I have never understood why this happens, but *oh well*. What actual fps does ffmpeg report while processing? Does the camera deliver the 30 fps, and can ffmpeg handle them (speed=1.0x)?

If the frame's timestamps are borked, and/or frames are duplicated or missing, probably not. Try your options above first.
