Store Camera Preview After Every 1 Second Android

Question

I want to store the Camera Preview after every second. Problem is the frame rate cannot go below 20-24.

Currently it stores around 170 images in 5 sec. onPreviewFrame is being called ULTRA frequently which i want to slow down to 1 preview per second. I used Thread.sleep() but i guess its not a nice of doing it. I want to store 1 image in 1 sec. Any leads on this?

Thanks

Can you just ignore 19 of the 20 frames per second in your callback? — fadden, Feb 17 '15 at 16:34
yea i did that by calling the store function after a multiple of 20. its solved — gursahib.singh.sahni, Feb 18 '15 at 06:31
@gursahib.singh.sahni How you did this. I also want to capture preview frame after 500ms, that means i want to take only 1 preview frame per 500 milliseconds. — sam_k, Jun 01 '15 at 01:04
@sam_k , i guess FPS is device dependent. You may skip capturing the preview by calling the capture method after the desired interval. — gursahib.singh.sahni, Jun 01 '15 at 05:37

Instead of setPreviewCallback go for setOneShotPreviewCallback: This callback gives you only one frame and the callback will get cleared. You can keep calling this at every one second interval or when you are done with storing previous frame.
