Video Memory

I am analyzing my app - an interactive book for iPads - which has a lot of native.new.videos. With memory monitoring in Corona, I see one page-change memory spike with 120 mb ( using director). All other pages use between 20-70 mb. With a 160 mb limit on Ipad2, it seems o.k.

But: when I check my app in Xcode simulator Instruments, I notice an “All Allocation Live Bytes” usage of 200 mb, when a native.new.video is playing. The videofile in m4v has only 14 mb.

One one specific page, I have 4 short native videos waiting to be started by 4 buttons. Here “All Allocation Live Bytes” usage is 541mb. On my Ipads 2+3 everything runs fine, even when 10 other apps are resumed in memory.

So my big questions are : What are the limits for “All Allocation Live Bytes” on iPad?

Are native videos streaming?

Where do I see actual texture and video memory usage in Xcode Instruments?

Could I get into troubles with ipad mini?

Please help.
