Android视频录制，自定义视频大小，支持触摸对焦、两指放大缩小、切换摄像头. 采用FFmpeg对进行视频帧剪裁旋转切割，包体积4M
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
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
在gradle中添加
...
dependencies {
...
compile 'com.tsy.video:video-sdk:1.0.0'
}
...
具体代码见app中的RecorderActivity
//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();
mRecorder.start();
mRecorder.stop();
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);
mRecorder.isRecording()
mRecorder.getRecordingTime()
