JWPlyer 6 is not loading video in FF (latest version)

Hi Team,

We are using JWPlayer 6.8 and we are facing an error with loading of the video in player with Firefox browser version (40.0.2) . This is a random issue when we play video sometimes it works fine but after reloading the page, JWPlayer becomes unresponsive .

You can test the same with the following link and find the attached video of the same issue which we are currently facing.

Video sample: http://simiancheese.com/ff_YT_issue.mov.zip

Kindly suggest how should we resolve this issue apart from updating the JWPlayer to latest version.

Please let me know if I can provide more information.

Regards,
Sanjay

Hi,

We have the same issue, using JW Player 6.12, tested on Firefox 37, 38, 39 and 40 on WIndows 7, and FF 40 on Mac OS X Yosemite.

I can play any video on a site once, and then all subsequent attempts to play other videos (or the same one after a page refresh) trigger an error, "Error loading media : File not found".

You can see it here : http://voir.ca/video/musique/2015/08/10/voirosheaga-2015-les-artistes-internationaux/

The only way we found to work around this error is to delete site preferences every time (FF Options -> Privacy -> Clear recent history -> Details -> check Site Preferences).

Any help would be appreciated.

Thank you.

To me in Firefox 40 youtube videos not working. If it works for one video, the others are not working. This happens with JWP 6.12.4956 and Firefox 40. It does not happen in IE 11.

Nota Bene: all videos are in the same page...

Hello,

I have tried your stream as well as others in FF 40.0.2 in OSX and have not had a problem playing back after a refresh of the webpage. I am also checking the console window to see if I can uncover any anomalies and see nothing. Do you guys happen to have a screenshot of your console window or any other errors displaying besides the: “Error loading media : File not found”?

Thank you,

Hi Randy,

We have seen a few times this message in the console window "Could not add internal listener", but it happens only once in while, not consistent with the inability to play a video. (see screenshot here : http://s8.postimg.org/wl9p1tsv9/jwplayer_error.jpg)

Our videos are played from Vimeo (and the two others here are from Youtube), maybe that can help narrow down the problem.

Thanks.

Hi Randy,

No, there is no error in console as well as in network tab. I have shared the full video for your reference and provided the URL so that you can take look.

Video - http://simiancheese.com/ff_YT_issue.mov.zip
screenshot - https://www.dropbox.com/s/rdwns1yqy9ind59/JWplyer_unresponsive.png?dl=0

This is a random issue, refreshing the page either make the video work properly or make the player unresponsive.

Please let us know if there is any specific step should we follow to debug the issue?

Thanks

Into my web page there is no error but randomly players stop playing youtube video without reason.

http://www.alecos.it/diary_15092014.php#P163263

Try all videos, may be an incompatibility issue between firefox and latest flash player on windows 8? but since the player works on IE 11 on same machine I must think that there are some incompatibilities in JWPlayer with firefox.

Let's me know something...

Thanks

Guys

Since Firefox initially blocked Flash in the browser there have been numerous issues with JW Player working in Firefox when rendered in Flash mode.

By all accounts, this is likely to get worse:

http://www.jwplayer.com/blog/chrome-power-saving/

I would highly recommend that you render your players in HTML5 mode if at all possible.

@alecosnet - since you are only using YouTube media and JW6.12, there should be no problems switching "primary" to "html5" for a much better experience. I've tested this on your site - seems to work fine.

@webmestre - since you are using Vimeo MP4s, I would suggest you too default to "primary":"html5" - as not only are you faced with the Firefox/Flash issue, but also the fact Vimeo URLs will redirect to HTTPS protocol. This causes other cross-protocol issues when using the Flash player - particularly when your parent page is accessed using HTTP.

@skumar12 - again you are using YouTube, but you are on JW6.8. Unfortunately decent HTML5 support for YouTube wasn't introduced to JW Player until JW6.9+ - prior to that it would always render in Flash mode. I know you've discounted upgrading to the "latest version", but by this do you mean JW7? Can you at least update to the latest JW6? You could do this by loading the library from here: http://p.jwpcdn.com/6/12/jwplayer.js

James Herrieven, thanks! I changed from primary: 'flash' to primary: 'html5' and now seems to be working fine. Thanks for sharing this fix...

As you can see my site now is working as expected:

Thank you so much James Herrieven!!!

We updated the JWPlayer to 6.12 version and videos are working as expected. As per my testing till now, everything seems working fine but I am looking for the specific changes which you have introduced in JW 6.12, so that we can avoid the regression in the videos?

We are using JW Player Version 6.12 and we are having the same problem with Firefox version 40.0.2.

A spinning wheel will come up and the video will not play.

Sometimes the video will play once but after a few plays it will stop working.

We are using “flash” as our primary in the code. If we switch this to “html5” in the code it will work with Firefox 40.0.2, BUT we will render useless the player for many versions of Internet Explorer.

As bad as we would like upgrading to version 7.0.1 of the player, at the present time is not an option either, as JW 7.0.1 does not support IE 7 and 8 ( we have large number of users on this format, too large to ignore at this point).

Do yourself a favor, If you have Google analytics on your site, go to "Audience" > "Technology" > "Browser & OS" and click on the browser to see what browser versions is your audience using the most before you make modifications to your player.

Is there a patch, a work around or a code trick that can be use for JW Player Version 6.12 to fix the Firefox issue on version 40.0.2?

Any help or feedback will be great. Thanks

You can't "fix" the Firefox/Flash issue, but you can work around the problem by rendering in HTML5 mode specifically for Firefox - or more sensibly, by rendering JW Player in Flash mode only for IE7/IE8:

jwplayer(...).setup({
...
"primary": (jwplayer.utils.isIE(7)||jwplayer.utils.isIE(8)?"flash":"html5"),
...
});

Hi James,
We tried your solution and it worked. The problem is that now it will load things like playlist from the channel you are embedding, from "Next Video" Overlay comments "subscribe" and so on. where before it would filter all that. Basically it looses the point of having a JW player as it's now a Youtube player. Any thoughts or suggestions? Thanks

Jose
