but I do not get the progress bar here. all I get is the the video directly.
All help is appreciated.
Instead of dismissing the progress dialog in runOnUiThread, dismiss it in the onPreparedListener:
mVideoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer arg0) {
dialog.dismiss();
mVideoView.start();
}
});
runOnUiThread is called right away, therefore dimissing the dialog before it can be seen. This code will keep it going until the video is ready to start.
you should use an AsyncTask to do that. have a look on this page. it gives you detailed information on how to do what you want.
You'll have to move away from the synchronous MediaPlayer calls to do this. The MediaPlayer has series of player state change callbacks such as onPreparedListener which you'll need to make use of to determine when to display your dialog.
What you are experiencing is due to the fact that, although you are putting work to the uiThread, you are basically putting all your work to the uiThread.
The call:
mVideoView.setVideoPath(getDataSource(path));
is going on the uiThread (seemingly). You need to use the async listeners to avoid having to build those facilities for yourself.

I am trying to make an application which should first record the user's voice and then calculate different things (e.g. spectrum) from the recorded file. I can't play the recorded file (I can't find that file - does it even record?). Here is my code:
package com.example.annik.puhesovellus;
import android.media.MediaPlayer;
import android.media.MediaRecorder;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;

import java.io.IOException;
public class DisplayAanitysIkkuna extends AppCompatActivity {
private String mFileName;
private MediaRecorder mRecorder;
private MediaPlayer mPlayer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_aanitys_ikkuna);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
mFileName = Environment.getExternalStorageDirectory()+"/audiorecorder.3gpp";
}
public void ButtonTapped(View view) {
switch(view.getId()) {
case R.id.start:
try {
beginRecording();
}catch(Exception e){
e.printStackTrace();
}
break;
case R.id.stop:
try {
stopRecording();
}catch(Exception e) {

}
break;

}catch(Exception e) {
e.printStackTrace();
}
break;
case R.id.stopPlaying:
try {
stopPlaying();
}catch(Exception e) {
e.printStackTrace();
}
break;
}
}
private void stopPlaying() {
mPlayer.release();
mPlayer = null;
}
private void playRecording() throws Exception{
ditchMediaPlayer();
MediaPlayer mPlayer = MediaPlayer.create(this, Uri.parse(mFileName));
mPlayer.start();
}
private void ditchMediaPlayer() {
if(mPlayer != null) {
try {
mPlayer.release();
}catch(Exception e) {
e.printStackTrace();
}
}
}
private void beginRecording() throws IOException {
ditchMediaRecorder();
File outFile = new File(mFileName);
if(outFile.exists()) {
outFile.delete();
}
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mRecorder.setOutputFile(mFileName);
mRecorder.prepare();
mRecorder.start();
}
private void ditchMediaRecorder() {
if(mRecorder != null) {
mRecorder.release();
}
}
private void stopRecording() {
if(mRecorder != null) {
mRecorder.stop();
}
}
}
And I know the indents are not correct because I pasted the code badly... Do you have any ideas why this code doesn't work? It gives two errors: "Should have subtitle controller already set" but I read that I don't need to mind that and "QCMediaPlayer mediaplayer NOT present" and I read that this means that my platform doesn't support QCMediaPlayer..?
Does this code record a file and it just can't play it or does it fail to record a file? How can I record user voice and process the saved file?
I believe that problem is in playRecording(). When you type MediaPlayer mPlayer = ... it creates a new variable with scope inside that method. You are not using your class MediaPlayer variable. Try to change
MediaPlayer mPlayer = MediaPlayer.create(this, Uri.parse(mFileName));
to
mPlayer = MediaPlayer.create(this, Uri.parse(mFileName));

You can get a video frame with MediaMetadataRetriever. The basic usage is as follows.
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
// Set data source to retriever.
// From your code, you might want to use your 'String path' here.
retriever.setDataSource(yourPath);
// Get a frame in Bitmap by specifying time.
// Be aware that the parameter must be in "microseconds", not milliseconds.
Bitmap bitmap = retriever.getFrameAtTime(timeInMicroSeconds);
// Do something with your bitmap.
You might want to use FFmpegMediaMetadataRetriever for better performance.
I too have searched the same for some days and finally i came across opencv library through that we can able to read the frames from a live video and do the operations accordingly.
I have did successfully and keeping the project in github for your reference.

Let me know if you still need a help.

The problem might be with the video encoding. Android Froyo and Gingerbread doesn't support H264 formats other than "Baseline" H264. So if your video is Mp4 & H264 encoded make sure its "AVC baseline" encoded. Use some tools like "Media info" in windows/Linux and check your video encoding. Convert the video to Baseline if possible.
An alternative workaround is to skip the Videoview and use a video play intent and redirect the playback to an app. User will be prompted to pick a player to handle the playback. Obviously if the video view cant play the file, the default player also wont be able to handle the file. you can choose some other installed player like Mx-Player which will stream the file perfectly.
Hope that solved your issue.
Try correct video url with protocol: http://www.ooklnet.com/files/368/368007/video.mp4

I took a sample tutorial from http://davanum.wordpress.com/2009/12/04/android-%E2%80%93-videomusic-player-sample-take-2/
and further enhancing it to implement seek bar. I have added the code but seek bar doesn't move as the video progresses. Am I doing anything wrong? I am new to android programming.
