• Not sure what function you’re calling, but this HResult is actually not an error. The function is returning this result code to tell you it had filled it’s buffer but there is still more to read. Just continue reading and it will
  be fine.

  If the function you’re calling is not implemented to be called in loop to the completion, there could be bug in the library.

  Finally, this is not a support forum for 3rd party libraries. Try file an issue
  on their Github site
  and see if they can help you identify the problem.

• Here is my sample code.. On our testing server its working fine. but on client server its not working. Throwing same exception «More data is available. (Exception from HRESULT: 0x800700EA)»

  same code is working for converting WAV file to MP3 but not for M4A to MP3.

  try
              {
                  using (var reader = new AudioFileReader(SourceFilename))
                  {
                      using (var writer = new LameMP3FileWriter(TargetFilename, reader.WaveFormat, LAMEPreset.STANDARD))

• Try obtaining support at
  their site. I think the server may not have codec installed for M4A format, or there’s possibly a bug in
  MediaFoundationReader.

  If checked it’s not codec issue, for temporary fix, try to see if there is .CopyTo() variant that allows you to supply buffer size, and if yes, give it big value (ideally big enough to store your audio file in one go if your M4A files are small).

  Alternatively, do the copy with AudioFileReader.Read() and LameMP3FileWriter.Write() yourself.

  EDIT: Most probably codec issue.
  Servers does not come with those audio codec.

• i have already install all codec on server. If i try to Convert a .wav file, code work fine. but when i pass it .m4a file, its throw an exception.

  can you post an example code using «AudioFileReader.Read() and LameMP3FileWriter.Write()«

  Thanks in advance.

• Much like the
  ordinary file copy operation (except you use AudioFileReader and LameMP3FileWriter instead of BinaryReader and BinaryWriter)

                   using (var reader = new AudioFileReader(SourceFilename))
                   using (var writer = new LameMP3FileWriter(TargetFilename, reader.WaveFormat, LAMEPreset.STANDARD))
                   {
                       byte[] buffer = new byte[1024];
                       int bytesRead;
  
                       while ((bytesRead = reader.Read(buffer, 0, 1024)) > 0)
                       {
                           writer.Write(buffer, 0, bytesRead);
                       }
  
                       status = true;
                   }

  Since you’re using using, the object close and disposal code for writer is redundant.

• I have tried my code on total 3 server. Except One server (our testing server), both other two server (client server) throwing same error. I am really stuck with this error. What kind of More data and where is that data Available.

  Suggest me any new new Library for converting .m4a files to mp3.

  Thanks Advance.
