Webradio - High CPU usage by web browser

[andfor]

HI,

I have just noticed a strange issue when running Rune UI through a web-browser. If I am listening to a radio station the web browser will sometimes show nearly 25% CPU utilization. This happens when the browser is open on the Playback page. For most stations, If I refresh the UI this drops to around 2%.

There are some stations that won't display the radio 'album art', just the place-holder Rune symbol. Refreshing the UI on these stations does nothing, CPU still 25%.

I am using Firefox. I am using a modified version of Rune 0.4b on an Rpi3. I have altered the UI files to my own liking, mostly cosmetic, but I did change the behaviour of selecting radio stations to a single-click 'Add, Replace and Play' (see: radio-stream-selection-t5746.html).

Any help tracking down the cause of this would be appreciated.

Many thanks.

Hi andfor,

please open the developer console on your Firefox browser and check for errors.

Hi,

I was just wondering if there was any opinion as to what is happening here? The problem seems to be with navigating to the Playback screen using the 'Playback' button along the bottom bar. This doesn't reload the page (like selecting 'Playback' from the dropdown menu does) so my best guess is that it's something to do with the progress wheel attempting to treat an infinite radio stream like a music file that has a finite length.

Anyway, I don't have the technical proficiency to follow the errors and debug this so any help or insight would be welcome.

Many thanks

No ideas?

I realise nobody wants to chase rabbits down holes on my behalf, but any pointers as to what might be happening would be appreciated. Where do I start? And does anyone else see the same behaviour? Is it present on a stock install? (I have modified mine).

It's not a huge deal because I can just reload the page every time I select a radio stream to bring down the CPU usage, but that is a bit annoying.

Thanks again.
