61 | This ioctl is for DVB devices only. To control a V4L2 decoder use the | |
62 | V4L2 :ref:`VIDIOC_DECODER_CMD` instead. | |
63 | ||
64 | This ioctl call asks the Video Device to stop playing the current | |
65 | stream. Depending on the input parameter, the screen can be blanked out | |
66 | or displaying the last decoded frame. | |
