VideoStream Table
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Each record represents one video stream. One video media line usually contains two video streams.

PacketLossRate |
decimal(5,4) |
|
Average packet loss rate during the call. |

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. |

decimal(9,2) |
|
Average decoding time for video frames during the video session. |
VideoFEC |

|
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. |
