FLV Player works in IE, but not in Firefox

I have two copies of the same FLV player video on two different pages. Version A is here:
http://www.yoism.org/?q=node/52#jill
Version B is at the top of this page: http://www.yoism.org/?q=node/359
Versions A and B are identical except that version A has showicons set to false.
A and B play perfectly in IE.
Version A USUALLY doesn't work at all in Firefox. Version B OFTEN doesn't work in Firefox.

If I play either version in IE and then open Firefox while it is still playing in IE, version B will usually play in Firefox. If I immediately go to version A, it also usually plays in Firefox. If I open Firefox and go straight to version A, it usually doesn't play at all.

This appears to have something to do with the pages the player is embedded in, but I can't figure out what.

Notes: Sometimes, but not always, if I scroll a non-playing player so that it is an inch or more off the screen and can't be seen, it starts to play (I can hear it playing and the time and progress bar have moved when I bring it back onthe screen), but such a stuck player always stops again if brought back into view.

Sometimes when a player is only playing when it is offscreen, it will stop playing when I scroll to a completely different part of the page that displays an animated gif and will start playing again when I scroll away from the gif.

The little FLV player at the top left of every page on our site usually plays well in IE or Firefox, but usually won't play when the FLV Player problem being described here occurs..

Version B shows the central loading icon continuously active when player doesn't work.

This is Player A's implementation:

<div id="JillBT">this will be replaced by the SWF.</div>

<script type="text/javascript">
var so = new SWFObject('http://mysite.verizon.net/yoism13/mediaplayer2.swf','mpl',480,'360','8');
so.addParam('allowscriptaccess','always');
so.addParam('allowfullscreen','true');
so.addVariable('width','480');
so.addVariable('height','360');
so.addVariable('file','http://mysite.verizon.net/yoism13/JillBolteTaylor.flv');
so.addVariable('image','/images/JillBolteTaylor.JPG');
so.addVariable('backcolor','0xCCCCFF');
so.addVariable('frontcolor','0x000000');
so.addVariable('lightcolor','0xFF0000');
so.addVariable('screencolor','0x000000');
so.addVariable('showicons','false');
so.write('JillBT');
</script>

Help! Anyone know what's going on? I want to implement JW FlV Player across my website that has hundreds of videos but I am stuck and I can't proceed until this problem is resolved.

Oh yeah. I forgot to mention that mediaplayer2.swf' is the same as the latest version of mediaplayer.swf from this site. I just renamed it when I downloaded it because I wasn't sure that the other mediaplayer.swf' that someone else had put into the same location was the latest version.

I also just noticed that, when the FLV Player stops playing, the embedded YouTube videos on the page also don't work. Somehow FLV Player is crashing Firefox's ability to handle Flash.

Hello buddies,
i have a problem like this one but in another variation:
I have 2 videos on my website.

In IE: all works well

In Firefox: the second one cannot be played and the picture is not shown.
If I remove the first video in the source, the second video works good.

So is there a problem to run several videos in the same webpage ?

site is located at: http://bustos.free.fr/index.php?mode=video_guillonet

sincerely yours

Eddie from Paris :)

Another thought. At times, people have complained that my YouTube videos weren't working. But when I went to look, they worked fine. Could this have been the same problem? The interesting twist on this is that the complaint was in a comment over at YouTube which means the person wasn't able to view YouTube videos AT THE YOUTUBE SITE.

I don't know if the behavior of the failed player was the same. But if it was, could it be that there is some weird bug in Firefox that interferes with Adobe Flash (or a bug in Flash that interacts with Firefox) but only under fairly unusual conditions which this page (http://www.yoism.org/?q=node/359) seems to generate more frequently?

make sure the flash plugins in the various browsers are up to date and working: (sometimes an (un)install helps)

I actually did uninstall and reinstall flash for Firefox. The fact that other users (including Jeroen) were able to replicate this problem also suggests that the problem isn't that the plugin is not up to date.

i havent seen the error yet on my 2g win xp sp2 ff2 flash9.0.115 - but you have a lot of stuff on your page and all executed inline in the body, which is notoriusly problematic, not the least with some content management systems...

ok, you need to go about it in a systematic manner - one way, is to start a new testpage from scratch, and add elements one at the time - testing thoroughly in between to see when what breaks -
or embed using a function instead - please see the source of the examples on the [url=http://home5.inet.tele.dk/nyboe/flash/mediaplayer/]demopage[/url] like [url=http://home5.inet.tele.dk/nyboe/flash/mediaplayer/minimal_but_safe.htm]minimal but safe[/url] and [url=http://home5.inet.tele.dk/nyboe/flash/mediaplayer/mutex.htm]mutex[/url]

Hello people,

I have the same problem (no image, ethernal loading process, no play) alterning between two flash videos that are loaded into the same FLVPlayback component. I do that by dynamic changing the flv source string. If I try to load the same video twice in sequence, the second try normally works. These happens on Firefox and Safari. IE its ok!! The problem persist during a period of time... after that, all then maybe works for a while.

Additionaly, I have two other flv that can be loaded into the same FLVPlayback: the first is a audio/video flv that in the most cases (about 95%) works fine, also when the other two first commented are experiencing problems. The second is an only audio flv, that works 100%! These one, when played, normally colaborate for playing the others. After that, returning to try between the two first commented flv, the problem occurs again.

So, maybe the problem depends of the flv? Encoding process? Why the only audio flv always plays well? Why some flv increase the problem and other correct it? I also think about the download process and bandwith avaiable at the moment. Could Firefox and Safari controls the flv download in different way from IE, sometimes breaking the process?? I note that IE 7.0 is caching the video by parts - when accessing and leaving that file - and this maybe help it to play correctly.

My bigger issue is why sometime all them works fine and sometime not?

I dont have knowlege outside the Flash and cannot suppose that the problem is on the html page where the swf is embed, but its make sense.

Our site is www.rcconsultores.com.br - and unfortunatly you have to make a free subscription to view the videos... if you could do it I will apreciate.

So, lets talk about it.

Sorry about my bad english.

@Diego Spino - please make a simple testpage that shows the problem without registration!

also make sure your .flv files have [url=http://home5.inet.tele.dk/nyboe/flash/]metadata[/url] and [url=http://www.jeroenwijering.com/?search=keyframe]keyframes[/url] - and that *width* and *height* are set in the [url=http://www.jeroenwijering.com/?item=Supported_Flashvars]flashvars[/url] too
(do you see the problem if you use the .flv files from this site?)

you can check that your flash plugin is good here:

adobe flash versiontest: http://www.adobe.com/go/tn_15507
adobe flash uninstall: http://www.adobe.com/go/tn_14157
adobe flash install: http://www.adobe.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash

if the problem persists, it could be worthwhile to try other methods:
please see the source of the examples on the [url=http://home5.inet.tele.dk/nyboe/flash/mediaplayer/index.htm]demopage[/url] like [url=http://home5.inet.tele.dk/nyboe/flash/mediaplayer/minimal_but_safe.htm]minimal but safe[/url] and [url=http://home5.inet.tele.dk/nyboe/flash/mediaplayer/mutex.htm]mutex[/url]

It looks like this error is caused by an upgrade of Firefox and the flash plugin, which also causes problems with YouTube videos. See:

Hi -
I'm having a similar problem playing audio and video together. I have an FLV playing, and MP3's that play over the video. This works perfectly in IE7, but in Firefox only the FLV plays, and the audio can't be heard (although it does appear to load).
You see http://beta.overcastmedia.com/flvplayer2.php

I've tried several embed methods and just cannot get the audio to play in FF. It does play if it is not played at the same time as the FLV so I'm sure that the plugins etc are all correct.

Any suggestions?

@jonw

I assumed that the extensive discussions of the problem on the Adobe Flash Forum and Macromedia Players Flash Newsgroup (see http://forums.mozillazine.org/viewtopic.php?p=3249140#3249140 ) are an indication that Adobe knows about this. Does anyone know if this assumption is valid?

Two other things. After running the uninstaller (included in the zip file I placed here: http://www.yoism.org/?q=node/152#flash ), and installing 9.0r47 it worked fine for me,l too. For awhile, that is. Then the problem reappeared.

So the first question is whether it works for you after several days of testing and whether pages that tend to generate the problem remain working. The reason I became aware of this problem is because our page (see http://www.yoism.org/?q=node/52#jill ) seems to generate the problem with great reliability.

In retrospect, I had seen the problem many times earlier on different pages but simply exiting FF and or a computer restart seemed to resolve the problem when viewing pages that only produced the problem intermittently.

The second thing is that either solution 9r45 or 9r47 are downgrades and both solutions require telling users to down grade. So, if they are not reliable solutions and version 8 is, the version 8 solution (described here: http://www.yoism.org/?q=node/152#flash ) seems like the best temporary workaround to recommend.

Thanks kLink

In the meantime I tried to figure out myself. If I delete the "Temporary Internet Files" which are cached and then reload the page it loads the flv.

The url is www.aspee.com/aspee-products/knapsack-sprayers/arjun.asp

I also tried

<%
Response.CacheControl = "Private", "no-cache"
Response.Expires = -10000
%>

to prevent the page from caching. Still the page gets cached.

Need urgent help.

Hey guys, I had the same problem and I just figured it out. Im not sure if this will work for you but it worked for me.
After investigation I found that the player was looking for a file in my web root called crossdomain.xml. I have no idea why it needs this file but my guess is that it fails when ever it gets a 404 on a file it needs so i just created a blank file called crossdomain.xml and put it in the root of my website (example http://www.mysite.com/crossdomain.xml)

Hope this works

@Barbara12,

Your player works fine for me in IE, FF, and Opera, so you probably just need to upgrade the Adobe Flash Player for firefox and Safari.

I updated your player code:

1) you can load swfobject v2.1 directly from Google,

2) unless you need to re-instantiate the player, it's best to let swfobject manage the instantiation of the player at the appropriate time during page load,

3) a more informative alternate content message is useful when the client doesn't have the correct version of the Adobe Flash Player.

I had a similar problem with the FLVplayer component working fine in IE but not at all in FF. I finally realised that the issue was the flv path I was putting in the parameters.I was thinking old school DOS when I put them in so used "\" to denote folders which IE can parse quite happily. FF however is a bit more choosy and can only work with "/". It took me ages to realise this was the problem and I couldn't find anyone else who had encountered the same problem. So, check your slashes are pointing in the right direction.

hi all,
I had the same problem and went through a lot of exercise mentioned above until I saw my file names were lower case instead of upper case like in the root folders upload. It din't seem to matter for IE , but for FF and Chrome it does. Just make sure you have the ditto file names!
