Photography API

[Igor Mironchick]

Hi.

Is anybody worked with gstreamer photography API?

Which type of GstElement can be bind to the GstPhotography?

I mean that I create pipeline like this:

camerasrc-> csp filter -> image filet -> image sink

How can I initialize GstPhotography object to use, for example, gst_photography_set_flash_mode function?

I have no idea. Is there somewhere example? Can anybody point me up... Thx.

GstPhotography is an interface. You need a camera source that implements
it. Such an implementation is hardware specific right now, as the v4l2
kernel interface does not yet have such feature standartized :/
There are not many of those yet, the v4l2camsrc on Nokia N900 devices
does it.

You and get the photography implementation in camerabin(gst-plugins-bad/gst/camerabin/).

Please refer to the example code in  

gst-plugins-bad/tests/examples/camerabin/gst-camera-perf.c

and

gst-plugins-bad/tests/examples/camerabin/gst-camera.c

on how to use the gst_photography_set_flash_mode function.

 

I know v4l2camsrc is a modified v4l2src. It implements the photography interface and available in N900 platform.

Thanks.
