I found that the following accept string will add mp4 and m4v to the list of file types that safari will accept:

    accept=&quot;video/mp4,video/x-m4v,video/*&quot;

I&#39;m not sure what the mime type is for webm videos but if you can look that up you should be able to tack it on to the accept string. The trick is to specify the mime type, just using a file extension won&#39;t work.

You can take a look at webkit source code [~/Source/WebCore/platform/MIMETypeRegistry.cpp](https://trac.webkit.org/browser/trunk/Source/WebCore/platform/MIMETypeRegistry.cpp). 

These types are customized by Apple for Safari, and may not be working on other browsers.


I have four table headers:

    $scope.headers = [&quot;Header1&quot;, &quot;Header2&quot;, &quot;Header3&quot;, &quot;Header4&quot;];

And I want to be able to sort my table by clicking on the header.

So if my table looks like this

    H1 | H2 | H3 | H4
    A    H    D   etc....
    B    G    C
    C    F    B
    D    E    A

and I click on

    H2

my table now looks like this:

    H1 | H2 | H3 | H4
    D    E    A   etc....
    C    F    B
    B    G    C
    A    H    D

That is, the content of each column never changes, but by clicking on the header I want to order the columns by, the rows will reorder themselves.

The content of my table is created by a database call done with [Mojolicious][1] and is returned to the browser with

    $scope.results = angular.fromJson(data); // This works for me so far

The rest of the code I have cobbled together looks something like this:

    &lt;table class= &quot;table table-striped table-hover&quot;&gt;
        &lt;th ng-repeat= &quot;header in headers&quot;&gt;
            &lt;a&gt; {{headers[$index]}} &lt;/a&gt;
        &lt;/th&gt;
        &lt;tr ng-repeat &quot;result in results&quot;&gt;
            &lt;td&gt; {{results.h1}} &lt;/td&gt;
            &lt;td&gt; {{results.h2}} &lt;/td&gt;
            &lt;td&gt; {{results.h3}} &lt;/td&gt;
            &lt;td&gt; {{results.h4}} &lt;/td&gt;
        &lt;/tr&gt;
    &lt;/table&gt;

How do I order the columns from this point, just by clicking on the header at the top of the table?

I am using an HTML file input like this: 

    &lt;input type=&quot;file&quot; accept=&quot;video/*&quot;&gt; 

to allow my users to upload videos to my site. This works as expected in all modern browsers (only permitting the user to select video files) except Safari.


From what I can tell Safari seems to interpret the `accept=&quot;video/*&quot;` attribute as `accept=&quot;*.mov&quot;` ignoring most, if not all, other video formats / extensions (webm, m4v, etc).

Any suggestions on how to get the select dialog to allow only common video filetypes (not just .mov&#39;s) in Safari?

I want to capture a frame from video every 5 seconds. 

This is my JavaScript code:

    video.addEventListener(&#39;loadeddata&#39;, function() {
		var duration = video.duration;
		var i = 0;
			
		var interval = setInterval(function() {
			video.currentTime = i;
			generateThumbnail(i);
			i = i+5;
			if (i &gt; duration) clearInterval(interval);
		}, 300);
    });

	function generateThumbnail(i) {		
	    //generate thumbnail URL data
		var context = thecanvas.getContext(&#39;2d&#39;);
		context.drawImage(video, 0, 0, 220, 150);
		var dataURL = thecanvas.toDataURL();

		//create img
		var img = document.createElement(&#39;img&#39;);
		img.setAttribute(&#39;src&#39;, dataURL);
			
		//append img in container div
		document.getElementById(&#39;thumbnailContainer&#39;).appendChild(img);
	}

The problem I have is the 1st two images generated are the same and the duration-5 second image is not generated. I found out that the thumbnail is generated before the video frame of the specific time is displayed in `&lt; video&gt;` tag. 

For example, when `video.currentTime = 5`, image of frame 0s is generated. Then the video frame jump to time 5s. So when `video.currentTime = 10`, image of frame 5s is generated.

Capture frames from video with HTML5 and JavaScript

I was watching a youtube video and I decided to investigate some parts of its video player.  I noticed that unlike most HTML5 video I have seen, Youtube&#39;s video player does not do a normal video source and instead utilizes a blob url as the source.  

Previously I have tested HTML5 videos and I found that the server starts streaming the whole video from  the start and buffers in the background the complete rest of the video.  This means that if your video is 300 megs, all 300 megs will be downloaded.  If you seek to the middle, it will start downloading from the seek position all the way to the end.  

Youtube does not work this way (at least in chrome).  Instead it manages to control buffering so it only buffers a certain amount while paused. It also seems to only buffer the relevant pieces, so if you skip around it will make sure not to buffer pieces that are unlikely to be watched.

In my attempts to investigate how this worked, I noticed the video src tag has a value of `blob:http%3A//www.youtube.com/ee625eee-2802-49b2-a13f-eb374d551d54`, which pointed me to &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/Blob&quot;&gt;blobs&lt;/a&gt;, which then led me to &lt;a href=&quot;https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Sending_and_Receiving_Binary_Data&quot;&gt;typed arrays&lt;/a&gt;.  Using those two resources I am able to load a mp4 video into a blob and display it in a HTML5 video tag.

However, what I am now stuck on is how Youtube deals with the pieces.  Looking at the network traffic it appears to sends requests to `http://r6---sn-p5q7ynee.c.youtube.com/videoplayback` which returns binary video data back in chunks of 1.1mb.  It also seems worth noting that most normal requests due to HTML5 video requests seem to receive a 206 response code back while it streams, yet youtube&#39;s playvideo calls get a 200 back.

I tried to attempt to only load a range of bytes (via setting the `Range` http header) which unfortunately failed (I&#39;m assuming because there was no meta-data for the video coming with the video).  

At this point I&#39;m stuck on figuring out how Youtube accomplishes this.  I came up with several ideas though none of which I am completely sold on:

1) Youtube is sending down self contained video and audio chunks with each `/videoplayback` call.  This seems like a pretty heavy burden on the upload side and it seems like it would be difficult to stitch these together to make it appear like it&#39;s one seemless video.  Also, the video tag seems to think it&#39;s one full video, judging from calling `$(&#39;video&#39;).duration` and `$(&#39;video&#39;).currentTime`, which leads me to believe that the video tag thinks it&#39;s a single video file.  Finally, the vidoe src tag never changes which makes me believe it is working with a singular blob and not switching out blobs.

2) Youtube constructs an empty blob pre-sized to the full video array and updates the blob with pieces as it downloads it.  It would then make sure the user has not gotten too close to the last downloaded piece (to prevent the user from entering an undownloaded section of the blob).  The problem that I see with this that I don&#39;t see any way to dynamically update a blob through javascript (although maybe I&#39;m just having trouble googling for it)

3) Youtube downloads the meta data and then starts constructing the blob in order by appending the video pieces as it downloads them.  The problem I see with this method is I don&#39;t understand how it would handle seeks in post-buffered territory.

Maybe I&quot;m just missing an obvious answer that&#39;s right in front of me.  Anyone have any ideas?


&lt;hr&gt;
&lt;b&gt;edit:&lt;b&gt; I just thought of a fourth option.  Another idea is they might use the file API to write the binary chunks to a file and use that file to stream off of.  The file API seems to have the ability to seek to specific positions, therefore allowing you to fill a video with empty bytes and fill them in as they are received.  This would definitely accommodate video seeking as well.

How does Youtube&#39;s HTML5 video player control buffering?

Videos on most sites make use of progressive downloading, which means that the video is downloaded to my computer, and easy to trace. There are lots of extensions out there to do this, and even in the dev-tools this is easily done.

On certain websites videos are streamed. which means that we do no just download 1 file, we download lots of small packages. In the dev-tools these packages can be traced. The website I&#39;m interested in is: http://www.rtlxl.nl/#!/goede-tijden-slechte-tijden-10821/c8e2bff7-5a5c-45cb-be2b-4b3b3e866ffb.

-The packages have a .TS extension.

-Packages can be saved by copying the url of the request

-I can not play these files.

I must have done something wrong, or I&#39;m missing something. I want to know what I am doing wrong. I want to create a chrome extension for personal use which captures the urls of all the packages. when I have all the urls I want to pass them on to a php scripts which downloads them and uses ffmpeg to paste them into a mp4 file.

Please help me get the packages.

I am attempting to create a thumbnail preview from a video file (mp4,3gp) from a form `input type=&#39;file&#39;`.  Many have said that this can be done server side only.  I find this hard to believe since I just recently came across this Fiddle using HTML5 Canvas and Javascript.

[**Thumbnail Fiddle**][1]


  [1]: http://jsfiddle.net/vphyr/

The only problem is this requires the video to be present and the user to click play before they click a button to capture the thumbnail.  I am wondering if there is a way to get the same results without the player being present and user clicking the button.  For example: User click on file upload and selects video file and then thumbnail is generated. Any help/thoughts are welcome!

    data = f.read()
    jsonObj = json.loads(data)

HTML5 Video tag not working in Safari , iPhone and iPad

I&#39;ve build a web page that let&#39;s you select a page name from a drop down list and then transfers the browser to that page.  The code that does the transfer is

    if (url){
        window.open(url, &#39;_blank&#39;);
    } 

where &quot;url&quot; is the page selected.

A console log just before the window.open line prints something like:

        executing: window.open(http://www.mywebsite.com/44/threats.html, &#39;_blank&#39;)

and then the browsers opens the page in a new tab.

This works fine on Windows 7 for all the browsers, including Safari.  

On an iMac it works for Firefox but not for Safari. 
 
Does anyone know why iMac/Safari won&#39;t do  this?

On my last website, the text is perfect naturally on chrome and firefox without touching font-smoothing or anything else.   
But on Mac / Safari 7 the text appears well then turns immediately thinner (too much thinner / not nice to read).
![enter image description here][1]
![enter image description here][2]

After doing some research [cf http://www.usabilitypost.com/2012/11/05/stop-fixing-font-smoothing/]  
and some tests playing with 

    -webkit-font-smoothing    

It looks like Safari display the text first with :

    -webkit-font-smoothing: subpixel-antialiased;

Then just after you got the flickering effect, when it is turning font to :

    -webkit-font-smoothing: antialiased;



So it seems to me that I had no choice but to force 

    -webkit-font-smoothing: subpixel-antialiased;

to make my website consistent on all browsers.  
I am using font-face Avenir Std Roman.

Some explanations to that Safari problem ?
Any better solutions ?
Could my font be part of the problem ?

Thanks.

Font weight turns lighter on Mac/Safari

You might already know, that Safari has a nasty autofill bug where it fills email, username and password fields no matter if you set `autocomplete=&quot;off&quot;` or not.

Here&#39;s a basic form:

    &lt;form action=&quot;/&quot; method=&quot;post&quot;&gt;
        &lt;p&gt;
            &lt;label&gt;E-mail&lt;/label&gt;
            &lt;input type=&quot;text&quot; name=&quot;email&quot; value=&quot;&quot; /&gt;
        &lt;/p&gt;
        &lt;p&gt;
            &lt;label&gt;Password&lt;/label&gt;
            &lt;input type=&quot;password&quot; name=&quot;password&quot; value=&quot;&quot; /&gt;
        &lt;/p&gt;
    &lt;/form&gt;

...Safari autofills those fields on page load like it should, job well done!

If you put `autocomplete=&quot;off&quot;` to the fields and/or the form element, Safari still autofills those fields:

    &lt;form action=&quot;/&quot; method=&quot;post&quot; autocomplete=&quot;off&quot;&gt;
        &lt;p&gt;
            &lt;label&gt;E-mail&lt;/label&gt;
            &lt;input type=&quot;text&quot; name=&quot;email&quot; value=&quot;&quot; autocomplete=&quot;off&quot; /&gt;
        &lt;/p&gt;
        &lt;p&gt;
            &lt;label&gt;Password&lt;/label&gt;
            &lt;input type=&quot;password&quot; name=&quot;password&quot; value=&quot;&quot; autocomplete=&quot;off&quot; /&gt;
        &lt;/p&gt;
    &lt;/form&gt;

Even this doesn&#39;t work:

    &lt;form action=&quot;/&quot; method=&quot;post&quot; autocomplete=&quot;off&quot;&gt;
        &lt;p&gt;
            &lt;label&gt;E-mail&lt;/label&gt;
            &lt;input type=&quot;text&quot; name=&quot;secretfield1&quot; value=&quot;&quot; autocomplete=&quot;off&quot;/&gt;
        &lt;/p&gt;
        &lt;p&gt;
            &lt;label&gt;Password&lt;/label&gt;
            &lt;input type=&quot;password&quot; name=&quot;secretfield2&quot; value=&quot;&quot; autocomplete=&quot;off&quot; /&gt;
        &lt;/p&gt;
    &lt;/form&gt;

...since Safari looks up those `&lt;label&gt;` elements if they contain words &quot;E-mail&quot;, &quot;Password&quot; etc. and goes ahead with the autofill.

Aaaahhhhha!, I thought, and tried this:

    &lt;form action=&quot;/&quot; method=&quot;post&quot; autocomplete=&quot;off&quot;&gt;
        &lt;p&gt;
            &lt;label&gt;%REPLACE_EMAIL_TITLE%&lt;/label&gt;
            &lt;input type=&quot;text&quot; name=&quot;%REPLACE_EMAIL_NAME%&quot; value=&quot;&quot; autocomplete=&quot;off&quot;/&gt;
        &lt;/p&gt;
        &lt;p&gt;
            &lt;label&gt;%REPLACE_PASSWORD_TITLE%&lt;/label&gt;
            &lt;input type=&quot;password&quot; name=&quot;%REPLACE_PASSWORD_NAME%&quot; value=&quot;&quot; autocomplete=&quot;off&quot; /&gt;
        &lt;/p&gt;
    &lt;/form&gt;

...and replace %TAGS% with the real names using JavaScript. Safari autofill kicks in. No matter if you set a 10 second timeout on the replacement.

So, is this really the only option?

    &lt;form action=&quot;/&quot; method=&quot;post&quot; autocomplete=&quot;off&quot;&gt;
        &lt;p&gt;
            &lt;label&gt;That electronic postal address we all use, but can&#39;t write the title here because Safari fills this with YOUR information if you have autofill turned on&lt;/label&gt;
            &lt;input type=&quot;text&quot; name=&quot;someelectronicpostaladdress&quot; value=&quot;&quot; autocomplete=&quot;off&quot;/&gt;
        &lt;/p&gt;
        &lt;p&gt;
            &lt;label&gt;A set of characters, letters, numbers and special characters that is so secret that only you or the user you are changing it for knows, but can&#39;t write the title here because Safari sucks&lt;/label&gt;
            &lt;input type=&quot;password&quot; name=&quot;setofseeecretcharacters&quot; value=&quot;&quot; autocomplete=&quot;off&quot; /&gt;
        &lt;/p&gt;
    &lt;/form&gt;

I hope not?

UPDATE: [@skithund pointed out in Twitter][1], that [Safari is getting a 4.0.3 update][2], which mentions &quot;Login AutoFill&quot;. Does anyone know if that update is going to fix this?

Disabling Safari autofill on usernames and passwords

In Safari 7, the main html file with a manifest is loadable when offline, but none of the external resources are loaded, even if they&#39;re listed in the manifest file as cached. Safari&#39;s resource pane lists the files as in the application cache, but it will not load them. I&#39;ve tried an extremely simple test, checked MIME type of the manifest file, renamed the manifest file, and tried other demos. Here&#39;s an example that works fine on Chrome, but on Safari it will not load the sticky image when offline: http://htmlfive.appspot.com/static/stickies.html

This is the same problem described in https://stackoverflow.com/questions/20655771/appcache-misbehaving-in-safari-firefox, but I think that question doesn&#39;t make the problem as clear, and I wanted to provide a question with a concrete demo. Is there a work-around, or does Safari 7 totally not support application cache beyond the primary html file? Thanks!

Given a datum containing multiple data elements, such as an object or array, is it possible to set multiple attributes on a selection with a single value function?

E.g. something like:

    var data = [{ &#39;x&#39;: 10, &#39;y&#39;: 20, &#39;r&#39;: 5 }];
    d3.select(&#39;body&#39;).append(&#39;svg&#39;).selectAll(&#39;circle&#39;)
        .data(data)
        .enter().append(&#39;circle&#39;)
        .attr(&#39;cx cy r&#39;, function (d) {
            return [d.x, d.y, d.r];
        });

instead of:

    var data = [{ &#39;x&#39;: 10, &#39;y&#39;: 20, &#39;r&#39;: 5 }];
    d3.select(&#39;body&#39;).append(&#39;svg&#39;).selectAll(&#39;circle&#39;)
        .data(data)
        .enter().append(&#39;circle&#39;)
        .attr(&#39;cx&#39;, function (d) {
            return d.x;
        });
        .attr(&#39;cy&#39;, function (d) {
            return d.y;
        });
        .attr(&#39;r&#39;, function (d) {
            return d.r;
        });


How to set multiple attributes with one value function?

Here is my code

    N = namedtuple(&quot;N&quot;, [&#39;ind&#39;, &#39;set&#39;, &#39;v&#39;])
    def solve()
        items=[]
        stack=[]
        R = set(range(0,8))
        for i in range(0,8):
            items.append(N(i,R,8))		
            stack.append(N(0,R-set(range(0,1)),i))
        while(len(stack)&gt;0): 
            node = stack.pop()
            print node
            print items[node.ind]	
            items[node.ind].v = node.v

In the last line I cant set the `items[node.ind].v` value to `node.v` as I want, and am getting the error 

    &quot;AttributeError: can&#39;t set attribute&quot;

I don&#39;t know what&#39;s wrong but it must be something based on syntax as using statements like `node.v+=1` is also showing same error. I&#39;m new to Python, so please suggest a way to make the above change possible.

I was going through the source code of a website and found this piece of code.

    &lt;meta name=&quot;viewport&quot; content=&quot;width=device-width, initial-scale=1.0, user-scalable=1.0, minimum-scale=1.0, maximum-scale=1.0&quot;&gt;

I want to know what this initial scale, user-scalable, minimum-scale, maximum-scale are and what does those values mean? And also tell me what all values they accepts.

What is initial scale, user-scalable, minimum-scale, maximum-scale attribute in meta tag?

I&#39;m working on a H.264 Decoder and I&#39;m wondering where to find the SPS and PPS. My reference literature tells me that those are NAL Units encoded in the H.264-Stream, but when I look into an example-MP4-File with IsoViewer, it says that the SPS and PPS are in the avcC Box. 

How exactly does this work? How does it look for .mkv files or other H.264 containers?

I tried to find a good solution on the bootstrap site but I didn&#39;t get an answer to this yet. I think I can&#39;t be the only one struggling with this, but I couldn&#39;t find anything that helped me.

I&#39;m trying to embed an mp4-video on my website. The problem is, that if I use an iframe-tag I can&#39;t use autoplay and loop. 
Because of that I would like to solve it with a video tag (or something else that supports autoplay and loop). After that I tried to make my video responsive with an object-tag but this didn&#39;t work. Even though I let it in my code (to show you) which you can see below:

    &lt;div align=&quot;center&quot;&gt;
       &lt;object class=&quot;embed-responsive-item&quot;&gt;
         &lt;video autoplay loop &gt;
		   &lt;source src=&quot;file.mp4&quot; /&gt;
         &lt;/video&gt;
       &lt;/object&gt;
     &lt;/div&gt;

I hope anyone of you can help me fix this.
