Description Or Schiro 2018-09-03 13:48:50 UTC

Dear all, 

Thank you for this great integration for Chrome!

Finally a way to control media playback reliably. :-)

I heard I could even use it on GNOME. 

So I installed it on Fedora 28 and it works very reliably on YouTube with Chrome. 

I can press Fn + F11 to play/pause playback. 

However, it does not always work with this radio:

https://tunein.com/radio/Classic-FM-1009-s8439/

Sometimes, like now, it works and I can play/pause. 

Sometimes, however, pressing the shortcut would do nothing. 

Is there anything I can do to improve the reliability with this radio site?

Does anyone have similar issues on this website?

Thank you!

Yours, 

Robert

I can confirm it doesn't work on this site. Apparently there is also a "video" element on that page which it ends up controlling.
Controlling the audio player manually from developer console works.

An approach I thought about could be to ignore signals from <video> elements that aren't part of the DOM since you cannot see them anyway.
However, Spotify uses a <video> (rather than <audio>) for playing its music :(

Dear Kai, 

I found this [1] website to also not support the playback buttons on my keyboard. 

Can you confirm?

What's the best procedure to track sites that don't work properly?

Is it good to keep them all in one place (here), or better to open a new ticket for each page?

Yours, 

Robert

Thanks for your feedback! It's best if each issue is filed in a separate ticket as it is likely to be a different root cause every time.

The cinemix site uses JavaScript "Audio" instead of HTML5 <audio> tags which we currently don't support. It is not possible to pass JavaScript variables from the website to the extension script. The content script can access the DOM of the website and as such extract <audio> and <video> tags but I haven't found a way yet to pass pure-JS audio/video players around.

Thanks, Kai!
