|int request||Equals VIDEO_FREEZE for this command.|
This ioctl is for Digital TV devices only. To control a V4L2 decoder use the V4L2 ioctl VIDIOC_DECODER_CMD, VIDIOC_TRY_DECODER_CMD instead.
This ioctl call suspends the live video stream being played. Decoding and playing are frozen. It is then possible to restart the decoding and playing process of the video stream using the VIDEO_CONTINUE command. If VIDEO_SOURCE_MEMORY is selected in the ioctl call VIDEO_SELECT_SOURCE, the Digital TV subsystem will not decode any more data until the ioctl call VIDEO_CONTINUE or VIDEO_PLAY is performed.
