HDR mode is disabled
maybe was just written by autoexposure
program next two frames after target_frame
skip 2 frames from 'frame' (use absolute to add tolerance against being too late)

in HDR mode - wait until we get a histogram from a normal frame (only needed to re-sync after long delays uses global variables for files and mmap-ed data so they are accessible everywhere
wait for Y only
nothing needed, just waiting for some frames to be skipped
just wait until the Y histogram will available for non-HDR frame
