.wmv extensions

When someone sends me a movie with a .wmv extension, I get a message from Quick Time saying "error opening movie...the movie could not be opened."
The message isn't exactly helpful...What am I supposed to do about that? How do I make it run? Any suggestions?
Thanks.

Do you have the Flip4Mac QT/WMV plugin installed from Flip4Mac.com
If so, post your question on the Flip4Mac forums:

I am using Firefox 3.6.13 and have installed Windows Media Player 1.0.0.8 for Firefox. However, if I attempt to open a file with a .wmv extension it appears to function properly, except, that I cannot "play" the file. What am I doing wrong?

You probably have not seen anyone reporting the exact same problem as you. All three crash reports have the same crash signature and as currently ranked 67 it is not the commonest of reasons for a crash.
I hope you enter your email contact information when reporting crashes. I note you see this crash when using videos, others may possibly see this crash in other circumstances.
You have already tried the obvious, attempts at a fix so it is now down to wait and see, maybe developers working on the bug will report something or fix it.
Did you try my suggestion of installing portable ESR ?

How do I add the WMV extension to my Mac?

How do I add the .wmv extension to my Mac?

That does not make sense.
WMV is a proprietary video format by Microsoft. The extension is just an indication of it. You can't add extensions to computers. Extensions belong to files and indicate what format the file is in.
You can however download Apps that will let you play videos of this format on your Mac.
Any Video Player is one such option.

How do I get an attachment that has a .wmv extension to launch?

I have been sent an attachment that will not launch. It has a wmv extension and is some sort of a video file. What do I have to do to get firefox to allow this file to launch?

Usually if Firefox can't handle some media, it will allow you to open it in an external program, such as Windows Media Player.
What is Firefox doing in this case -- just ignoring your attempts to open the media?
Is this the only attachment affected, or do you have more general issues with email attachments? Yahoo and AT&T Yahoo mail users who access mail using old bookmarks have reported problems accessing attachments. Try getting to email through your Yahoo/My Yahoo or AT&T Yahoo home page in that case.
Finally, to get the Windows Media Player plugin for Firefox, if you are interested in using that, see this support article: [[Play Windows Media files in Firefox with the Windows Media plugin]].

Convert files with WMV extension to QuickTime

Is there a ways to convert video files with wmv extension to quicktime on the ipohne it self, so the video can be played on the iphone?

No. There are apps that will convert unprotected WMV files on a computer to something that the iPhone can play. Google is your friend to find video conversion software.

.wmv extensions are not working in fennec

i downloaded fennec for one reason only. to make .wmv extensions work.

Sorry, WMV (Windows Media Video) is a proprietary format controlled by Microsoft. Microsoft does not provide a Windows Media plugin for Android browsers, nor are there any third-party plugins that provide WMV support.
There is an app called RockPlayer that can play WMV files on some Android phones, but you will need to download the files to your phone first, then play them.

Why cannot I not open file with .wmv extensions?

I am not able to open file attachments that have a .wmv extension - I can open power point presentations. Am I missing an app or does Apple simply not recognize these as valid files? It seems to download, but then does not ever open.

Nevermind, got it, thanks!

Getting List of files of .wmv extension from a library \ folder in sharepoint 2013

I need to get all the files from a particular folder in sharepoint library.
I am using RESTAPI Javascript code as below :
var call = jQuery.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/GetFolderByServerRelativeUrl('" + folderName + "')/Files",
type: "GET",
dataType: "json",
headers: {
Accept: "application/json;odata=verbose"
This code retrieves all the files in a particular folder, except files with extension of .wmv.
The count of files retrieved also doesnt include .wmv files.
Can anyone tell me why this is happening.
Thanks

Hi,
As this is not an expected outcome when requesting files of a library, a suggestion is that please create a new library and upload one sample .wmv file to it and send the request
again to see if it is an issue of Document Library.
Feel free to reply with the test result if the issue still exists or there any progress.
Thanks

WMV extension where is it at?

I must be getting blind as in CS5 and CS6 I can see not extension for wmv in file type association. However it plays fine so I know it must be there somewhere. Want to open in windows media player and I prefer VLC. Can't find it to change.
Can someone tell me where it is on list?

It is not here either but then again I'm on a Mac.
And is there no option to change this behavior in Windows itself (on a Mac you have a get info command and then have the option to set the default open width also)

Hello Gene.
You need the Windows Media Player for Mac OS X.

Using .wmv clip in iMovie 6

How do I use a film clip, currently in .wmv format, in iMovie HD 6? I am using iMovie for the first time, and when importing a new clip with a .wmv extension, the clip has text across the middle of the screen 'Created with Flip4Mac Trial' 'www.Flip4Mac.com'.
I did have Flip4Mac, but have deleted it completely from the MacBook.

Sounds like you, at one time, converted a wmv to a .mov, cause wmv will not import into iMovie without converting it first. The watermark on it says that you didn't have a paid version. The free version allows you to convert up to 30 seconds of a clip, but lets you know that it's in trial mode with that watermark.
If you indeed want to use wmv stuff in your edit, then you'll have to buy F4M or there's another thing called Visual Hub...F4M is the better of the 2, but VH is about twenty bucks cheaper.

Quicktime no longer playing .wmv

Email attachments with a .wmv extension used to play just fine and recently they stopped.
I can save the attachment to the Windows disk in Boot Camp and they will open OK next time I switch out Mac OSX.
What happened? How can this be fixed so the video plays in the Mac side?

Flip4Mac is a playback component for viewing WMV in Quicktime. You have to download the component: http://dynamic.telestream.net/downloads/download-flip4macwmv.htm

Can't open .wmv file

Trying to open/play .wmv files; I have the latest version of flip4mac installed and appears to otherwise be working fine. These files do have the .wmv extension, however when I click on them to play/open I get the following message "the movie/file could not be opened. The movie/file is not in a format that QuickTime Play understands".
thx
Mike

I'm able to open on PC at work, so I don't think that would happen if files were corrupt. How can you tell what codec version they were encrypted with? I checked in "get info" to verify file ext type and they are .wmv.
