Arguments
---------
.. flat-table::
:header-rows: 0

- .. row 1
- int fd
- File descriptor returned by a previous call to open().
- .. row 2
- int request
- Equals VIDEO_GET_FRAME_RATE for this command.
- .. row 3
- unsigned int \*rate
- Returns the framerate in number of frames per 1000 seconds.
Description
-----------
This ioctl call asks the Video Device to return the current framerate.
Return Value
------------
On success 0 is returned, on error -1 and the ``errno`` variable is set
appropriately. The generic error codes are described at the
:ref:`Generic Error Codes <gen-errors>` chapter.

A call to VIDEO_SET_SYSTEM sets the desired video system for TV
output. The following system types can be set:

Calling the ioctl VIDEO_SET_HIGHLIGHTS posts the SPU highlight
information. The call expects the following format for that information:
