從FLV中提取音頻數據並注入MP3

Question

我需要從FLV中提取音頻數據，然後用C＃將它注入到MP3中。所以我正在尋找這個庫或者如何用rawdata/file結構來做到這一點。

Answer 1

看看FLVExtract。 oss flv音頻流提取器。

編輯： 感興趣的文件在Library文件夾下。要在您的項目中使用它們，請嘗試以下操作：

using (FLVFile flvFile = new FLVFile(fileName)) 
{ 
    // first param is whether or not to extract audio streams (true) 
    // second param is whether or not to extract video streams (false) 
    // third param is whether or not to extract timecodes (false) 
    // fourth param is the delegate that gets called in case of an overwrite prompt (leave null in case you want to overwrite automatically) 
    flvFile.ExtractStreams(true, false, false, null); 
}
