c++ cli - How do i get the codec's List of ffmpeg by names? -

i have function in c

int encoder_getcurrentcodectype() {     if (current_codec != null)         return (int) current_codec->type;     return avmedia_type_unknown; } 

but function return code of each codec type. like: 0,1,2,3,4,5,6,7

if i'm doing test in function type: avmediatype:: see list of 7 codec's types there example:

avmedia_type_audio 

so want make function 1 int string or const char* return me names of types , not codes.

how can ?

edit

in c file did:

const char* encoder_av_get_media_type_string(enum avmediatype media_type) {     switch (media_type) {         case avmedia_type_video:      return "video";         case avmedia_type_audio:      return "audio";         case avmedia_type_data:       return "data";         case avmedia_type_subtitle:   return "subtitle";         case avmedia_type_attachment: return "attachment";         default:                      return null;         } } 

then in header file connecting between c , c++ did:

const char* encoder_av_get_media_type_string(enum avmediatype media_type); 

then in c++ header file did:

property list<string^> ^getcodec {      list<string^>^ get()     {         list<string^> ^l = gcnew list<string^>;         string ^s;           s = gcnew string(encoder_av_get_media_type_string(avm));         l->add(s);           return l;     } } 

then in csharp did:

for (int = 0; < f.getcodec.count; i++)             {                 ss.add(f.getcodec[i]);             } 

so maybe in c++ shouldn't property thought in csharp when make f.getcodec. show me list of codec's types names.

like property when i'm doing f.getcodec.add , see list of properties f.getcodec.(and here list of types names)

if it's impossible make in csharp list types names.

but i'm getting 1 name "video" that's it.

according this, there exists function that.

const char* av_get_media_type_string(enum avmediatype media_type)
