Cannot play m4a files

I installed gnome music (had installed it already but reinstalled my system) and now it cannot play m4a files. I dont know why before i reinstalled arch it had played them?
Does anyone know a package i have to install, i cannot remeber if i did so.

I'm sure you've found a solution by now, and I'm not sure if this will help?! Have you tried (with TAG editor) to change the the format from "UNKNOWN" to "Audio MPEG-4 AAC LC" ?

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 ?

Cannot play MP3 files in Dreamweaver CS4

Hi
Apogogies if this has been asked before.
I have an embedded MP3 file on one of my DWCS4 pages but when I try to play it from the Properties Inspector I get the message "Unable to find the plugin that handles this media type".
The sound file plays OK in Firefox and IE but I would like to be able to test it in DW. I have the currrent version of Apple QuickTime Pro installed.
I am using both Windows XP and Vista with the same problem.
Is there a plug I can download for DW only in order to play these files without resorting to converting the MP3 to another format.
Any help would be much appreicated.
Thanks
George

Yes but I did exactly what I accused you of doing so it was really bad!

Hi
Thank you for the apology, but as we have all (probably), misread and
therefore wrongly replied to posts, it is not really necessary.

Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file

Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file
How do I fix this?

That would probably be a question best taken up in on a site for Windows support questions. Not knowing anything about the movie you're trying to play, all I can suggest is to confirm that the format of the movie you wish to play is supported in your version of WMP. If it isn't, you'll either need to convert the movie or use some other player software.
Regards.

Windows Media Player cannot play the file because the required video codec is not installed on your computer

I can not find solution to the issue "Windows Media Player cannot play the file because the required video codec is not installed on your computer" while attempting to play the file with *.wmv extension. Some computer fail in spite of said missing codec
being present according the windrows media player in Windows 7 box

If Rashid's link does not resolve it... consider the below:
A) As of this writing, the codec for GoToMeeting webinar recordings ("G2M4" codec) was only mentioned in *one* web page, of about 10 Microsoft web pages I read, to resolve this problem (and that codec is not included, yet, in their diagnostic tool),
so if you're trying to play a GoToMeeting webinar, simply get the codec for it from their site: http://www.GoToMeeting.com/codec
B) If Windows Media Player (WMP) will not even open the file, you won't be able to get the 4-character codec's name (like "G2M4") from WMP. But VLC's media player will tell you that code, even when it fails to run the video.... and then you can
search the internet for it.
C) The problem sometimes is not actually a missing codec. Other things that have helped others, some from:
http://answers.microsoft.com/en-us/windows/forum/windows_7-pictures/the-windows-media-player-12-could-not-play-the-wma/bb823460-44df-4e8d-ba2c-42ec0e111e5a?page=3
(1) running the System File Checker (SFC.exe),
(2) opening WMP first (running both the 32-bit and 64-bit versions) then opening the file from inside them,
(3) confirming that WMP was the file association for WMV files,
(4) Control Panel -> Hardware and Sound -> Sound, selecting my audio device, and looking for a "5.1" setting (I didn't have one), to change to "stereo",
(5) checking Tools\Options\Devices\Speakers\Properties\Speaker Properties\AdvancedPlayback\ Speakers /HP\Properties\Advanced\Default Format, to select "CD or DVD Quality" (if that setting appears for your device),
Good luck,

I cannot play .mov files (from iPhone) in Premiere Elements 10.

I cannot play .mov files (from iPhone) in Premiere Elements 10. Is there a solution?
It used to work fine. I wonder if the problem has something to do with the recent iPhone update. Is there any Premiere update I can download?

Well, if it used to work... and then you updated your iphone and now it does not work... that seems to ME like the iphone update changed something in the files
But, exactly what is inside your mov files?

IOS 6.0.1 Safari won't play audio files. Error: "Cannot play audio file."

I recently updated my iPad to iOS 6.0.1, now Safari won't play audio files in any format. Error: "Cannot play audio file." Previously, it worked fine. I tried downloading and using GoogleChrome and Opera Mini, and these also won't play audio. What's up??

Solved the problem. It seems that once iOS 6.0.1 installed, it caused all of my browsers to mishandle audio files. When I reset the iPad, that cleared up the problem.
Before upgrading to iOS 6, my browsers would "autoplay" the sound files. After iOS 6, "autoplay" is disabled so you have to manually click play to play them.
Nonetheless, everything is working fine again except for "autoplay," which I can live with.

I cannot play mp3 file on itunes after i recover it from an external hdd

hey guy'z i need a little help here
i have a large mp3 file from an old 2TB which had a problem and then recovered and transfered to a new ext hdd.
now after the recovery was done and i'm trying to play my music on the itunes it wont play
any solution guys?
and another thing is the wma file why i cant i play it also on my itunes?

iTunes cannot play WMA files. Use a conversion program such as Switch or EasyWMA to convert the WMA to MP3 or AAC.
For your problem MP3, make sure it is a valid file by playing it in another player such as QuickTime. If it plays there but not in iTunes, then it needs to be cleaned up with a program such as MP3 Validator.

Leopard cannot play .avi files (MJPG format)

After installing Leopard, I cannot play .avi files (MJPG format) using Quicktime. These files work without a hitch on my other Mac that has Tiger. I've tried Perian.org, DIVX, VLN player, Windows media player, WMV player etc. Something went awry after installing Leopard.
Has anyone else experienced this problem?

Re-install the Flip4Mac QuickTime Component then open System Preferences/Flip4Mac, click the Player Tab and check the "Open AVI files" box. Restart your browser and try again.

Follow the steps to identify the video and audio
format, then look in the list for a codec.

Windows Media Player cannot play the file after ame encode with out audio?

strange behavior using media encoder today
ive selected no audio when encoding an h264 for the android...every time (5x) I tried to encode I got "Windows Media Player cannot play the file" when I selected audio the error went away..
the other issue I had was the work area only , my encodes were including the whole sequence an not the "work area only" when selected?
buggy day ..love to edit ..

The export without audio is an .m4v file, which many plays have trouble with. For now, use the audio, which creates a playable .mp4 file.

Why can't JavaFx media player play .m4a file on windows xp sp3?

Hi All
Why can't JavaFx media player play .m4a file on windows xp sp3? I got an exception that 'Decoder is not available' when I played m4a file on windows xp sp3(it didn't work on vista either), but it works fine on windows 7 , so I guess Javafx media player needs some system dependencies or resources when it plays media files, do you have any suggestions for this ?

To allow playback on Windows XP, you need to install the correct software in addition to JavaFX.
Once the system has been upgraded to meet the minimum requirements for playback of a particular type of video encoding, then playback should work fine.
See the JavaFX Media portion of the JavaFX 2.2 System Requirements:
http://docs.oracle.com/javafx/2/system_requirements_2-2/jfxpub-system_requirements_2-2.htm
Note, m4a is just a container file and data streams inside the container format need to match a supported JavaFX format for playback to work:
http://docs.oracle.com/javafx/2/api/javafx/scene/media/package-summary.html
Some approaches you could take:
- additionally encode the media in VP6 format and fallback to VP6 playback if H.264 playback fails.
- use a 3rd party player like VLC.
- don't bother supporting Windows XP video playback.
- direct a browser to a divx install page if playback fails (http://www.divx.com/).

HT203167 Moved iTunes library from one computer to another using external hard drive. Cannot play many files. Says they are missing but locates them in an archive file but still won't play them. Are the files themselves part of the .itl files?

Moved iTunes library from old computer (PC Windows 7) to new (PC Window 8) using external hard drive. Library listing shows all music but can only play a fraction of it. On the ones it cannot play it asks to locate, then refers to an archived version (an .itl file), and still cannot play them. Do I just need to copy the archived .itl over, or is that not where the actual media are (do the actual media files even exist on the new computer?)? Any advice or information on this would be helpful.

*Also...is there any way I can filter out all the tracks with the ! so I can delete the unplaying copies as they're taking up room in my iTunes? I know how to find duplicates, but then I have to go and delete each one individually...*
*Thank you!*

Since I upgraded to Mavericks I cannot play .AVI files in Aperture

Hi, I have about 1 Tera of .AVI videos as referenced files to Aperture libraries that I have spent long time organizing, tagging, and keywording... Since I upgraded to Mavericks I cannot play these videos any longer. I can play them with VLC or DivX but not within Aperture. Is there any way to ask Aperture to use VLC to play the videos? Or to get Quicktime to play them within Aperture? I assume I am not the only one with this problem but haven't found any way to solve it.
Thanks a lot for any hint!

Hi, I have about 1 Tera of .AVI videos as referenced files to Aperture libraries that I have spent long time organizing, tagging, and keywording..
It is probably not a question of avi or mov. AVI is just a container for media with a variaty of codecs. It will depend on the codecs you installed, if Aperture will be able to show these.
What is your Aperture version? Have you upgraded to Aperture 3.5.1? My Aperture version has no problems to show my AVIs. I installed Perian 1.2.3 to have more codecs.
