Android Question How to record the time interval of change of pixel color in video

[mkvidyashankar]

Hi
I am developing an application in which I have to record the time interval of change of pixel color while capturing video. the color variation is fixed but frequency is different. I found that I can use camEx library, but not sure how to implement this. Any help please.

See how the bitmap is fetched from the preview frames in this example: Android based Closed Circuit TV (CCTV) example

However checking each bitmap every time will be too slow.

Thanks Erel

In the above method image is converted into byte
How can I retrieve pixel data from byte
actually I want one or two pixel color information in a particular quadrant.

You can use Bitmap.GetPixel to get the color of a pixel.

PreviewImageToJpeg returns a Jpeg image. It will be difficult to extract the pixel value directly from this array.
