How to pack OGG audio file to RIFF container?

I have an ogg audio file and some information which is saved as sequence of bytes. I need to pack this audio and information in a single container such as RIFF开发者_开发百科 or something else. I'm searching solutions which can be written under .NET.

Ogg is a container format. What you perhaps will want is either use some Ogg format tools to attach your data directly to existing file, or re-stream the data into different container format where you have tools to attach your data to.

The formats might be WAV/RIFF, Matroska, MP4. It also perhaps depends what is exactly this additional data, more like a thumbnail, or additional stream (user comments with timestamps etc).

A popular framework for such manipulation in .NET is DirectShow.NET library, but as you clarify your need, you might end up using a different tool.

                IntPtr format = dr.ReadFormat();
                WaveFormat waveFormat = AudioCompressionManager.GetWaveFormat(format);
                IntPtr formatOgg = AudioCompressionManager.GetCompatibleFormat(format, oggFormatTag);
                using (WaveWriter ww = new WaveWriter(File.Create(fileName + ".wav"),
                    AudioCompressionManager.FormatBytes(formatOgg)))
                {
                    AudioCompressionManager.Convert(dr, ww, true);
                }
            }
