cue device InOutTo flags
Flag that prepares a device for playing or recording. The following table lists device types that recognize the cue command and the flags used by each type:
digitalvideo | input
noshow |
output
to position |
vcr | from position
input output |
preroll
reverse to position |
waveaudio | input | output |
The following table lists the flags that can be specified in the InOutTo
parameter and their meanings:
from position | Indicates where to start. |
input | Prepares for recording. For digital-video devices, this flag can be omitted if the current presentation source is already the external input. |
noshow | Prepares for playing a frame without displaying it. When this flag is specified, the display continues to show the image in the frame buffer even though its corresponding frame is not the current position. A subsequent cue command without this flag and without the “to” flag displays the current frame. |
output | Prepares for playing. If neither “input” nor “output” is specified, the default setting is “output”. |
preroll | Moves the preroll distance from the in-point. The in-point is the current position, or the position specified by the “from” flag. |
reverse | Indicates play direction is in reverse (backward). |
to position | Moves the workspace to the specified position. For VCR devices, this flag indicates where to stop. |
This command fails if playing or recording is in progress or if the device is paused.
When cueing for playback (using cue “output”), issuing the play command with the “from”, “to”, or “reverse” flag cancels the cue command.
When cueing for recording (using cue “input”), issuing the record command with the “from”, “to”, or “initialize” flag cancels the cue command.
The following command prepares the “mysound” device for recording:
