Hello Remruata,

we are glad to hear you were able to make your video play. It is also correctly secured now.

I will ask our development team about the error.

Thanks,
Maria

thank you

Hello Remruata,

You are using URL tokens, but it seems that the video segments are loading without the URL tokens, causing the protection not to work properly.

Try using the Stream Loader feature: https://foliovision.com/2020/11/hls-download-protection-cloudfront

If the issues persist, please, send us a full report from the video checker by clicking the “Send report to Foliovision” button.

Thanks,
Maria

Yes. Thats it. Thanks. Its working now.

Another problem i had is I find it difficult trying to click the fullscreen mode icon, it goes away as soon as the cursor is going to the icon. Do i need to open another ticket for this?

Hello Remruata,

could you please send us such an video where you face this issue? Also, what device and browser are you facing the issue on?

Thanks,
Maria

and the chromecast button is not available now. it was working before.

Mária Stašová 3 years ago

Hello Remruata,

does the fullscreen button issue disappear if you switch to a standard WordPress theme? For example Twenty Twenty-Two theme.

As for the Chromecast issue, try using a basic Mp4 file and see, if Chromecast works with that.

Thanks,
Maria

Hi,
I changed to twenty twenty theme and the full screen hover issue dissapears.
Chromecast issue is also working with mp4 file. Why does it not work with hls files? I checked the “Chromecast Encrypted HLS” checkbox and it was working before. I dont remember making any changes after this.

Also How will i fix the fullscreen issue with my theme?

Hello Remruata,

I do not have Chromecast available at the moment, so I’m asking Maria to test. In the meantime please test on the first video here: https://foliovision.com/player/demos/encrypted-hls-stream

The fullscreen button might be misbehaving if your theme is using some forced CSS rules (!important). Please let us know how exactly does the button disappear. Does it change position, or does it change color? Based on that you should be able to use some CSS like this to make it appear:
```
.flowplayer .fp-fullscreen {
  color: white !important;
  opacity: 1 !important;
}
```
Thanks,
Martin

Hello Remruata,

we are having no issues with Chromecast here: https://foliovision.com/player/demos/encrypted-hls-stream

1) Settings -> FV Player Pro -> Pro Feature -> Chromecast Encrypted HLS – has to be enabled

This will lower the security of the encrypted streams a bit.

And it will set CORS headers for * origins to the FV Player Pro Stream Loader URLs like https://site.com/?stream_loader=….

Are you using anything to adjust the HTTP headers? Cloudflare might be doing that. In order for Chromecast to work with encrypted HLS streams following conditions have to be met:

Are you adjusting the CORS (or allowed domains) on your Cloudfront distribution?

2) The HLS must not be using a separate audio track. We have some plans about how to improve this to work with Chromecast. I checked your demo page and it appears to not be the case.

Thanks,
Martin

Is there anything i did wrong here?

qqqq

Remruata L. 3 years ago

I have made some changes again. Now, the chromecast button appeared on the Hls encrpyted video. But i still am unable to cast it. I tested this on an mp4 video from my s3 bucket which could be casted. I will post my cloudfront distribution screenshots and please check if i am missing anything.

Here are the screenshots of my Cloudfront distribution settings and my bucket Cors configuration as well

Hello Remruata,

thank you for the screenshots. I cannot see whether you have whitelisted the correct headers. Please check according to the screenshot I attached.

Everything else in your settings is correct.

Thanks,
Maria

Hi,
Yes, i whitelisted these three headers. If the setup is correct, then is there any other reason that may cause chromecast to not cast on this hls encrypted videos. Mp4 videos can be casted.

Hello Remruata,

here are some other things to check:

Will it play a normal non-encrypted HLS stream?

Will it play if you disable the URL tokens and the FV Player Pro “Stream Loader” settings?

Are you using any custom firewall rules in the AWS WAF?

Thanks,
Martin
