It&#39;s almost certainly going to stay at 11 characters. The individual characters come from a set of 64 possibilities (A-Za-z0-9_-).

64^11 is somewhat more than 2^64. (10 characters would not be enough.) So basically each youtube ID is actually a 64bit number. And I quite doubt they will ever run out of those.

If you want to save space in your database you could theoretically convert the IDs to 64bit numbers then convert them back later. But you would need to know how youtube does the conversion so it&#39;s not practical. (Since 64^11 is more than 2^64 you can&#39;t store all possibilities, so you need to know which ones are impossible and google doesn&#39;t say.)

It takes 66 bits to store all possibilities. So you could actually store a 64bit number plus a 2 bit number and save some space that way. Or more practically store 9 8bit values - you would save only 2 bytes per record though over storing it as text, so it&#39;s probably not worth it.

The video ID of a YouTube video is currently 11 characters in length. Here are a few links that I found:

http://drupal.org/node/175482

http://snipplr.com/view/19232/retrieve-youtube-video-id-from-a-yt-url/

However, while this is the current standard, there is no official stance on how long the video ID can be.  Here is a posting to that effect from a team member at YouTube:

http://osdir.com/ml/youtube-api-gdata/2009-10/msg00237.html

I&#39;ve found this video id `jCJ7pHxKlEM1`[youtube][1] that has a video id of 12 characters.

Can a WebWorker access the localStorage?

If not why not? Is it problematic from a security stand point?


Accessing localStorage from a webWorker

I&#39;m developing an application that displays youtube videos. I want to store the video id&#39;s in a database, but because there are going to be a lot of videos, I want to minimize the required space, so does anyone know the maximum length of a video id on youtube?

What&#39;s the maximum length of a youtube video id?

I just came home from my exam in network-programming, and one of the question they asked us was **&quot;If you are going to stream video, would you use TCP or UDP? Give an explanation for both stored video and live video-streams&quot;**. To this question they simply expected a short answer of TCP for stored video and UDP for live video, but I thought about this on my way home, and is it necessarily better to use UDP for streaming live video? I mean, if you have the bandwidth for it, and say you are streaming a soccer match, or concert for that matter, do you really need to use UDP?

Lets say that while you are streaming this concert or whatever using TCP you start losing packets (something bad happened in some network between you and the sender), and for a whole minute you don&#39;t get any packets. The video-stream will pause, and after the minute is gone packets start to get through again (IP found a new route for you). What would then happen is that TCP would retransmit the minute you lost and continue sending you the live stream. As an assumption the bandwidth is higher than the bit-rate on the stream, and the ping is not too high, so in a short amount of time, the one minute you lost will act as a buffer for the stream for you, that way, if packet-loss happens again, you won&#39;t notice.

Now, I can think of some appliances where this wouldn&#39;t be a good idea, like for instance video-conferences, where you **need** to always be at the end of the stream, because delay during a video-chat is just horrible, but during a soccer-match, or a concert what does it matter if you are a single minute behind the stream? Plus, you are guaranteed that you get all the data and it would be better to save for later viewing when it&#39;s coming in without any errors.

So this brings me to my question. Are there any drawbacks that I don&#39;t know of about using TCP for live-streaming? Or should it really be, that if you have the bandwidth for it you should go for TCP given that it is &quot;nicer&quot; to the network (flow-control)?

TCP vs UDP on video stream

I&#39;ve found how to pause and play the video using jquery&lt;br /&gt;

    $(&quot;video&quot;).get(0).play();
    $(&quot;video&quot;).get(0).pause();

But I can&#39;t find the mute button, if there isn&#39;t a jquery solution, I&#39;m fine with just an onclick js solution. I need it asap.&lt;br/&gt;&lt;br/&gt;Also is there a way to fix the mute delay? I want it to mute/unmute the sound as soon as the button is clicked.


How to mute an html5 video player using jQuery

I&#39;m trying to use `Gstreamer`&#39;s &lt;a href=&quot;http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-editing-services/html/index.html&quot;&gt;GStreamer Editing Services&lt;/a&gt; to `concatenate` 2 videos, and to have a `transition` between the two.

This command, which joins 2 segments of the videos together without a transition, works fine:

    ges-launch-0.10 vshort01.mov 0 5 vshort02.mov 5 5 -r -o file:///tmp/foo.mov

Here is the output from it:

    $ ges-launch-0.10 vshort01.mov 0 5 vshort02.mov 5 5 -r -o file:///tmp/foo.mov
    save_path: (null)
    load_path: (null)
    Adding file:///home/rory/vshort01.mov inpoint:0:00:00.000000000 duration:0:00:05.000000000
    Adding file:///home/rory/vshort02.mov inpoint:0:00:05.000000000 duration:0:00:05.000000000
    Done

If I try to have a short `transition` between the 2 videos with this command, it just hangs.

    ges-launch-0.10 vshort01.mov 0 5 +transition crossfade 2 vshort02.mov 5 5 -r -o file:///tmp/foo.mov

The output, I get is this:

    save_path: (null)
    load_path: (null)
    Adding file:///home/rory/vshort01.mov inpoint:0:00:00.000000000 duration:0:00:05.000000000
    Adding &lt;transition:crossfade&gt; duration 0:00:02.000000000
    Adding file:///home/rory/vshort02.mov inpoint:0:00:05.000000000 duration:0:00:05.000000000

And there it hangs. The file ``/tmp/foo.mov`` stays at 0 bytes, with no CPU activity.

&gt; I am using package ``ges0.10-tools`` version 0.10.1-1 on ubuntu 11.04 natty. I have tried a freshly built version of gst-editing-services
&gt; from a git clone today ``c2668d058501513b734c8a8013a5e78c817712bb``

I tried without the ``-r -o …`` options (i.e. telling `ges-launch` to display the video, not render it to a file), and the same problems occurred. With the ``+transitition``, the window opens (to show the video) showing the first frame of the first video. But the video doesn&#39;t play, and there is no CPU usage etc.

How do I get it to make a file and transition between them?

GStreamer Editing Services freezes when transitions are added

I want to write a little iOS video client and have to use HTTP Live Streaming. The videos come from a Wowza Media Server which supports HTTP Live Streaming, so the server-side implementation is not my problem.
I have already watch the WWDC videos and read the Apple documentation about HTTP Live Streaming. 

But there is nowhere explained how to play back the videos on an iOS device. In a WWDC-talk was mentioned that there are 3 possibilities to display the videos:

 - UIWebView 
 - MPMoviePlayerController
 - AVPlayerItem

Which one is the best?

And how can I read out the video-URL&#39;s from a HTML-Page like these, which become provided by the server?

    &lt;html&gt;

Implementation of HTTP Live Streaming in iOS

I&#39;ve looked through a couple of questions to find out if an HTML5 element is playing, but can&#39;t find the answer. I&#39;ve looked at the W3 documentation and it has an event named &quot;playing&quot; but I can&#39;t seem to get it to work.

This is my current code:

    var stream = document.getElementsByTagName(&#39;video&#39;);
    
    function pauseStream() {
      if (stream.playing) {
        for (var i = 0; i &lt; stream.length; i++) {
          stream[i].pause();
          $(&quot;body &gt; header&quot;).addClass(&quot;paused_note&quot;);
          $(&quot;.paused_note&quot;).text(&quot;Stream Paused&quot;);
          $(&#39;.paused_note&#39;).css(&quot;opacity&quot;, &quot;1&quot;);
        }
      }
    }

Detect if HTML5 Video element is playing

I&#39;m trying to start playing an embedded youtube video by clicking an image. The idea is to have an image on top of a video, and when the image is clicked it fades out and starts playing the video.

I&#39;m using jquery to fade the image, and was hoping to find a way to play or click the video using jquery as well. 

The fading is working fine, but I can&#39;t figure out how to trigger the video to play. 
I got it to work on a couple of browsers by setting the video to autoplay and hide it, and then fade in the video when the image was clicked. On most browsers the video would autoplay when faded in, but in chrome it started to autoplay even when it was hidden. It didn&#39;t work well in iOS either.

Since I&#39;m pretty new at this, I&#39;m not even sure if I&#39;m writing it 100% correct, but I&#39;ve tried something like this without success:

         $(&#39;#IMAGE&#39;).click(function() { $(&#39;#VIDEO&#39;).play(); });

So, how would I go about to make the video play on an image click? 
Is there a way to play the video when the image is clicked, just using jquery?

Thank you in advance.


start/play embedded (iframe) youtube-video on click of an image

We have a Wicket app with a page that includes an embedded Youtube video. The video embeds and plays fine, but apparently it causes the rest of the page to not render- it seems that the DOM elements coming *after* the embed simply don&#39;t show up on the page, despite being in the markup.

Looking at the error console in Chrome reveals:

&gt; Unsafe JavaScript attempt to access
&gt; frame with URL
&gt; http://example.com/detail/COMMUNICATION/search/com-sonyericsson-hanashi
&gt; from frame with URL
&gt; http://www.youtube.com/embed/eJY7_De5opI?enablejsapi=1&amp;autohide=1&amp;showinfo=1.
&gt; Domains, protocols and ports must
&gt; match.

I&#39;ve googled this a fair amount, and people seem to be saying that [it&#39;s innocuous][1] and to ignore it. That just seems wrong, and in our case it actually breaks the page. 

If we change our app so that the video is embedded dynamically via an ajax callback (user clicks a Wicket AjaxLink) we still get the error in the console, but at least the page renders fully. Unfortunately this won&#39;t work for us, as we need the video to be loaded by default when the user first hits the page.


**Edit**: I should add that although the error message was taken from the Chrome console, the bug seems to affect every browser I&#39;ve tried: Chrome, Safari and Firefox.

Youtube embed: Unsafe JavaScript attempt to access frame

I am trying to embed the new iframe version of a YouTube video and get it to auto play. 

As far as I can tell, there is no way of doing this by amending flags to the URL. Is there a way to do it by using JavaScript &amp; the API?

How to embed an autoplaying YouTube video in an iframe?

I am working on a site that has a ton of embedded youtube videos, the client wants to show a popup whenever a video stops splaying.

I looked at the youtube api and there seems to be a way to detect when a video ends:

http://code.google.com/apis/youtube/js_api_reference.html

but I can&#39;t embed the videos like they mentioned on that page since the videos are all already on the site (thousands that have been added manually by pasting embed code).

Is there a way to detect the ending of these videos without changing any of the existing videos (using javascript)?
