The following is a simple example.C #UseWindows Media Encoder SDKDevelopment.

 

Try
{
// Create wmencoder object.
Wmencoder Encoder =   New Wmencoder ();
// Obtain the group Source set
Iwmencsourcegroupcollection srckgcoll = Encoder. sourcegroupcollection;

// Add a group source to the set
Iwmencsourcegroup srmrm = Srckgcoll. Add ( " Sg_1 " );

// Add an audio source and video source to the group Source
Iwmencsource srcaud = Srmrm. addsource (wmenc_source_type.wmenc_audio );
Srcaud. setinput ( " C: \ love. rm " , "" , "" );

Iwmencvideosource2 srcvid = (Iwmencvideosource2) srmrm. addsource (wmenc_source_type.wmenc_video );
Srcvid. setinput ( " C: \ love. rm " , "" , "" );

// Create an output file
Iwmencfile File = Encoder. file;
File. localfilename =   " C: \ outputfile. wmv " ;

// Load the configuration file
Wmencprofile2 pro =   New Wmencprofile2 ();
Pro. loadfromfile ( " C: \ schi. PRx " );
Srmrm. set_profile (Pro );

// Add file description
Iwmencdisplayinfo descr = Encoder. displayinfo;
Descr. Author =   " Author name " ;
Descr. Copyright =   " Copyright information " ;
Descr. Description =   " Text description of encoded content " ;
Descr. Rating =   " Rating Information " ;
Descr. Title =   " Title of encoded content " ;

Iwmencattributes ATTR = Encoder. attributes;
ATTR. Add ( " URL " , " IP address " );

// Start Encoding
Encoder. preparetoencode ( True );
