Dropped Frames - which frames are dropped?

Post by Gajowy » Sat Oct 07, 2017 6:38 pm

Hi,
Which frames are dropped when system is not able to collect them?
When next getImageData is processed which one frame is saved ?

For example:
frame #0 --> getImageData --> frame #0 saved
frame #1 --> dropped
frame #2 --> dropped
frame #3 --> dropped
frame #4 --> getImageData --> which frame is save? #1 or #4 ?

Kind regards,
Gajowy

you'd better run under snap mode to do more precise control like this

I follow this advice, thank you!
Nevertheless it would be useful to know how it works. Could you ask a software developer at some point, please?

when system is busy, always the newest frame is droped
the newest frame can store in buffer until you get out the old one
otherwise it's always old

You mean "internal camera buffer" or the one created by me in my application?
