How to get current image without buffer image in libcamera?

[yang]

hi, Balaji

@Balaji

by setting camera buffer while init camera as 0
int ret = cam.initCamera(width, height, formats::RGB888, 0, 0);
I am still getting past image from camera ,while click pushbutton for first 5 times it gives past image at 6th time it gives current image.is there any buffer need to clear in camera or system hardware.if its need to clear buffer in hardware please give an instruction to clear it .

In the sample code, when bufferCount is set to 0, the if branch cannot be entered, resulting in the inability to set bufferCount, and the default bufferCount is finally used. You can remove “if (bufferCount)” and have a try.

by setting camera buffer while init camera as 1
int ret = cam.initCamera(width, height, formats::RGB888, 1, 0);
I am still getting past image from camera ,while click pushbutton for first 2 times it gives past image at
3rd time it gives current image.at default it stores 2 past image as buffer .

When bufferCount is set to 1. The previous two images are still in the past because they should be cached. Currently, clearing the buffer is not supported.
