Subject: input/camera_api: activate user-desired camera device
X-Git-Tag: accepted/tizen/unified/20240903.110722~69
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0cfa1df3a41acc64452c6f6006ed4e524a31c28a;p=platform%2Fcore%2Fapi%2Fsingleo.git

input/camera_api: activate user-desired camera device

Activate user-desired camera device by adding updateAvailableCameraDevices
and setActivateCameraDevice functions. With this patch, Camera API backend
collects valid camera device list and activates user-desired camera device
with config.device_id which is passed by user.
