Videos App to play the video of the videos app

This app supports playing videos using the OVE framework. It provides a generic player for any video (HTML5), a player for tiled videos in an .OTV format, and a player based on the YouTube IFrame Player API (YouTube).

Seen above is a video of the videos app playing the YouTube video in 4K resolution published by the Wikimedia Foundation recorded in HD resolution at the Imperial College Data Science Institute’s Data Observatory.

Application State

The state of this app has a format similar to:

    "url": ""

The player is selected automatically based on the URL: Any YouTube URL uses the YouTube player, any URL for a file with an .otv extension uses the tiled video player, and all other URLs use the HTML5 player. By default, all videos will play muted. An optional property, unmuted can be set to true to play videos unmuted.

Launching the App

All OVE applications can be launched using the Launcher UI, the Python Client Library, and the OVE APIs. The API used to launch an application is the same for all applications, but the data that is passed into it is application-specific.

To launch the SVG app and load a video using the OVE APIs:


curl --header "Content-Type: application/json" --request POST --data '{"app": {"url": "http://OVE_CORE_HOST:PORT/app/videos","states": {"load": {"url": ""}}}, "space": "OVE_SPACE", "h": 500, "w": 500, "y": 0, "x": 0}' http://OVE_CORE_HOST:PORT/section


curl --header "Content-Type: application/json" --request POST --data "{\"app\": {\"url\": \"http://OVE_CORE_HOST:PORT/app/videos\", \"states\": {\"load\": {\"url\": \"\"}}}, \"space\": \"OVE_SPACE\", \"h\": 500, \"w\": 500, \"y\": 0, \"x\": 0}" http://OVE_CORE_HOST:PORT/section

Controlling the App

The controller of the app can be loaded by accessing the URL http://OVE_CORE_HOST:PORT/app/videos/control.html?oveSectionId=SECTION_ID.

The app’s API also exposes operations such as play, pause, stop, mute, seekTo and bufferStatus. These operations can be executed on a per-video basis or across all videos.

To play videos using OVE APIs:

curl  --request POST http://OVE_CORE_HOST:PORT/app/videos/operation/play

Instructions on invoking other operations are available on the API Documentation, http://OVE_CORE_HOST:PORT/app/videos/api-docs/#operation.
