surfaceview

What is the best way for Camera Live filters. I am recently using GPUImage Library from Link: https://github.com/CyberAgent/android-gpuimagelibrary . Than I have found SurfaceView and GLSurfaceView. Problem is: How to apply live filter to camera using SurfaceView or GLSurfaceView. Thanks in advance. DAVE This link uses Texture View https://github.com/google/grafika/blob/master/app/src/main/java/com/android/grafika/LiveCameraActivity.java This uses surface view to play a movie..u can manipulate it for live camera https://github.com/google/grafika/blob/master/app/src/main/java/com/android

I am trying to get a HTML5 video URI when the user clicks the fullscreen button in the video control bar. According to this , the HTML5 video view in Android 4.0 is a SurfaceView, not a VideoView. Could someone tell me how to get the URI in SurfaceVideoView? This is my code. Thanks a lot. webView.setWebChromeClient(new WebChromeClient(){ @Override public void onShowCustomView(View view, CustomViewCallback callback) { super.onShowCustomView(view, callback); if (view instanceof FrameLayout){ final FrameLayout frame = (FrameLayout) view; if (frame.getFocusedChild() instanceof SurfaceView){

I am trying to make an App in which I need to use camera live feed as a background. (I know its a stupid thing to do but can't help, its a client demand). I have tried doing it using SurfaceView but no success so far. So far whatever I found on Stack Overflow are more of a guesses or directions how to do it but no real time examples or code help is out there. It would be great if someone who has done this before share a piece of code with Stack Overflow users like me. Take a look here: http://developer.android.com/guide/topics/media/camera.html There is all the code you need to make an

I have this code in a class that extends surface view and implements runnable I am able to use the class basically allows you to draw to the canvas using different colors and such. I'm trying to get a method that will allow me to save the image after it is drawn and this is the method. No matter what i do i just get a black image with nothing on it. Any ideas? I have cache drawing enabled Objective get a bitmap image from a custom SurfaceView I have exhausted options of looking at some other post on here and didn't find anything to work. Here is hoping that there is recently a new solution to

My idea is to have two surfaceViews. One surfaceView which will hold an image (say ImageSurgaceView) and second surface that lie on top of the first one which holds the annotations (say AnnotationSurfaceView) like circle, rectangle etc. Now I have to map these surface views such that the height, width are same and moreover, both the surface view should move on drag i.e share the touch events. To be precise, when I move the image up the annotations should also move up. Now, I am not sure if this is possible in android. Can any one tell or share some info on this. I don't have any implementation

I'm having trouble figuring out when surfaceDestroyed() occurs. I am trying to make my threads stop running in the surfaceDestroyed() method (of a SurfaceView) but it appears that my surface is never actually destroyed...can someone tell me when this happens? Or how to trigger it? Lumis Whenever you click return or home button and leave the activity you get: Activity onPause surfaceDestroyed and finally activity onDestroyed. When you return the surfaceView is recreated, however if you have been using static variables do drive the application, they will be often preserved and it may only seem

To run the games that I've created on Android, I've been using a GamePanel contains the methods onDraw() and onTouch(). I also have been using a GameThread class that calls onDraw() and update() repeatedly. My activity instantiates the GamePanel and my GamePanel instantiates the GameThread. My onPause() just sets the condition in the while-loop inside the thread, run, to false. My onResume() used to just set that equal to true, however that would give me a force close error ( see edit #1 ) every time I tried to resume the app. So instead to fix the problem I just re-instantiated the thread,

I am making a game and all is going well except for the game loop. I am using a SurfaceView and drawing 2D Sprites (Bitmaps). Currently the game is a ship moving through an asteroid field. The ship stays in the center of the screen and the phone is tilted in either direction to move the the asteroids (asteroids change location instead of player). New asteroids spawn as old ones fall off the screen creating an infinite asteroid field feeling. Running on my Nexus 5, I noticed that after about 3 seconds, the asteroids moving down the screen became choppy, despite my game loop set to run at 60fps.

I'm looking for the fastest way to take an image frame received from the MediaCodec decoder and draw it to the Android device screen. The important constraints and explanations are: Cannot use MediaPlayer. No intermediate app allowed. Must draw output frames from the MediaCodec decoder to the screen as quickly as possible (minimize latency). The available decoder output formats are as follows: ColorFormat[0] 0x00000013 COLOR_FormatYUV420Planar ColorFormat[1] 0x00000015 COLOR_FormatYUV420SemiPlanar ColorFormat[2] 0x7F000001 OMX_SEC_COLOR_FormatNV12TPhysicalAddress ColorFormat[3] 0x7FC00002 OMX
