & gt; Record ();


Return a.e xec ();
}
Hope bosses to give directions, do not understand why, thank you very much

CodePudding user response:

Didn't abnormal running out, is not to come out the file

CodePudding user response:

I associated connect (m_pAudioRecorder, SIGNAL (error (QMediaRecorder: : error)), this, SLOT (displayErrorMessage ()));
To run a hint:
Error: "No input device available."
Is this reason caused no generated file?
Because the development board audio driver seemed to haven't do,
