Is there a way I can grab frames from android camera using openCV4android or JAVA Api without any JNI calls?
The reason is : I want a fixed fps for a particular application. I dont want to use the call back methods onCameraFrame (from CvCameraViewListener) or onPreviewFrame( using camera.onPreviewcallBack), which fails to give a fixed FPS.
I am desperate for help, after spending days :(
You're probably going to have a hard time doing this unless you want a frame rate that is quite low (like 5 fps, depending on your hardware). Go ahead and implement the callback interface but keep track of the timing and throw away any frames that you don't want.
Low FPS is not a problem for me, but it must be fixed.
I cant used callback interface for it because they are not being called after an exact period od time. Its varying by a huge factor, which makes my intentions infeasible. with c++ I can use VideoCapture::grab() and retrieve() to grab image at a particular instant of time. that solves my issue. But can I do the same in JAVA somehow w/o JNI call?
