How to convert amr files to mp3 using C#

Question

I am using NAudio MFT to convert different audio formats to MP3. Now i want to convert amr file to MP3 using Naudio MFT. But, when i given amr file as input to MFT, it has thrown following exception "Exception from HRESULT: 0xC00D36C4". Is there any way to achieve this?

My C# code:

public byte[] ConvertAMRToMP3( )
{      
  var data = new MediaFoundationReader("..\\amr\\test.amr");
  MediaFoundationEncoder.EncodeToMP3(data, "..\\test.mp3", 128000);
  ......
}

I am working on windows server 2012 64-bit platform.

Thanks in advance.

Answer 1

0xC00D36C4 is MF_E_UNSUPPORTED_BYTESTREAM_TYPE "The byte stream type of the given URL is unsupported."

There is no support for AMR in Media Foundation codecs.
