Group PJMED_OC_AMR

group PJMED_OC_AMR

AMRCodec wrapper for OpenCORE AMR codec.

Typedefs

typedef pjmedia_codec_amr_config pjmedia_codec_amrnb_config

typedef pjmedia_codec_amr_config pjmedia_codec_amrwb_config

Enums

enum pjmedia_amr_options

Bitmask options to be passed during AMR codec factory initialization.

Values:

enumerator PJMEDIA_AMR_NO_NB

Disable narrowband mode.

enumerator PJMEDIA_AMR_NO_WB

Disable wideband mode.

Functions

pj_status_t pjmedia_codec_opencore_amr_init(pjmedia_endpt *endpt, unsigned options)

Initialize and register AMR codec factory to pjmedia endpoint.

Parameters:

• endpt – The pjmedia endpoint.

• options – Bitmask of pjmedia_amr_options (default=0).

Returns:

PJ_SUCCESS on success.

pj_status_t pjmedia_codec_opencore_amr_init_default(pjmedia_endpt *endpt)

Initialize and register AMR codec factory using default settings to pjmedia endpoint.

Parameters:

endpt – The pjmedia endpoint.

Returns:

PJ_SUCCESS on success.

pj_status_t pjmedia_codec_opencore_amr_deinit(void)

Unregister AMR codec factory from pjmedia endpoint and deinitialize the OpenCORE codec library.

Returns:

PJ_SUCCESS on success.

pj_status_t pjmedia_codec_opencore_amrnb_init(pjmedia_endpt *endpt)

Initialize and register AMR-NB codec factory to pjmedia endpoint. Calling this function will automatically initialize AMR codec factory without the wideband mode (i.e. it is equivalent to calling pjmedia_codec_opencore_amr_init() with PJMEDIA_AMR_NO_WB). Application should call pjmedia_codec_opencore_amr_init() instead if wishing to use both modes.

Parameters:

endpt – The pjmedia endpoint.

Returns:

PJ_SUCCESS on success.

pj_status_t pjmedia_codec_opencore_amrnb_deinit(void)

Unregister AMR-NB codec factory from pjmedia endpoint and deinitialize the OpenCORE codec library.

Returns:

PJ_SUCCESS on success.

pj_status_t pjmedia_codec_opencore_amrnb_set_config(const pjmedia_codec_amrnb_config *cfg)

Set AMR-NB parameters.

Parameters:

cfg – The settings;

Returns:

PJ_SUCCESS on success.

pj_status_t pjmedia_codec_opencore_amrwb_set_config(const pjmedia_codec_amrwb_config *cfg)

Set AMR-WB parameters.

Parameters:

cfg – The settings;

Returns:

PJ_SUCCESS on success.

struct pjmedia_codec_amr_config

#include <opencore_amr.h>

Settings. Use pjmedia_codec_opencore_amrnb_set_config() and pjmedia_codec_opencore_amrwb_set_config() to activate.
