Emfield plus Firefox doesn't always display the flash video as intended. I have an example for you to try out, test it out in Firefox and non Firefox browsers. I can't yet determine if it is a browser issue, an emfield issue, or a theme issue. Working on:

I can't seem to replicate the problem, though what exactly is it supposed to be doing that it isn't?
I tested FF, IE7, and Safari, all on my WinXP laptop and I can't see any real differences.

Yeah, sorry about that. I could have given a better description.

What I was seeing in Firefox was a blank area in the node that should have contained the embedded video. When I clicked in this blank area, I would hear audio from the video playback, but no image.

I'm using Mac versions of Firefox and Safari.

Funny thing is, it fixed itself and I can't reproduce it atm. Could have been a problem with the video file itself and not one of the modules or themes. I'll keep looking and if it comes up again I'll repost. What should I look for if this error comes up again?

It sounds like either a problem with the video, the browser, or the flash player. At any rate, I'll leave this open for now, let me know if you run into any more problems.

I'm having this exact same problem.

Can hear the audio, but see no video. I tried both blip and YouTube embeds.

This is true for Camino and Firefox on a Mac running 10.5. It works fine in Safari 3.

I should add one more thing. This is against the latest dev version.

On an older site I see I have the 6/26/07 dev version of emfield and that works fine on Firefox and Camino.

Alex U-A helped me out via IM. This is a problem with Firefox MAC having trouble with css opacity settings. Notably, in my case at least, the admin_menu module uses the precise opacity css that Firefox on the mac hates. Since end users on my site don't see admin menus there won't be a problem on those sites.

For seaneffel, he likely had the experience that I had that it suddenly solved itself when logging out or switching roles, something that would turn admin_menu off.

I've been having this same problem. I tried emfield 1.0, 1.2 and the current dev. Lo an behold, it started happening when I installed administration menu. I've removed it and now the videos display again. Yay!

Not sure whether to post as an issue for administration menu module.

Yeah, it would be good to let the admin menu people know about this issue.

I'm going to close this, as it's an admin_menu problem (one that's been around for a while, but the issue doesn't belong here)

Even though this is an admin_menu issue as Alex mentions, it's likely that folks may continue to land on this issue here and I thought I'd give a bit more precise info about how to fix this in admin menu.

On line 26 of the latest version of admin_menu.css (which is 2.5 -- though this file hasn't changed much over upgrades, so you should have trouble finding it) you'll find:

#admin-menu li li { width: 160px; background: #202020; filter:Alpha(opacity=88); opacity: 0.88; }

Change that to:

#admin-menu li li { width: 160px; background: #202020; filter:Alpha(opacity=100); opacity: 1.00; }

I actually think the admin menus look better at full opacity in addition to fixing the video problem.

As a best-practice it is advisable to make the above change in a css override file or in your theme's style.css file, depending on your theme's strategy for overrides -- as opposed to making the change in admin_menu.css. That way it is possible/likely your override will continue to work after each upgrade of admin_menu with no further fussing. If you make the fix at admin_menu.css you'll overwrite your correction when you update the module.
