Sample Code: 3GP Encoding Updated Code
3GP Encoding from other video formats using Process() method
_mhandler.FileName = "sample.wmv";
_mhandler.OutputFileName = "sample";
_mhandler.OutputExtension =".3gp";
_mhandler.VCodec= "h263";
_mhandler.ACodec="libopencore_amrnb";
_mhandler.Channel= 1;
_mhandler.Video_Bitrate=12.2;
_mhandler.Audio_Bitrate=8000;
_mhandler.FrameRate = 25;
_mhandler.Parameters = " -s qcif";
_mhandler.Process();
3GP Encoding from sequence of images using Process() method
_mhandler.FileName = "sample_%04d.jpg"; // e.g sample_0001.jpg
_mhandler.OutputFileName = "sample";
_mhandler.OutputExtension =".3gp";
_mhandler.VCodec= "h263";

_mhandler.Channel= 1;
_mhandler.Video_Bitrate=12.2;
_mhandler.Audio_Bitrate=8000;
_mhandler.FrameRate = 1; // decrease framerate to increase transition time between
two images
_mhandler.Parameters = " -s qcif";
_mhandler.Process();
// Check for errors
if (info.ErrorCode > 0)
{
Response.Write("Video processing failed, Error code " + info.ErrorCode
+ " generated");
return;

Sample Code: Encode video to 3gp format - C#
Using Encode_3GP() function default options
// Sample code for encoding any format video to .3gp format.
MediaHandler _mhandler = new MediaHandler();
// required properties
string RootPath = Server.MapPath(Request.ApplicationPath);
_mhandler.FFMPEGPath = HttpContext.Current.Server.MapPath("~\\ffmpeg\\ffmpeg.exe");
_mhandler.InputPath = RootPath + "\\contents\\video";
_mhandler.OutputPath = RootPath + "\\contents\\3gp";
_mhandler.FileName = "sample.mpg";
// optional output filename
_mhandler.OutputFileName = "sample.3gp";
// publish video to .3gp format with default options.
string output = _mhandler.Encode_3GP();
// this will generate .3gp video with default options. if you want to customize values then set values as shown below.
// setting video related properties
_mhandler.Video_Bitrate = 100;
_mhandler.Audio_Bitrate = 12.2;
_mhandler.Audio_SamplingRate = 8000;
// optional video width and height settings
_mhandler.Width = 176;
_mhandler.Height = 144;
// optional video and audio codec settings, make sure it is compatible with 3gp video otherwise result in failure of video encoding.
_mhandler.ACodec = "libamr_nb";
_mhandler.VCodec = "h263";
// view more options in component documentation.
// Encode 3GP Video using Media Handler Pro version 3.0
string output = _mhandler.Encode_3GP();
// Encode 3GP Video using Media Handler Pro version 4.0 or later
VideoInfo info = _mhandler.Encode_3GP();
// Check for errors
