.mp4 video's audio won't play on Firefox, even with Microsoft Windows Media Player Firefox Plugin 1.0.0.8

Title says it all: trying to play any .mp4 video files, or anything that utilizes .mp4 files period, will have the video play just fine, but with absolutely no audio at all. I run a Windows 7 Home Premium, and have tested several sites that utilize .mp4 video files, and have tested it on Internet Explorer, with Explorer showing better results at playing both the audio and video.
I have checked to see if media.windows-media-foundation.enabled is true in the about:config menu, and restarted Firefox, but to no avail. Any ideas as to what could be the root of this problem?

Hi Soundless_Cyborg,
Can you please specify an example url where this is happening, sometimes the video player does not support the codec.
Maybe you need to set it as default for this file type:
Open Control Panel > Programs > Default Programs > Set your default programs > Select Windows Media Player from the lists under Programs > Set this program as default > OK

Playing music through Air Tunes using Windows Media Player

Hello to all.
I am planning on buying the Air Port Express so I can play music wirelessly from my Dell. The only problem I have with is that I can't use the keyboard media buttons (play/pause, stop, next, previous) with iTunes. These buttons work with Windows Media Player, so I was hoping that I could use WMP instead of iTunes. Can this work? Or, is there a way to make the buttons work with iTunes?
Thanks a ton.

Don't know about doing this in windows, but on a Mac you can re-map the keys for those commands to different keys on the keyboard. Or perhaps it would be better to say that you can map ADDITIONAL keys to those commands. There should be something to allow you to do the same thing in Windows.
Good luck!

Playing back Recorded TV Programs using Windows Media Player and only hearing Sound from Front Speakers

Hi All,
I have Windows 7 Ultimate 64-Bit Service Pack 1 with Windows Media Player 11 installed.
When I click on one of my Recorded TV Programs to watch and hear, I can only hear the Sound coming from the Front Speakers.
When I right-click on the Program and open it up in Real Player Cloud. I can indeed watch the program and hear Clear Sound coming from all 5 Speakers plus the Subwoofer.
What setting do I change to use Windows Media Player and have sound coming from all 5 Speakers and the Subwoofer?
Thank you!

Hi Andreas,
Thanks for the reply.
The link you put up, takes me to the page, but
"The requested URL /surround/www_lynnemusic_com_surround_test.wma was not found on this server."
That was WaterFox.
The webpage cannot be found
This in Internet Explorer 11.0
The Files in question were Recorded by Beyond TV to my Local Hard Drive.
When I open the recording in Real Player Cloud, installed on my computer, not streaming over the Internet, I hear it correctly played.
When I use Windows Media Player, nothing can be heard from the Rear Speakers.
Speakers and Hardware are working fine.

Video and audio won't play in Itunes...just a gray screen

i put my digital copy of the hangover on itunes but it won't play. it says it is playing but it's a gray screen and no audio. whats wrong??? it plays on my ipod touch fine though.

There is an issue with the latest iTunes version that is causing downloaded movies/songs from not playing on your computer, but should work on your iPod. Until Apple releases an update that'll fix this, this problem will probably not go away.

Quicktime audio won't play in Firefox

Hi, my name is Ryan Janus. I'm designing a web site, and I'm trying to embed video and audio using Quicktime and the <embed> tag. Video: no problem in any browser, including Firefox. Audio: no problem in IE or Opera, but for some reason Firefox is misbehaving. It's giving me the Quicktime question mark. This happens on PC's - I haven't tried to see if audio works on my Mac at home. It doesn't matter, though - I'm not posting something that will alienate a sizeable portion of PC users. Any ideas why this is happening?
Thanks,

.mp4 video imports but won't play/edit?

I'm trying to edit some .mp4 clips in my iMovie 11 and am having problems. They import fine, but when i try to edit them, play them, etc all I get is the audio but only the first frame of video. There's also a small yellow circle in the bottom left corner of the clip in the viewer.
Can anyone help? I'd like to edit and have playback.
I usually use GoPro helmet cameras but this video is from a more fancy HD camera.
thanks

Does the small yellow circle have a number within it? The yellow symbol (with number) usually indicates that the clip's frame rate differs from the frame rate you've set for the Event or Project, normally either 30fps (NTSC) or 25fps (PAL).
You may have to import the clips again choosing a frame rate that matches your camera. If you can't select a matching frame rate, another option is to convert the mp4 files to another format. The free app MPEG Streamclip should be able to do this. Preferably, convert to Apple Intermediate Codec (AIC), otherwise H.264 format.
You can download MPEG Streamclip from the developer (Squared 5) here:

FLV video in PDF won't play for Mac user with Reader 9.4.5.

I recently created a PDF with an embedded FLV file. I'm using Acrobat X Pro, so embedding the file created a Rich Media Annotation (RMA). From what I've read, anyone using Acrobat or Reader version 9 or later should be able to play the file. However, one of my readers on a Mac can't play the file, and in fact, doesn't even see a preview of it on the page. He just sees a blank spot.
Can someone shed some light on this?
Thanks.
Dave

There are hundreds of PDF readers. Most of them only view only simple files and fail with interactivity, or PDFs for specialized uses like prepress. As Bob said, the only readers you can be sure of are Adobe Reader and Acrobat. Tell your viewers to download the FREE Adobe Reader to get the best viewing experience, and provide a link to Adobe Reader.

Videos on Youtube won't play on Firefox

When attempting to watch videos on Youtube, I'm presented only a black screen where the video should be, and no means of "liking" "disliking" or commenting on the video below it. I can navigate Youtube just fine, and it works with other browsers. I've also found that changing the address start to https:// allows me to watch videos, but makes navigation of the site very difficult. Hulu and Netflix work just fine on Firefox, it seems to only be Youtube that isn't working.

Try clearing the Cache in Firefox.
Tools-> Clear Recent History -> [v] Cache
or
Tools->Options->Advanced->Network -> Offline storage -> [Clear Now]
Youtube may have made some changes recently. Clear the Youtube cookie and refresh page if above does not do it.

Trouble playing downloaded audiobooks with Window Media Player

I can’t get audible book downloads from Net Library to play on my computer. Microsoft Windows Media player v9 and above is required to listen to eAudiobooks. I have this version. When I try to launch a download I get the message: cannot open file; verify file and path are correct. What do I need to do?

Hi, kathy. Welcome to the Discussions.
The Net Library audio books you are downloading are undoubtedly using a version of WMA-DRM (Windows Media Audio - Digital Rights Management) later than version 1.3. According to this post on another forum and related info on Microsoft's Web site here, version 1.3 is the latest version of WMA-DRM supported by WMP9 for Mac OS X.
In other words, the audio books use a later version of DRM (specifically the Microsoft Windows Media Rights Manager ) than that supported by WMP9. They simply will not play in WMP9.
Flip4Mac will not help you here:
• It clearly states on this page that "Note: Flip4Mac does not support content that is protected with Windows Media digital rights management (DRM). "• Flip4Mac would not let you convert the WMA-DRM-protected files to QuickTime files as this would require cracking the DRM protection, a violation of the U.S. DMCA (Digital Millennium Copyright Act).
Accordingly, you're out of luck with the Net Library audio books that do not play in WMP9 unless you have a PC running Windows and WMP10.
That Net Library went with files protected by WMA-DRM is a sore point for many Mac users. Search for Net Library in this page for some examples of similarly frustrated users.
Good luck!

Windows Media Player no sound while playing a avi file in server and client connection using TCP/IP connection

Hello there
I have a problem with my windows media player while using server and client connection by using TCP/IP connection. So when I play a video using Windows Media Player in LabVIew there isn't any sound come out but when I'm playing a video by a Windows Media Player only the sound will come out. Can you help me solve this problem?
I also upload the vi as the reference.
The username for the client is ihsanhaikalz and the password is ganteng
Thanks

Hi ican,
I was looking at your VI's but I cannot seem to pinpoint exactly where you are using Windows Media Player. In order to more quickly assist you, could you please recreate this issue more concisely in a smaller set of VIs. Also, were you able to get sound when you did not use the TCP/IP connection and simply played the files in LabVIEW?
I noticed in a few places that you were using the Play Sound File.VI from the Graphics and Sounds palette. Is that what you are refering to? I noticed there that the file path that you have designated for the song is simply the song title. Instead, this should be a path to where the song is located on your computer.
Also, if you are planning on using Windows Media Player, have you considered using the ActiveX commands for Windows Media Player? Here are a few examples if you are unfamiliar with this functionality.
Example 1 and Example 2.
I hope this helps!

Audio has ceased when at Amazon and with e-mails with audio attachments. This only during last few days previously O.K. Windows Media Player still working so no problem with speakers only happens with online audio. John

Operating system Windows 7. A few days ago no problems with audio, clear sound when listening to e-mail audio attachments and Amazon music samplers. During last 2/3 days both attachments and samplers fail to work, but when playing music from library held in Windows Media Player no problems. This would appear to show no problem with speakers etc and I have not knowingly amended any audio controls.

Thank you so much for replying.
Yes I have removed and reinstalled WMP.
I had good results with the PD6 application installed on the default path onto the C: drive with the one exception that if the application was launched by accident and the user data path was not available, the PD6 application would blow away my custom user path registry settings. Now that I know what they are I have made a .reg file to repair my registry to my desired user data paths.
Installing the application on the removable drive appeared to help prevent me from launching the application by accident and overwriting my registry with default user paths.
So which is the less of the two evils?
If the application directory is not available, windows media player still tries to launch the .msi for installing PD6.
If I install the application to the C: drive but the user data to the removable drive, launching the PD6 application without the user data drive will still corrupt my registry settings for a user data path.
Both these issues seem like a logical (if not easy) fix that should be done in the PD6 application and installation package. I mean really, cannot anyone tell me why windows media player is checking the PD6 application directory? Why in PD4 did we have an option control for setting the user data path from the PD4 application? Why is this option not in the PD6 application, just the installer?
I am given a choice during installation to move the user data to another non default location. Why else would this be provided if not to accommodate my kind of request to store the user data into an alternate location other than “My Document”. Certainly Palm is not trying to force the users on how to protect and store their personal data?

Streaming Video for Windows Media Player?

I have a website with steaming video that only opens in quicktime and I need the video to also open in Windows Media Player for people who only have access to a PC and do not want to deal with Quicktime downloads. Does anyone know how to do this on a MAC? I use FCP 5, Compressor, ect.

You are going to need to have two versions of the video file. One for Mac Quicktime users and one for WIndows Media Player users.
WMV Studio Pro looks like it could meet your needs.

However you will need a Windows Media Server to stream the WMV file otherwise it will act as a download only.

Advice on how to make Windows Media Player play DVD's not the Tosh player

I do not want to use the pre-installed Toshiba Media Player to play DVD's, I want to use the installed Windows Media Player. I cannot change the default DVD player to WMP in Control Panel as the only options are either Toshiba's or Nero's player.
WMP can play CD's, MP3's etc but cannot even read any DVD in the drive. Anyone got any advice on how to do change this?
It;s a Toshiba Satellite Pro C850 with Windows 8 installed

The free KLite Codec pack which equips the OS including Media Player for DVD decoding, thus all your currently and even most future installed players. http://codecguide.com/
It comes in varying sizes but even the smallest version enables WMP for DVD's
After installing KLite, you right click the DVD drive within Windows and select the "Open With" or "Play Disc" menu option and select Windows Media Player.
You can also just use the Windows Run Box / Search box and enter
dvdplay
which activates windows Media Player DVD menus.
Microsoft hasn't always included DVD playback in Windows and then started offered it as a fee based upgrade for XP and Vista, before finally including DVD playback in Windows 7 in what some Microsoft insiders said was an apology for Vista before removing it again in Windows 8.

Premiere Elements 4 audio won't play on mp4 files, codecs missing/unavailable on .mov files

I dowlnloaded Premiere Elements 4, and when I import mp4 files, the video plays but the audio will not. I've also tried to import .mov files, and an error message pops up that says "Codec missing or unavailable." I downloaded the latest version of Quicktime, but that didn't change anything. The files will play back on the video camera, but I"m having trouble with them on my computer. The audio on the mp4 files plays in Quicktime, but not the video, and vice versa when I import them into Elements. Any suggestions?

Does Quicktime Pro also edit .mov files on a PC?

Premiere Elements 4 pretty much works with tape-based digital video. That would be video from a miniDV or HDV tape-based camcorder. It doesn't handle other formats very well.
If you plan to edit MP4s, you definitely want to upgrade to a more current version of the program. If you can't install a current version of the program, you may need to address issues on your computer (such as an outdated operating system or underpowered hardware configuration).
Short of that, you could buy Quicktime Pro from Apple for $29. It will edit MP4s, even on a PC platform.

I just purchased Premiere 13 and the video files won't play in Windows Media Player. I have audio but no video. What can I do? I have Premiere 12 and everything works fine with it.

What can I do?

What are your export settings for this finished video from Premiere Elements 13?
For example - are you using
Publish+Share
Computer
AVChD
with Presets = MP4 H.264 1920 x 1080p30
or something different like
Publish+Share
Computer
MPEG
with Presets = MPEG2 1920 x 1080i30
or something different ....
We are going to have to get at your export settings which gets us to the properties of the finished video that you are trying to play in Windows Media Player.
If you take your finished video from Premiere Elements 13 and import that into a new Premiere Elements 13 project with Add Media/Files and Folders,
does it import into the new project. And, when the video is in the new project, does it display video and have audio in the Edit area monitor?
We need more details of the properties of the finished video. Knowing that you have no problems with this matter in Premiere Elements 12 and that
the finished video plays in CyberLink are important, but they do not help to figure out what is happening in 13 so that it does not happen again.
