Code sample - Audio capture to MP3 (using LAME)

Use MP3 (LAME) format for output 

VideoCapture1.OutputFormat := Format_LAME;

VideoCapture1.OutputFormat = VisioForge_Video_Capture_5.TxVFOutputFormat.Format_LAME;

Set audio capture mode 

VideoCapture1.Mode := Mode_Audio_Capture;

VideoCapture1.Mode = VisioForge_Video_Capture_5.TxVFMode.Mode_Audio_Capture;

Start capture 

VideoCapture1.Start;

VideoCapture1.Start();
