        implementation 'com.github.MasayukiSuda:Mp4Composer-android:v0.4.1'
}

Usage

    new Mp4Composer(srcMp4Path, destMp4Path)
            .rotation(Rotation.ROTATION_90)
            .size((width) 540, (height) 960)
            .fillMode(FillMode.PRESERVE_ASPECT_FIT)
            .filter(new GlFilterGroup(new GlMonochromeFilter(), new GlVignetteFilter()))
            .trim((trimStartMs) 200, (trimEndMs) 5000)
            .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

                }

                @Override
                public void onFailed(Exception exception) {
                    Log.e(TAG, "onFailed()", exception);
