Videos YouTube does NOT play if media.mediasource.enabled is set to true (Youtube with HTML 5 Player). WHY?

When you watch videos on Youtube, I use the new HTML 5 player. It works fine when media.mediasource.enabled is set to 'false', but then I can't have the full experience because that lack of features!

If I let no. video will load, which means that I can't watch any video on Youtube!
As a solution, I installed the Plugin "Youtube Control Center" (missing in the list below). But it would be nice if I don't use this...

Even better would be if Firefox would be supported WebM. But this doesn't seem to be the case since YT uses exactly this Format with its new player... (And if I activate this media.mediasource.enabled (put "true") nothing works more.)

Firefox plays the 'old' WebM format in its default configuration (media.mediasource.enabled = false). You can check it out here: http://www.webmfiles.org/demo-files/.

What I've read, turn on MediaSource will allow you to play the "new" WebM on YouTube from Firefox 31. Even if preference exists in Firefox 30, I don't think that the actual code is there, which would explain why this ability to YouTube advertising causes the blackout.

  • Video Lightbox does not play in iFrame in Internet Explorer

    I built a site to include training videos with a widget (jQuery) composition in Muse CC.

    My site plays well on Firefox and Chrome, but in Internet Explorer, the video will eject and play on my Windows Media Player.  I had my team test in IE, and they had the same problem.

    Is that what I can do to make the videos only play in the compostion and the iframe and will not appear?

    EX: programs in school full time. Powered training team

    If you open the site in FF / Chrome, it works well.  If you open in Internet Explorer, a separate pop-up window plays the video.

    Any help is appreciated!

    Are the videos not supported anylonger? When I start this catalogue in LR5.7.1, the video works normally.

    (not quite the same catalog: catalog before upgrade to V6, so maybe the question is upgrading the catalog itself).

  • My copy of windows media player 11 does not play video.

    My copy of windows media player 11 does not play video. When you try to play the video (usually an avi file) I get audio and visualization. I tried to uninstall and install new, but does not. I chose also to all types of files media player by default but video still does not play.

    An avi file is simply a container that may have different types of files in it for video and audio.

    You probably don't have the correct Codec to play the video.

    Either download a codec pack such as K-lite or download a little program called G-spot, open it and drag your avi file in the center of the small window of G-spot.

    It will then tell you what Codec uses the avi file. You can then Google that particulat Codec, download and install it.

    See you soon,.

  • Cisco Media Player will not play my media after Windows 7 upgrade

    Last week I upgraded my operating system to Windows Vista Ultimate 64 to Windows 7 Professional.  I own a player DMP-100 which is directly plugged in my G from Linksys WRT54GS wireless router.  My computer is also connected to the router, so this problem is not a wireless issue, but it wouldn't surprise me if it turns out be associated with a.  When Vista was in charge, the DMP-100 router and Cisco Media Player is fine, although I had a devil of a time in the set up.  When I decided to upgrade to Windows 7 Professional, I realized because the BONES were inconsistent that the upgrade would eliminate all applications and I have to reload everything.

    When I rebooted Lela and the Cisco Media Player, I have none of the problems that I had with Vista in the configuration.  However for some reason, the program does not play my media files.  There is a default error message coming saying the Cisco Media Server can be turned off.  This is not the case.  More when I select a streaming radio station, the player, the server and software work fine.  I feel, but the server isn't really pointing to my library, the library opens upward in the software.  I unplugged and reset the player several times.  I also deleted and reloaded the server & software media a number of times.  I always get the same results.

    I don't like on radio stations.  I just want to be able to play my music and playlists. Anyone facing this problem before, and if so, is there a reason and a solution for this?

    (Mod Note: edited post for the respect of the directive.) (Thank you!)

    Eureka!  It's the firewall after all.  I thought I had everything checked when I added the AV Media Server and made sure the Cisco Media Player has been activated too.  Once I disabled the firewall and restarted, the press began to play as it should.  If something was definitely not right in the firewall.  It turns out that I was a fool and never saw the 'advanced settings' until I read about it in WIndows help (something I should have done at the beginning).  It was like a slap in the face.  Even if the programs were activated, there is no rule created for TCP and 8015 remote port.  It was clear as soon as I knew where to look.  I created a new outbound rule to allow TCP access port 8015, and the program worked as if it was never a problem.

    I want to thank you two people who have helped me through this and patience you while I flinched around this application and operating system.  It was a total exercise in frustration, but also that of the discovery.  I really appreciate your help.  I thank you and my audio system thanks you too!

  • StageVideo does not play content downloaded, but will play the included content. (iOS)

    Hi all

    I'm working on an application and try to use StageVideo and I came across a problem.

    I would like the app to be able to play H.264 videos on iOS.

    The video content to be played will be downloaded by the app from our server to the device.

    I ran my code under windows and android (specifically a xoom) and it works, so I know that the files are downloaded and paths are correct. However, when you run the code on iOS I was not see any video or hear all the sounds.

    I then tried including the video file when making the ipa and play from the included location and he play with sound and video.

    Can anyone think of a reason the video file will not play if it is downloaded as opposed to being included with the application?

    Including files video isn't an option because they change regularly, so need to be downloaded.

    Thank you

    Chris

    P.S. I post code if you need it, but I followed a little this code:

    http://forums.Adobe.com/message/4352118

    who is responsible in a view empty.

    Thanks for your help.

    I got it to work. My problem was that the app was the creation of the local file using our address of the server, for example ' video/1100', what I knew was a video, so I would spend it in the StageVideo who don't know what to do with it. The solution was to add ".mp4" at the end of the location of the file for example "video/1100.mp4" so that StageVideo could open.

    When I got it with the app, I was using the original file named "example.mp4", so he was not having this problem.

    By the way, I ended up going with StageWebView for my solution, because it is easier to design my app round have a video in the forground to require a gap by everthing in the background.

    (StageWebView also has the problem that I found above where it takes a file extension to play).

  • I have firefox 13 and 15 but realplayer download this video option does not work, extensions to save plugin is disabled, if no videos do not play in youtube

    I have Firefox 13 and real player 15, but the download this video option does not work, under extensions to save browser plugin is disabled, but if active videos do not play in youtube, error occurs, it's major drawback, it works well with IE, but I prefer Firefox so any help to rectify the issue is appreciated.

    One possibility is to upgrade to Flash 11.2 and re - activate the Plugin RealPlayer browser Record extension in the Add-ons Manager (Tools > Modules > Extensions) (it's a softblock).

    If you need to return to 11.2 Flash you can download Player Flash 11.2 through this direct link:

    You must uninstall version 11.3 Flash.

  • Can Windows Media Player XP play MTS file type? I tried, but the video does not play smoothly. Is this fix really?

    I tried, but the video does not play smoothly.  Is this fix really?

    There is a possibility that Windows Media Player could
    read the file if you rename the MTS to MPG or AVI.

    And/or...the suite of freeware Media Player can be
    worth a try.

    (FWIW... it's always a good idea to create a system)

    (works on XP/Vista/7)
    (The name of the file to download is: "MPC - HomeCinema.1.5.2.3456.x 86 .exe ')

    If this fails, it may be worth trying to convert the MTS file
    WMV format:

    There are many converters available on the net... some

    Once installed... Open Sothink and go to... Add the files button...
    Find and select the clips you want to convert.

    Next... in the encoding settings... Choose... Video credits.
    WMV - Windows Media Video (*.wmv).

    Choose an output folder and on the left, click on the button convert.

    You can experiment with other settings later but
    This should help you get started.

    First, you will need to decompress the file or just open the

  • HP Pavilion dv7 Notebook PC does not play video streaming

    Hi-

    I have a brand new HP Pavilion dv7 Notebook PC, Intel (r) Core i7-2630QM CPU, 8 GB, Windows 7 Home Premium operating system, Service Pack 1 64-bit. Beats audio, Radeon graphics card

    It does not play Netflix streaming - the screen is dark, even though the video seems to play, and there is no sound.

    It does not play videos YouTube - video playback but the sound is off. It goes the same for Megavideo and other streaming services.

    On the other hand, he plays the music very well on the native Windows Media Player. I have not tried video on my laptop.

    I make me quite frustrated and don't know what to do. Does anyone have an idea if this is a problem of HP, beats, or Windows 7 (or a combination of all three)?

    At this point, I am considering doing a restore of the entire system and starting from scratch. Any help is appreciated.

    Eihalcon, welcome to the forum.

    It seems that you have not installed Adobe Flash Player .  At least, I suggest to start with that as a possible solution.
