Only black box on newest Firefox and Adobe Flash

Here is a test link:

it does not work on Firefox 7.0.1 with Adobe Flash 11.0.1.152. Only a black box appears.

It aslo doesn't work when using FF 8, 9, 10 in addition it doesn't work with Chrome YET it works in Opera and Safari.

This leads me to think that the cause may simply be an incorrect video version.

Why?

The doctype that you have declared is for html5. Therefore FF and Chrome thinking that it is in html5 I must use the video format being support in html5.

To confirm this try using the ogv video format which is support by FF and Chrome in html5.

That said, in order to satisfy the browsers that support html5 you would need to also include the video formats of mp4 iso v2.

I would recommend using mp4 and ogv and thereby covering all of the bases. These are the two video format that I usew on my web site exclusively, www.mirana.net

Hi Willie,

Thanks for your reply and greetings from Zurich :)

Hmm. I'm newbe to video streaming and I didn't set any format on purpose. What appears strange is that it DID work before I updated to Flash 11. Is worked perfect on Flash 10.

Anyhow, I will investigate but would very much like to hear additional feedback from the JW guys, after all I paid for the component and haven't received any reaction yet.

Thanks again Willie!

Best,
Marc

@Marc

I did notice a change in the security settings for flash 11.

Well I am trying to earn my "Grasshoper" badge and awaiting such from Master Ethan.

I do like Zurich BUT prefer Genevé BUT best of all Lugano

ciao

@Marc -

I can't replicate your issue myself - I'm also using Firefox 7.0.1 and Flash 11.0.1.152.

The one thing you can try is turning off hardware acceleration in Flash. This setting has been known to be problematic depending on what video drivers you're using.

@Pablo,

Thank you for your reply. I have turned off the hardware acceleration setting, but in vain. Its still a black box and nothing more.

It was one of our employees that first noted that its no longer running. We currently have two machines, both with firefox 7.0.1 and Flash 11.0.1.152 where its not working. hmmm... we also both have Win 7, myself with 64bit. Don't know whether he is using 32bit or 64bit.

Does that help?

One last thing: If i use a free player (that I don't like too much) all is fine: check here: http://www.wieland-oertli.ch/walther-trowal-gleitschleiftechnik/strahlanlagen/

Thanks,

@ Pablo

There seem to be a lot of people having this issue and is does not seem to be directly JW player related. See this comment:

"I'm using Firefox 7.0.1 on a Windows 7 system with the latest Flash plugin, currently 11.0.1.152. I am attempting to use slideshows created with Visual Slideshow 1.6. They work using other browsers such as Internet Explorer, but not with Firefox. I hope this bug can be fixed soon. Thanks."

@Marc -

Very strange. I'm on OS X, but I just tested on a 64-bit Windows 7 system (Firefox 8, which just came out today, and Flash 11.0.1.152). I'm going to have to chalk this up to a generic Flash/Firefox problem until we have a better idea of what's going on.

I am also not having any issues with win7-64 bit
using FF8, 9a2, 10a2(64-bit) and 11a1 with flash 11.0.152 32 & 64 bit
IE9 doctype IE9 or IE8
IE8 standard mode (32 & 64 bit)

It would be worth knowing more about the system that this was indicated
chances are that there is an issue at the user's end.

Perhaps IF I may suggest that "crap cleaner" OR CCleaner to be used and an overall defragmentation of the system that was used.
Are all updates for that system up-to-date?

Gerne kannst du mir bei email kontactieren

Hi Guys,

Thanks for your support. Strange, that you cannot replicate that on a Win7 64 maschine. My employee is using the same system that I have. I am pretty sure my maschine is 'clean' as its pretty new and I usually know what I'm doing (not messing around with installs).

This guy here has the same problem:

https://support.mozilla.com/ro/questions/884902

I also deinstalled flash player plugin for firefox and re-installed it, but in vain. And it DID work on the 10.x version of the flash player plugin, it ceased to work when going to 11.

Anyhow, I am lost and can't do much about it. Probably its now JW Player related anyway, so I will just sit it out :)

Thanks again guys!

Just updated to Firefox 8, but still not working.

*sigh*

it must be an upgrade/update issue....

I just deinstalled firefox 8, deinstalled the adobe flash plugins... then downloaded and installed firefox 8... tried to click on a video and was asked to download adobe flash 11.0.1.152 which i did... and now its working :)

i checked the plugins section and it 'looks' to be exactly the same setup I used to have....

apparently, this issue is caused when updating, instead of clean installing, firefox and the adobe flash plugin.

Hope our clients realize that too :)

thanks guys, very much appreciated!!

@Marc -

Glad you found a reliable workaround. Thanks for posting your update!

Just a side note for these problems, that sometimes also Adobe AIR creates problems with Flash. In these situations I've found that usually the best practise is to uninstall AIR and FLASH and then first install only the Flash and after checking for problems again trying to install AIR again too.

jw-player not working firefox

@sunil - Please post a link where you can see that the JW Player is not working in Firefox.

Hi!

We are having the same problem with newer browsers (chrome, firefox), i think it's related to Flash 11. On our website www.studentkatalogen.no some playlists(only the ones with images? not sure about this..) show a black screen in browsers running Flash 11. The same url's are working in browsers with Flash 10 (older versions of firefox etc).

Example url: http://studentkatalogen.no/bergen/kunstmuseene_i_bergen
( http://studentkatalogen.no/images/player/playlist/135 )

If i add flv-files instead of the jpg's in the playlist it's working fine except for the autostart-feature. I need to press pause, then play again before it starts playing.

@Eivind -

The problem here is due to a rather obscure Flash limitation. Your images are being served from a different domain than your HTML page (http://old.studentkatalogen.no vs http://studentkatalogen.no), which triggers a call to http://old.studentkatalogen.no/crossdomain.xml. This file must return a crossdomain.xml file, but instead it returns a 302 redirect to a different location.

You can fix this in 2 ways: 1) host the images on the same server as the HTML page, or 2) make sure there's a valid crossdomain.xml file hosted at http://old.studentkatalogen.no/crossdomain.xml

Ahh.. really! And that limitation is introduced in the latest flash-version? Video inclusion from other pages work, but images don't..?

I'll try adding crossdomain.xml then..

Thank you PabloS!

@Eivind -

No, it's not a new limitation, but it's possible that the integration between Flash and Firefox has changed the way this is handled.

Video files don't need the crossdomain.xml. The only reason the images do is that the player performs a smoothing on the image to make it look better when scaled. This operation triggers the crossdomain.xml load (for reasons which you're probably not interested in).

im in same boat .. not work in ff and chrome .. with flash 11
the video is from youtube

( work fine with old flash and ie )

I can see the videos on your site just fine, using Chome and Flash 11:
