can some help a novice
I am using Win media 9 and keep gettin WMV1 and 3 codec error
Where di I get the codecs??? reply

Try the microsoft website...update windows and media player(if available). i don’t quite understand why this problem is happening...wmv is windows media video...one would think that something should be able to play media that was designed for it. reply


necesito el codec wmv1 gracias reply


i tried downloading from microsoft but microsoft says no such file could be found. please help reply


This is my problem, when the error is shown after I try and play the wmv file media player automatically gives you the choice to search Microsoft for the file but it comes up with nothing to download

the error that comes up is as follows
The WMV1 codec is required to play this file. To determineif this codec is available to download from the web, click web help.

Web help button then takes you to http://www.microsoft.com/windows/windowsmedia/support/missingplugin.asp?codec=WMV1

which bring the message Windows Media Player cannot play the file because the required codec cannot be found. To determine how to obtain the codec identified as WMV1, contact the provider.

Does not happen to all WMV file on this computer either just a few here and there. Seeing that I have had no-one even tell me they are having the same problem I am even more confused.

Hey Sean,

I am having the same problem. The weird thing is it just started happening after I downloaded an .avi codec pack.

For example, I had a certain file that played fine and then I downloaded some codec stuff (for other files) and now those original files keep giving me that “wmv1 codec error'. Its weird and frustrating let me know if you figure it out and I will do the same. Good luck.



Yes. I have been having that same problem. I downloaded every codec I could find, reistalled all my WMV related programs, and still nothing. If you guys find anything out about this, please share :_: reply


I had this same problem. I solved it by installing Windows Media Encoder 7.1.

However, some time later, the problem returned. I uninstalled it and reinstalled it, and it fixed it again.

I’m not sure what all had been installed in between, but I’m keeping a log now.

You can find the encoder from Microsoft at


Hope this works for you. reply

I have risolved this common problem ;) reply


Thanks panasync,

I to got the same error for a game, here is the link to the file to solve this problem, it also contains many other codecs for WMP. Hope this helps you.


Download the file: FFmpeg version 0.4.8

Easy reply


Yeah FFMPEG doesn’t use external codecs. It’s a filter based system and is stand-alone.

Effectively you can uninstall codecs and just use the filter to watch movies. The stability of a movie’s playback will all be down to the ability of the filter.

VideoLAN and MPlayer are both media players based on the FFMPEG project:

Always use mplayer2.exe . I suffer the codec error and i tried this other program ( still in windows ) and problem resolved. reply


Try installing Windows Media Encoder 9 Series. It worked for me and I was having the same problem. reply
