Raw data as InputStream

[seijikun]

Is it possible to use raw data without a container (like pcm for raw audio) as input at the moment? What I got:

var commandFactory = CommandFactory.Create();
var cmd = commandFactory.CreateOutputCommand();
var inSettings = SettingsCollection.ForInput(new FormatInput("u16le"), new SampleRate(44100));
var mp3Settings = SettingsCollection.ForOutput(new BitRateAudio(Hudl.FFmpeg.Enums.AudioBitRateType.Mp3Cd));

cmd.AddInput("input.raw", inSettings);
cmd.To<Mp3>(mp3Settings);
commandFactory.Render();

But, obviously, since the file extension is not registered, I get a:

System.InvalidOperationException: Cannot derive resource type from path provided.

@seijikun it's not currently possible with the containers available. However if you were to implement a Raw container it would allow you to as long as ffmpeg supports it. implimentation would look like the following:

    [ContainsStream(Type = typeof(AudioStream))]
    [ContainsStream(Type = typeof(VideoStream))]
    public class Raw : BaseContainer
    {
        private const string FileFormat = ".raw";

        public Raw()
            : base(FileFormat)
        {
        }

        protected override IContainer Clone()
        {
            return new Raw();
        }
    }

As a side note, if you would like to contribute to the ffmpeg project and add this in, I would not be opposed to merging in the next release

The system as it is at the moment has not been designed with the possibility of working indipendently of the file-extension at the moment, right?

@seijikun correct
