Detailed Description

Static payload format objects.

Class of payload formats objects for payload types statically assigned. Because these payloads have an RTP clock rate assigned, it is not specified to the constructor. A call to StaticPayloadFormat(sptPCMU) will set the proper clock rate and any other parameters for that static payload type.

Constructor & Destructor Documentation

StaticPayloadFormat::StaticPayloadFormat

(

StaticPayloadType

type

)

Constructor.

Builds a payload format from a static payload binding identifier, assigning the numeric identifier and RTP clock rate statically bounded.

Parameters

type	Numeric identifier in the range 0-96.

Note

some identifiers are reserved.

Definition at line 90 of file rtppkt.cpp.

Member Function Documentation

PayloadType PayloadFormat::getPayloadType ( ) const

inlineinherited

Get payload type numeric identifier carried in RTP packets.

Returns

payload type numeric identifier.

Definition at line 137 of file formats.h.

uint32 PayloadFormat::getRTPClockRate ( ) const

inlineinherited

Get RTP clock rate for this payload format.

Note this method provides the RTP clock rate (for the timestamp in RTP data packets headers), which is not necessarily the same as the codec clock rate.

Returns

RTP clock rate in Hz.

Definition at line 148 of file formats.h.

void PayloadFormat::setPayloadType ( PayloadType  pt )

inlineprotectedinherited

Set payload type numeric identifier carried in RTP packets.

Parameters

pt	payload type number.

Definition at line 169 of file formats.h.

void PayloadFormat::setRTPClockRate ( uint32  rate )

inlineprotectedinherited

Set RTP clock rate.

Parameters

rate	RTP clock rate in Hz.

Definition at line 177 of file formats.h.

RTP clock rate for static payload types.

There is no need for a table like this for video types, since they all have 90000 Khz rate.
