Prosody RTP processing: API: sm_vmptx_config_codec_melpe
Prototype Definition
int sm_vmptx_config_codec_melpe(struct sm_vmptx_codec_melpe_parms *codecp)
Parameters
- *codecp
-
a structure of the following type:
typedef struct sm_vmptx_codec_melpe_parms {
tSMVMPtxId vmptx; /* in */
tSM_INT payload_type; /* in */
tSM_INT ptime; /* in */
} SM_VMPTX_CODEC_MELPE_PARMS;
Description
This requires the module
melpe
to have been downloaded.
Fields
- vmptx
- The VMP[tx] to which to add the codec
- payload_type
- The payload type identifer to use with this codec (see
IETF RFC 3550
section 13). Supplying a value of
-1
will remove any payload type configuration from the
codec preventing its use.
- ptime
- The length of the RTP media, in milliseconds, to send in each packet.
It is usually desirable to send 20 ms packets. Applications
should specify
ptime
as a multiple of 10 ms.
Returns
0
if call completed successfully, otherwise a standard error such as:
- ERR_SM_DEVERR - device error
