What is the Vistar app?
The Signagelive Vistar application is an integration with the Vistar Media ad service platform which allows you to serve image and video content from Vistar Media to your Signagelive players.
Please NoteTo be able to use the Vistar application within Signagelive you will need a Vistar account to be able to proceed. Further information on Vistar can be found here.
What are the supported players and features?
The Signagelive Vistar application works on players supporting the Signagelive Widget SDK, which are Samsung Tizen, LG webOS, Electron (Windows) and BrightSign at this stage. Note release dates for some of those are in the near future and we’ll be adding support for more players in 2022.
The Signagelive Vistar application can serve images and videos with no audio, however LG webOS 1.0, LG webOS 2.0 and Samsung Tizen 2.4 players can only serve images at this stage due to hardware and software restrictions:
Please NoteThe minimum recommended firmware version for Brightsign players is 8.2.72. Please check our BrightSign Tips and Tricks page for instructions on upgrading the firmware.
Please also note that only MP4 videos using the well known H.264 video codec are supported; unsupported video codecs should still not be used on the Vistar platform as we have no way of excluding these from attempting to play. If it is attempted Signagelive will crash or the player will become unresponsive. Note that audio is not supported, therefore audio in videos can’t be played.
How do I use the Vistar app?
The setup of the Vistar application has two separate components, which are:
- A widget that syncs and does all the asset caching, called Vistar Caching App.
- A display widget that queries Vistar for an available ad slot and then plays the correct ad for that slot using the cached assets, called Vistar Display App.
Vistar Caching App
This app syncs with the Vistar Platform to dynamically retrieve all valid ads every hour and then cache them to storage. This app will need to run with the contents stored to the cache before starting ad playback; and this then therefore allows seamless transitions on supported media players. The app caches any valid assets for the next 30 hour period.
In Signagelive, the Vistar Caching App needs the following preferences:
- Network ID - this is determined by your Vistar Media account
- API ID - this is determined by your Vistar Media account
- Venue ID - this is determined by your Vistar Media Orders and Venues currently setup
These properties can be set by double clicking the Vistar Caching App on your playlist in Signagelive, then clicking the Properties tab. The Venue ID can also be referenced on the media player as reference code 2. To do so open the player details, click on the Player Site and Contact Details tab, enter the Venue ID on the Reference 2 field and save the details.
Vistar Display App
This handles the visual side of displaying the retrieved ad (video or image) and sending the proof of play or expiry callback depending on whether it has succeeded or failed.
Instructions to setup Vistar apps for publication:
At a high level, the Vistar Caching App must be run before the Vistar Display App. The caching app must have a suitable asset duration to allow the ad media to be downloaded and stored to the player, otherwise this will mean that if the display app tries to play an ad that is not cached, it will send an Expiry response back to Vistar’s API. In that instance, the Caching app will need to be run again and the Display widget will transition to the next asset in the playlist if it does not have a valid asset to play.
If you’re looking to publish Vistar media content in a fullscreen playlist, add the Vistar Caching app to a new playlist with a duration long enough to cache all files from Vistar, specially for the first playlist loop. Then add the Vistar Display App next, it is preferred to set a longer asset duration; as once a Vistar Media ad has finished playing it will automatically transition to the next asset in the playlist.
Please NoteIt is not recommended to use the Vistar Display app as the only media asset in a schedulable playlist
For more information on fullscreen content, please check our Playlists - Beginner Techniques section.
If you’re looking to publish Vistar Media content in a multi zone layout, our recommendation is to use a layout with two schedulable zones with identical sizes and coordinates within the canvas. One zone will be behind the other as a result.
For more information on layout creation, please check our Layout - Beginner techniques section.
Each schedulable zone will contain a different playlist, which will be assigned on the publishing stage. The first playlist will contain the Vistar Caching App and the second playlist will contain the Vistar Display App.
When publishing, add the playlist containing the Vistar Display App to the schedulable zone on the front, then add the playlist containing the Vistar Caching App to the schedulable zone on the back. This will create the setup required above, running both apps at the same time.
