间隔3秒钟，不停的开启和关闭摄像头，大概运行40分钟左右就会出现崩溃，大概是内存不足引起的，但这是uvccamera自身的错误，请问有没有遇到过这种情况的朋友 调用代码：
打开摄像头的接口 public boolean startCam() { mUSBMonitor =new USBMonitor(mContext,mOnDeviceConnectListener); mUSBMonitor.register(); filter = DeviceFilter.getDeviceFilters(mContext, device_filter_id); if (filter.size() > 0){ item = mUSBMonitor.getDeviceList(filter.get(0)); if (item.size() > 0){ for(int i=0; i< item.size(); i++) { for (int c=0; c<8; c++) { if (item.get(i).getVendorId() == arrayCamPro[c].vid && item.get(i).getProductId() == arrayCamPro[c].pid) { mUSBMonitor.requestPermission(item.get(i)); if (!mUSBMonitor.hasPermission(item.get(i))){ OpenUSBCamThread.start(); break; } } } } }else { //callback.openFail(); return false; } }else { //callback.openFail(); return false; } return true; }
关闭摄像头的代码： public void closeCam() { if (mUVCCamera != null) { mUVCCamera.stopPreview(); mUVCCamera.destroy(); mUVCCamera = null; } if (mUSBMonitor != null) { mUSBMonitor.unregister(); mUSBMonitor.destroy(); mUSBMonitor = null; } }
