Group pjmedia_codec_config¶
- group pjmedia_codec_config
Various compile time settings such as to enable/disable codecs.
Defines
-
PJMEDIA_HAS_L16_CODEC¶
Unless specified otherwise, L16 codec is included by default.
-
PJMEDIA_CODEC_L16_HAS_8KHZ_MONO¶
Settings to enable L16 codec 8KHz, mono. By default it is disabled.
-
PJMEDIA_CODEC_L16_HAS_8KHZ_STEREO¶
Settings to enable L16 codec 8KHz, stereo. By default it is disabled.
-
PJMEDIA_CODEC_L16_HAS_16KHZ_MONO¶
Settings to enable L16 codec 16KHz, mono. By default it is disabled.
-
PJMEDIA_CODEC_L16_HAS_16KHZ_STEREO¶
Settings to enable L16 codec 16KHz, stereo. By default it is disabled.
-
PJMEDIA_CODEC_L16_HAS_48KHZ_MONO¶
Settings to enable L16 codec 48KHz, mono. By default it is disabled.
-
PJMEDIA_CODEC_L16_HAS_48KHZ_STEREO¶
Settings to enable L16 codec 48KHz, stereo. By default it is disabled.
-
PJMEDIA_HAS_GSM_CODEC¶
Unless specified otherwise, GSM codec is included by default.
-
PJMEDIA_HAS_SPEEX_CODEC¶
Unless specified otherwise, Speex codec is included by default.
-
PJMEDIA_CODEC_SPEEX_DEFAULT_COMPLEXITY¶
Speex codec default complexity setting.
-
PJMEDIA_CODEC_SPEEX_DEFAULT_QUALITY¶
Speex codec default quality setting. Please note that pjsua-lib may override this setting via its codec quality setting (i.e PJSUA_DEFAULT_CODEC_QUALITY).
-
PJMEDIA_HAS_ILBC_CODEC¶
Unless specified otherwise, iLBC codec is included by default.
-
PJMEDIA_HAS_G722_CODEC¶
Unless specified otherwise, G.722 codec is included by default.
-
PJMEDIA_G722_DEFAULT_PCM_SHIFT¶
Default G.722 codec encoder and decoder level adjustment. The G.722 specifies that it uses 14 bit PCM for input and output, while PJMEDIA normally uses 16 bit PCM, so the conversion is done by applying level adjustment. If the value is non-zero, then PCM input samples to the encoder will be shifted right by this value, and similarly PCM output samples from the decoder will be shifted left by this value.
This can be changed at run-time after initialization by calling pjmedia_codec_g722_set_pcm_shift().
Default: 2.
-
PJMEDIA_G722_STOP_PCM_SHIFT_ON_CLIPPING¶
Specifies whether G.722 PCM shifting should be stopped when clipping detected in the decoder. Enabling this feature can be useful when talking to G.722 implementation that uses 16 bit PCM for G.722 input/ output (for any reason it seems to work) and the PCM shifting causes audio clipping.
See also PJMEDIA_G722_DEFAULT_PCM_SHIFT.
Default: enabled.
-
PJMEDIA_HAS_INTEL_IPP¶
Enable the features provided by Intel IPP libraries, for example codecs such as G.729, G.723.1, G.726, G.728, G.722.1, and AMR.
By default this is disabled. Please follow the instructions in http://trac.pjsip.org/repos/wiki/Intel_IPP_Codecs on how to setup Intel IPP with PJMEDIA.
-
PJMEDIA_AUTO_LINK_IPP_LIBS¶
Visual Studio only: when this option is set, the Intel IPP libraries will be automatically linked to application using pragma(comment) constructs. This is convenient, however it will only link with the stub libraries and the Intel IPP DLL’s will be required when distributing the application.
If application wants to link with the different types of the Intel IPP libraries (for example, the static libraries), it must set this option to zero and specify the Intel IPP libraries in the application’s input library specification manually.
Default 1.
-

Default: 0
-
PJMEDIA_AUTO_LINK_OPENCORE_AMR_LIBS¶
Link with libopencore-amrXX via pragma comment on Visual Studio. This option only makes sense if PJMEDIA_HAS_OPENCORE_AMRNB/WB_CODEC is enabled.
Default: 1
-
PJMEDIA_OPENCORE_AMR_BUILT_WITH_GCC¶
Link with libopencore-amrXX.a that has been produced with gcc. This option only makes sense if PJMEDIA_HAS_OPENCORE_AMRNB/WB_CODEC and PJMEDIA_AUTO_LINK_OPENCORE_AMR_LIBS are enabled.
Default: 1
-
PJMEDIA_G7221_DEFAULT_PCM_SHIFT¶
Default G.722.1 codec encoder and decoder level adjustment. If the value is non-zero, then PCM input samples to the encoder will be shifted right by this value, and similarly PCM output samples from the decoder will be shifted left by this value.
This can be changed at run-time after initialization by calling pjmedia_codec_g7221_set_pcm_shift().
-
PJMEDIA_HAS_SILK_CODEC¶
Enabling both G.722.1 codec implementations, internal PJMEDIA and IPP, may cause problem in SDP, i.e: payload types duplications. So, let’s just trap such case here at compile time.
