Hi to all,
I would put in a separate thread the code to encode in an mp3 file some audio datas.

Qt Code: 
  1. #include <QThread>
  2.  
  3. class WaveEncoder : public QThread
  4. {
  5. public:
  6. 	WaveEncoder( QString& sndName, QString& outputDir, bool bg, SoundData*, WaveDisplay*, QObject* parent = 0 );
  7. 	~WaveEncoder();
  8.  
  9. protected:
  10. 	void run();
  11.  
  12. private:
  13. 	int EncodeToMp3();
  14. 	void ProcessTitle( QString&, QString& );
  15. 	bool LoadBgSound();
  16.  
  17. 	SoundData* m_wave;
  18. 	WaveDisplay* m_WaveDisplay;
  19.  
  20. 	QString m_SoundName;
  21. 	QString m_OutputDir;
  22.  
  23. 	/* for the background audio */
  24. 	signed short* inbuffer;
  25. 	FMOD::Sound* bgSound;
  26. 	unsigned int bgBytes;    // length in Bytes
  27. 	unsigned int bgSamples;  // length in PCM
  28. 	/* to call sound::lock() */
  29. 	void* ptr1;
  30. 	void* ptr2;
  31. 	unsigned int len1;
  32. 	unsigned int len2;
  33.  
  34. 	bool m_bgAudio;
  35. };
  36.  
  37. #endif  //__WAVEENCODER_H__

the ctor
Qt Code: 
  1. WaveEncoder::WaveEncoder( QString& sndName, 
  2. 						  QString& outputDir, 
  3. 						  bool bg, 
  4. 						  SoundData* sndData, 
  5. 						  WaveDisplay* waveDisp, 
  6. 						  QObject* parent ) 
  7. 						  : QThread(parent)
  8. {
  9. 	m_SoundName = sndName;
  10. 	m_OutputDir = outputDir;
  11. 	m_wave = sndData;
  12. 	m_WaveDisplay = waveDisp;
  13. }

and the run method

Qt Code: 
  1. void WaveEncoder::run()
  2. {
  3. 	EncodeToMp3();
  4. }
To copy to clipboard, switch view to plain text mode 

Here is where I create and run the thread:

Qt Code: 
  1. void WaveWidget::cutSound()
  2. {
  3. 	WaveEncoder encoder(m_SoundName, m_outputDir, false, m_wave, m_WaveDisplay);
  4. 	encoder.start();
  5. }
To copy to clipboard, switch view to plain text mode 

I get this error:
ASSERT failure in QThread::setTerminationEnabled(): Current thread was not started with QThread....
What does mean? And how can I solve this error?

Regards,
Franco
