The following settings are applicable for this codec. Please see the documentation of pjmedia_codec_param for more info. General codec settings for this codec such as VAD and PLC can be manipulated through the setting field in pjmedia_codec_param. This behavior can be changed by specifying #pjmedia_codec_silk_options flags during initialization. The SILK codec uses multiple bit rates, and supports super wideband (24 kHz sampling rate), wideband (16 kHz sampling rate), medium (12kHz sampling rate), and narrowband (telephone quality, 8 kHz sampling rate).īy default, the SILK codec factory registers two SILK codecs: "SILK/8000" narrowband codec and "SILK/16000" wideband codec. After the codec factory has been registered, application can use Codec Framework API to manipulate the codec. This section describes functions to initialize and register SILK codec factory to the codec manager. Pjmedia_codec_silk_set_config (unsigned clock_rate, const pjmedia_codec_silk_setting *opt) Pjmedia_codec_silk_init ( pjmedia_endpt *endpt) Implementation of SILK codecs (narrow/medium/wide/superwide-band).
