我需要像音频一样的CImage [英] I need CImage like class for audio

问题描述

我有以下代码：

I have got following code:

CImage local_image;
			CaptureWndShot(local_main_dialog->web_camera_dialog.m_hWnd,&local_image,ENGINE_WINDOWS_SIZE_CX/2,ENGINE_WINDOWS_SIZE_CY/2);

			IStream *local_stream;

			HRESULT local_create_IStream_result = CreateStreamOnHGlobal ( 0 , TRUE , &local_stream );

			HRESULT local_save_result = local_image.Save(local_stream, Gdiplus::ImageFormatJPEG);

我需要能够编译以下代码：

I need to be able to compile following code:

CAudioImage local_audio_image;
			CaptureAudioSampleShot(&local_audio_image);

			IStream *local_stream;

			HRESULT local_create_IStream_result = CreateStreamOnHGlobal ( 0 , TRUE , &local_stream );

			HRESULT local_save_result = local_audio_image.Save(local_stream, Gdiplus::ImageFormatPCM);

和

And

CAudioImage local_audio_image;
			CaptureAudioSampleShot(&local_audio_image);

			IStream *local_stream;

			HRESULT local_create_IStream_result = CreateStreamOnHGlobal ( 0 , TRUE , &local_stream );

			HRESULT local_save_result = local_audio_image.Save(local_stream, Gdiplus::ImageFormatMP3);

可能吗？



更新：



我有例如RAW PCM DATA和RAW PCM DATA的AM_MEDIA_TYPE 。

如何从RAW PCM DATA和RAW PCM DATA的AM_MEDIA_TYPE写入wav文件？
