MP4 files won't play in mobile browser?

I have a media file, MP4, which plays fine on desktop browsers. But on the iPhone4 and on Android 2.2 mobile devices this media file won't play within the browser. I get a broken link where the embedded video should be playing. I am using proper object/embed tags per a previous successful attempt I made doing this and I cross referenced my classid to one that was posted online to make sure I didn't miss any syntax. What could be going wrong? Did I encode the mp4 incorrectly? If so, then why does a 3gp file that I rendered FROM the broken mp4 play within the mobile devices without a hitch?
Sincerely,
markerline

Are you sure you have Photoshop Elements 8 and not Photoshop Premier elements 8? I would have thought that MP4 files can be played in Premier elements (PE) rather than Photoshop elements (PSE). PSE is for photos and PE is for movies and videos.
Perhaps you could try installing the trial version of PE13 to see if anything changes. I am not into movies and all that so my answer is just a guess work.

MP4 files won't play in PSE 13 but will in PSE 8 on same PC

I just upgraded to PSE 13 on my Windows 8.1 PC, but none of my MP4 files with MP4V video will play in PSE 13. I get an error dialog saying that I don't have the "required codec installed". This is not the case because I still have PSE 8 installed on the same PC and it plays these videos fine. These files also play fine in both 32-bit and 64-bit Windows Media Player so what is wrong with PSE 13? This seems like a bug in PSE and I don't want to install Quicktime on my PC.

Swf files won't play in IE7 browser window

I am using Windows XP Pro and I have updated the flash
player, yet any webpage ending in ".swf" won't play. It did not too
long ago though. Any ideas on what could be wrong?

When I Generate, the link points to file:///c:/users/...../www.[website
address]file.swf
<file:///c:\users\.....\www.%5bwebsite%20address%5dfile.swf> . It's looking
for the file in the generated project, but it looks confused. J
I looked to see if I could import the files, but there doesn't seem to be
any import for swf files.
Can I simply put them in the directory with the project files, and point the
link that them there?
I don't want to publish to see what it's looking for when it's published,
since it's a client's site, and I don't want them to see something that
isn't working.
Thanks!

Swf file won't play automatically in browser

I am creating a website using flash, photoshop, and
dreamweaver. When I import my flash swf file into dreamweaver/save
it and then open in browser to see if my file works it does if you
right click it. How can I make it automatically load when my page
is opened? Do I need to give my flash file an actionscript to tell
it to play when the page is opened? If so what is it and where
should it be on my timeline? Please advise.

swf files will play automatically once they are loaded. this
may be an IE issue - you may need to use AC_runActiveContent or
SWFObject to 'embed' to resolve the problem.

My .MP4 video file won't "play video full screen" in Muse after I publish my .OAM out of Edge Animate.

My .MP4 video file won't "play video full screen" in Muse after I publish my .OAM out of Edge Animate. When I "Preview In Browser" through Edge it plays (I have created a shape and used the "play video full screen" snippet) in full screen mode just fine. When I "Preview Site In Browser" through Muse and click on the shape to PLAY VIDEO FULL SCREEN, it does nothing. I am new to both programs and can't figure out why it will work out of the preview window in Edge and won't work when I publish to Muse. Does anybody have an answer or a work-around for me?

Videos won't play in any browser

Just recently, videos won't play in any browser...Safari, Firefox. etc. It seems to happen with .wmv files. I reinstalled media player, but still have the problem.
I get this message.
"Cannot open the file. Verify that the path and filename are correct and try again"

First, check that Windows Media Player is set as the correct plug in - in Safari, go to help/installed plug ins. There should be a section marked 'Windows Media Player' showing 'application/x-mplayer2' and listing wmv files (amongst others).
Sometimes these arrors are caused by DNS failures. Ensure your system is fully up to date, and enter your ISP's DNS server IP addresses (usually two of them, sometimes three) in the 'DNS servers' box on the TCP page of the Network preference pane.
The DNS server IPs are usually supplied with the ISP's initial set up documentation, or located on the ISP's help page.
The reason it could be a problem is that in many iterations of MacOS X, the system is extremely sensitive to how quickly a DNS search responds. DNS is the process whereby a user-provided URL is converted into the correct IP address for internet lookup, so if the video source is held on a different server and the DNS process doesn't return a valid IP address in time, you would then get an error of the sort you describe.

Presenter 9 after I publish the file won't play on my computer

Hi,
Quick version- presenter 9 won't play a published file. It starts the viewer, but the green circle just spins.
Details-
brand new computer, fresh download of presenter 9 today.
Win 8.1
office 2013
Firefox browser
FIle created in Presenter 7 on aother computer, copied into a new computer (along with all the resource and data and so files).
it's long, about 45 min
I am able to preveiw the entire thing- audio works, embedded shockwave demos created in captivate work. It just won't play in the browser. I've tried both 'view output when complete' when I'm publising it, and just manuallly clicking on the index file after it's published. neither works. I also tried using explorer but that was worse- it leaves a white screen without even loading the viewer.
just to test I made a new presentation with only a couple slides and no audio. that will publish and play in the browser properly.
I have the latest flash and shockwave.
It seems like it should work since it previews fine.
any ideas??
thanks!

Hi Sunil-
I watched the global settings video and added my C: drive and also the entire 'my adobe presentations' and the indivisual file for this presentation to the allow list. It didn't help. is there something else I need to do on the flash settings other than this 'allow' list? (picture below).
The other option you mentioned was transfering using a package. my old computer has Presenter 7. I don't see in that version of presneter an option to create a package. I can try that if you can tell me how to do that.
finally, if i would need to share a file with you how would I do that? it's a 24000 KB file.
thanks for the help!

HD movie and tv show files won't play in iTunes 10.6.3.

Just did a fresh install of Mountain Lion and for some reason now HD movie and tv show files won't play. I get a black screen.
Standard Def tv shows and movies are still playing fine though.
Oh and yes I already tried switching it to 32-bit mode via the "Get Info" screen. Same problem results.
Any suggestions?

I think I have the same problem. Every time I play some HD movies in iTunes the movie seems to be stuck and the screen black. If I scrub the movie forward I can see the picture, even captions, but I can't play them. I said some because there are certain movies that DO play. I mean HD ones, SD video plays fine. But I couldn't find any clue. It's not a matter of file size, neither a matter of resolution, compressio... I'll wait for an update (system and/or iTunes) and if nothing happens I think I'll dig a little more. This is no big issue for me since they ALL seem to play perfectly when I select AirPlay to my Apple TV.
I'll try checking tags

.3g2 files won't play in any media player

Hello.
Ever since we updated to OS X Mavericks, any old .3g2 files won't play in any media player on our iMac. When we go to play them, they play button in QuickTime just flashes from pause to play and then back to pause and and nothing happens. I'm not sure if this file type is becoming outdated and therefore is not compatible with the new OS X, but I am just curious if anyone knows if there is a way to fix this.
Thanks.

Did you try VLC?

Wav files won't play in Firefox 22

Wav files won't play in Firefox 22. Previous versions of Firefox are fine. Other sound is fine. I have the latest mac OS X. Quicktime is set to play wav files. I have the latest version of it.
Is there a fix for this?
Is there any other plugins I can install which will play the wav files?

Thank you for your response Alice.
I checked about:plugins and I DO have audio/wav and audio/x-wav. It it QuickTime 7.7.1 I have.
In Firefox Preferences Applications Panel I do not seem to have the iTunes.Document audio/x-wav there, only the audio/wav and Waveform Audio.
Re the New Email Notification feature with my Webmail, this is not activated via a Firefox extension. I don't really know how it works but when I'm logged into my Webmail email account and a new email arrives, a wav sound is played to alert me of the new email. This has always happened with all previous versions of Firefox, just not since I updated to Firefox 22 but when I go back to Firefox 21, it works again.
I have previously asked about this with my Webmail company. They knew nothing of this problem. I have now asked them for a second time now that I know that it is only THEIR wav sound that won't play. Other wav files play OK with Firefox 22.
I do not know what is at fault - Firefox 22, QuickTime or the Webmail site but for the past few days I have frequently switched between Firefox 22 and Firefox 21. Each time the New Email Notification wav sound works with Firefox 21 and doesn't with Firefox 22 so that makes me suspect that somehow Firefox 22 is at fault.
But it is a mystery and I might be stuck with it - unless it disappears as mysteriously as it arrived with a newer version of Firefox or maybe even a newer version of Quicktime.
Thank you to everybody who has tried to help me.

After a itunes update my HDV mov files won't play on my mac.

I applied and update to my MacBook pro and BAM!! Now my HDV.mov files won't play with QuickTime or final cut pro. I'm in the middle of a project and I can't finish it because when the files play in fcp I get a error. Can anybody help me with this?

I have two anserws I think might work for you. The first one is: This solved the issue down loading and re-installing Quicktime 7.5.5
http://www.digitalrebellion.com/blog/posts/using_pacifist_to_downgrade_quicktime .html
I'd create a backup of the System / Components and Quicktime folders first though, just incase you need to revert back.
and the 2nd one is:
I HAVE A FIX...AND IT WORKS!!!!!!!!! Actually a friend found this fix somewhere else, but I just did it and it worked. The only rub is you need to have access to another system that has not been updated to iTunes 10.5 or QT 7.7.
On the system that has not been updated, go to:
MAC HD/System/Library/Components and copy that folder to an external drive...next go to
MAC HD/System/Library/QuickTime and copy that folder to an external drive.
On the system that is not working, go to the same places on the MAC HD and delete those two folders. Then copy the folders from your external drive to the same location. Restart you system...i did it twice...and everything should be back to normal. This has worked on both systems here that were previously jacked up. If you do not have access to a system that was not messed up, let me know and maybe we can swap files.
I havent tried any of these yet because I'm in the middle of a project and I dont wnat anything to go wrong right now. After I'm done I will be sure to get started on one of these.
If you try any one of these let me know how it works out.

IMovie Audio Files Won't Play when the File is Moved

I imported a lot of audio files into iMovie from my desktop and I set them out how I wanted them in my project. But as my desktop was getting too cluttered, I had to move the audio files into a different folder in my documents, but now the audio files won't play and a warning icon is on each audio clip. Is there a simple way to relocate the files, without moving the files back to my desktop and without having to set out my all my audio files all over again?

Besides the two files you mentioned in your post, you also need to upload YOUR .swf as well. Then you need to upload your music file/folder.
Also double check that the path to your mp3 is correct RELATIVE to the location of the Web page that you placed the .swf on, NOT the physical location of the .swf.
var req:URLRequest = new URLRequest("../Sound/dreamsSound1.mp3");
This needs to be the path from the WEB PAGE to the mp3, NOT the path from the physical location of the .swf.
Once you have the pathing correct, it should NOT work when testing in Flash CS4, because the path to the mp3 needs to be RELATIVE to the Web page.
Best wishes and Good Luck!
