Feature Request: Stop calling /Sessions/Playing/Progress indefinately

[stephen_hill 35]

Hi

Please can you update all of your clients so that the endpoint /Sessions/Playing/Progress is not called indefinitely.

I have observed this behaviour on the Web Interface, Android, and iOS.

When a client pauses a piece of media, the client will call the /Sessions/Playing/Progress endpoint indefinitely (at a rate of 1-5 seconds) with the exact same "TimeUpdate" parameter. If the client calls the endpoint and the TimeUpdate parameter has not changed (ie paused) the client should not call it again until progress on the media has changed.

Here is an example server log line that gets repeated indefinitely

Reasons for wanting this are:

• Reduces network traffic
• Reduce power consumption on mobile devices
• Stop filling the server logs with repetitive lines

Hi, it’s actually ten seconds. It’s how the server knows the client is still around. But yes there’s room for improvement.

@Luke

According to my logs it's ever 5 seconds.
