play (VNM Recorder and VNR 100 devices only)
The
play
command starts playback of the specified player and channel number. All
associated streams (video, audio, data, whiteboard) start when the command is issued. A
playat
time can be included to start playback at a pre-defined system time in the future,
enabling the synchronization of multiple channels. In addition, an offset time can specify a
start point other than the beginning of the recording.
Command line structure (required parameters in bold):
play source:n playat offset
Available parameters and arguments for this command are:
Parameter Argument Description
source Device ID, IP address, or
name of the device.
:n
Channel number Defaults to channel 1 if not otherwise
specified.
playat hh:mm:ss.uuuuuu
Example:
13:23:25.123456
Future time based on the system controller
clock. Setting the same playat time
across multiple devices and channels allows
scalable playback synchronization.
offset nnn (seconds)
Example: 126
Allows playback from a position other than
the start of the recording.
For example, specifying a value of 126 starts
playback 2 minutes and 6 seconds into the
recording.
For the following examples:
VNR 100: Name = 100_Device1 , ID = 10001 , IP = 192.168.0.11
VNM Recorder: Name = 5ch_Device1 , ID = 50001 , IP = 192.168.0.51
Example 1 - Start playback on a VNR 100 device using the IP address.
play 192.168.0.11
]
Example 2 - Start playback on a VNR 100 device using the device name.
play 100_Device1
]
Example 3 - Start playback on a VNR 100 device 3 minutes into the recorded file.
play 100_Device1 offset= 180
]
Example 4 - Start playback at a system time of 15:12:22 on a VNR 100 device 3 minutes
into the recorded file.
play 100_Device1 playat= 15:12:22.123456 offset= 180
]
Example 5 - Start playback on channel 2 of a VNM Recorder using device ID.
play 50001:2
]
Example 6 - Start playback at a system time of 15:12:22 on channel 2 of a VNM Recorder.
play 50001:2 playat= 15:12:22.123456
