Command

A command is a single action necessary for a recording job. A typical recording job consists of a sequence of command to control the source devices, routers and video recording devices involved. Additional commands like the starting of workflows are also possible.

Everything needed for execution is stored in the command.

As commands are only used for the execution in VidiControl there is no representation for them in VidiCore.

Properties

Property

Possible Values

Example

Description

Writeable?

id

string

0B

External ID of the Command.

Read only (Created by VidiControl).

capabilityId

string

pY

Capability which should be executed (e.g. switch capability of router)

Read and Write.

poolId

string

GD

External ID of the pool the device that executes the command must be assigned to.

If a device is needed to execute the command either this or deviceId must be set.

Read and Write.

deviceId

string

2n

External ID of the device that will execute the command.

If a device is needed to execute the command either this or poolId must be set.

Read and Write.

executionTime

string (DateTime using the universal sortable date/time pattern)

2023-01-06T14:04:44.799Z

The planned execution time of this command.

This must be set for recording commands. For other commands it is calculated in a manner that ensures everything is ready for the recording when it starts.

In general Read and Write.

Depending on the type of command and the other commands of the Chunk, some execution times are overwritten with calculated values.

duration

long >= 0

If null, 0 is assumed.

3600

Execution duration of the command in seconds.

This is used to plan the execution time of the commands around e.g. the recording command, block devices etc.

Read and Write.

index

long

1

Position of this command in the chain of commands.

This is relevant for the calculation of command execution times.

Read and Write.

executionState

string

(“Pending”, “InProgress”, “Done” or “Error”)

Pending

Current status of the command

Read only.

handling

string

(“WaitForResult” or “FireAndForget”)

FireAndForget

Defines how the command execution is handled regarding to the following commands.

This has consequences for the calculation of the other commands' execution times.

WaitForResult: The following commands are started after this command is finished at the earliest.

FireAndForget: The following commands can be started directly after this command is started.

Read and Write.

content

string (JSON)

JSON
{
  "action":"Record",
  "input":
  {
    "targetPath":"path",
    "profileName":"profile01"
  }
}

The action and action specific information needed for the execution of the command.

As the actions are very diverse, their parameters are too. This is represented by using an action specific structure in the input field.

Read and Write.

commandType

string

(“Workflow”, “CapabilityRecorder”, “CapabilityRouter”, “CapabilityUnknown”)

CapabilityRecorder

The higher level command type.

A command type can include multiple actions and capabilities.

Depending on this, VidiControl behaves slightly different regarding content format evaluation, device utilization etc.

This should fit the action and capability of the command in any case. Otherwise unwanted behavior cannot be ruled out.

Read and Write.

inPortId

string

aN

Meaning differs regarding to the command type:

Router-Command: In-port for the router switch

Recorder-Command: In-port of the router switch used for the recording command, set by VidiControl automatically

Router-Command: Read and Write

Recorder-Command: Read only.

outPortId

string

8l

If the command is a router command, this represents the out-port for the router switch.

This field is calculated by VidiControl.

Read only.
