RTCRtpStreamStats.sliCount

The sliCount property of the RTCRtpStreamStats dictionary indicates how many Slice Loss Indication (SLI) packets were received by the sender. An SLI packet is used by a decoder to let the encoder know that it's detected corruption of one or more consecutive macroblocks in the received media.

Syntax

var sliCount = RTCRtpStreamStats.sliCount;

Value

An unsigned long integer indicating the number of SLI packets the sender received from the receiver due to lost runs of macroblocks. A high value of sliCount may be an indication of an unreliable network.

For technical details, see RFC 4585: 6.3.2.

Note: This value is sent by the sender to the receiver and is only present for video media.
