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. Checkthis for behavior. Sample source code isthis.
filter	This filter is OpenGL Shaders to apply effects on video. Custom filters can be created by inheritingGlFilter.java. , default GlFilter(No filter). Filters ishere.
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. Checkthis.
timeScale	Set TimeScale. default value is 1f. should be in range 0.125 (-8X) to 8.0 (8X)
