Detailed Description

RTP link meter.

Computes various link metrics based on sequence of RTP packets. Inserted into pipeline in two points:

• As a writer, right after receiving packet, before storing packet in incoming queue. Here LinkMeter computes metrics that should be updated as early as possible.
• As a reader, right before decoding packet. Here LinkMeter computes metrics that can be updated only when packets are going to be played.

In both cases, LinkMeter passes through packets to/from nested writer/reader, and updates metrics.

explicit

Initialize.

Member Function Documentation

encoding()

const Encoding & roc::rtp::LinkMeter::encoding

(

)

const

Get detected encoding.

Remarks

Panics if no encoding detected.

has_encoding()

bool roc::rtp::LinkMeter::has_encoding

(

)

const

Check if packet encoding already detected.

has_metrics()

virtual bool roc::rtp::LinkMeter::has_metrics ( ) const

virtual

Check if metrics are already gathered and can be reported.

Implements roc::packet::ILinkMeter.

metrics()

virtual const packet::LinkMetrics & roc::rtp::LinkMeter::metrics ( ) const

virtual

Get metrics.

Implements roc::packet::ILinkMeter.

process_report()

void roc::rtp::LinkMeter::process_report

(

const rtcp::SendReport &

report

)

Process RTCP report from sender.

Remarks

Obtains additional information that can't be measured directly.

read()

virtual status::StatusCode roc::rtp::LinkMeter::read ( packet::PacketPtr &  packet )

virtual

Read packet and update metrics.

Remarks

Invoked late in pipeline right before the packet is decoded.

Implements roc::packet::IReader.

set_reader()

void roc::rtp::LinkMeter::set_reader

(

packet::IReader &

reader

)

Set nested packet reader.

Remarks

Should be called before first read() call.

set_writer()

void roc::rtp::LinkMeter::set_writer

(

packet::IWriter &

writer

)

Set nested packet writer.

Remarks

Should be called before first write() call.

write()

virtual status::StatusCode roc::rtp::LinkMeter::write ( const packet::PacketPtr &  packet )

virtual

Write packet and update metrics.

Remarks

Invoked early in pipeline right after the packet is received.

Implements roc::packet::IWriter.
