This library generate an Mp4 movie using Android MediaCodec API and apply filter, scale, trim, transcode, crop, timeScale, mute and rotate Mp4.
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
Sample Video No filter |
GlGlayScaleFilter apply |
GlMonochromeFilter apply |
GlWatermarkFilter apply |
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'
}
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. |
timeScale | Set TimeScale. default value is 1f. should be in range 0.125 (-8X) to 8.0 (8X) |
