做过avi视频的大侠帮个忙

[火麒噬日]

现在有个需求就是将一系列jpg图片和ima_adpcm声音文件生成视频。
我已经找到了jpg图片转avi的代码并且做了仔细的研究。
但是将声音文件加入avi的完全的代码或者资料却始终没找到。
下面是一段介绍生成avi的代码，但我不知道声音的buffer怎么生成。

请哪位弄过这方面的高手指教一下。

[code=C/C// TestAvi.cpp : 定义控制台应用程序的入口点。

AVIStreamWrite(m_aviAudioStream,m_aviAudioFrames ,1,(LPBYTE)pBuffer,pWaveHdr->dwBytesRecorded ,AVIIF_KEYFRAME,NULL,NULL);

这句是写音频帧，但是pBuffer应该怎么填充这个我找不到相关的资料。

这个JPG转AVI好像不行吧 只支持BMP的图片

不知道你是做的？

[火麒噬日]

BMP能转，jpg就是小问题啦
