所以我的资源文件夹中有一个小的音频文件,我想打开一个InputStream写入缓冲区,然后写入临时文件,然后打开MediaPlayer播放该临时文件.问题是,当媒体播放器点击mp.Prepare()时,它不播放并且永远不会到达祝词.有没有人曾经这样做过？

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    InputStream str;

    try {

        str = this.getAssets().open("onestop.mid");
        Toast.makeText(this, "Successful Input Stream Opened.", Toast.LENGTH_SHORT).show();
        takeInputStream(str);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}//end on create

public void takeInputStream(InputStream stream) throws IOException
{
    //fileBeingBuffered = (FileInputStream) stream;
    //Toast.makeText(this, "sucessful stream conversion.", Toast.LENGTH_SHORT).show();
    try
    {
        convertedFile = File.createTempFile("convertedFile", ".dat", getDir("filez", 0));
        Toast.makeText(this, "Successful file and folder creation.", Toast.LENGTH_SHORT).show();

        out = new FileOutputStream(convertedFile);
        Toast.makeText(this, "Success out set as output stream.", Toast.LENGTH_SHORT).show(); …

我正在开发一个项目,我需要从IPCamera中读取输入流.我可以通过rtsp url获取此信息.

显示IPCamera流.我可以通过使用 -

    videoView = (VideoView) this.findViewById(R.id.videoView1);
    MediaController mc = new MediaController(this);
    videoView.setMediaController(mc);
    videoView.setVideoURI(Uri.parse("rtsp://xxxxxxxx/camera1"));
    videoView.requestFocus();

现在我想将此流记录到MP4文件中.同样我使用mediarecorder.Here我被卡住了.

    MediaRecorder mediaRecorder = new MediaRecorder();
    //mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
    mediaRecorder.setOutputFile("rtsp://xxxxxxxxx/camera1");
    try {
        mediaRecorder.prepare();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    mediaRecorder.start();

谢谢
