Convert video to FLV format:

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);

Set Meta-Information for FLV Videos:

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);

Grab image thumbnail from video:

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

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";

//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.

// 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\\MPEG";

//Call Convert_Media_To_MPEG function of Media_handler class to convert video to mpg format.

string mpg_video = _mediahandler.Convert_Media_To_MPEG(outfile, _ffmpegpath, InputPath, OutputPath);
//where mpg_video is the name of mpg video that is generated and stored in mpg folder.
