HTTP Remoting Service

Remoting over HTTP

Version 6 comes with a VMS module that makes the Remoting4 OSC protocol transparent to HTTP / HTTPS

Session Service

Ventuz Runtime and Ventuz Designer hook this service into the VMS as a dynamic module. So in combination with the Session Service you can easily achieve a launch and a shutdown of the Runtime and/or access the Designer. See projects and publish contexts here: http://localhost:21404/vms_session_service/1.0

Start Project

To launch Ventuz Runtime with a project (here 0c31bb73-f9e1-430f-909f-e3a985adf41a) request this URL:

http://localhost:21404/vms_session_service/1.0/projects/0c31bb73-f9e1-430f-909f-e3a985adf41a/action/start

Additional command line arguments can be passes as query fields.

http://localhost:21404/vms_session_service/1.0/projects/ lists all available projects

Start Publish Context

To launch Ventuz Runtime with a Ventuz Publish Context (here 62a7b420-99ca-4704-8848-1e804ca4cff0) use this URL:

http://localhost:21404/vms_session_service/1.0/publishcontexts/62a7b420-99ca-4704-8848-1e804ca4cff0/action/launch?-warmup

Additional command line arguments can be passes as query fields. The argument -warmup will load all scenes specified in this context and cues all templates for two frames.

http://localhost:21404/vms_session_service/1.0/publishcontexts lists all available publish contexts

HTTP Remoting Service

Please have this notes in mind:

Every HTTP/S request is a blocking call
Every HTTP/S request will establish a new TCP connection (as of today), so using HTTPS might be slow!
Responses are usually formatted as JSON parse-able text
Async responses like log message or status changes can not be received

Requests

A request URL always start with the service address:

http://localhost:21404/remoting/1.0/Remoting4

This URL is directly extended by the OSC command address described in the Remoting4 documentation. The command /Ventuz/Info is issued by requesting this URL:

Request: GET http://localhost:21404/remoting/1.0/Remoting4/Ventuz/Info

Response: (example)

{
  Ventuz: {
    Version: "6.0.0.128",
    Edition: "Ventuz 6.0 V6.0.0 128 R21772",
    Mode: "Designer"
  },
  Machine: {
    Name: "DESKTOP-NSJ5IPI",
    ID: 0,
    GroupID: 0,
    ProcessID: 18508,
    ProcessGUID: "2838e71e-6c22-4c5b-b7d6-cee37a4db194",
    SystemID: "VZ_M80-55022900324_BFEBFBFF000306F2_00330-80109-59023-AA022",
    Rate: [ 59954, 1000 ],
    Pipes: [ "Graphics" ]
  },
  Project: {
    Title: "Hockey",
    ID: "15e6698c-7726-4be1-9ede-3ee1c58d9006"
  },
  PublishContext: null
}

Arguments

The HTTP protocol accepts two different methods:

GET arguments / parameters have to be encoded into the query fields of the request URL
POST arguments / parameters are passed as multi-part-form-data

In both methods the arguments have to be formatted in the order as described in the Remoting4 documentation as JSON parse-able text. The argument RequestID have to be omitted.

Example:

Request: http://localhost:21404/remoting/1.0/Remoting4/0000/Load?3dmask&1

SceneIdentity = 3dmask
LoadFlags = 1

Response:

{
  IID: "FTKT",
  IsNew: true
}

Responses

Simple responses are transferred as JSON values or arrays. Complex responses are returned as JSON objects (dictionaries)

The /0000/Snapshot command is an exception: it delivers a binary response containing the image on success.

http://localhost:21404/remoting/1.0/Remoting4/0000/Snapshot?1&0&0&0&0&0&0&0&true

Errors

Request: http://localhost:21404/remoting/1.0/Remoting4/0000/ThisIsNoCommand

Response:

{
  ErrorCode: 501,
  Error: 501,
  Message: "Unknown or invalid address /0000/ThisIsNoCommand",
  Details: "Method 'Ventuz.Kernel.CModel.Remoting4Server+Session.Request_IID_ThisIsNoCommand' not found."
}

Request: http://localhost:21404/remoting/1.0/Remoting4/0000/Load?unknownscene

Response:

{
 ErrorCode: 404,
 Error: 404,
 Message: "Load failed",
 Details: "Remoting2: unknownscene: Could not find file 'D:\PROJECTS_TIMELINE\NAB_Eishockey\Scenes\unknownscene.vzs'.: 
Invalid Scene"
}

Returned error codes are also described in the Remoting4 documentation.

Extra Commands

The Remoting via HTTP protocol has extra command:

Switch Project

/Ventuz/SwitchProject with one argument:

filename_or_guid where guid is a project or a publish context id

Switches the current project or publish context. Unloads all scenes, resets renderer and load another project

Play Template

Version 6.00.xx

/0000/00/Play with two arguments:

options (int), same options as the Cue command
data (string), template data or URL or empty string

Cues and Takes a template. This is actually a combination of the Cue and Take command with sync execution. This makes it very easy to bring template based graphics on-air without maintaining complex communication. Using an empty string for data issues a cue-out on the specified port (here port 00 of pipe 0000). Options are the same values for the Cue command. See TransitionOptions in the Remoting4 documentation.
