According to [RFC 4337][1] &#167; 2, `video/mp4` is indeed the correct Content-Type for MPEG-4 video.

Generally, you can find official MIME definitions by searching for the file extension and &quot;IETF&quot; or &quot;RFC&quot;. The RFC (Request for Comments) articles published by the IETF (Internet Engineering Taskforce) define many Internet standards, including MIME types.


  [1]: http://www.rfc-editor.org/rfc/rfc4337.txt

`video/mp4`should be used when you have video content in your file. If there is none, but there is audio, you should use `audio/mp4`. If no audio and no video is used, for instance if the file contains only a subtitle track or a metadata track, the MIME should be `application/mp4`.
Also, as a server, you should try to include the `codecs` or `profiles` parameters as defined in [RFC6381][1], as this will help clients determine if they can play the file, prior to downloading it.

According to &lt;http://help.encoding.com/knowledge-base/article/correct-mime-types-for-serving-video-files/&gt;, the correct mime type for `.mp4` is `video/mp4`

When uploading .mp4 file into Perl script, using CGI.pm I see it as **video/mp** when printing out `Content-type` for the uploaded file.
I hope it will help someone.

I often see people are using Delimiters. I tried myself to find out what are delimiters and what is their purpose. After 20 minutes of googling, I was not able to find an answer which satisfies me. So, my question is now: What are delimiters and when should I use them?

My problem is that I was looking for way to use both **storyboard** and **xib**. But I can&#39;t find proper way to load and show storyboard programmatically. Project was started developing with xib, and now it&#39;s very hard to nest all xib files in storyboard. So I was looking a way to do it in code, like with `alloc, init, push` for viewControllers. In my case I have only one controller in storyboard: `UITableViewController`, which has static cells with some content I want to show. If anyone knows proper way to work both with xib and storyboard without huge refactoring, I will appreciate for any help.

I have two applications as mentioned below:

 1. Admin application  through which I am able to upload a .mp4 file to the server.
 2. I am trying to download the .mp4 using mobile application in iPad.

***

 - The Admin application is made by using asp.net 4.0 and SQL Server, IIS7.
 - The Mobile application is made of asp.net mvc3, jquerymobile, HTML5.

As of now I have added mime type `video/mp4` for .mp4 in IIS7 mime types section.

When I am trying to download the .mp4 file in iPad I am seeing a dark black screen with cross arrow on it. Can anyone please help me to resolve the issue.

Please tell me whether the mime type `video/mp4` for .mp4 is correct.

I&#39;m trying to setup a very basic html5 page that loads a .mp4 video that is 20MB.  It appears that the browser needs to download the entire thing rather than just playing the first part of the video and streaming in the rest.

[This post][1] is the closest thing I&#39;ve found while searching... I tried both Hand Brake and Data Go Round by neither appeared to make a difference: 

Any ideas on how to do this or if it&#39;s possible?

Here is the code I&#39;m using:

&lt;!-- language: lang-html --&gt;

    &lt;video controls=&quot;controls&quot;&gt;
        &lt;source src=&quot;/video.mp4&quot; type=&quot;video/mp4&quot; /&gt;
        Your browser does not support the video tag.
    &lt;/video&gt;

HTML5 - How to stream large .mp4 files?

I&#39;m looking to place a video in an HTML5 page that will begin playing on page-load, and once completed, loop back to the beginning without a break. The video should also **NOT** have any controls associated with it, and either be compatible with all &#39;modern&#39; browsers, or have the option of a polyfill.

Previously I would have done this via `Flash` and `FLVPlayback`, but I would prefer to steer clear of `Flash` in the HTML5 sphere. I&#39;m thinking I could use javascript&#39;s `setTimeout` to create a smooth loop, but what should I use to embed the video itself? Is there something out there that will stream the video the way `FLVPlayback` would?

i am streaming with vlc, and i wan&#39;t to receive the packets, do some reports, and then restream local to a player 

An attempt was made to access a socket in a way forbidden by its access permissions. Why?

Are these both the same? Is H.264 codec of MPEG-4? What if I need to convert flv to high definition H.264 video format? I want make online tv streaming and want to use PHP or Python.

What is the difference between H.264 video and MPEG-4 video?

Is it possible to seek to a particular point in `html5 video` displayed in a web page? I mean ,can I  input a particular time value (say `01:20:30:045` ) and have the player control (slider) move to that point and play from that point onwards?

In older version of mozilla `vlcplugin` I think this is possible by `seek(seconds,is_relative)` method..but I would like to know if this is possible in html video.

**Edit:**

I created the page with video and added javascript as below.When I click on the link ,it displays the time of click..but it doesn&#39;t increment the play location..but continues to play normally.

Shouldn&#39;t the video play location get changed?

html

    &lt;video id=&quot;vid&quot; width=&quot;640&quot; height=&quot;360&quot; controls&gt;

    &lt;/video&gt;
    &lt;a id=&quot;gettime&quot; href=&quot;#&quot;&gt;time&lt;/a&gt;
    &lt;p&gt;
    you clicked at:&lt;span id=&quot;showtime&quot;&gt; &lt;/span&gt; 
    &lt;/p&gt;

    $(document).ready(function(){
        var player = $(&#39;#vid&#39;).get(0);
        $(&#39;#gettime&#39;).click(function(){
                if(player){
                    current_time=player.currentTime;
                    $(&#39;#showtime&#39;).html(current_time+&quot; seconds&quot;);
                    player.currentTime=current_time+10;

seek to a point in html5 video

Does anyone know how to resize the HTML5 video poster such that it fits the exact dimensions of the video itself?

here&#39;s a jsfiddle which shows the problem: http://jsfiddle.net/zPacg/7/

here&#39;s that code:

HTML:

    &lt;video controls width=&quot;100%&quot; height=&quot;100%&quot;  poster=&quot;http://www.wpclipart.com/blanks/buttons/glossy_buttons/glossy_button_blank_orange_rectangle.png&quot;&gt;
      &lt;source src=&quot;http://demo.inwebson.com/html5-video/iceage4.mp4&quot; type=&quot;video/mp4&quot; /&gt;
      &lt;source src=&quot;http://demo.inwebson.com/html5-video/iceage4.ogg&quot; type=&quot;video/ogg&quot; /&gt;
      &lt;source src=&quot;http://demo.inwebson.com/html5-video/iceage4.webm&quot; type=&quot;video/webm&quot; /&gt;
    &lt;/video&gt;​

CSS:

    video{
    border:1px solid red;
    }​

Notice that the orange rectangle doesn&#39;t scale to the red border of the video.

Also, just adding the CSS below doesn&#39;t work either as it rescales the video along with the poster:

    video[poster]{
	height:100%;
	width:100%;
    }

I have a video tag, that I dynamically change its source as I am letting the user to choose from a number of videos from the database. The problem is that when I change the src attribute the video doesn&#39;t load even if I tell it to.

Here is my code:

    $(&quot;#video&quot;).attr(&#39;src&#39;, &#39;my_video_&#39;+value+&#39;.ogg&#39;);
    $(&quot;#video&quot;).load();
	while($(&quot;#video&quot;).readyState !== 4) {
    		console.log(&quot;Video is not ready&quot;);
    };

The code still stays in a infinite loop.

Any help?

**EDIT**:

To Ian Devlin:

    //add an listener on loaded metadata
    v.addEventListener(&#39;loadeddata&#39;, function() {
        console.log(&quot;Loaded the video&#39;s data!&quot;);
        console.log(&quot;Video Source: &quot;+ $(&#39;#video&#39;).attr(&#39;src&#39;));
        console.log(&quot;Video Duration: &quot;+ $(&#39;#video&#39;).duration);
    }, false);

Ok this is the code I have now. The source prints great, but I still can&#39;t get the duration :/

I&#39;m trying to decide which mime type to choose for returning mp3 data (served up by php)

according to this listing of mime types: http://www.webmaster-toolkit.com/mime-types.shtml

    .mp3 	audio/mpeg3
    .mp3 	audio/x-mpeg-3
    .mp3 	video/mpeg
    .mp3 	video/x-mpeg

What are the difference between these, and which should I use?

Does anyone know if there exists a MIME type for Markdown? I guess it is `text/plain`, but is there a more specific one?

What is the MIME type for Markdown?

This is the usual SVG mime type:

    image/svg+xml
And it works great. However, when embedding an SVG font, chrome tells you the mime type is incorrect, obviously because you return a font instead of an image.

Is there any universal mime type? is chrome wrong? is `application/svg+xml` accepted somehow?

I guess this is still a gray area in HTML5 but someone here might know.

Right mime type for SVG images with fonts embedded

I can&#39;t figure out how to force the MIME type `application/json` for a view in Flask. Here is a simple view I&#39;ve thrown together for demonstration purposes:

    @app.route(&quot;/&quot;)
    def testView():
        ret = &#39;{&quot;data&quot;: &quot;JSON string example&quot;}&#39;
        return ret

The JSON string (held in variable `ret`) is gathered from elsewhere (using stdout from another program using [`subprocess`](http://docs.python.org/library/subprocess.html)) so I can&#39;t use [`jsonify`](http://flask.pocoo.org/docs/api/#flask.jsonify) provided with Flask.

I&#39;ve had a look at the [&quot;Returning Json&quot; Documentation][1] and [this](https://stackoverflow.com/questions/7086448/) Stackoverflow question but I haven&#39;t had any luck so far. I&#39;ve been looking around for awhile now &amp; will continue searching but thought I&#39;d ask here just in case anyone has come across this.

Thanks.

The solution:

    @app.route(&quot;/&quot;)
    def testView():
        ret = &#39;{&quot;data&quot;: &quot;JSON string example&quot;}&#39;

        resp = Response(response=ret,
                        status=200,
                        mimetype=&quot;application/json&quot;)

        return resp

Forcing application/json MIME type in a view (Flask)

For certain resources, my RESTful server only accepts `PUT` and `POST` requests with JSON objects as the content body, thus requiring a `Content-Type` of `application/json` instead of `application/x-www-form-urlencoded` or `multipart/form-data` or anything else.

Malformed JSON (or lack thereof) returns a `400` with the error message taken directly from the exception raised by the JSON parser, for debugging purposes.

Which HTTP error code means that the client sent a request with an unacceptable `Content-Type`, even if the server could technically parse the request content?
