OnTheAir Video REST API

OnTheAir Video's REST API allows you to retrieve OTAV's status, change playlists, do controls of the playback and playing with the DGO. Also note that this REST API is not final, it's a first draft and there could be changes in the future when it is finalised.

This API is meant to be RESTful, then, using different verbs on requests leads to different behaviour on request processing.
In general manner, consider theses verbs to have the described behaviour:

    GET -> Retrieve data of a processable entity.
    POST -> Create a new entity.
    PUT -> Update a specified entity.
    DELETE -> Delete an entity.

When you modify or retrieving data, be sure to handle properly the return code that is returned by the API as it indicates if the operation was successfull or not.
For POST & PUT requests you MUST supply the 'Content-Type' header with value 'application/json'.
Here is a short list common codes returned by the API:

Code Meaning Description
200 OK The request was succesfully processed.
201 Created A new resource has been created on server side.
202 Accepted The resquest was accepted but was not processed.
400 Bad Request The resquest was not well formed.
401 Unauthorized The request needs an access token to proceed. See Authorization
403 Forbidden The token provided doesn't have sufficient privileges/permissions. See Authorization
404Not found The resquest couldn't be processed. The path is not recognized.
422 Unprocessable entity The resquest is well formed but is sementically incorrect

To know if your request succeded; command, update, create and delete requests are followed with this kind of response:

Command response object:

{
    "success" : boolean,
    "error" : string OPTIONAL
}

"success": Indicates if the request was accepted and processed or not by OnTheAir Video.
"error": In case of success false, indicates what was wrong when processing the request.


NOTE:
OPTIONAL marked parameters indicates that these parameters can be or not be present in the response object, this is due to internal logics.
However for requests that require a body, like PUT or POST, it means that it can be passed but they are not mandatory.



Authorization

Since playlists can play sensitive content at a time, an authorization mechanism will be required if you decide to enable it in OnTheAir Video's preferences. (General -> HTTP Server -> Require Authentication).

If this feature is enabled, it implies that you have to login with one of the registred user defined in OnTheAir Video and use the token received. In case not, you can ignore this section.

Each user has an access level, it defines how much control you have.
Theses are described as follows:

# Title Description
1 Read Only You'll only be able to retrieve informations but not modifying it.
2 Modify Playlists You'll only be able to modify playlists.
3 Modify And Control Playlists You'll be able to modify playlist, control the playback and DGO.
4 Full Access You'll be granted to execute all commands (admin privileges).

In order to make request you must first login with the following request:

PUT /authorize
{
    "username": string, REQUIRED
    "password": string REQUIRED
}

Response:
{
    "token": string, OPTIONAL
    "error": string, OPTIONAL
    "level": number
}

The token received MUST be added in the query parameter of each request you make to OTAV.
The level property is indicating the level granted to the logged user as defined in the table above.

NOTE:



Unique id - index or display name ?

Each playlist can be addressed using either its unique_id or its index.

Each clip can be addressed using either its unique_id, its index or eventually its display name.

Each action can only be addressed by its unique_id.

Playback Controls

Types of controls

You have three ways to control the playback. Depending on what you want to achieve, you can:

  • address "playback" and NOT specify a playlist, nor a clip. In this case, the playing playlist (or the front one if no playlist is playing) will be the one answering your requests.
  • specify the playlist you want to control (by using its index or unique ID), but without specifying a clip. In this case you can start the playback on a specific playlist, and the first clip (or the playing one) in the playlist will be controlled
  • specify both the playlist you want to control, as well as the clip (by using their index or unique ID). That's the way to start playing a specific clip in a specific playlist.

NOTE:
When using playback commands (play or pause) by specifying a clip, the following parameters can be passed in the URL to set the playback's play head at a precise timecode:

"position_relative_timecode": string HH:MM:SS:FF timecode position from the clip's start
"position_media_timecode": string HH:MM:SS:FF absolute timecode in the media
"position_relative_seconds": number position after x seconds from the media's beginning

Below, you will find the 3 types of controls (generic, per playlist or per clip). Depending on the type of command, you may have just one control possible. Or in some cases, all three are possible but will produce the same result. For example, if you aska a "generic" stop, it will do a stop the same way as if you specify a clip and/or a playlist.


The basic - play/stop/pause

Play

Start playing at the beginning of the front playlist:
GET /playback/play
Start playing at the beginning of the specified playlist:
GET /playlists/{n}/play
Start playing at the the specified clip of the specified playlist (see above to also specify an offset to start the clip):
GET /playlists/{n}/items/{m}/play
Response: command response object


Stop

All three requests will stop the playback, whatever playlist is playing.
GET /playback/stop
GET /playlists/{n}/stop
GET /playlists/{n}/items/{m}/stop
Response: command response object


Pause

If a playlist is playing or paused, the first 2 requests will control the "playing or paused" playlist: pause the playback if playing or resume it if paused. If nothing is playing, the first request will do a pause on the front playlist, on the selected clip if any. The second request will specify on which playlist the pause should be done.
GET /playback/pause
GET /playlists/{n}/pause
Even if something is playing or paused, the following request will ask to pause the clip. Never to resume it.
GET /playlists/{n}/items/{m}/pause
Response: command response object

Clear Next

If you want to clear the "Platy Next" clip that was set with the previous request, you don't need to indicate the playlist and clip. You can specify them if it's easier for your code, but they will be ignored.
GET /playback/clear_next
GET /playlists/{n}/clear_next
GET /playlists/{n}/items/{m}/clear_next
Response: command response object



Resume

As the pause control can either do a pause or resume, if you want to be sure to do a resume, you should use this one, instead of the pause... Whatever three requests, it will do a resume of the paused clip if any, in whatever playlist.
GET /playback/resume
GET /playlists/{n}/resume
GET /playlists/{n}/items/{m}/resume
Response: command response object



Skip to previous/next

Skip to next

All three commands will do a skip to next on the playing playlist... Nothing will happen if nothing is played or paused.
GET /playback/skip_next
GET /playlists/{n}/skip_next
GET /playlists/{n}/items/{m}/skip_next
You can also indicate if the skip to next should only be done if the currently playing item is a live (useful to exit a live, but ignore if you are already out of the live).
GET /playback/skip_next?live_only=1
You can also indicate if the skip to next should only be done if the currently playing item is a live (useful to exit a live, but ignore if you are already out of the live).
GET /playback/skip_next?live_only=1
Response:

{
    "success": boolean,
    "last_position": number Indicates the elapsed time of the previously playing clip in seconds.
}


Skip to previous

All three commands will do a skip to previous on the playing playlist... Nothing will happen if nothing is played or paused.
GET /playback/skip_previous
GET /playlists/{n}/skip_previous
GET /playlists/{n}/items/{m}/skip_previous
Response: command response object


Play next

Play next (clip)

Set which clip will play once the current one is done playing (or when doing a skip to next). This request only works when specifying a playlist and a clip.
GET /playlists/{n}/items/{i}/play_next
Response: command response object


Clear next (clip)

All three requests will clear the clip that was previously set as the next to play.
GET /playback/clear_next
GET /playlists/{n}/clear_next
GET /playlists/{n}/items/{m}/clear_next
Response: command response object


Other controls

GET /playback/gpi_trigger?input=1
Response: command response object


Join in progress

This feature is only available if you have the traffic option, will use the theoretical start date/time of the playlist and clip in order to start playing what was scheduled to play. The first request will do a join in progress, in the following order, on: the playing playlist; if no playlist is playing, the playlist of the day; if no playlist is playing, nor a playlist of the day is open, the front playlist
GET /playback/join_in_progress
The following two requests will do a join in progress on the specified playlist.

You can use the playlist index, or a unique ID (see above), same thing for the clip, you can use either the index or the unique ID.

There are 2 types of check:

  • A "simple" validation, "check for missing clips": we will compare the modification date of the file, and what we have stored in the playlist, and only validate the clip if the 2 are different. This is mainly useful when asking a whole playlist to check if clips have been modified or became online/offline
  • A "forced" validation: we will not check the modification date and force to validate the clip. This is to be used with care as it uses some resources (we have to open the file to get its info).

Check for missing clips

For the whole playlist:

GET /playlists/{n}/validate
Response: command response object

For a specific clip:

GET /playlists/{n}/items/{m}/validate

Get the list of actions of a playlist item

The following request will retrieve all the actions set on the item {m} of playlist {n}. You can use indexes, or unique IDs (see above).

GET /playlists/{n}/items/{m}/actions

Action response object:

{
    "name" : string, The name of the type of Action to execute. eg. "Execute AppleScript"
    "unique_id" : string, The unique identifier of the action.  eg. "0650A319-B0B7-4B06-957C-F81B38470548"
    "position" : number,position of the action in seconds. eg. 0
    "position_type" : string, 
position type
"position_timecode" : string, position of the action in timecode. eg. "00:00:00:00" HH:MM:SS:FF "template_id" : string,
type of action
"parameters" : array, will depend on the selected "template_id". See below for examples "is_outpoint_clamped" : boolean, * "is_inpoint_clamped" : boolean, ** "is_valid" : boolean, TRUE if the action is not valid (for example outside of clip boundaries) "is_offline": boolean, TRUE if the AppleScript action, or custom action file is not present on disk }

* TRUE if the Action is set to be triggered juste after the out point of the clip (less than 1 second after). Therefore, we have 'clamped' it so it will be triggered at the end of the clip.
** TRUE if the Action is set to be triggered juste before the in point of the clip (less than 1 second after). Therefore, we have 'clamped' it so it will be triggered at the end of the clip.


Get the info of a specific action on a playlist item

The following request will retrieve the action {k} set on the item {m} of playlist {n}. You can use indexes, or unique IDs (see above).

GET /playlists/{n}/items/{m}/actions/{k}
Response: array <playback response object>


Add actions to a clip

Previously, you just had to set a name of the AppleScript that had to be triggered for the action. Now you need to indicate the template_id, which is the type of action to execute. Then in its parameters, you set the attributes for that action. These parameters will be different depending on the type of action selected. This is why, we give some examples of actions below.

POST /playlists/{n}/items/{m}/actions
Body:
{
    "name" : string, OPTIONAL, eg. "Execute AppleScript" -> the name of the type of Action to execute
    "unique_id" : string, OPTIONAL, The unique identifier of the action. eg. "0650A319-B0B7-4B06-957C-F81B38470548"
    "position" : number, OPTIONAL, The position of the action in seconds. eg. 0 *
    "position_timecode" : string, OPTIONAL, The position of the action in timecode in HH:MM:SS:FF *
    "position_type" : string, OPTIONAL, 
position type
"template_id" : string,
type of action
"parameters" : array, OPTIONAL, will depend on the selected "template_id". See below for examples }

* When adding actions, you can specify 2 types of timing. Either using seconds (position), or using timecode (position_timecode). If you set both, it's the "position" (in seconds) that will be used.


Some examples of actions to add

As the parameter you will set will be different depending on the type of action, we are showing below some examples. But the easiest is for you to add actions in the OnTheAir Video playlist, and see the parameters that can be used.

Add an AppleScript Action

This actions will trigger an AppleScript (as the old actions). In parameters, you set the AppleScript to execute, and the "parameter" for that AppleScript (the string that can be used as a variable in the AppleScript).

POST /playlists/{n}/items/{m}/actions
Body:
{
    "position_timecode": string, OPTIONAL eg. "00:00:45:00"
    "position_type": string, OPTIONAL, 
position_type
"template_id": "AppleScript:Execute AppleScript" "parameters": { "AppleScript Name": string, The name of the AppleScript to execute "Parameter": string, OPTIONAL, The string that will be passed to be used in the AppleScript "After Delay (ms)": number, OPTIONAL, The delay to start the action in ms. eg. 0 }
Response: action response object


Add a Dynamic Graphics Overlay (DGO) action

This actions will control CG projects. The difference with the DGO control below is that when using Actions, you can set a specific time for the action to be triggered. If you want to control the status of the projects for the whole length of a clip, you may want to look below, in the section to control the DGO on a "per clip" base

POST /playlists/{n}/items/{m}/actions
Body:
{
    "position_timecode": string, OPTIONAL eg. "00:00:45:00"
    "position_type": string, OPTIONAL, 
position_type
"template_id": "Graphics:Start DGO Project" "parameters": { "Project Name": string, The name of the project to start. }
Response: action response object


Add a SCTE trigger action

This actions will output SCTE35 triggers in the SDI output (CC option required).

POST /playlists/{n}/items/{m}/actions
Body:
{
    "position_timecode": string, OPTIONAL eg. "00:00:45:00"
    "position_type": string, OPTIONAL, 
position_type
"template_id": "SCTE:Send SCTE Trigger" "parameters": { "Splice Type": string, The type of splice to do.
splice_type
"Event ID": number, OPTIONAL The number of the Event ID to. eg. 1 "Program ID": number, OPTIONAL The number of Program ID. eg. 1 "Duration (ds)": number, OPTIONAL The duration of the event in ds. eg. 0 "After Delay (ms)": number, OPTIONAL The delay to start the action in ms. eg. 0 }
Response: action response object


Add a Videohub Action

This actions will control a Blackmagic-Design VideoHub.

POST /playlists/{n}/items/{m}/actions
Body:
{
    "position_timecode": string, OPTIONAL eg. "00:00:45:00"
    "position_type": string, OPTIONAL, 
position_type
"template_id": "Routers:Videohub Switch" "parameters": { "IP Address": string, The IP address of the VideoHub "Source": number, OPTIONAL The number of the source to switch to. eg. 1 "Destination": number, OPTIONAL The number of the destination to control. eg. 1 "After Delay (ms)": number, OPTIONAL The delay to start the action in ms. eg. 0 }
Response: action response object


Modify an existing action on a clip

Once you have actions on a clip, you can use a PUT request to modify it. Just pass the keys that you want to modify. So if you need to modify the position, just pass the position key. You can usen either the index or the UID of the action. The UID is recommended so you are sure of which action you are modifying even if their order change.

PUT /playlists/{n}/items/{m}/actions/{k}
Body:
{
    "name" : string, OPTIONAL eg. "Display Finder Message" -> name of the AppleScript
    "position" : number, OPTIONAL eg. 0
    "position_type" : string, OPTIONAL
    "position_timecode" : string, OPTIONAL eg. "00:00:00:00" HH:MM:SS:FF
    "parameter" : string, OPTIONAL eg. Hello
}
Response: action response object


Delete actions

Delete a specific action of a clip

DELETE /playlists/{n}/items/{m}/actions/{k}
Response: command response object


Delete all actions of a clip

DELETE /playlists/{n}/items/{m}/actions
Response: command response object


Run an Apple script action on the go

The following request will run the mentionned apple script.

GET /actions/{name}/run?parameter={parameter}
Where :
{name} is the name of the action (the one you see on your folder)
{parameter} is the paramter you want to pass to that action

Warning: Use url percent encoded string if your action's name or parameter is using special characters (especially spaces) !

Response: command response object



Control the Dynamic Graphics Overlays "per clip"

In this section, you will see how to control the status of the DGO projects on a "per clip" base. In the OnTheAir Video preferences, you have to set a default status of a DGO project (running or stopped), which will be used if nothing is set on the clips. So it's very easy for example to have a project running by default, but then on a specific clip, to set the project to stop. This will be done for the whole duration of the clip. If you would like the project to start, or stop (or having its values modified) at a specific time in the clip, use actions instead.

Get the DGO projects:

Here are examples of requests to get the available CG projects or a specific project designated by {n}:

GET /playback/cg_projects
Response: array <CG Project object>

PUT /playback/cg_projects/{n}/items/{i}
Body:
{
    "htmlText": "<span style='font-family:Courier; color:red; font-size: 20;'> 20px red text. </span>
    <span style='font-family:Courier; color:blue; font-size: 50;'> 50px blue text.</span>"

Change Movies items

You can change the path of a movie item using either the full path or the relative path. When using the relative path, this means that the file used will be found relatively to the location of the project itself. This allows you then to move the project and media to another location, and this will continue to work. Of course this requires that the file be located in the same folder as the project.
PUT /playback/cg_projects/{n}/items/{i}
Body:
{
    "moviePath" : url, REQUIRED eg. using full path "/Volumes/Movies/MyMovie.mov"
}

Change Images items

PUT /playback/cg_projects/{n}/items/{i}
Body:
{
    "imagePath" : url, OPTIONAL eg. using relative path "../MyImage.jpeg"
}

Change Audio items

PUT /playback/cg_projects/{n}/items/{i}
Body:
{
    "filePath" : url, OPTIONAL eg. using relative path "../MySound.AIFF"
}
