RTCOutboundRtpStreamStats: keyFramesEncoded property

{{APIRef("WebRTC")}}{{SeeCompatTable}}

The keyFramesEncoded property of the {{domxref("RTCOutboundRtpStreamStats")}} dictionary represents the total number of key frames successfully encoded in this RTP media stream. This includes, for example, key frames in VP8 ({{rfc("6386")}}) or IDR-frames in H.264 ({{rfc("6184")}}).

Note that the number of delta frames is calculated by subtracting this value from the total number of frames ({{domxref("RTCOutboundRtpStreamStats.framesEncoded","framesEncoded")}} - keyFramesEncoded).

[!NOTE] The value does not exist for audio.
