This library generate an Mp4 movie using Android MediaCodec API and apply filter, scale, and rotate Mp4.
Idea from: android-transcoder
 Sample Video No filter |
 GlGlayScaleFilter apply |
 GlMonochromeFilter apply |
 GlWatermarkFilter apply |
dependencies {
// jCenter
implementation 'com.daasuu:Mp4Composer-android:0.1.0'
} new Mp4Composer(srcMp4Path, destMp4Path)
.rotation(Rotation.ROTATION_90)
.size((width) 540, (height) 960)
.fillMode(FillMode.PRESERVE_ASPECT_FIT)
.filter(new GlSepiaFilter())
.listener(new Mp4Composer.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();
