Each record represents one video stream. One video media line usually contains two video streams.

Column Data Type Key/Index Details

Average network jitter from Real Time Control Protocol (RTCP) statistics.

JitterInterArrivalMax

Int

 

Maximum network jitter during the video session.

RoundTrip

int

 

Round trip time from RTCP statistics.

RoundTripMax

int

 

Maximum round trip time for the video stream.

PacketLossRate

decimal(5,4)

 

Average packet loss rate during the call.

PacketLossRateMax

decimal(5,4)

 

Maximum packet loss observed during the call.

BurstDensity

decimal(9,4)

 

Not available.

BurstDuration

Int

 

Not available.

BurstGapDensity

decimal(9,4)

 

Not available.

BurstGapDuration

Int

 

Not available.

PacketUtilization

Int

 

Packet count for the video stream (Real Time Transport Protocol, RTP).

BandwidthEst

Int

 

Bandwidth estimates for the video stream.

VideoPayloadDescription

varchar(256)

 

Video codec used.

VideoPayloadType

int

 

Not used.

VideoResolution

char(9)

 

Resolution of the video in pixels width multiplied by pixels height. Reported as a string.

VideoBitRateAvg

int

 

Average bit rate of the video stream.

InboundVideoFrameRateAvg

decimal(9,4)

 

The video frame rate received.

OutboundVideoFrameRateAvg

decimal(9,4)

 

The video frame rate sent.

VideoBitRateMax

int

 

The maximum video bit rate during the video session.

VideoPacketLossRate

decimal(5,4)

 

The average fraction of video packets lost as specified in RFC 3550, computed over the duration of the session.

VideoFrameLossRate

decimal(9,4)

 

The percentage of total video frames that are lost.

VideoFrameEncodingTime

decimal(9,2)

 

Average encoding time for video frames during the video session.

VideoFrameDecodingTime

decimal(9,2)

 

Average decoding time for video frames during the video session.

VideoFEC

bit

 

Not available.

FrozenVideoFreq

decimal(9,4)

 

Frequency of frozen video occurring (occurrences per second).

FrozenPeriodPercentAvg

decimal(7, 4)

 

A measure of the percentage of the duration of the video call in which frozen video was experienced. For good quality, this should be less than 10%.

ConsecutivePacketLossAvg

decimal(20,2)

 

Average number of consecutive video packets lost during the call. For good quality this should be less than 3.0 for a video call.

RateMatchLevel

decimal(4,2)

 

Represents the average level of rate matching applied by the Audio/Video Conferencing Server on the send channel. 0 is no frame removal, 1 is B frame removal, 2 is B and P frame removal, and 3 is B,P,SP removal. For acceptable temporal video quality, this should be 1 or less. An average rate matching level of 1 represents about 7.5 fps for CIF sized video and 12.5 fps for VGA/HD video.

Inbound

bit

 

Stream data on receiver side is received.

Outbound

bit

 

Stream data on sender side is received.

SenderIsCallerPAI

bit

 

1 means the stream direction is from Caller to Callee.

0 means the stream direction is from Callee to Caller.
