【模块名_概率】简要描述：
使用C++直接调用camera_framework接口实现拍照功能，但阻塞在等待OnBufferAvailable。本地摄像头不会存在该问题。
【环境信息】:
- 网络环境：同一WIFI下，网络稳定
- 硬件开发板型号：DAYU200 * 2
- 软件版本信息或tag节点：OH 4.0.10.15
- 测试环境
- 其他
【预置条件】:
- 在OH中添加自己的模块，最终一同编译成二进制可执行文件烧入开发板
- 拍照代码：
// 1. get manager instance and camera list
OHOS::sptr<CameraManager> camManagerObj = CameraManager::GetInstance();

Buffer的监听模块：
class CaptureSurfaceListener : public OHOS::IBufferConsumerListener {
public:
OHOS::CameraStandard::SurfaceType mode;
OHOS::sptr<OHOS::Surface> surface;
void OnBufferAvailable() override {
std::unique_lock<std::mutex> lk(captureLock);
int32_t flushFence = 0;
int64_t timestamp = 0;
OHOS::Rect damage; // initialize the damage
OHOS::sptr<OHOS::SurfaceBuffer> buffer = nullptr;
surface->AcquireBuffer(buffer, flushFence, timestamp, damage);
if (buffer != nullptr) {
void *addr = buffer->GetVirAddr();
int32_t size = buffer->GetSize();
// Save the buffer(addr) to a file
int fd = open("/data/output.jpg", O_CREAT | O_RDWR);
if (fd <= 0) {
std::cout << "cannot open /data/output.jpg\n";
}
int res = write(fd, addr, size);
if (res < 0) {
std::cout << "write error\n";
}
close(fd);
std::cout << "image save\n";
surface->ReleaseBuffer(buffer, -1);
}
std::cout << "capture surface buffer end\n";
captureReady = true;
captureCond.notify_one();
}
};
【测试步骤】：
- hdc shell进入终端环境
- 调用实现好的程序：cameractl capture --camearId=1（其他实现细节没有在这里展示出来）
- 在/data/目录下可以看到保存的output.jpg
【预期结果】：
以下为本地摄像头拍摄的输出：
# cameractl capture --cameraId=0
camera obj list size = 2
id=lcam001,
position=2,
cameraType=1,
connectionType=0
id=4f334b3d83a1192d7370d2ce8d325291e33462bb4b3166805d069bc1e461df96__Camera_lcam001,
position=2,
cameraType=1,
connectionType=2
camera ready to open
camera open
create session
add input
format=2000, width=1280, height960
add output
ready to capture
image save
capture surface buffer end
capture finish
【实际结果】：
以下为远程摄像头拍摄的输出
# cameractl capture --cameraId=1
camera obj list size = 2
id=lcam001,
position=2,
cameraType=1,
connectionType=0
id=4f334b3d83a1192d7370d2ce8d325291e33462bb4b3166805d069bc1e461df96__Camera_lcam001,
position=2,
cameraType=1,
connectionType=2
camera ready to open
camera open
create session
add input
format=2000, width=1280, height960
add output
ready to capture

可以看到在拍摄过程中没有找到奇怪的Error，只是监听Buffer的操作没有被调用。不确定问题来源，由于camera_framework项目没有正确可编译的demo示例，可能这里的接口调用存在问题。同时也可能是分布式硬件的回调消息没有触发。
此外，分布式功能经过检验，使用分布式计算器等demo都能够正常运行。
