* Initialize a Codec 
* @param self The codec to initialize. Could be any type of codec (e.g. @ref tmedia_codec_audio_t or @ref tmedia_codec_video_t).
* @param type
* @param name the name of the codec. e.g. "G.711u" or "G.711a" etc used in the sdp.
* @param desc full description.
* @param format the format. e.g. "0" for G.711.u or "8" for G.711a or "*" for MSRP.
* @retval Zero if succeed and non-zero error code otherwise.
