Method Detail

incomingPacketInfo

public void incomingPacketInfo(long arrivalTimeMs,
                               long sendTime24bits,
                               int payloadSize,
                               long ssrc)

Notifies this instance of an incoming packet.

Specified by:

incomingPacketInfo in interface RemoteBitrateEstimator

Parameters:

arrivalTimeMs - the arrival time of the packet in millis.

sendTime24bits - the send time of the packet in AST format (24 bits, 6.18 fixed point).

payloadSize - the payload size of the packet.

ssrc - the SSRC of the packet.

onRttUpdate

public void onRttUpdate(long avgRttMs,
                        long maxRttMs)

Specified by:

onRttUpdate in interface CallStatsObserver

getLatestEstimate

public long getLatestEstimate()

Returns the estimated payload bitrate in bits per second if a valid estimate exists; otherwise, -1.

Specified by:

getLatestEstimate in interface RemoteBitrateEstimator

Returns:

the estimated payload bitrate in bits per seconds if a valid estimate exists; otherwise, -1

getSsrcs

public Collection<Long> getSsrcs()

Returns the estimated payload bitrate in bits per second if a valid estimate exists; otherwise, -1.

Specified by:

getSsrcs in interface RemoteBitrateEstimator

Returns:

the estimated payload bitrate in bits per seconds if a valid estimate exists; otherwise, -1

removeStream

public void removeStream(long ssrc)

Removes all data for ssrc.

Specified by:

removeStream in interface RemoteBitrateEstimator

setMinBitrate

public void setMinBitrate(int minBitrateBps)

Sets the minimum bitrate for this instance.

Specified by:

setMinBitrate in interface RemoteBitrateEstimator

Parameters:

minBitrateBps - the minimum bitrate in bps.

convertMsTo24Bits

public static long convertMsTo24Bits(long timeMs)

Converts rtp timestamps to 24bit timestamp equivalence

Parameters:

timeMs - is the RTP timestamp e.g System.currentTimeMillis().

Returns:

time stamp representation in 24 bit representation.
