ios5 - Filter Live camera feed -


so i've been using uiimagepickercontroller access camera photo , video capture, wanted apply filters on 2 sources, succeeded filtering token photos i'am having trouble finding solution rest, need access raw image data : live image feed camera showing , apply filter , show filtered ones instead. or advice appreciated.

uiimagepickercontroller doesn't give low level access camera buffer.

you should setup avcapturesession , use delegate process cmsamplebufferref

take @ avcam & squarecam demos apple, give introduction video capture.
