Can't play m4v videos in Firefox.
Hello. I was hoping that someone could help me with a problem. I have a html presentation for a class that I teach. (I have created the presentation.) It includes m4v videos and I can not play in Firefox. He said: "no video with format supported and MIME the type found. I can play the videos if I open them outside, but I need to work in the presentation. Help, please. Thank you.
Firefox can not read files with the file extension .m4v via audio or video tag that those are not supported file extensions. You can only read these files via the object tag to use a plugin that supports this file Firefox extension. You can force it to use a specific plugin by specifying a type (type = "application/x-mplayer2").
<object data="file://<path to file>" type="<to force a specific plugin>"></object>

I can't play the videos that play in wmv, I get the error message 80040154. This is the codec that is false and if this what you do need me and how to get it and load it?
Hello
· Were you able to play WMV files earlier, if yes, then you remember recent changes to the computer?
· What is the accurate and complete error message?
· Are you able to play other files?
I suggest you to rebuild the Windows media player library and check if the problem follow these steps:
a. exit Windows Media Player.
b. click Start, click Run, type %LOCALAPPDATA%\Microsoft\Media Playerand then click OK.
c. Select all files in the folder and then click on Delete on the file menu.
Note: you don't have to remove the folders that are in this folder.
d. restart Windows Media Player.
Note: Windows Media Player automatically rebuilds the database.

Firefox can't play youtube videos (only from youtube, other video sites work well)
Since about a week ago firefox in my laptop can not read the youtube videos (only from youtube, videos from other sites and flash games work well), both on the site or embedded on another site. This shows only "an error has occurred. "Please try again later".
I use firefox 13.0.1 and the latest version of the flash plugin.
My laptop is i5 with win7 64 bit and it has clean, no viruses or malware.I tried all the solution posted here, but nothing works.
I tried to uninstall - reinstall both firefox and flash, disabled add-ons, safemode, downgrade from earlier, flash, uninstall realplayer, changed the dns, reconfigured my modem, my curse what ISP (perhaps connection related?), still unable to play videos from youtube.I tried to use different computer, I used my old pc winxp with the old version of firefox (with the same configuration as the firefox I use in my laptop) and my ipad, they can play videos, but playback is stuttering which never happened before.
Curiously, I've tried chrome (on the same laptop) and it works well, no stutters.
This problem has something to do with the firefox updates, updates, flash, both, or something else?Please help me, I don't want to go back and forth between browsers just to see the video on youtube and I really want to change browser.
Thank you!It's very strange... it will also be a very long shot, but it is possible that due to the long url (& feature = relmfu) it worked. I highly doubt this is the case.
I recommend not to clear your cookies, either of them or one of them to youtube.
And you've probably already tried this, but playing the video on the various quality parameters may do something.
And finally, have you tried to contact youtube/google on this subject, or restart your pc after making sure that all your stuff is up-to-date? (you have probably both)

Cannot play flash videos in Firefox
I am unable to play content flash facebook or CNN video. I use Firefox 31 and Flash 14.0.0.179 (32-bit) running Windows 7 Pro. I also have the 64-bit version installed for use with internet explore. These videos play fine in internet explorer but not in Firefox. Videos CNN stopped play in Firefox months ago and Facebook stopped in recent days.
I started Firefox in safe mode, reset Firefox, uninstalled and reinstalled flash and uninstalled and reinstalled the latest version of realplayer (found this suggestion online). So far, nothing worked.
Just CNN videos freeze once the Player control bar appears at the bottom of the frame. Advertising plays, but it hangs at the start of the video of actual news.
Facebook displays the thumbnail for the video (no AutoPlay as it does in IE will) and when you click it you get the pop-up window with the user comments for the right, but just a black square where has to play the video.
If I right click and go to settings for flash, when I click on disable hardware acceleration, it reactivates it as soon as I click on close on the setting screen. When I return to the parameters of the box is checked again.
Accidents or other problems with some multimedia content in Firefox (for example, videos from Youtube and Flash animations or games) can often be solved by doing as in these Knowledge Base articles:
On Windows Vista and above all, you can disable protected Flash mode by following the instructions on these pages:
- http://forums.Adobe.com/thread/1018071#TemporaryWorkaround
- http://KB.mozillazine.org/Flash#Disabling_Protected_Mode_in_Flash_11.3
(See this blog post Adobe for more technical details on protected mode Flash.)
Please tell us if it helped!

Can't watch youtube videos in firefox browser
When I try to watch any youtube video in Firefox, I get a black square where the video is meant to be. I tried solutions in the areas of appropriate assistance without success that I can not find the firefox tool button to activate javascript. I also have the latest version of the shockwave player. How can I go about fixing this problem?
It is a problem caused by an add-on/extension installed. Recently, I helped another person to solve the same problem.
Launch FireFox in Mode safe mode, which disables all add-on/extensions & trying to watch the same videos again. Then select just each module individually again until the problem resurfaced surface to identify the add-on causing the problem.
