Exception when calling setDataSource(FileDescriptor) method (failed.: status=0x80000000)

I'm developing a video streaming application and I'm getting stuck when calling set setDataSource with a FileDescriptor. I want my application to play the video as it is being downloaded, so once I get a minimum number of bytes, I move those bytes to another file so it can be played in another file while it's being downloaded in the original file.

So, I check if I can start the media palyer every packet like this:

if (mediaPlayer == null) {
                    // Only create the MediaPlayer once we have the minimum
                    // buffered data
                    if (totalKbRead >= INTIAL_KB_BUFFER) {
                        try {
                            startMediaPlayer();
                        } catch (Exception e) {
                            Log.e(getClass().getName(),
                                    "Error copying buffered conent.", e);
                        }
                    }
                } else if (mediaPlayer.getDuration()
                        - mediaPlayer.getCurrentPosition() <= 1000) {
                    transferBufferToMediaPlayer();
                }
}

This is the startMediaPlayer method code:

private void startMediaPlayer() {
        try {
            File bufferedFile = new File(context.getCacheDir(), "playingMedia"
                    + (counter++) + ".dat");

            // bufferedFile is the one that'll be played
            moveFile(downloadingMediaFile, bufferedFile);

            mediaPlayer = createMediaPlayer(bufferedFile);

            mediaPlayer.start();

            playButton.setEnabled(true);
        } catch (IOException e) {
            Log.e(getClass().getName(), "Error initializing the MediaPlayer.",
                    e);
            return;
}

I move the file with the following code:

public void moveFile(File oldLocation, File newLocation) throws IOException {

        if (oldLocation.exists()) {
            BufferedInputStream reader = new BufferedInputStream(
                    new FileInputStream(oldLocation));
            BufferedOutputStream writer = new BufferedOutputStream(
                    new FileOutputStream(newLocation, false));
            try {
                byte[] buff = new byte[8192];
                int numChars;
                while ((numChars = reader.read(buff, 0, buff.length)) != -1) {
                    writer.write(buff, 0, numChars);
                }
            } catch (IOException ex) {
                throw new IOException("IOException when transferring "
                        + oldLocation.getPath() + " to "
                        + newLocation.getPath());
            } finally {
                try {
                    if (reader != null) {
                        writer.flush();
                        writer.close();
                        reader.close();
                    }
                } catch (IOException ex) {
                    Log.e(getClass().getName(),
                            "Error closing files when transferring "
                                    + oldLocation.getPath() + " to "
                                    + newLocation.getPath());
                }
            }
        } else {
            throw new IOException(
                    "Old location does not exist when transferring "
                            + oldLocation.getPath() + " to "
                            + newLocation.getPath());
        }
    }
}

And I finally create the MediaPlayer object here:

private MediaPlayer createMediaPlayer(File mediaFile) throws IOException {

        if(mediaPlayer != null){
            mediaPlayer.release();
        }

        MediaPlayer mPlayer = new MediaPlayer();
        mPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
            public boolean onError(MediaPlayer mp, int what, int extra) {
                Log.e(getClass().getName(), "Error in MediaPlayer: (" + what
                        + ") with extra (" + extra + ")");
                return false;
            }
        });

        // It appears that for security/permission reasons, it is better to pass
        // a FileDescriptor rather than a direct path to the File.
        // Also I have seen errors such as "PVMFErrNotSupported" and
        // "Prepare failed.: status=0x1" if a file path String is passed to
        // setDataSource().
        FileInputStream fis = new FileInputStream(mediaFile);

        mPlayer.reset();
        FileDescriptor fd = fis.getFD();
        mPlayer.setDataSource(fd);       // IM GETTING THE EXCEPTION HERE
        mPlayer.setDisplay(mHolder);
        mPlayer.prepare();
        return mPlayer;
    }

This is the excepction I get:

I've been the whole morning stuck here and I really find no information on that error. Some people have told me to use the file path, but I get the other exception I talk about in the comments (right over the FileInputStream creation).

I'm really lost here, any help would be very appreciated

Okay, I've arrived to the conclusion that errors like:

Prepare failed.: status=0x1 (when calling prepare() )

and

setDataSourceFD failed.: status=0x80000000 (when calling setDataSourceFD() )

have to do with the file format and probably mean that the file is incomplete, corrupted or something like that...

As I have post in this link, I've found an specific video which works fine while streaming it (though I use setDataSource, not setDataSourceFD), but it'll not work with most of the videos.

From what I have read, certain video file formats have their "header" information on the END of the file. Thus your FD must be support seek function to get the "header" from the end of the file. I suspect your input file to media player fails when it seeks to the "end" of the file.

We are working on the same issues have you gotten further?

having the same error, and having read the answer above on file format, I abandonded trying to setDataSource with my .mov file and instead created a video with my Android Telefon Camera which gave me an .mp4 file. I put this in the directory Pictures/. This worked - I cound setDataSource without errors. I hope this is useful to someone.

File mediaStorageDir = new         File(Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES),     "MyDirectoryUnderPictures");
File mediaFile_mp4_android;
mediaFile_mp4_android = new File(mediaStorageDir.getPath()
                    + File.separator
                    + "mp4_test"
                    + ".mp4"); //video taken with android camera
String filePath_mp4_android = String.valueOf(mediaFile_mp4_android);
File file_mp4_android = new File(filePath_mp4_android);
Uri contentUri = Uri.fromFile(file_mp4_android);
MediaMetadataRetriever mmr = new MediaMetadataRetriever();
mmr.setDataSource(String.valueOf(contentUri));
