| * |
| * This section describes functions to register and register passthrough |
| * codecs factory to the codec manager. After the codec factory has been |
| * registered, application can use @ref PJMEDIA_CODEC API to manipulate |
| * the codec. This codec factory contains various codecs, e.g: G.729, iLBC, |
| * AMR, and G.711. |
| * |
| * Passthrough codecs are codecs wrapper that does not perform encoding |
| * or decoding, it just pack and parse encoded audio data from/into RTP |
| * payload. This will accomodate pjmedia ports which work with encoded |
| * audio data, e.g: encoded audio files, sound device with capability |
| * of playing/recording encoded audio data. |
