Okay, you told us what you want but where is the problem? What have you
done so far, did you use Google to find an answer on your own?

That is not technologically achivable.

2 MB / seconds in day = 2 megabytes / 86 400 = 24.2725926 bytes / s

With 15 frames/second or 29.97 frames/second you get approximately one
byte per frame. One byte is not enough to capture a frame.

There are no feasible alternatives for constraints.

So the best you can do is what security cameras do, capture frames
with seconds between or do motion detect and only record during
motions.

Er, couldn't the OP mean that they want a bunch of 2MB files per day?

Possible. No reason for wanting footage chunked this way occurs to me
-- perhaps a failure of imagination on my part. Further I may be
biased by experience writing surveillance software where files did not
need be chunked.

Another way of interpreting your request is you are happy to have
gigabytes of stuff recorded each day so long as the chunks are no
bigger than 2 MB, and you get lossless flips between chunks.
Is that what you wanted?
