camera_set_videovf_property()

(Deprecated) Configure one or more settings of the video viewfinder

Synopsis:

#include <camera/camera_api.h>
 
camera_error_t camera_set_videovf_property(handle,                 
                                           args...)

Since:

BlackBerry 10.0.0

Arguments:

handle

The handle returned by a call to the camera_open() function.

args...

A series of comma-delimited property-value pairs where each value must be a pointer a variable of the expected type.

Library:

libcamapi (For the qcc command, use the -l camapi option to link against this library)

Description:

Deprecated:

As of CAMERA_API_VERSION 3 (BlackBerry 10.3.0). Instead, use the camera_set_vf_property() function. For more information about new and deprecated viewfinder functionality, see Viewfinder modes.

For the args argument, you can provide one or more property-value pairs using camera_imgprop_t values as the name of the property and the correct type for the value such as an int or double value. The following camera_imgprop_t can be used with this function:

There is no type-checking performed by the compiler, therefore, you must ensure that the value you provide for each property matches the expected data type. Data type mismatches can result in undefined behavior and may cause your application to crash.

You can specify multiple property-value pairs by delimiting them with a comma as follows:
 camera_set_videovf_property( camera_handle,
                              CAMERA_IMGPROP_WIN_GROUPID, "mygroup",
                              CAMERA_IMGPROP_WIN_ID, "vfwindow",
                              CAMERA_IMGPROP_WIDTH, 720,
                              CAMERA_IMGPROP_HEIGHT, 1280,
                              CAMERA_IMGPROP_ROTATION, 270,
                              CAMERA_IMGPROP_FRAMERATE, (double)30.0 );

The following properties can't be changed while the viewfinder is running:

Returns:

CAMERA_EOK when the function successfully completes, otherwise another camera_error_t value that provides the reason that the call failed.
