C# Sample Codes
List of c# sample codes below that can help you to use .NET Media Handler Pro in your c# projects for video publishing, thumbs grabbing, extract audio, post watermark on video and perform more media related tasks.
Steps:
Before using c# sample code in your project make sure to
i: download ffmpeg build, unzip and place ffmpeg folder with all files on root of your web application.
ii: copy mediahandlerpro.dll and paste it into /bin/ directory of your web application.
iii: create three directories /contents/original, /contents/output/, /contents/thumbs/ for storing source, output video and generated thumbs.
Sample code and project available with each product bundle.
Example Codes
i: Setup Required Parameters
MediaHandler _mhandler = new MediaHandler();
string RootPath = Server.MapPath(Request.ApplicationPath);
// set ffmpeg path
_mhandler.FFMPEGPath = HttpContext.Current.Server.MapPath("~\\ffmpeg\\ffmpeg.exe");
// set source directory path
_mhandler.InputPath = RootPath + "\\contents\\original";
// set output directory path
_mhandler.OutputPath = RootPath + "\\contents\\output";
// set source filename
_mhandler.FileName = "sample.mp4";
// set output filename
_mhandler.OutputFileName = "sample.3gp";
ii: C# code for posting watermark on video.
// not for posting watermark, ffmpeg must support and exist vhook/watermark.dll // set watermark image directory path _mhandler.WaterMarkPath = RootPath + "\\contents\\watermark"; // set watermark image filename _mhandler.WaterMarkImage = "watermark.gif"; // more detail about posting watermark, click here.
iii: C# code for setting important parameter that can allow user to customize output video.
// set video bitrate, depend on output video format _mhandler.Video_Bitrate = 500; // set audio bitrate, depend on output video format _mhandler.Audio_Bitrate = 64; // set audio sampling rate, depend on output video format _mhandler.Audio_SamplingRate = 22050; // set width of output video _mhandler.Width = 320; // set height of output video _mhandler.Height = 240; // for complete list of parameters, click here , note some parameters may or may not be used for every circumstances so use parameters when required.

// set source filename _mhandlerFileName = "sample.mp4"; // set output filename _mhandler.OutputFileName = "sample.avi"; // set video parameters according to pal-vcd _mhandler.TargetFileType = "pal-vcd"; // start video procesing VideoInfo info = _mhandler.Encode_AVI(); //or VideoInfo info = _mhandler.Process();
v: C# code to generate video from list of images using .NET Media Handler Pro 5.0
// i: All thumbs must be in sequest and in .jpg format e.g a_001.jpg, a_002.jpg, a_003.jpg.... // ii: FileName property below must point actual name of thumb without .jpg and sequence e.g "a_" represent "a_001.jpg...." _mhandlerFileName = "a_"; // set output video filename without any extension _mhandler.OutputFileName = "a"; // set output extension _mhandler.OutputExtension = ".flv"; // set processing VideoInfo info = _mhandler.ImagesToVideo();
vi: C# code for grabbing single or multiple thumbs using .NET Media Handler Pro 5.0
//*************************************************** // Multiple Thumbs: Thumb Mod: Normal // Recommended for multiple thumbs as it support long length videos too //*************************************************** // set thumb start index, e.g sample_ generate sample_001.jpg, sample_002.jpg etc string thumb_start_index = "sample_"; // set source video filename _mhandlerFileName = "sample.mp4"; // set output image format _mhandler.Image_Format = "jpg"; // set image codec (optional) _mhandler.VCodec = "image2"; // set image name, in multiple mode image index required _mhandler.ImageName = thumb_start_index; // set to enable multiple thumb mode _mhandler.Multiple_Thumbs = true; _mhandler.ThumbMode = 0; // set total no of thumb to be generating from video. _mhandler.No_Of_Thumbs = 15; // set start positing / length of video from where thumb grabbing start _mhandler.Thumb_Start_Position = 10; // set width and height of thumb, not it must be multiple of two. _mhandler.Width = 160; _mhandler.Height = 120; // start grabbing thumbs VideoInfo info = _mhandler.Grab_Thumb(); //****************************************************** // Single Thumb //****************************************************** _mhandler.FileName = "sample.mp4"; // set output image name _mhandler.ImageName = "sample.jpg"; // set length in seconds from where you want to grab thumb _mhandler.Frame_Time = "10"; //OR //_mhandlerThumb_Start_Position = 10; _mhandler.Image_Format = "jpg"; _mhandlerVCodec = "image2"; _mhandler.Width = 160; _mhandler.Height = 120; // start grabbing single thumb from video VideoInfo info = _mhandler.Grab_Thumb();

// set list of filenames to be joined with single output. not required that all clips in same format and size
_mhandler.FileNames = new string[] { "sample_01.mp4", "sample_02.mp4" };
// set output video name, without extension recommended.
_mhandler.OutputFileName = "sample_full";
// set output extension
