New Post: System.Runtime.InteropServices.COMException (0xC00D36E3): Exception from HRESULT: 0xC00D36E3

Same issue here. I tried using MediaFoundationReader to play FLAC files (I have Flac drivers installed - http://sourceforge.net/projects/mfflac/) - and the COMException brings the app down.

Here is the code I use in unit tests:

        [Test]
        public void FlacTestWithMediaFoundation()
        {
            string file = @"C:\Users\...\Track.flac";
            byte[] buffer = new byte[65536];
            using (var fileReader = new MediaFoundationReader(file))
            {
                int bytesRead;
                do
                {
                    bytesRead = fileReader.Read(buffer, 0, 65536);
                    Console.WriteLine("Read " + bytesRead);
                } while (bytesRead > 0);
            }            
        }

It reads the file to the end, then throws the exception:

   at NAudio.MediaFoundation.IMFSourceReader.ReadSample(Int32 dwStreamIndex, Int32 dwControlFlags, ref Int32 pdwActualStreamIndex, ref MF_SOURCE_READER_FLAG pdwStreamFlags, ref UInt64 pllTimestamp, ref IMFSample ppSample)
   at NAudio.Wave.MediaFoundationReader.Read(Byte[] buffer, Int32 offset, Int32 count) in c:\src\naudio-current\NAudio\Wave\WaveStreams\MediaFoundationReader.cs: line 193
   at MyApp.UnitTests.FlacTestWithMediaFoundation() in UnitTests.cs: line 60

It may be worth re-iterating that while the unit test simply fails, when I try running my app and playing a FLAC file, Windows shuts the app down, implying a non-recoverable error happens there even though I have exception handling code in the important places.
