This library apply video filter on generate an Mp4 and on ExoPlayer video and Video Recording with Camera2.
Android MediaCodec API is used this library.
- apply video filter, scale, and rotate Mp4.
- apply video filter on ExoPlayer video.
- apply video filter on Video Recording with Camera2.
 Sample Video No filter |
 GlGlayScaleFilter apply |
 GlMonochromeFilter apply |
 GlWatermarkFilter apply |
Step 1. Add the JitPack repository to your build file
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}Step 2. Add the dependency
dependencies {
implementation 'com.github.MasayukiSuda:GPUVideo-android:v0.1.2'
// if apply video filter on ExoPlayer video
implementation 'com.google.android.exoplayer:exoplayer-core:2.15.1'
} new GPUMp4Composer(srcMp4Path, destMp4Path)
.rotation(Rotation.ROTATION_90)
.size((width) 540, (height) 960)
.fillMode(FillMode.PRESERVE_ASPECT_FIT)
.filter(new GlFilterGroup(new GlMonochromeFilter(), new GlVignetteFilter()))
.listener(new GPUMp4Composer.Listener() {
@Override
public void onProgress(double progress) {
Log.d(TAG, "onProgress = " progress);
}
@Override
public void onCompleted() {
Log.d(TAG, "onCompleted()");
runOnUiThread(() -> {
Toast.makeText(context, "codec complete path =" destPath, Toast.LENGTH_SHORT).show();
});
}
@Override
public void onCanceled() {
Log.d(TAG, "onCanceled");
}
@Override
public void onFailed(Exception exception) {
Log.e(TAG, "onFailed()", exception);
}
})
.start();
| method | description |
|---|---|
| rotation | Rotation of the movie, default Rotation.NORMAL |
| size | Resolution of the movie, default same resolution of src movie |
| fillMode | Options for scaling the bounds of an movie. PRESERVE_ASPECT_FIT is fit center. PRESERVE_ASPECT_CROP is center crop , default PRESERVE_ASPECT_FIT |
| filter | This filter is OpenGL Shaders to apply effects on video. Custom filters can be created by inheriting GlFilter.java. , default GlFilter(No filter). Filters is here. |
| videoBitrate | Set Video Bitrate, default video bitrate is 0.25 * 30 * outputWidth * outputHeight |
| mute | Mute audio track on exported video. Default mute = false. |
| flipVertical | Flip Vertical on exported video. Default flipVertical = false. |
| flipHorizontal | Flip Horizontal on exported video. Default flipHorizontal = false. |
Create SimpleExoPlayer instance.
In this case, play MP4 file.
Read this if you want to play other video formats.
TrackSelector trackSelector = new DefaultTrackSelector();
// Measures bandwidth during playback. Can be null if not required.
DefaultBandwidthMeter defaultBandwidthMeter = new DefaultBandwidthMeter();
// Produces DataSource instances through which media data is loaded.
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(context, Util.getUserAgent(context, "yourApplicationName"), defaultBandwidthMeter);
// This is the MediaSource representing the media to be played.
MediaSource mediaSource = new ExtractorMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(MP4_URL));
// SimpleExoPlayer
player = ExoPlayerFactory.newSimpleInstance(context, mediaSource);
// Prepare the player with the source.
player.prepare(videoSource);
player.setPlayWhenReady(true);Create GPUPlayerView and set SimpleExoPlayer to GPUPlayerView.
gpuPlayerView = new GPUPlayerView(this);
// set SimpleExoPlayer
gpuPlayerView.setSimpleExoPlayer(player);
gpuPlayerView.setLayoutParams(new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
// add gpuPlayerView to WrapperView
((MovieWrapperView) findViewById(R.id.layout_movie_wrapper)).addView(gpuPlayerView);
gpuPlayerView.onResume();Set Filter. Filters is here.
Custom filters can be created by inheriting GlFilter.java.
gpuPlayerView.setGlFilter(new GlSepiaFilter());SetUp on onResume method.
sampleGLView = new GLSurfaceView(getApplicationContext());
FrameLayout frameLayout = findViewById(R.id.wrap_view);
frameLayout.addView(sampleGLView);
gpuCameraRecorder = new GPUCameraRecorderBuilder(activity, sampleGLView)
.lensFacing(LensFacing.BACK)
.build();Release on onPause method.
sampleGLView.onPause();
gpuCameraRecorder.stop();
gpuCameraRecorder.release();
gpuCameraRecorder = null;
((FrameLayout) findViewById(R.id.wrap_view)).removeView(sampleGLView);
sampleGLView = null;Start and Stop Video record.
// record start.
gpuCameraRecorder.start(filepath);
// record stop.
gpuCameraRecorder.stop();This filter is OpenGL Shaders to apply effects on camera preview. Custom filters can be created by inheriting GlFilter.java. , default GlFilter(No filter). Filters is here.
gpuCameraRecorder.setFilter(GlFilter);Other methods.
// if flash enable, turn on or off camera flash.
gpuCameraRecorder.switchFlashMode();
// autofocus change.
gpuCameraRecorder.changeAutoFocus();
// set focus point at manual.
gpuCameraRecorder.changeManualFocusPoint(float eventX, float eventY, int viewWidth, int viewHeight);
// scale camera preview
gpuCameraRecorder.setGestureScale(float scale);| method | description |
