SimpleVideoEditor

Video editor library for android, implemented with android media framework and opengl es 2.0.

The aim of this library is:

1. tiny size(no ffmpeg, 103KB for now)
2. simple api
3. powerful feature

NOTE

This library is still under development, apis will be changed.

Any suggestion is welcome, you can raise issues or pull requests, thx.

How to use

Init

// init with context, you can do this in application or activity.
VideoEditorManager.getManager().init(context);

Define progress listeners:

// EditStageListener use to listener every stage progresss.
private EditStageListener mStageListener = new EditStageListener() {
    @Override
    public void onStart(String action) {
        super.onStart(action);
        Log.d(TAG, "EditStageListener, onStart: " + action);
        mActionView.setText(action + ": started");
    }

    @Override
    public void onProgress(String action, float progress) {
        super.onProgress(action, progress);
        Log.d(TAG, "EditStageListener, onProgress: " + action + ", progress: " + progress);
        mActionView.setText(action + ": progress");
        mProgressView.setText(String.format("%.2f%%", progress * 100));
    }

    @Override
    public void onSucceeded(String action) {
        super.onSucceeded(action);
        Log.d(TAG, "EditStageListener, onSucceeded: " + action);
        mActionView.setText(action + ": succeed");
        if (Constants.ACTION_MERGE_VIDEOS.equals(action)) {
            mToken = -1;
        }
    }

    @Override
    public void onFailed(String action) {
        super.onFailed(action);
        Log.d(TAG, "EditStageListener, onFailed: " + action);
        mActionView.setText(action + ": failed");
    }
};
// EditListener use to listen overall progress.
private EditListener mEditListener = new EditListener() {
    @Override
    public void onStart(long token) {
        super.onStart(token);
        Log.d(TAG, "EditListener, onStart token: " + token);
    }

    @Override
    public void onProgress(long token, float progress) {
        super.onProgress(token, progress);
        Log.d(TAG, "EditListener, onProgress: " + progress + ", token: " + token);
    }

    @Override
    public void onSucceeded(long token, File outputFile) {
        super.onSucceeded(token, outputFile);
        Log.d(TAG, "EditListener, onSucceeded token: " + token + ", output: " + outputFile);
        mToken = -1;
    }

    @Override
    public void onFailed(long token) {
        super.onFailed(token);
        Log.d(TAG, "EditListener, onFailed token: " + token);
        mToken = -1;
    }
};

Define actions

// video water mark config
WaterMarkFilter waterMarkFilter = new WaterMarkFilter.Builder()
        .watermark(BitmapFactory.decodeResource(getResources(), R.drawable.watermark))
        .position(100, 200)
        .scaleFactor(1f)
        .startFrom(5 * 1000)
        .duration(5 * 1000)
        .build();
// video filter config.
VideoFrameLookupFilter lookupFilter = new VideoFrameLookupFilter.Builder()
        .curve(BitmapFactory.decodeResource(getResources(), R.drawable.filter9))
        .strength(1f)
        .startFrom(5 * 1000)
        .duration(5 * 1000)
        .build();
// filter action with water mark and filter config.
VideoFilterAddAction filterAddAction = new VideoFilterAddAction.Builder()
        .watermarkFilter(waterMarkFilter)
        .frameFilter(lookupFilter)
        .build();

// bgm add action
VideoBgmAddAction bgmAddAction = new VideoBgmAddAction.Builder()
        .bgmFile(new File(Environment.getExternalStorageDirectory(), "videoeditor/music.mp3"))
        .videoFrom(5 * 1000)
        .videoDuration(7 * 1000)
        .override(true)
        .bgmFrom(5 * 1000)
        .build();

// bgm remove action
VideoBgmRemoveAction bgmRemoveAction = new VideoBgmRemoveAction.Builder()
        .from(3 * 1000)
        .duration(8 * 1000)
        .build();

// cut action
VideoCutAction cutAction = new VideoCutAction.Builder()
        .from(5 * 1000)
        .duration(10 * 1000)
        .build();

// merge action
VideoMergeAction mergeAction = new VideoMergeAction.Builder()
        .merge(new File(Environment.getExternalStorageDirectory(), "videoeditor/input.mp4"))
        // put input file here.
        .inputHere()
        .merge(new File(Environment.getExternalStorageDirectory(), "videoeditor/input2.mp4"))
        .merge(new File(Environment.getExternalStorageDirectory(), "videoeditor/input3.mp4"))
        .merge(new File(Environment.getExternalStorageDirectory(), "videoeditor/input4.mp4"))
        .build();

// start it! token is the unique id of this task.
mToken = VideoEditorManager.getManager()
        // give the input file.
        .edit(new File(Environment.getExternalStorageDirectory(), "videoeditor/input.mp4"))
        // all actions here will be executed in define order.
        .withAction(cutAction)
        .withAction(bgmAddAction)
        .withAction(filterAddAction)
        .withAction(bgmRemoveAction)
        .withAction(mergeAction)
        // give the output file.
        .saveAs(new File(Environment.getExternalStorageDirectory(), "videoeditor/output.mp4"))
        // commit action list, and actions will be executed right now.
        .commit(mEditListener, mStageListener);

Cancel task

// cancel task with token.
VideoEditorManager.cancel(mToken);
