技术背景
在写如何实现Android平台GB28181设备对接Camera2数据说明之前，我在前两年的blog就有针对camera2的RTMP直播推送模块做过技术分享：
在Google 推出Android 5.0的时候, Android Camera API 版本升级到了API2(android.hardware.camera2), 之前使用的API1(android.hardware.camera)就被标为 Deprecated 了。
Camera API2相较于API1有很大不同, 并且API2是为了配合HAL3进行使用的, API2有很多API1不支持的特性, 比如:
- 更先进的API架构；
- 可以获取更多的帧(预览/拍照)信息以及手动控制每一帧的参数；
- 对Camera的控制更加完全(比如支持调整focus distance, 剪裁预览/拍照图片)；
- 支持更多图片格式(yuv/raw)以及高速连拍等。
Camera2 API调用基础流程
- 通过context.getSystemService(Context.CAMERA_SERVICE) 获取CameraManager；
- 调用CameraManager .open()方法在回调中得到CameraDevice；
- 通过CameraDevice.createCaptureSession() 在回调中获取CameraCaptureSession；
- 构建CaptureRequest, 有三种模式可选 预览/拍照/录像.；
- 通过 CameraCaptureSession发送CaptureRequest, capture表示只发一次请求, setRepeatingRequest表示不断发送请求；
- 拍照数据可以在ImageReader.OnImageAvailableListener回调中获取, CaptureCallback中则可获取拍照实际的参数和Camera当前状态。
本次更新，系在Android平台camera2 RTMP推送的基础上，继续支持Android平台GB28181设备和语音广播接入，此外，添加了基于层结构设计的动态水印（动态水印的场景应用特别实在传统行业，重要性不言而喻。包含实时文字水印、图片水印），camera2的技术优越性不再赘述，无图无真相：
新的demo增加了动态水印设置、轻量级RTSP服务、实时录像、快照等。
技术实现
先说camera2的数据采集：
代码语言：javascript复制private class OnImageAvailableListenerImpl implements ImageReader.OnImageAvailableListener {
@Override
public void onImageAvailable(ImageReader reader) {
Image image = reader.acquireLatestImage();
if ( image != null )
{
if ( camera2Listener != null )
{
camera2Listener.onCameraImageData(image);
}
image.close();
}
}
}获取到的数据，投递到SmartPublisher Jni层：
代码语言：javascript复制@Override
public void onCameraImageData(Image image) {
Rect crop_rect = image.getCropRect();
if (isPushingRtmp || isRTSPPublisherRunning || isGB28181StreamRunning || isRecording) {
if (libPublisher != null) {
Image.Plane[] planes = image.getPlanes();
int w = image.getWidth(), h = image.getHeight();
int y_offset = 0, u_offset = 0, v_offset = 0;
if (!crop_rect.isEmpty()) {
w = crop_rect.width();
h = crop_rect.height();
y_offset = crop_rect.top * planes[0].getRowStride() crop_rect.left * planes[0].getPixelStride();
u_offset = (crop_rect.top / 2) * planes[1].getRowStride() (crop_rect.left / 2) * planes[1].getPixelStride();
v_offset = (crop_rect.top / 2) * planes[2].getRowStride() (crop_rect.left / 2) * planes[2].getPixelStride();
;
// Log.i(TAG, "crop w:" w " h:" h " y_offset:" y_offset " u_offset:" u_offset " v_offset:" v_offset);
}
int scale_w = 0, scale_h = 0, scale_filter_mode = 0;
scale_filter_mode = 3;
libPublisher.PostLayerImageYUV420888ByteBuffer(publisherHandle, 0, 0, 0,
planes[0].getBuffer(), y_offset, planes[0].getRowStride(),
planes[1].getBuffer(), u_offset, planes[1].getRowStride(),
planes[2].getBuffer(), v_offset, planes[2].getRowStride(), planes[1].getPixelStride(),
w, h, 0, 0,
scale_w, scale_h, scale_filter_mode, cameraImageRotationDegree_);
}
}
}PostLayerImageYUV420888ByteBuffer()接口设计如下：

* @param scale_height: 缩放高, 必须是偶数, 0或负数不缩放
*
* @param scale_filter_mode: 缩放质量, 传0使用默认速度,可选等级范围是:[1,3],值越大缩放质量越好, 但速度越慢
*
* @param rotation_degree: 顺时针旋转, 必须是0, 90, 180, 270, 注意:旋转是在缩放, 垂直/水品反转之后再做, 请留意顺序

}我们demo实现的横竖屏切换时，自动切换分辨率，有些国标平台，对分辨率切换支持的并不友好，这点可以根据实际情况调整，比如固定横竖屏。
总的来说，camera2对焦等各个方面，确实优于camera，替换升级也是大势所趋。
