Title: JSONPlayer - Automatic Updates?
Post by: mjones1040 on April 13, 2017, 11:10:28 AM
I have a JSON Player on my timeline which is being used to display prices. These are all fed via a service running on the point of sale which generates a JSON file with the prices on demand. Is there any way to get the JSON Player to automatically check for changes and update?

We have already tried setting the JSON Player to run for a shorter duration - 10 minutes - which does work, but this creates a situation where the prices fade out and then come back. Having the prices disappear and then reappear every time it updates, even if there are no changes, isn't an acceptable solution for us. Is there way to check for changes and only refresh the display when there are changes?

Thanks

You can put the json player on a common channel so it does not restart

So here are my new settings. I added a common channel.

Random order: OFF
Repeat to fit: ON
Respect content length: ON

JSON Player:

URL: 192.168.100.100:4525
Items path: channel.item
SlideShow: OFF
Order (Random): OFF
Interval (Play videos to completion): OFF
Transition pool: None
Duration: 1 minute


The problem now is that it isn't updating the information. So no more flicker, but also no update when prices are changed.

Hi,
I agree with Mjones. It would be great if json player could update itself without reloading a whole scene.

we can add this functionality once release 6.0 is out, due later this summer.

Any updates on this?

The flicker cant be avoided because this is caused by the mechanism that checks for updates on the json data,  in the common channel scenarios slideshow needs to be enabled as well as intervals set for the json player to check for updated data.
