Html5 video

hi,
I have issue to read html5 (to be more specific <video> tag) on iPad.
I'm trying to watch a live event (in our lan) with iPad and I get only black square without any "start" icon.
I don't understand because it works well on iPhone and iPod... only iPad has isssue.
Workaround is just to put a link <a href... to the live video to get it working on iPad.
Live is streaming from wowza server and file is m3u8 file, and I repeat no issue with iPhone/iPod
Even tested on iOS5 without any problem on iPhone/iPod.
If you have any idea that would be great.
Best regards
Nicolas

When I say it works on iPhone/iPod I mean version 4

Safari version 7.0.6 (9537.78.2) won't play html5 videos. (Mavericks on Macbook Pro)

Since upgrading to Safari version 7.0.6 (9537.78.2), html5 videos will no longer play. (Mavericks on Macbook Pro) I get the error message "Please upgrade your browser to view HTML5 content". The only extension I have is ClickToFlash. When I disable it, I get the error message immediately without having to click on the "Flash" button to give it permission to run.

same thing for me... yesterday i started noticing flakey graphics on video playing, then went shopping on Amazon which kept telling me to upgrade my browser, and when I check the link to safari update, I am greeted with I have the latest version of safari. I checked my Last Yosemite update... it is current.   I rebooted my computer went to bed, and today, nothing on Yahoo, Abc News, youtube will play when it comes to video.   A conspiracy in the making to take down or disrupt all apple users I am sure must be going on.    I say this because I checked another iMac which has been working flawlessly.   And update to flash came in, I did not perform that update.   Videos worked fine.   That update was done and bam... no video playing on that computer either.
I think Apple should release something immediately and stop anymore flash on mac updates to be installed.   Adobe needs to be notified that what ever they have released is killing all apple users who use safari.
ANYONE READING THIS BE AWARE THAT THE LATEST FLASH UPDATE PROMPT WILL KILL YOUR MAC SAFARI AND VIDEO PLAYING ON SAFARI WILL END.   AMAZON and OTHER SITES WILL TELL YOU YOUR BROWSER IS OUT OF DATE, IGNORE THAT BECAUSE I THINK WHO OR WHAT EVER COMPANY IS BEHIND THIS HAS BEEN WORKING INSIDE WITH THOSE COMPANIES ALTERING CODE SO THAT PEOPLE ARE DRIVEN TO START UPDATING SOFTWARE IN HOPES OF SNAGGING THE UPDATE FROM ADOBE THAT CAUSES THINGS TO CEASE WORKING.
TODAY Both IMACS Running YoSemite will not play video and are both crashing with Graphic Hardware errors... 2 iMacs that are 2 years apart on Manufacture date, and both were working flawlessly this past weekend.

Safari 5.1.2 Youtube HTML5-Video issues

Fullscreen-Button on Youtube doesn't work for HTML5 videos on Youtube in Safari. Also there are problems with the video performance. The process QTKitServer Safari Webcontent has 105% CPU, the whole MacBook is very slow in that moment.
This is only a problem in Safari!
Since three years i use Safari for all my work on the net. But after the upgrade to Lion, this browser has a lot of bugs and getting slower and slower. I think it is time to change the browser. :S

Yes. I have the same problem as well. Watching a video on Youtube and the process called QTKitServer goes above 100%. I haven't figured out why (html 5 or fullscreen or whatever) but I didn't noticed it before.
Macbook, Snow Leopard, Safari 5.1.2 with only the Adblock extension running.

Safari 5.1.2 doesn't play HTML5 video

I'm developing a website which uses HTML5 video as a fullscreen background. At home, I'm developing on a MBP running Snow Leopard. At work, I'm using Lion with Safari 5.1.2.
Currently, the page displays fine on Safari/Snow Leopard, Chrome/OSX, Firefox/OSX, IE9 (what?!), Chrome/Win and Firefox/Win.
Safari 5.1.2 on Lion and on Windows will NOT play the video and instead defaults to the poster image I have set.
The video has .mp4, .webm and .ogv versions for all the supported browsers.
I have tested this by downgrading my Lion computer to Safari 5.0.5 and the video played perfectly.
Any ideas? Seems like people are having issues with 5.1.2 and YouTube HTML5 videos also.

I believe you..
At home, I'm developing on a MBP running Snow Leopard. At work, I'm using Lion with Safari 5.1.2.

Safari 5.1.7 Beach Balls when displaying HTML5 video

Hello all,
I'm coming to you guys with an extremely annoying bug in Safari 5.1.7 (it's been fixed in 6.0, but Apple won't update Snow Leopard machines to the new version).
I have an HTML5 video at http://safaba.clients.numonium.com that is supposed to play above the homepage slideshow when you click the play button in the first slide (the slideshow fades out, video player fades in).
This aforementioned works properly in the following browsers:
Firefox (current version - 16.0.1)
Chrome (current version - 22.0.1229.94)
Microsoft Internet Explorer 9
Microsoft Internet Exploer 8 (uses SWF fall-back, but properly transitions to the video and plays the SWF)
Safari (current version - 6.0)
Safari for iOS, iPhone
Safari for iOS, iPad (you have to hit the "play" button twice to get it to play... another issue)
You can use the following credentials to access this site:
http://safaba.clients.numonium.com
User: apple
Pass: FQscoPxhx!
Safari 5.1.7, however, completely goes unresponsive under some circumstances, inconsistently:
When you click the "play" button on the first slide to launch the video player
If the above works, the video might play for two seconds then go unresponsive
If the above works, the video might play until you seek
If the above works, the video might play until you send a scroll event
The browser sometimes (albeit rarely) plays the video flawlessly, but only once completely loaded. If the video does, in fact, play properly, clearing the cache would revive the aforementioned issues. Therefore, I think this bug has to do in how Safari loads the video upon page load.
I've done just about everything I can think of (if I go to the video directly - http://safaba.clients.numonium.com/images/videos/homepage-slideshow/homepage-sli deshow.mp4), the video will play after a few seconds of loading.
So I would greatfully appreciate any and all help anyone can offer - thanks!

I should also mention that when Safari beach-balls, I don't see CPU, bandwidth, or Disk I/O spike (in fact, they're all close to 0), and only about 50% of the computer's RAM is used.
Thanks again!

HTML5 Video Works In Live and Preview But Not on My Website

I feel totally ripped off by Adobe, again, I talked to a sales representative who told me that if I bought CS6 I would be able to easily install html5 video because the new version had an insert function that did most of the coding for you and gave you a properties view to select alt source... Now, I find out that is only available in the Cloud version. What a bunch of ....
Anyway, I can't get my video to play in IE, but it works fine in FireFox. I am using Windows so don't know about Safari. The live view and the preview in browser video works just fine but when I upload it to my site the webpage with the video has a space where the video is with dotted lines around it, but it is empty. The control panel flashes for a second but disappears. The video file is there in three versions. I check the MP4 version and it works fine, as I said it works in the preview IE browser.
Any ideas? Very frustrated, I figure if I had the properties view or could have inserted the file via HTML5 video command it would probably work.
Here is my code:
<video id="0" preload="metadata" controls width="640" height="460">
        <source src="FunWithMyFriend.ogv" type='video/ogg; codecs="theora, vorbis"'/>
        <source src="FunWithMyFriend.webm" type='video/webm' />
        <source src="FunWithMyFriend.mp4" type='video/mp4' />
        <p>Video is not visible, most likely your browser does not support HTML5 video</p>
      </video>

Thanks Nancy, you're sure right about the user - I am a newbie and quite ignorant yet. I am a Linux user through Host Gator (not so good btw - slow over-crowded servers). I checked and added the basic MIMEs that I am trying to play. h.264, mp4, mov, ogg (OGV), WEBM, even wmv.
Here is the page - it is 3/4 of the way down the page where I try to include a graphic file that won't play in IE9 but will in Firefox and Chrome.
http://christopherproductions.us/Graphics.html
I tried reconfiguring the MP4 file several times using all sorts of settings here is the most recent versions and my code on this page. Note on the webpage below I explain that the Sony Movie Studio forum suggests saving in MainConcept AVC/AAC (*.MP4/*.AAC) Internet HD 720P codec   I also tried saving in WMV and then using Freemake to convert the file to HTML5 (it makes three files, obviously the ogv file works in Firefox, I don't know about the WEBM file, but it looks like the mp4 file doesn't work, that is why I made one file specificially for mp4 using Movie Studio to render it.)

Thanks to anyone who helps - I really appreciate it.

Is there any way to View video with HTML5 video browser, as from wikipedia articles, on my IPad mini?, Is there any way to View video with HTML5 video browser, as from wikipedia articles, on my IPad mini?

I do a lot of research using Wikipedia articles. Sometimes those articles have video attached. When I click on the play button of the image, it opens a floating window with the first frame of the video, but it's not moving. A thin banner at the top of it me: "For a better video playback experience we recommend a [ HTML5 video browser". And touching the play button ( hoping it might play anyway) has no effect. It will not play.
Is HTML5 a PC/Windows only format? Or is there an App that will alow me to use these videos on my iPad mini? I've spend 6 hours already trying to find out what I can do about this, and I've made zero progress. I've checked out a handful of apps in the app store, and don't even know what I'm looking at. I got the Wikipedia app for mobile devices, and it doesn't offer the videos in the truncated articles it provides. I've spoken to several Apple techs at the Applecare phone number, and no one there seems to know anything about it.
surely, I can't be the only one with this issue. Please comment, please help. Thank you all.

Dear Bob,
I downloader a VLS Streamer from the Apple app store. It requires some kind of helper software to run, which, as far as I can tell from the video at the developer's site, allows one to download content from one's mobile device to their computer. Since I don't have a compatible computer for my iPad to link to, the instructions don't help my situation. I emailed them with my query and will probably hear from them sometime this week.
I've lived with this problem for the 3 months I've had my iPad, and I'll keep after it until I have a solution. But right now, I've run out of steam. If this lead helps me to resolve my issue, I'll come back and HELPFUL or RESOLVED every response you've given. I'm very grateful for your help. Sorry I'm so utterly clueless.
Thanks once again. Please don't cringe if I get back to you another day.

Trying to create HTML5 Video Playlist in Edge Animate - I can't get it to work. Please help!?!?

Hi All,
I am creating an interactive site through Edge Animate and am in the process of trying to create a HTML 5 Video Playlist to function within Edge Animate.
Current Process - Example:
I have 3 videos that need to be played on a certain page.
I created a symbol and dragged the videos to the stage and hidden them within that symbol's timeline.
I then use thumbnail images in a side playlist to either .remove(); .hide(); a video and .show(); the next.
However when I do a hide / show option, the video continue to plays in the background if I don't also create an if/else statement to pause it.
My concern with pausing it is that it will continue to load and dramatically slow down the load time of the site.
References:
I found this which looks very helpful but don't know how to add this to edge composition.
http://demosthenes.info/blog/909/Create-An-Automatic-HTML5-Video-Playlist
Please help or put me in the right direction to create a playlist would be hugely... AMAZINGLY.. helpful.
Thanks,
Jason

Hi Joe,
Thank you so much for your help on this one. It is hugely appreciated!!
I have been working frantically to implement your solution to get this working. I used the 'change src' method.
I have added all my code below in case anyone wants the solution in the future.
Could you please help below as I am now totally stuck with the <track> and 'event listener issues' !!
Issue #1:
I am having major problems with loading the 'closed captions' track element.
Everything I click for the video to change source / to the next video, the closed caption track adds to the video and doesn't 'unload' the previous one. You then end up with multiple different subtitle tracks on the video screen
- The closed captions / subtitles are not showing up in Google Chrome either?
Issue #2:
I can't get the event listener in edge animate to work for 'playing' and 'ended'. Can you please help and point me in the correct direction??

Safari with 10.7.3 -Still no Screen Sleep Fix on HTML5 Video

Yesterdday 10.7.3 was released with new Safari and there is still NO fix for the Full Screen Sleep issue with HTML5 Video, whats wrong with you Apple, this bug is since Lion released with Safari,5.1 now 3 Versions later this small bug is still not fixed, but already known, i dont want to use Caffeine or such stuff, while Apple sugggests the Web to use HTML5 why is the support for basic Features so bad?

Solved!
A Workaround:
Get the Webkit Nightly Build , download and add to your App Folder, make it the Default browser, follow the instructions to show your homepage, after this you almost done, than download
RCDefaultApp, open System Preferences launch RCDefaultApp, go under Apps, search for Webkit and mark all all associations, Safari is no more dfeault for something, after this, go to Extensions Pane and search for the safariextz Extension, now set it to Webkit as well, now you are most up to date and Webkit updates more often than Safari ever did ^^
Enjoy

[Solved] dwb can't display HTML5 videos

Hello,
I have discovered dwb, which really interests me as a lightweight alternative to massive browsers such as Chromium. However, I don't use Flash (bleeehhhh), and I've discovered that I could not display HTML5 videos (only with dwb, that is, because Chromium does fine).
As an example, the Vimeo player (which is HTML5-based) displays this message: "Major bummer. The video can't be played with your current setup". I must add that I use dwb-git, and according to the wiki's instructions, I ran this when I noticed the bug:
sudo pacman -S --needed gstreamer0.10 gstreamer0.10-bad gstreamer0.10-bad-plugins gstreamer0.10-base gstreamer0.10-base-plugins gstreamer0.10-good gstreamer0.10-good-plugins gstreamer0.10-ugly gstreamer0.10-ugly-plugins gstreamer0.10-ffmpeg
Here are the user-agent strings compared. The main difference is the lack of image/webp acceptance in dwb.
# Chromium

I have searched dwb's website, which mentions the use of youtube-dl via an userscript. If I'm not able to fix this, I'll use the script, but in-browser videos would be more comfortable. I stumbled upon this bug report, so my hopes aren't that high ... Could you help me sort this out ?
Thanks in advance for your answers

The mods can merge it into the dwb thread. You're more likely to get a response from the person who developed it in the dwb thread.

It's flash, as already stated in the dwb thread just recently. I will install this gst-libav to see what I get.

Need help with coding for HTML5 Video with Flash fallback

Hello, need help with my coding in Dreamweaver CS5.5 for HTML5 video with Flash fallback. Not sure if the coding is correct. Do I need anything else Javascipt etc?

The reason you see a blank page is because it's trying to load the file that is pretty humungous and there is no preloader. So, you see a white screen till it complets loading.
Also, the reason why its loading a SWF file and not any of HTML5 type video is because your doctype declaration is XHTML1.0 and not HTML5.
Change the 1st line in your .html file from:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
to:
<!DOCTYPE html>
Then see if your HTML5 video types load with <video> tag.

Firefox is hanging when the page scrolls down to a html5 video or the page to a slideshow with fade effect

Every time a page has a html5 video or a slideshow with fade effect Firefox 3.6 becomes terriblely slow. It freezes with this test: http://demos.hacks.mozilla.org/openweb/HWACCEL/
I have Fedora 14 and before that Fedora 13 and the problem happens with both.
The same doesn't happen on Opera or Google Chrome.
'''UPDATE 1''': I have already tryed the Safe Mode and the problem happens the same.
'''UPDATE 2:''' This page full of videos scroll smothly without any problemas: http://brettgaylor.tumblr.com/tagged/webmademovies

I forgot to say that I did tryed the Safe Mode just to see if the slow was not being caused by some extension or plugin. However the result was all the same. By the way, the slow happens even if there is only one page opened. I am not thinking it is something related to the ATI video card or even Fedora because the same slow does't happen in Chrome and Opera...

Safari 6 lost audio in HTML5 videos

I used to be able to play HTML5 videos in Safari without a problem--but as of the past week or so, I get no audio. I did a couple of courses through Coursera this summer and the HTML5 videos worked fine. But now that I've started new courses, I have to use Chrome (which I don't like) or use the Flash versions of the video which are not as good. Anyone else encountering problems with HTML5 videos audio?
I've seen older posts about Safari not playing nice with Youtube HTML5s; but that's a long time ago and my Safari was working fine with HTML5 until the last week or so.
My MacBook Pro is mid-2012 and running : OS X 10.8.4 (12E55)

I was just searching for a solution to this exact problem before posting it here myself.
I am also a regulat Coursera student and had managed to watch and hear the HTML5 option videos without problem.
It must be difficult to visualise for people who aren't signed up to Coursera but not unlike YouTube, there are both Flash and HTML5 versions of lecture videos with inline content often in the form of quizzes (or tests, as we call them in the UK!). However, unlike YouTube, it is possible to change settings on the video page.
Just recently (probably aroung the same time Dominique noticed problems) the audio ceased functioning using the HTML option and the in video content and quizzes stopped using the Flash option.
I reported the problem to Coursera but got a pretty unhelpful response.
From Coursera:
Sorry to hear about this, and thank you for letting us know.
We have not had an unusual amount of students reporting issues with the video playback. If its a specific Video, please let us know which one so we can check it. If its the same for all videos on this site, and the problem is slowly getting worse, it sounds like an issue with your browser or cookies and cache.
First, could you please try clearing your browser’s cookies and cache and then let me know if the problem persists? You can find instructions on how to clear various browsers here.
(Link to page which lists the following)
Google Chrome (newest)
Note: Ubuntu users may have to install the chromium-codecs-ffmpeg-extra package to make the videos work in Chromium.
Firefox (23)
Note: The video speed change feature for lecture watching is not yet supported in Firefox.
Safari (newest)
Internet Explorer (9 or newer)
Also, could you kindly tell me what happens if you try this in another browser? You can find a list of Coursera’s supported browsers here.
If those suggestions don’t work, would you mind sending me a screenshot of the problem that you encountered? This will help us better diagnose the issue.
I got the feeling from the response that they hadn't read my message properly as it is not really possible to send a screenshot of either missing quiz or audio.
Anyway, for the record, I had already tried disabling extensions etc. and have cleared cookies and cache as Coursera suggested which has not brought the HTML5 audio back.
Every now and then, I do get an in video quiz using Flash but it's only about one in ten lectures. But the problem is extremely fustrating because it means that I have to load the video lectures multiple times (depending on how many quizzes etc. there are to watch the video in Flash until it reaches a quiz then reload it in HTML5 then reload it in Flash until the next quiz etc. etc.

Using Flash player even though YouTube HTML5 video player is enabled

I'm in YouTube HTML5 video player beta program (http://youtube.com/html5), but even with it being enabled, every time I play a YouTube video it's still using Flash player.

try adding '''&html5=True''' to the end of the URL

HTML5 videos won't play correctly with built-in player

1) When I try to play html5 video, firefox only shows me a few frames, and then screen become grayed and «loading» animation appears. Then it shows me next few frames, and a loading screen again. It continues until the whole video will load.
2) When it finally loads, video and sound are a little bit choppy if the video is in good quality. Other browsers play that videos without any lags or loading screens. Here's the example of one of that videos I couldn't watch normally: https://m.vk.com/video-51189706_170637645
I've looked up at memory indicator, and it showed me that I have at least 200Mbs of free RAM during the loading of these videos. Also every memory limit setting in about:config is set to -1.
I use the latest firefox version from Play Store and own an Asus TF300T tablet (nvidia tegra3 and 1Gb of RAM), so it's certainly not a lack of hardware power.
I also should note that when I watch youtube videos (with firefox, not youtube player, which I've removed), everything is fine — videos are playing and loading at the same time.

I cannot view that video however we are in the process of making some major changes to video playback on Android. Currently these changes are in our Aurora build of Firefox it can be downloaded at https://aurora.mozilla.org if you would like to see if this improves the video playback.
