get_supported_vf_framerates_func

Retrieve the list of supported viewfinder framerates

Synopsis:

#include <camera/external_camera_api.h>

typedef int(* get_supported_vf_framerates_func_t)(void *handle,
            camera_res_t *resolution,
            camera_frametype_t frametype,
            int *numRates,
            bool *isMaxMin,
            float *rates);

Arguments:

handle: The handle that's returned from calling the function open_external_camera_func_t.
resolution: The resolution associated with this query.
frametype: The frame type associated with this query
numRates: Needs to be set to the number of viewfinder framerates supported.
isMaxMin: Need to be set to true if the rates provided represents a range of value between a minimum and a maximum; need to set to false if the rates provided represent the list of individual rates supported.
rates: Array to fill with the supported framerates; if isMaxMin is set to true, use array index defined in camera_vf_framerate_min_max_index_t for the minimum and maximum values; if isMaxMin is set to false, set the individual framerates that are supported up to 100 entries.

Library:

libcamapi

Description:

The viewfinder is capable of operating at different framerates. This function retrieves the list of supported framerates for the specified camera for a given frame type and resolution. Note that the fractional precision of each supported framerate shouldn't exceed 3 digits of precision.

Returns:

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