C# Sample Codes and Examples
Here you can find some sample codes and example of how to use c# to encode videos from any video format to FLV video format and others. You can use Media Handler Pro in your c# applications to encode videos to different formats and perform other processings including posting wartermark on videos, encode / convert videos to flv format, grab single or multiple thumbnails from video, extract audio from videos to generate mp3 audio files and others.
Please view some sample c# codes and examples below. If you have to know more about it, please contact us.
Sample Code
//After uploading video
//Create object of Media_handler class
Media_handler _mediahandler=new Media_handler();
// Set root path of web application
string rootpath =Server.MapPath(Request.ApplicationPath);
//Set ffmpeg.exe path
string _ffmpegpath =HttpContext.Current.Server.MapPath("~\\ffmpeg\\ffmpeg.exe");
//Set path of source video directory, path where original video exist //'
string inputpath = rootpath + "\\Images\\Default";
//Set path of destination video directory, path where generated, encoded video will be store
string outputpath = rootpath + "\\Images\\FLV";
// Call Convert_Media function of Media_handler class to convert selected video to flv //format
// Note sample available here written according to full version of component, free version //slightly have different return string than full version. please view product documentation //for more help.
//Method No 1
string fullstring = _mediahandler.Convert_Media(filename, _ffmpegpath, InputPath, OutputPath, 320, 240, 360, 25, 32, 22050, "0", true);
//this function return flv video name in free version and many outputs in the form of //string 'separated by comma in full version. e.g str = "FileName:04db71f6-a.flv,Duration: //00:00:29.8, 'start: 0.000000,size: 176x144,SamplingRate: 44100 Hz"
//Method No 2
string fullstring = _mediahandler.Convert_Media(filename, _ffmpegpath, InputPath, OutputPath, "320x240", 360, 25, 32, 22050, "0", true);
// Method No 3
string fullstring = _mediahandler.Convert_Media(filename, _ffmpegpath, InputPath, OutputPath, "320x240", 32, 44100, "0", true); Recommended for highest quality flv video
// Method No 4
string fullstring = _mediahandler.Convert_Media(filename, _ffmpegpath, InputPath, OutputPath, 32, 44100, "0", true); Recommended for highest quality flv video
// Method No 5
string fullstring = _mediahandler.Convert_Media(filename, _ffmpegpath, InputPath, OutputPath, 360, 32, 22050, "0", true);
Sample Code
//After converting video to flv format or video is already in flv format
//Create object of Media_handler class
Media_handler _mediahandler=new Media_handler();
// Set root path of web application
string rootpath =Server.MapPath(Request.ApplicationPath);
// Set flvtool path
string _flvtoolpath =HttpContext.Current.Server.MapPath("~\\flvtool\\flvtool2.exe");
// Set path of source video directory, path where original video exist //'
string outputpath = rootpath + "\\Images\\FLV";
//Call Set_Buffering function to set meta-information to flv video
_mediahandler.Set_Buffering(outfile, _flvtoolpath, Path);
Sample Code
//After uploading video and successfully converting to flv format
//Create object of Media_handler class
Media_handler _mediahandler=new Media_handler();
// Set root path of web application
string RootPath = Server.MapPath(Request.ApplicationPath)
//Set ffmpeg.exe path

// Set path of source video directory, path where original video exist //'
string inputpath = rootpath + "\\Images\\Default";
//Set path of destination video directory, path where generated, encoded video will be store
string outputpath = rootpath + "\\Images\\FLV";
//Set path of image directory, path where generated thumbnail image will be store
string thumbpath = rootpath + "\\Images\\Thumbs";
// Call Grab_Image function of Media_handler class to capture thumbnail from video
string image_name = _mediahandler.Grab_Image(outfile, _ffmpegpath, OutputPath, ThumbPath, "00:00:03", "png", 110, 90);
// Where image_name is the name of thumbnail that is captured and stored in thumbpath directory.
//For capturing multiple thumbnails in a sequence use.
string multiplethubms = _mediahandler.Grab_Multiple_Image(outfile, _ffmpegpath, InputPath, OutputPath, 4, "00:00:02", "jpg", 110, 90);
//where 4 shows number of frames or thumbnails to be capture.
Sample Code
//Create object of Media_handler class
