我尝试使用拼接器从图片和 MP3 创建视频。对于某些音频文件，我没有任何问题，但由于某些原因，我得到“此 Mediatype 无效。”。

这是我的代码，也许你可以帮助我

CreateVideo(@"C:\save_in_here\test.wmv", @"C:\pic\1.jpg", @"C:\mus\1.mp3");

. . .

 public void CreateVideo(string videoToCreate, string imageLoc, string tuneLoc)
    {
        if (videoToCreate.Equals(""))
        {
            MessageBox.Show("Error");
        }
        else
        {
            using (ITimeline timeline = new DefaultTimeline())
            {
                IGroup group = timeline.AddVideoGroup(32, 720, 576);
                ITrack videoTrack = group.AddTrack();
                IClip clip = videoTrack.AddImage(imageLoc, 0, 120);

                // add some audio
                ITrack audioTrack = timeline.AddAudioGroup().AddTrack();
                    IClip audio = audioTrack.AddAudio(tuneLoc, 0, 120); // ERROR?!

                // create an audio envelope effect, this will:
                // fade the audio from 0% to 100% in 1 second.
                // play at full volume until 1 second before the end of the track
                // fade back out to 0% volume
                audioTrack.AddEffect(0, 120, StandardEffects.CreateAudioEnvelope(1.0, 1.0, 1.0, 120));

                // render our slideshow out to a windows media file
                using (WindowsMediaRenderer renderer = new WindowsMediaRenderer(timeline, videoToCreate, WindowsMediaProfiles.HighQualityVideo))
                //using (AviFileRenderer renderer= new AviFileRenderer(timeline,videoToCreate))
                {
                    renderer.Render();
                }
            }
        }
    }

顺便说一句：我集成了dll并链接了它。

System.Runtime.InteropServices.COMException (0x80040200): Es wurde ein ungültiger Medientyp angegeben.

这就是我得到的完整异常错误。
