I've read that Qt Multimedia uses WMF on Windows, which already provides a few encoders natively. Are these encoders accessible through Qt yet? Is there a way to make more codecs available to QAudioRecorder on Windows? At the moment, WMF is used only for media playback features but not for recording. On Windows, QMediaRecorder uses http://msdn.microsoft.com/en-us/library/windows/desktop/dd757715(v=vs.85).aspx instead and that's why it only supports recording to pcm format. Using WMF would indeed make more codecs available but it needs to be implemented. -- Yoann Lopes Senior Software Engineer - Digia, Qt Visit us on: http://qt.digia.com
