Multi Language Implementation in ASP.NET Video Starter Kit

  • 01 November 2011

ASP.NET Video Starter Kit 6.0 introduced new approach for managing multiple language, culture user interface to provide ability for user to switch user interface language according to their desired region specific culture or languages settings.

Previous versions of asp.net video starter kit only support multiple culture specific resource files and admin can only set website specific culture via web.config file, so user have no ability to change language, culture with their own will.

Now using asp.net video starter kit 6.0, site administrator can

    • Enable Disable Multi Language User Interface Support
    • Manage all languages through control panel / settings / language management section.
    • Set default language
    • Add or register new language
    • Choose languages from list of country specific languages to appear on front page.
    • Advance options to filter contents based on user culture specific language settings.

If multi language option is enabled from /control panel / settings / configurations / features , list of enabled languages will be shown on front section of website. When user click on any of country flag, whole user interface of website will be translated to selected language or culture.

User language selection will be stored in cookie in order keep preserved user selected language without setting it again.

If advance language specific filter is enabled, then whole website contents will be filters for user based on user selected language or culture settings.

e.g if user choose spanish as language and if content specific option is enabled (control panel / settings / configurations / features) then only spanish related contents will be display on website for selected user.

Under new implementation you can manage unlimited number of regional languages, enable unlimited number of language support for front section.

Site administrator can create new language file by translating any of existing resource file located at /app_globalresources/ section.

We translated all resource files using Google Translator.

ASP.NET Image Handler To Resize and Preview High Quality Images in Real Time

  • 01 November 2011

In this article we will provide information and sample codes for creating image handler file in asp.net, c# or vb.net which can be used to resize image, generate highest quality output and show image preview in real time.

You can directly use image handler in image src path to process and display output on browser.

Such handler file have lots of advantages, e.g

  • Provide ability to resize image in real time and display output on browser.
  • Protect image direct path from access.
  • Add lots of other validation to protect images from anti leeching.

Image handling have some drawbacks

  • Consume resources and performance issues so should be used in cases where its needed. e.g if you provide system for user to prepare image for mobile photo, iphone, psp, high definition, and according to different screen resolutions.

Handler file can be called as

<img src="imagehandler.ashx?filename=abc.jpg"...

Code for generating image handler.

GenerateThumbnail function will be used to generate highest possible quality output based on three paramters,

lcFilename (complete path of source photo), width (output width of photo), height (output height of photo)

Code is shown below

private byte[] GenerateThumbnail(string lcFilename, int Width, int Height)

{
        //Image img = Image.FromStream(fStream);
        //Image thumbnailImage = img.GetThumbnailImage(Width, height),
        //      new Image.GetThumbnailImageAbort(ThumbnailCallback), IntPtr.Zero);

        Bitmap loBMP = null;
        Bitmap bmpOut = null;
        try
        {
            loBMP = new Bitmap(lcFilename);
            ImageFormat loFormat = loBMP.RawFormat;
            Size newSize = new Size();
            newSize.Height = Height;
            newSize.Width = Width;
            bmpOut = new Bitmap(newSize.Width, newSize.Height);
            Graphics canvas = Graphics.FromImage(bmpOut);
            canvas.SmoothingMode = SmoothingMode.AntiAlias;
            canvas.InterpolationMode = InterpolationMode.HighQualityBicubic;
            canvas.PixelOffsetMode = PixelOffsetMode.HighQuality;
            canvas.DrawImage(loBMP, new Rectangle(new Point(0, 0), newSize));
        }
        catch (Exception ex)
        {
           
        }
       
        MemoryStream imageStream = new MemoryStream();
        bmpOut.Save(imageStream, System.Drawing.Imaging.ImageFormat.Jpeg);

        byte[] imageContent = new Byte[imageStream.Length];
        imageStream.Position = 0;
        imageStream.Read(imageContent, 0, (int)imageStream.Length);
        return imageContent;
    }

GenerateThumbnail function to be called in ProcesRequest method to output resized thumb.

if (File.Exists(strPath))

{
     ht = new Hashtable();
     //FileStream fInfo = new FileStream(strPath, FileMode.Open);
     byte[] bFile;
     bFile = GenerateThumbnail(strPath, width, height);
     ht.Add(this.ImageID, bFile);
     //fInfo.Close();
}

Byte[] arrImg = (byte[])ht[this.ImageID];
context.Response.Clear();
context.Response.ContentType = "image/jpeg";
context.Response.BinaryWrite(arrImg);
context.Response.End();

Hope this code will help you generate image handler with highest possible image output.

HTTP Pseudo-Streaming in ASP.NET Video Starter Kit

  • 27 March 2011

Both MP4 and FLV videos can be played back with a mechanism called HTTP \r\nPseudostreaming. This mechanism allows your viewers to seek to not-yet \r\ndownloaded parts of a video. YouTube is an example site that offers this\r\n functionality.

Previously we implement HTTP Pseudostreaming concept based on server \r\nside scripting. Such a script have lots of disadvantages such a script \r\nconsumes a lot of resources, has security implications and can only be \r\nused with FLV files mostly.

Now we encourage user to implement proper HTTP Pseudostreaming through \r\ntheir webserver rather than using any script. HTTP Pseudostreaming does \r\nnot work by default on any webserver. A serverside module is needed to \r\nenable it.

The most popular module is H264 Streaming Module which allow user  to \r\nimplement Http Pseudo streaming for mp4 videos through IIS web server.
How to Setup?

IIS 6 Instructions
IIS 7 Instructions

Once module is enabled, it will stream mp4 videos properly through JW \r\nPlayer as already implemented in ASP.NET Video Starter Kit.

MP4 Encoding & Setting Meta Information via Media Handler Pro

  • 25 October 2010

Here we provide sample code that can help u to use Media Handler Pro component in your asp.net application (c#, vb.net) to

i: Publish any format video to high quality mp4 format using libx264 codec and preset files
ii: Set meta information to mp4 video in order to stream properly on web.

We recommend you to download latest ffmpeg build with presets support from http://ffmpeg.arrozcru.org/autobuilds/

i: Sample Code for MP4 Video using libx264 codec and preset files

private string PresetFilePath = // path of preset file u are doing to use for mp4 encoding. preset files located withing ffmpeg/preset/ folder.
_mhandler.OutputExtension = ".mp4";
_mhandler.OutputFileName = "sample_temp";
_mhandler.VCodec = "libx264";
_mhandler.Parameters = " -bt 240k -fpre " + this.PresetFilePath + "";
_mhandler.Video_Bitrate = 200;
_mhandler.Channel = 2;
_mhandler.Audio_SamplingRate = 48000;
_mhandler.Audio_Bitrate = 192;
_mhandler.FrameRate = 29.97;
info = _mhandler.Process();

The code above will create mp4 video with name 'sample_temp.mp4', In order to stream this video on web you need to add meta information otherwise players will first download complete video and will then play it.
For adding meta information we are using mp4box with Media Handler Pro. U can use the following code to set meta information and make streamable mp4 video from 'sample_temp.mp4' video via mp4box utility.

string MP4BoxPath = // path to mp4box utility in similar way as ffmpeg or preset file path.
_mhandler.MP4BoxPath = MP4BoxPath;
string  _mp4_temp_path = // complete path of output sample_temp.mp4 video
_mhandler.Parameters = "-isma -hint -add " + _mp4_temp_path + "";
_mhandler.FileName = sample_temp.mp4.Replace("_temp.mp4",".mp4"); // replace temp.mp4 with normal mp4 video, remove temp video after creating streamable mp4 video. e.g (sample.mp4)
_mhandler.InputPath = this.OutputPath;
_mhandler.Set_MP4_Buffering();

Set_MP4_Buffering() will create streamable mp4 video (sample.mp4) from (sample_temp.mp4) video.


After creation you can delete sample_temp.mp4 video.

ASP.NET HTML 5, VP8 WEBM Video Encoding using Media Handler Pro.

  • 24 July 2010

Everyone who has visited YouTube.com in the past four years knows that you can embed video in a web page. But prior to HTML5, there was no standards-based way to do this. Every video you've watched on the web has been funneled through a third party plugin (QuickTime, RealPlayer, Flash).

HTML5 defines a standard way to embed video in a web page, using a

<video width="300" height="150"></video>
element.

Support for the <video width="300" height="150"> element is still evolving, which is a polite way of saying it doesn’t work yet. At least, it doesn’t work everywhere. But don’t despair! There are alternatives and fallbacks and options.

 Video Codecs: There are tons of video codecs. The three most relevant codecs are H.264, Theora, and VP8.

H.264 is also known as “MPEG-4 part 10,” a.k.a. “MPEG-4 AVC,” a.k.a. “MPEG-4 Advanced Video Coding.” H.264 was also developed by the MPEG group and standardized in 2003. It aims to provide a single codec for low-bandwidth, low-CPU devices (cell phones); high-bandwidth, high-CPU devices (modern desktop computers); and everything in between. To accomplish this, the H.264 standard is split into “profiles,” which each define a set of optional features that trade complexity for file size. Higher profiles use more optional features, offer better visual quality at smaller file sizes, take longer to encode, and require more CPU power to decode in real-time.

Theora evolved from the VP3 codec and has subsequently been developed by the Xiph.org Foundation. Theora is a royalty-free codec and is not encumbered by any known patents other than the original VP3 patents, which have been licensed royalty-free. Although the standard has been “frozen” since 2004, the Theora project (which includes an open source reference encoder and decoder) only released version 1.0 in November 2008 and version 1.1 in September 2009.

Theora video can be embedded in any container format, although it is most often seen in an Ogg container. All major Linux distributions support Theora out-of-the-box, and Mozilla Firefox 3.5 includes native support for Theora video in an Ogg container. And by “native”, I mean “available on all platforms without platform-specific plugins.” You can also play Theora video on Windows or on Mac OS X after installing Xiph.org’s open source decoder software.

VP8 is another video codec from On2, the same company that originally developed VP3 (later Theora). Technically, it is similar in quality to H.264 Baseline, with lots of potential for future improvements.

In 2010, Google acquired On2 and published the video codec specification and a sample encoder and decoder as open source. As part of this, Google also “opened” all the patents that On2 had filed on VP8, by licensing them royalty-free. (This is the best you can hope for with patents. You can’t actually “release” them or nullify them once they’ve been issued. To make them open source–friendly, you license them royalty-free, and then anyone can use the technologies the patents cover without paying anything or negotiating patent licenses.) As of May 19, 2010, VP8 is a royalty-free, modern codec and is not encumbered by any known patents, other than the patents that On2 (now Google) has already licensed royalty-free.

Encoding VP8 WebM Video using Media Handler Pro.

FFMPEG 0.6 and latest provide support for VP8 Codec via libvpx. You need to download latest win 32 build in order to publish video to WebM format.

ample code for using ASP.NET Media Handler Pro to publish WebM Video

 

VideoInfo info = new VideoInfo();
 _mhandler.FileName = "sample.wmv";
_mhandler.OutputFileName = "sample";
_mhandler.OutputExtension = ".webm";
_mhandler.Force = "webm";
_mhandler.AspectRatio = "4:3";
_mhandler.VCodec = "libvpx";
_mhandler.ACodec = "libvorbis";
_mhandler.Deinterlace = true;
_mhandler.Parameters = "-threads 8 -g 120 -level 216 -profile 0 -qmax 42 -qmin 10 -vb 2M -aq 50 -ac 6";
info = _mhandler.Process();
if (info.ErrorCode > 0)
{
         Response.Write("Error occured while processing webm video");
         return;
}

After publishing you can then play WebM video on HTML 5 player (e.g player provided by http://videojs.com/ Sample way to play WebM Video

<video width="320" height="240"><source src="sample.webm" type='video/webm; codecs="vp8, vorbis"'></video>

Extracting Frames from video and Re encoding images into video using ASP.NET Media Handler Pro.

  • 09 July 2010
You can use the following code through ASP.NET Media Handler Pro
\r\ncomponent to extract all frames of video into jpg images.
\r\nExtracting Frames:
\r\n[quote]
\r\n_mhandler.InputPath = RootPath + "\\\\contents\\\\original";
\r\n_mhandler.OutputPath = RootPath + "\\\\contents\\\\thumbs";
\r\n_mhandler.FileName = "xmen-origins-wolverine.mp4";
\r\n_mhandler.OutputFileName = "sample_";
\r\n_mhandler.OutputExtension = "%010d.jpg";
\r\n_mhandler.Force = "image2";
\r\nVideoInfo info = _mhandler.Process(); [/quote]
\r\nRe Encoding Frames / Images into Video:
\r\nExample below will encode all jpg frames into flash flv video, you can
\r\nencode it in any format.
\r\n[quote]
\r\n_mhandler.InputPath = RootPath + "\\\\contents\\\\thumbs";
\r\n_mhandler.OutputPath = RootPath + "\\\\contents\\\\flv";
\r\n_mhandler.FileName = "sample_.%010d.jpg";
\r\n_mhandler.OutputFileName = "sample_img_vid";
\r\n_mhandler.OutputExtension = "flv";
\r\n_mhandler.Force = "flv";
\r\n// _mhandler.MaxQuality = true;
\r\n_mhandler.Audio_Bitrate = 32;
\r\n_mhandler.Audio_SamplingRate = 22050;
\r\nVideoInfo info = _mhandler.Process(); [/quote]
\r\nIf you receive Error Code 101, you can request updated MHP through our
\r\nsupport email.
