CMPMediaRecognizer is basically used to identify the type of the media file, for example can local audio or video file,local audio play list, local Ram file etc. Its also used to check the valid Url and also MIME type of the file.
Below is the example code which demostrate CMPMediaRecognizer usuage.
CMPMediaRecognizer* iMPRecognizer = CMPMediaRecognizer::NewL();
//Recognizes media type, returns TMPMediaType which contains different media files
aType = iRecognizer->IdentifyMediaTypeL(KVideo,EFalse);
if (aType == 0)
//Recognizes Media files MimeType.
aText = iRecognizer->MimeTypeL(KVideo);
//Checks if Url is valid or not.
TBool validUrl = iRecognizer->ValidUrl(KUrl);
