MSVideoRecvPayload Dictionary

Member	Type	Description
lowBitRateCallPercent	float	Percentage of time of the call where bit rate is 70 kilobits per second or less.
lowFrameRateCallPercent	float	Percentage of time of the call where frame rate is less than 7.5 frames per second.
recvBitRateAverage	unsigned long	The average bandwidth received for all video streams, computed over the duration of the session.
recvBitRateMaximum	unsigned long	The maximum bandwidth received for all video streams, computed over the duration of the session.
recvCodecType	DOMString	Codec name, as specified in [MS-SDPEXT] Section 3.1.5.3 or [RFC3551] Section 6 concatenated by resource type. See [MS-QoE] Section 2.2.1.15.1.2.
recvFpsHarmonicAverage	float	Calculated received FPS using harmonic average.
recvFrameRateAverage	float	Average frames per second received for all video streams, computed over the duration of the session.
recvNumResSwitches	float	How many times the receiver sees a resolution change.
recvReorderBufferMaxSuccessfullyOrderedExtent	unsigned long	The maximum reorder extent in the case where video packets arrive late and FEC has already recovered this packet.
recvReorderBufferMaxSuccessfullyOrderedLateTime	unsigned long	The maximum late time in the case where video packets arrive late and FEC has already recovered this packet.
recvReorderBufferPacketsDroppedDueToBufferExhaustion	unsigned long	The number of video packets dropped due to buffer exhaustion.
recvReorderBufferPacketsDroppedDueToTimeout	unsigned long	The number of video packets dropped due to time out as they arrive late.
recvReorderBufferReorderedPackets	unsigned long	The number of reordered video packets.
recvResolutionHeight	unsigned long	The maximum video image height received for all video streams, computed over the duration of the session.
recvResolutionWidth	unsigned long	The maximum video image width received for all video streams, computed over the duration of the session.
recvVideoStreamsMax	unsigned long	The maximum number of video streams received during any one second interval, computed over the duration of the session.
recvVideoStreamsMin	unsigned long	The minimum number of video streams received during any one second interval, computed over the duration of the session.
recvVideoStreamsMode	long	The most common number ("mode") of video streams received during any one second interval, computed over the duration of the session.
reorderBufferTotalPackets	unsigned long
videoFrameLossRate	float	The average fraction of frames lost on the video receiver side, computer of the duration of the session.
videoPostFECPLR	float	Reports packet loss rate after FEC has been applied for video. Aggregated across all video streams and codecs. Value between 0.00 and 1.00.
videoResolutions	MSVideoResolutionDistribution	Metrics representing the distribution of video resolutions.
