^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) This ioctl is obsolete. Do not use in new drivers. For V4L2 decoders
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) this ioctl has been replaced by the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) :ref:`VIDIOC_DECODER_CMD` ioctl.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56) This ioctl commands the decoder. The ``video_command`` struct is a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) subset of the ``v4l2_decoder_cmd`` struct, so refer to the
