I want to use My DSLR(canon 7d) as a web cam for one of my project what i did is that i installed libphoto2(Becose canon 7d supports ptp protocol)in my Pi(Ubuntu mate installed) all the commands associated with libphoto2 is working fine other ways able to capture images using this software. What i want to do is that i want to see a live preview from the camera over my browser so that i can capture images from my system. Other ways around how to use monitor connected to pi as the monitor for DSLR.
Why i want to do this
I am working with a php software called http://www.blaize.net/2014/04/gphoto-webui-a-php-web-ui-for-gphoto2/ When i load this software there will be a capture button if i press on that capture button the software will capture an image and load on memory card I want to get a live preview along with this,So that i can arrange camera by looking at the monitor how can i achieve this? More generally i want a live preview from the camera over my monitor through browser.
