camera_set_videovf_property()

#include <camera/camera_api.h>
 

camera_error_t camera_set_videovf_property(camera_handle_t handle, args...)

Arguments:

handle

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

args...

A property-value pair delimited by a comma. The property name and property value must also be delimited by a comma.

Library:

libcamapi

Description:

As part of 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:

• CAMERA_IMGPROP_WIN_GROUPID
• CAMERA_IMGPROP_WIN_ID
• CAMERA_IMGPROP_FORMAT
• CAMERA_IMGPROP_WIDTH
• CAMERA_IMGPROP_HEIGHT
• CAMERA_IMGPROP_FRAMERATE
• CAMERA_IMGPROP_ROTATION
• CAMERA_IMGPROP_HWOVERLAY
• CAMERA_IMGPROP_ZOOMFACTOR
• CAMERA_IMGPROP_MAXFOV

You can specify multiple property-value pairs by delimiting them with a comma as follows:

 name1, value1, name2, value2,...

For example, you can set values in the following manner:

 camera_set_videovf_property( camera_handle,
                              CAMERA_IMGPROP_WIN_GROUPID, "GroupID",
                              CAMERA_IMGPROP_WIN_ID, "WindowID",
                              CAMERA_IMGPROP_WIDTH, 1024,
                              CAMERA_IMGPROP_HEIGHT, 576,
                              CAMERA_IMGPROP_ROTATION, 90,
                              CAMERA_IMGPROP_FRAMERATE, (double)30.0 );

Note: The following properties can't be changed after the viewfinder has started:

• CAMERA_IMGPROP_WIN_ID
• CAMERA_IMGPROP_FORMAT
• CAMERA_IMGPROP_HWOVERLAY
• CAMERA_IMGPROP_MAXFOV You can change these properties after stopping the viewfinder. When the viewfinder is running then CAMERA_IMGPROP_WIN_GROUPID can only be set if the current value is an empty string.

Returns:

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