Control a FireWire VTR Communicates with FireWire VTR devices, such as digital cameras and DV decks, using the 1394 AV/C protocol. Use it to control the transport of these devices with messages. Cycling '74 Jitter Jitter Devices messages in TEXT_HERE messages in TEXT_HERE dumpout TEXT_HERE Close the AV/C connection Closes the AV/C connection. The connection is closed automatically if the object is deleted, or the patch containing the object is closed. Send a custom string of data Sends a custom string of data to the DV device. Messages are usually sent as a sequence of hexadecimal numbers. Accepted messages are documented by the 1394 Trade Association . The relevant specification is the "AV/C Tape Recorder/Player Subunit". Fast rewind the transport Fast rewinds the transport. Fast forward the transport Fast forwards the transport. Report the device name Sends the name of the currently active device out the right outlet of the object in the form device active-device. Report the device time Sends the name of the currently active device out the right outlet of the object in the form time DVdevicemedia-time. Report the device transport state The gettransport message will report the precise state of the transport of the VTR device to which it is connected out the right outlet of the jit.avc object. Open an AV/C connection Opens an AV/C connection to a compatible device if one can be found. Pause the transport playback Pauses the transport playback. Set playback with options Sets playback at normal speed. The following optional arguments are permitted:
pause: Pause in playback.
reverse: Playback at normal speed in reverse.
revpause: Pause in reverse playback.

fr1: Playback at slowest fast reverse special effect speed Set the DV device to record Sets the DV device to record. The following optional arguments are permitted:
recpause: Pause while recording all signal(s)
insertvideo: Replace the video signal with a new signal, but leave any other signals on the medium intact
insertaudio: Replace the audio signal with a new signal, but leave any other signals on the medium intact
insertav: Replace the audio and video signals with new signals, but leave any other signals on the medium intact
insertsubcode: Replace the subcode signal with a new signal, but leave any other signals on the medium intact
insertvideopause: Pause recording signals, and set the recording mode record insertvideo
insertaudiopause: Pause recording signals, and set the recording mode record insertaudio
insertavpause: Pause recording signals, and establish the recording mode record insertav
insertsubcodepause: Pause recording signals, and set the recording mode record insertsubcode Pause while recording Pauses while recording all signal(s). Rewind the transport Rewinds the transport. Halt the transport Halts the transport. Seek to a specified time Causes the attached DV device to seek for the specified time on any loaded media. Time is specified by four integer arguments that specify hours, minutes, seconds and frames. Many devices do not support this function.
