14 .. attention:: This ioctl is deprecated.
19 .. c:function:: int ioctl(fd, VIDEO_FREEZE)
35 - File descriptor returned by a previous call to open().
41 - Equals VIDEO_FREEZE for this command.
47 This ioctl is for DVB devices only. To control a V4L2 decoder use the
48 V4L2 :ref:`VIDIOC_DECODER_CMD` instead.
50 This ioctl call suspends the live video stream being played. Decoding
51 and playing are frozen. It is then possible to restart the decoding and
52 playing process of the video stream using the VIDEO_CONTINUE command.
53 If VIDEO_SOURCE_MEMORY is selected in the ioctl call
54 VIDEO_SELECT_SOURCE, the DVB subsystem will not decode any more data
55 until the ioctl call VIDEO_CONTINUE or VIDEO_PLAY is performed.
61 On success 0 is returned, on error -1 and the ``errno`` variable is set
62 appropriately. The generic error codes are described at the
63 :ref:`Generic Error Codes <gen-errors>` chapter.
