MediaFoundationReader can do this with some video files, but you'll probably get more comprehensive format coverage with ffmpeg
Here is an example of how I have used MediaFoundationReader in C#. However, this does require that the proper codec to read the video is already installed on the computer. If that assumption cannot be made, then ffmpeg may be your only option.
// convert the video's audio track to Wave audio data
// this only works if the proper video codec is installed
using (MemoryStream audioStream = new MemoryStream())
{
using (MediaFoundationReader mediaReader = new MediaFoundationReader( [VIDEO FILE PATH HERE] ))
{
if (mediaReader.CanRead)
{
// move to the beginning of the mediaReader stream
mediaReader.Seek(0, SeekOrigin.Begin);
// convert the audio track to Wave data and save to audioStream
WaveFileWriter.WriteWavFileToStream(audioStream, mediaReader);
audioStream.Seek(0, SeekOrigin.Begin);
}
}
}
Is it possible to extract audio in wav format from any video files just with naudio ? Currently i am using ffmpeg, but i just want to use it with naudio only.
