VidEffects

This is an Android library which can be used to apply different Filters/Effects on videos. It uses vertexShaders and fragmentShaders to apply effects on GLSurfaceView. It uses MediaPlayer instance for playing videos on GlSurfaceView. See the sample app in order to see a working demo.

Change Log

1.1.0 - Added ability to save video once you apply a FILTER (not EFFECT), Updated Sample app with a detailed example, 

Supported Effects

The following list of effects are currently avaialble and can be applied using VidEffects

Limitations

  • The effects applied using this library are temporary. What that means is that the original video doesn't change. Effects are only applied during video playback and once the video ends the effects end with it.
  • Minimum Supported Android version is 21 (Lollipop)
  • Saving video available only for Filters and requires Android 23 min api version.For more information check the file VideoController.
  • Other ways to save video once effect/filter is applied FFmpeg to apply effects on videos. Details about how to do that can be seen on this wiki page
  • Some emulators have problems during video playback so try on real device when that happens e.g: Android Lollipop emulators don't show video.

How to use it

  • Add the following code to your project's build.gradle file
  repositories {
        jcenter()
    }
  • Add the following gradle path to your app/build.gradle file
dependencies {
// Gradle path for VidEffects
    implementation "com.sherazkhilji.videffects:videffects:1.1.0"
}
  • Then you need to add VideoSurfaceView either using java code or as xml in your layout file.
<com.sherazkhilji.videffect.view.VideoSurfaceView
       android:id="@+id/mVideoSurfaceView"
       android:layout_width="match_parent"
       android:layout_height="match_parent" />
  • Then you need to reference the VideoSurfaceView and call its init() method in your Activity or Fragment onCreate() supplying it with a MediaPlayer instance and a Video Effect. Also you would need to call VideoSurfaceView onResume() in your Activity or Fragment onResume() so that your video is rendered properly.
 @Override
   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mResources = getResources();
    mMediaPlayer = new MediaPlayer();

    try {
     // Load video file from SD Card
     // File dir = Environment
     // .getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
     // File file = new File(dir,
     // "sample.mp4");
     // mMediaPlayer.setDataSource(file.getAbsolutePath());
     // -----------------------------------------------------------------------
     // Load video file from Assets directory
     AssetFileDescriptor afd = getAssets().openFd("sample.mp4");
     mMediaPlayer.setDataSource(afd.getFileDescriptor(),
       afd.getStartOffset(), afd.getLength());
    } catch (Exception e) {
     Log.e(TAG, e.getMessage(), e);
    }
    // Initialize VideoSurfaceView using code
    // mVideoView = new VideoSurfaceView(this);
    // setContentView(mVideoView);
    // or
   
    mVideoView = (VideoSurfaceView) findViewById(R.id.mVideoSurfaceView);
    mVideoView.init(mMediaPlayer,
      new DuotoneEffect(Color.YELLOW, Color.RED));
           setContentView(R.layout.activity_sampleplayer);
   }

   @Override
   protected void onResume() {
    super.onResume();
    mVideoView.onResume();
   }
  • Incase of any confusion, check the file SamplePlayerActivity for a complete example on how to apply different Effects on your videos.
  • For Advance implementation and saving Filters, check the file VideoActivity
