VideoView black flash before and after playing

Question

I have a VideoView which I want to use to play a movieclip. I use it like this to play it and it works.

VideoView vv = new VideoView(this);
vv.setVideoURI(Ur         


        

Answer 1

Another solution that might work for people who are searching for this question:

In my case, the video was a resource in the app (that is, I knew everything about it and it wasn't going to change) and its last 500 ms were the same frame, so I ended up doing the following:

mVideoView.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.splash));
mVideoView.start();

findViewById(android.R.id.content).postDelayed(new WaitForSplashScreenToFinish(), mVideoView.getDuration() - 1000);

and the referenced class is:

private class WaitForSplashScreenToFinish implements Runnable {
    @Override
    public void run() {
        if (mVideoView.isPlaying() && mVideoView.getCurrentPosition() >= mVideoView.getDuration() - 500) {
            mVideoView.pause();

            // Now do something else, like changing activity
        } else {
            findViewById(android.R.id.content).postDelayed(this, 100);
        }
    }
}

Explanation: Immediately after starting the video I create a Runnable and postDelayed it to the root view (android.R.id.content) to the duration of the video, minus the length at which I'm willing to pause the video (and a generous buffer, because postDelayed isn't guaranteed to play exactly after the requested time)

Then, the runnable checks if the video arrived at its pause-time, if so it pauses it and does whatever else we want it to do. If it doesn't, it runs postDelayed again with itself, for a shortened time (100 ms in my case, but could be shorter)

Granted, this is far from being an ideal solution, but it might help someone with a specific problem similar to the one that stumbled me for half a day :)

I know it's old question but if you can add some code to MediaPlayer listeners there is very simple answer. It turned out that setBackgroundColor for VideoView changes the foreground color ( https://groups.google.com/forum/?fromgroups=#!topic/android-developers/B8CEC64qYhQ ).
So the only thing you have to do is switching between setBackgroundColor(Color.WHITE) and setBackgroundColor(Color.TRANSPARENT).

i had the same problem and white instead of black was ok for me.. i tried all of solutions above i came up with the following

vv.setBackgroundColor(Color.WHITE);
vv.postDelayed(new Runnable() {
                @Override
                public void run() {
                    vv.setVideoURI(videoUri);
                }
            }, 100);
vv.postDelayed(new Runnable() {
                @Override
                public void run() {
                    vv.setBackgroundColor(Color.TRANSPARENT);
                }
            }, 300);
            vv.requestFocus();
            vv.start();

and delayed my video 400 ms start fading from white works like a charm for me

Answer 4

I ended up having to do something very similar to @tommyd to avoid the black surfaceView flash at the beginning and end of my videos. However, I found that setting/nulling the background drawable for the videoView was not occurring instantly on many phones. There could be about a half-second delay between my call to set the background and when it was actually displayed.

What I ended up doing was creating a custom SurfaceView that showed a single, solid color, then overlayed this on top of the VideoView and made use of SurfaceView.setZOrderMediaOverlay().

My custom SurfaceView was heavily informed by: http://android-er.blogspot.com/2010/05/android-surfaceview.html

public class SolidSurfaceView extends SurfaceView implements SurfaceHolder.Callback {

    private static final String TAG = SolidSurfaceView.class.getSimpleName();

    private SolidSurfaceThread mThread;
    private boolean mSurfaceIsValid;
    private int mColor;

    public SolidSurfaceView(Context context) {
        super(context);
        init();
    }

    public SolidSurfaceView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public SolidSurfaceView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    private void init() {
        Log.verbose(TAG, "init");

        getHolder().addCallback(this);
        setZOrderMediaOverlay(true);
    }

    public void setColor(int color) {
        mColor = color;
        invalidate();
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        Log.verbose(TAG, "surfaceCreated");

        mSurfaceIsValid = true;

        mThread = new SolidSurfaceThread(getHolder(), this);
        mThread.setRunning(true);
        mThread.start();
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        Log.verbose(TAG, "surfaceDestroyed");
        mSurfaceIsValid = false;

        boolean retry = true;
        mThread.setRunning(false);
        while (retry) {
            try {
                mThread.join();
                retry = false;
            }
            catch (InterruptedException e) {
                Log.warning(TAG, "Thread join interrupted");
            }
        }
        mThread = null;
    }

    @Override
    protected void onDraw(Canvas canvas) {
        if ( ! mSurfaceIsValid) {
            return;
        }

        canvas.drawColor(mColor);
    }

    private static class SolidSurfaceThread extends Thread {

        private final SurfaceHolder mSurfaceHolder;
        private final SolidSurfaceView mSurfaceView;
        private boolean mIsRunning;

        public SolidSurfaceThread(SurfaceHolder surfaceHolder, SolidSurfaceView surfaceView) {
            mSurfaceHolder = surfaceHolder;
            mSurfaceView = surfaceView;
        }

        public void setRunning(boolean running) {
            mIsRunning = running;
        }

        @Override
        public void run() {
            while (mIsRunning) {
                Canvas c = null;
                try {
                    c = mSurfaceHolder.lockCanvas(null);
                    synchronized (mSurfaceHolder) {
                        mSurfaceView.onDraw(c);
                    }
                }
                finally {
                    // do this in a finally so that if an exception is thrown
                    // during the above, we don't leave the Surface in an
                    // inconsistent state
                    if (c != null) {
                        mSurfaceHolder.unlockCanvasAndPost(c);
                    }
                }
            }
        }
    }
}

And in the parent activity that hosts the views:

    mVideoView = (VideoView)findViewById(R.id.video_view);
    mVideoMask = (SolidSurfaceView)findViewById(R.id.video_mask);
    mVideoMask.setColor(Color.BLUE);

You can then do things like mVideoMask.setVisibility(View.GONE) to hide the mask or mVideoMask.setVisibility(View.VISIBLE) to show the mask (and hide the black-screened VideoView).

In my experiments on various phones, this method provided very fast showing/hiding of the video mask, as opposed to setting/nulling the background.

here is simple trick

check the condition media player.getCurrentPosition == 0 in on prepared listener of video view ,black screen will appear when position is zero so display an image untill the video will load

mycode:

mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(final MediaPlayer mediaPlayer) {
                mVideoView.start();


                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {

                        while (mediaPlayer.isPlaying()) {
                            Log.d("MainActivity", "position " + mediaPlayer.getCurrentPosition());
                            if (mediaPlayer.getCurrentPosition() == 0) {
                                videoStillImageView.setVisibility(View.VISIBLE);
                            } else {
                                videoStillImageView.setVisibility(View.GONE);


                                break;
                            }
                        }

                    }
                });
            }
        }
    });

That flash comes from changing the current content view to another one. You could try adding a VideoView to your layout xml file then referencing it with (VideoView) findViewById(R.id.vid); instead of new VideoView(this); and setting the content view to that layout.
