WVR_EXPORT WVR_Result WVR_GetFrameRate(uint32_t * frameRate)

Function to get rendering frame rate.

Use this function to get rendering frame rate. This function must be called after calling WVR_RenderInit().

API Level 12
Supported since Runtime version 12 or higher.
  • frameRate: A pointer to an unsigned integer of current rendering frame rate.
Return Value
  • WVR_SUCCESS: Get frame rate success, otherwise returns false.
  • WVR_Error_RuntimeVersionNotSupport: This feature is supported from Runtime version 12 or higher.
  • WVR_Error_FeatureNotSupport: This feature is not supported on this device.
  • WVR_Error_SystemInvalid: The runtime initialization was not finished.
  • Others: Failed, please see WVR_Result for more information.

How to use

Here is an example for the function:

uint32_t frameRate;
LOGI("Current render target frame rate: %d", frameRate);


  • This function will return the render target frame rate, not the current rendering FPS.
  • If you call WVR_GetFrameRate to get current render target frame rate right after the WVR_SetFrameRate, it will get the previous render target frame rate, since the system need to take some processing time to make the frame rate change effective after WVR_SetFrameRate calling.
