FV Player not playing YouTube vids on Mobile

Hello Bruce,

it appears your are stripping the query string versions from the JavaScript links. That means if there was a significany update in the core the users’ browsers won’t know about the change unless they clear their cache and reload.

There was a bug occuring when using FV Player 7.4.0.727 together with FV Player Pro 7.3.19.727 regarding YouTube videos on mobile. But since you are removing these query string versions you might not notice the fix whih we put in FV Player Pro 7.4.0.727 – it appears you updated to it already. But because of missing query string versions most people might be still getting the script from the old FV Player Pro version.

More on the topic of caching and query string versions can be found here: https://foliovision.com/2017/06/wordpress-cdn-best-practices

I was able to play the video on https://www.loveatfirstfight.com/fv-test/ without issues – probably because I haven’t visited your website before, so my browser is not hanging on to the old cached FV Player Pro script.

Thanks,
Martin

Hello Bruce,

1) Please forward that question to your web hosting support. You can also try to enable the “Remove query string from static resources” setting in WP Rocket. They actually do it properly and keep the version number in the URL. That way the version number wouldn’t be stripped by some further “optimization”. I put that into quotes as you won’t gain any speed by removing the query string versions.

2) FV Player gives you the video player and FV Player Pro adds advanced features to it, you need to use both.

Thanks,
Martin

Hello Bruce,

I’m not sure if you got the email notfication about my previous reply, please read it and you should find some helpful information there.

Thanks

Hi Bruce and Martin,

I hope that everything is doing well.

We have noticed the case and saw that there might be an issue with the caching of query strings on static resources. Currently we cache all kind of static resources including their query strings/parameters, cachable artifacts and do not trim or remove anything from the original resource.

It is possible that we might have accidentally mislead you about this on chat.

If you might experience any such issues as in the current case then we might be able to help you out, debug it for you or work together to find a solution.

Thanks

Hello Bruce,

the issue was fixed in FV Player Pro 7.4.16.727.

Since you are removing the query string versions, you might not get the updates file because of browser or CDN cache. Although WP Rocket does that properly – it makes the version number part of the file URL. So it should work fine.

Thanks,
Martin
