• videos won't play

• BlackBerry passport when viewing a video on Facebook or Youtube, speakers stops playing suddenly

  Hello

  Hope someone can help me with this... Just got a new Blackberry passport a week ago, coming from an iphone 4 s. I have play videos on Facebook and Youtube and after a few seconds/minutes a VERY STRONG high pitch sound (more like a whistling noise) suddenly burst speakers, then slowly his is dimishing and after a few seconds, no more sounds of Blackberry coming out of speakers. The music plays, but no sound, even for the videos and key tone. I need to reboot my bb for my speakers to work again. What happens here?

  Thanks for you help in advance!

  Frank

  @frankviolette506 you play the in the browser? or in the apps?

  It shouldn't make a difference, but it might help to determine where the problem is.

  My Passport works perfectly for videos on OS 10.3.1.1581.

  Some things you can try:

  (1) I wish to usse BBVE, which comes with your device. Launch the tool, select the Center button, which will give you a list of tests and run the audio tests. He will perform a few tests that allow you to test the speakers, etc.

  If one of them fails, I would first reload the OS using the software Link. Then rerun the tests. If they still fail I guess a hardware problem, I hope still under warranty.

• BlackBerry Smartphones YouTube videos do not play/Adobe Player

  I have a BB Torch 9810 and I tried to play YouTube videos and it says I need to update my Adobe Flash Player but when I arrived on the site of Adobe Player it says that the update is not supported by my "operating system or browser." What should I do?

  First, very few phones that support Adobe Flash, at least you're in good company.  If you go to the mobile site of youtube, you should be able to view videos.  It is found by typing m.youtube.com on your phone's browser.

  I hope that clears things up for you.

• Videos don't play do not (including recorde Whatsapp, videos, Youtube, Twitter, etc) since the iOS 10 updading

  From time to time, all types of videos would stop playing on my iPhone more including Photos videos 6s, Youtube, Twitter, Whatsapp and everywhere else. He would return to normal only with a reboot. Closing force all the apps won't help, switch networks, locking and unlocking or anything else. I have iOS 10.0.2 and all applications are updated.

  It's so boring please help!

  Hi there, Awartany_Dubai!

  Thank you for reaching out by Apple Support communities. I understand from your post that you have intermittent problems watching videos using various platforms (those you make on the phone itself, YouTube, Twitter, etc.). I watch a lot of videos on my iPhone, I'd be happy to help you!

  Looks like you already have a few to start great troubleshooting steps. Since force close your applications, evolution of networks and rebooting did not help, I would recommend backing up your iPhone, and then reinstall your software iOS.

  You can get the measures to save here: How to backup your iPhone, iPad and iPod touch

  Once which is finished, use this article for instructions on reinstalling iOS: If you can not update or restore your iPhone, iPad, or iPod touch

  Even if the title of the article is not exactly specific to your problem, the steps under "putting your device in mode of recovery and put up again" will guide you in how to reinstall software iOS to help solve your problem with videos.

  See you soon!

• After the last update of Firefox, youtube videos do not play. The answers I've found are not relevant or too complicated.

  After the last update of Firefox, youtube videos do not play. The answers I've found are not relevant or too complicated.

  Hi Cbella, YouTube is generally used with an HTML5 player, who is a player who does not use a plugin video in MP4 format (for example, it does not use the Flash plugin).

  Now, I based this assertion on Windows, Mac may vary.

  Could you do two tests for me?

  Test #1:

  To verify which player you see (which does work), try a right click or Ctrl + click on the YouTube Player and check the "context menu" that rises. If it's the Flash, there will be a menu short, referring to the Flash on the last line. If you do not see that, if you get a regular menu of Firefox, it's probably the HTML5 player.

  Are what player you?

  Test #2:

  If you open the following test page, which videos to play?

  http://www.quirksmode.org/HTML5/tests/video.html

  • The video "H.264/MP4" play?
  • The video "WebM" play?

  Thank you.

  Also, you can check if your Flash plugin is up to date? You can use the site Mozilla Plugin check for this (please ignore the other plug-ins page wants you to update at the moment avoid making the situation more complicated):

• Whenever I play youtube videos, they shake from left to right and to go at different speeds.

  I have windows 7. A couple of days, I went to play youtube videos and they all shake from left to right and go at different speeds (very erratic). This ONLY happens with videos from youtube (HTML5). When I play other videos(non-HTML5), they play very well. Also, the sound on youtube videos are fine, only they do not match the mouth (s) of people talking. The mouth move faster. I've checked all my plug-ins and everything is up-to-date. My firefox browser is also the last version. I did a malwarebytes scan and it came up with nothing. All the settings on the youtube videos are also where they should be. It happened for about 5 days. Can someone help me?

  Thanks Guigs. I followed your instructions and found out it was a 'acceleration hardware problem' that was the origin of the problem. I unchecked the box and YouTube videos play very well! Thank you for taking the time to help me.

• Why the latest Firefox won't play YouTube videos

  Everything worked fine until the latest version of Firefox, now I can't play YouTube videos. No problem with Chrome or IE. Firefox screwed up something with their latest version. Problem started on 09/03/15.

  1) enter the config by typing about: config in the address bar.
  (2) enter media.mediasource.webm.enabled press ENTER.
  (3) make a right click on it and change to true, for some reason any, defined as 'false', which makes the MSE & WebM VP9 does not work correctly.
  (4) visit: https://www.youtube.com/html5 and check that everything is OK.
  (5) tries to watch a video. It should work now.

• Playlist of YouTube videos will not play always more

  I have Win 7 and FF 18.0.1 the problem I have is recent because it used to work very well.

  When I go on Youtube and want to play a playlist of streaming videos, it plays not always more. When the video page appears that it appears with a red circle "BOLD" and a backslash in it and as soon as I move my mouse over the video portion of the page the red circle goes away then I have to click on the play button in the center of the video page to play. He then played this video and stop. So I go through the same thing again to get the next video to play when all the videos should play without interruption until all are played and this is how it used to work until very recently. I'm guessing that I added a FF add on that is causing this problem. This has happened for a few weeks and I thought nothing about it until today when I tried to play a continuous loop of videos and now I don't know what to add ons that I recently added. Of course, on that I do not know that a FF throw causes this problem. I can play the same playlist of videos with Internet Explorer and they play the way they are supposed to play continuously.

  Thanks for the ideas of all. Some time has passed since I had this problem so I don't know what was the cause. However I think that it ended up being Flashblock. In any case, I noticed that I uninstalled Flashblock. I'm not sure but it seems that it's the first thing I uninstalled and it does not solve the problem. There heck of 81 and I remember even back a month ago and a half what has been done to solve this problem. Sorry about all the...

  Thanks to all those who had suggestions.

• Adobe Flash 11.4 installed on pc, but does not appear in the list of modules additional plugin. flash or youtube videos won't play

  Hello
  I've updated to the latest version of flash player 11.4.402.287 today, the two versions of activex or plugin appear in flash Manager. However, I'm unable to play youtube flash videos, the bar at the top shows "Install missing plugin" I repeated the installation process, it does not appear to complete successfully, but even once when trying to play youtube videos, the "install missing plugin appears" and the videos will not play.

  I have also installed and re installed the last version of firefox today, thought that can help, seem to have the same problem. The flash player is not listed in the plugin adds on the list. I don't know what else to do, or what could be the problem.

  I would appreciate any advice, please

  Hello, I think that the download of the flash 11.4 for windows on the adobe site includes 32-bit versions and 64-bit plugin, for which I hope should not be the issue. can you try the troubleshooting tips that were offered in the following thread (step by step) and see if that can solve the problem: https://support.mozilla.org/en-US/questions/937543

• After the upgrade to 16.0.1 some just Youtube videos won't play. They work perfectly in Chrome.

  After the upgrade to 16.0.1 some just Youtube videos won't play. They work perfectly in Chrome.
  A few examples:
  http://www.YouTube.com/watch?v=rQpldNJXuP0
  http://www.YouTube.com/watch?v=-e-BRki7gwU
  Most of the videos works perfectly, so I can't say what the problem is.

  I have tried so that the first thing, but it didn't work at all.
  Anyway, I solved the problem in the meantime by uninstalling Firefox and put it back. Please note that I had to do a CLEAN install, and I mean by 'clean' that I had to remove the settings as well. First I tried to reinstall it but I kept the settings (Firefox will ask if you want to keep when you uninstall) and it did not work. I therefore saved bookmarks and uninstalled everything. The later resettlement has solved the problem.
