| 2013-07-16 19:20:07 -0600 | asked a question | Native Camera stop retrieving frames from Samsung S4 Camera When running sample Tutorial-1- Camera preview and switch to native camera preview. It works for some time then stop retrieving frames. This happens randomly. We tried getting frames in C Native level using VideoCapture.grap()/retrieve() as well as Java level same code and we still getting the same behavior. Here is the error we always get : 07-17 02:16:04.136: E/OpenCV_NativeCamera(30730): CameraHandler::Notify: msgType=1 ext1=200 ext2=0 07-17 02:16:04.591: W/BufferQueue(30730): freeAllBuffersLocked called but mQueue is not empty So what does this error mean and how can we fix it? |
