i run sample in opencv2.4.8 sdk on allwinner a10 pad which has one 1.0G Hz arm A8 core. i find the sequence of frame retrieved from camera is in chaos.the previous frame is interlaced with later frame.and if i run the same sample on faster chip such as mt6589 platform which has four 1.2Ghz A7 core,i could get correct sequence of frame.i test capture camera in native c++ mode and java mode,i could get same result.the difference between two mode is native capture fps is better than jave camera capture.and the incorrect sequence of frame is less in native mode.

who could tell me why the sequence of frame from camera is not correct in poor performance arm platform?in this case,if my algorithm is some complex,the project will fall into chaos.

thanks anyway.
