| 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. | |

| 73 | appropriately. The generic error codes are described at the | |
| 74 | :ref:`Generic Error Codes <gen-errors>` chapter. |
