61 | ----------- |
| 62 | ||
| 63 | This ioctl is for DVB devices only. To control a V4L2 decoder use the | |
| 64 | V4L2 :ref:`VIDIOC_DECODER_CMD` instead. | |
| 65 | ||
| 66 | This ioctl call asks the Video Device to stop playing the current | |
| 67 | stream. Depending on the input parameter, the screen can be blanked out | |
| 68 | or displaying the last decoded frame. | |
| 69 | ||

| 74 | On success 0 is returned, on error -1 and the ``errno`` variable is set | |
| 75 | appropriately. The generic error codes are described at the | |
| 76 | :ref:`Generic Error Codes <gen-errors>` chapter. |
