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: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
                public void onCanceled() {
                    Log.d(TAG, "onCanceled");
                }

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

Builder Method

method	description
rotation	Rotation of the movie, default Rotation.NORMAL
size	Resolution of the movie, default same resolution of src movie. If you specify a resolution that MediaCodec does not support, an error will occur.
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. FILLMODE_CUSTOM is used to crop a video. Check this for behavior. Sample source code is this.
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`.
trim	Trim both audio and video tracks to the provided start and end times, inclusive. Default does not trim anything from the start or end.
flipVertical	Flip Vertical on exported video. Default `flipVertical = false`.
flipHorizontal	Flip Horizontal on exported video. Default `flipHorizontal = false`.
videoFormatMimeType	The mime type of the video format on exported video. default AUTO. Suppurt HEVC, AVC, MPEG4, H263. Check this.
