initHalPreviewWindow(&mHalPreviewWindow); initHalPreviewWindow(&mHalTapin); initHalPreviewWindow(&mHalTapout); #else initHalPreviewWindow(); #endif return rc; } 此处通过module->method->open()方法真正打开Camera设备, 其中module的定义在以下路径:frameworks/base/services/camera/libcameraservice/Camera...
实例化Camera Hal接口 hardware,hardware调用initialize()进入HAL层打开Camear驱动。 CameraHardwareInterface中initialize()定义在以下路径:frameworks/base/services/camera/libcameraservice/CameraHardwareInterface.h 代码如下: status_t initialize(hw_module_t *module) { LOGI("Opening camera %s", mName.string());...
MEMORY_OVERLAY；这个属性在hardware/rockchip/camera/CameraHal/CameraSocAdapter.cpp中指定；...
上面这样改的原理是,我们在打开一个camera的时候,会调用到CameraService.cpp里的connectHelper函数,在这个函数里,会调用handleEvictionsLocked这个函数去检测当前有无冲突。再跟进handleEvictionsLocked这个函数,会发现它又调用了mActiveClientManager.wouldEvict这个函数,当这个函数返回有冲突的client后,紧接着,就会调用下面的...
2.4 流的创建流程-从hal到kernel 细致的调用流程,参考【Camera专题】HAL层-addChannel和startChannel简析 这里写一下关键的接口 用户空间:HAL层 hardware/qcom/camera/QCamera2/HAL/QCamera2HWI.cpp int32_t QCamera2HardwareInterface::addPreviewChannel(){`CDBG_HIGH("%s :zcf camera_handle=%d ops=%p",__...
Android Camera HAL设计初步 使用zc301 USB摄像头,这个摄像头返回JPEG图形留,camera的preview需要进行jpeg解码(没做),但是可以直接take jpeg照片。 1、修改你的BoardConfig.mk...FakeCamera.cpp->UsbCamera.cpp 目前只实现了基本功能 该文件可以按照V4L2流程来写 网上也有现成的...
