* move setvideomode to common place * implement more croping and 3d support * more api unification * more refactoring * osx fix * next step * add a mock for osx grabber. Now it is possible to test compile on none osx platforms. * more unifications ... * remove obsolete includes and grabbers are not dyn allocated. dispmanx needs rework an probaly not work atm * first version of dispmanx mock. it compiles, but outputs a black image * now dispmanx mock works! * activate mocks in travis linux build prepare dispmanx to rgb image out * dispmanx now with image rgb output fix deadlock with w/h -1 in grabber v4l cleanups * fix json * fix some runtime stuff * Update FramebufferWrapper.cpp fix missing code * unify grabframe * 3d and croping for amlogic * fix setimage not working * make use of templates save some codelines * save more code lines
