1 前言

功能简介：

• 视频录制、播放
• 自定义视频大小
• 翻转摄像头、翻转后图像翻转功能
• 触摸对焦、两指放大缩小

版本更新记录

参考开源项目：

javacv - 使用opencv+ffmpeg，功能最完整的项目，可以用于拓展参考

RecordVideoDemo - 参照javacv中的Demo使用camera+ffmpeg实现，本项目基于该开源项目开发

VideoRecorder - 也是一个不错的录制视频项目，不过so库已经太旧了，sdk超过22无法通过

2 接入SDK

在gradle中添加

...
dependencies {
    ...
    compile 'com.tsy.video:video-sdk:1.0.0'
}
...

3 使用SDK

具体代码见app中的RecorderActivity

3.1 初始化

//初始化摄像头
mCamera = CameraHelper.getCamera(this, mCameraFace);       //默认打开后置摄像头

//初始化摄像预览界面
mCameraPreviewView = (CameraPreviewView) findViewById(R.id.camera_preview);
mCameraPreviewView.init(mCamera, RECORDER_WIDTH, RECORDER_HEIGHT);

//初始化recorder
mRecorder = new Recorder.Builder()
        .context(getApplicationContext())
        .camera(mCamera)
        .cameraFace(mCameraFace)
        .outputSize(RECORDER_WIDTH, RECORDER_HEIGHT)
        .outputFilePath(path)
        .build();

3.2 开始录像

mRecorder.start();

3.3 暂停录像

mRecorder.stop();

3.4 切换摄像头

if(mCameraFace == Camera.CameraInfo.CAMERA_FACING_BACK) {
    mCameraFace = Camera.CameraInfo.CAMERA_FACING_FRONT;
} else {
    mCameraFace = Camera.CameraInfo.CAMERA_FACING_BACK;
}

mCamera = CameraHelper.getCamera(this, mCameraFace);
mCameraPreviewView.switchCamera(mCamera);
mRecorder.switchCamera(mCamera, mCameraFace);

3.5 获取当前录制状态

mRecorder.isRecording()

3.6 获取当前录制时间

mRecorder.getRecordingTime()
