I'm a trying to create a simple application in C#.NET that can generate a video file from a stream of Images and an audio file. I chooses the Splicer and its working perfectly fine with my part of code. However when I try to put an mp3 audio format it shows an ERROR:An invalid media type was specified. I scanned the Splicer forum but didn't get anything useful. Any kind of help is appreciated. Here is a simple code:
        using (ITimeline timeline = new DefaultTimeline())
        {
            IGroup audioGroup = timeline.AddAudioGroup();
            ITrack rootTrack = audioGroup.AddTrack();
            rootTrack.AddAudio("testinput.mp3");
            using (
                WindowsMediaRenderer renderer =
                    new WindowsMediaRenderer(timeline, "output.avi", WindowsMediaProfiles.LowQualityAudio))
            {
                renderer.Render();
            }
        }
