我想讀取一AVI檔的內容(有VIDEO跟AUDIO兩個STREAM),並存至一個新的AVI檔中, VIDEO的部分可正常撥出,但是AUDIO只聽到"嘟嘟嘟嘟...."的聲音,確定資料都有存入, 但是聲音無法正常撥出,尋找過站上以前的文章,幾乎都是在討論VIDEO的轉換, 很少看到討論聲音部分的文章,請有經驗的前輩們指教,謝謝!! (附上程式碼供參考,這是要貼上來才整理的,compiler會過,但執行起來怪怪的,請幫我看轉存流程以及參數有無下錯即可) < class="code"> PAVIFILE *SourceFile; IAVIFile *DestFile; AVISTREAMINFO VideoStreamInfo, AudioStreamInfo; PAVISTREAM pSourceVideo, pSourceAudio; PAVISTREAM pDestVideo, pDestAudio; HRESULT hr; BITMAPINFOHEADER sBitmapInfo; WAVEFORMATEX sWaveFormat; LONG plBitSize, plWaveSize; int iVideoCount, iAudioCount; char VideoBuf[64*1024], AudioBuf[64*1024]; const char *SourceFileName = "f:\\source.avi", *DestFileName = "f:\\test.avi"; //------------------------------------------------------------------------------ AVIFileInit(); //開啟來源檔 hr = AVIFileOpen(SourceFile, SourceFileName, OF_READ, 0L); if (hr != 0){ return; } //讀取影像stream的StreamInfo與Format hr = AVIFileGetStream(*SourceFile, &pSourceVideo, streamtypeVIDEO, 0); if (hr != 0){ return; } AVIStreamInfo( pSourceVideo, &VideoStreamInfo, sizeof(VideoStreamInfo)); AVIStreamFormatSize(pSourceVideo, 0, &plBitSize); AVIStreamReadFormat(pSourceVideo, 0, &sBitmapInfo, &plBitSize); //讀取聲音stream的StreamInfo與Format hr = AVIFileGetStream(*SourceFile, &pSourceAudio, streamtypeAUDIO, 0); if (hr != 0){ return; } AVIStreamInfo( pSourceAudio, &AudioStreamInfo, sizeof(AudioStreamInfo)); AVIStreamFormatSize(pSourceAudio, 0, &plWaveSize); AVIStreamReadFormat(pSourceAudio, 0, &sWaveFormat, &plWaveSize); //------------------------------------------------------------------------------ //開啟新檔 hr = AVIFileOpen(&DestFile, DestFileName, OF_WRITE|OF_CREATE, NULL); if (hr != 0){ return; } //建立 VIDEO stream hr = AVIFileCreateStream(DestFile, &pDestVideo, &VideoStreamInfo); if (hr!=AVIERR_OK) {return;} hr = AVIStreamSetFormat(pDestVideo, 0, &sBitmapInfo, plBitSize); if (hr!=AVIERR_OK) {return;} //建立 AUDIO stream hr = AVIFileCreateStream(DestFile, &pDestAudio, &AudioStreamInfo); if (hr!=AVIERR_OK) {return;} hr = AVIStreamSetFormat(pDestAudio, 0, &sWaveFormat, plWaveSize); if (hr!=AVIERR_OK) {return;} //------------------------------------------------------------------------------ for(long lStreamSize=AVIStreamStart(pSourceVideo);lStreamSize 發表人 - gac 於 2004/09/16 19:30:13
