This library generate an Mp4 movie using Android MediaCodec API and apply filter, scale, trim, transcode, crop, mute and rotate Mp4.
Idea from: android-transcoder

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:v0.4.0'
}
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();
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. |
