Mp4Composer-android

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

Gradle

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();

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.
