Hi Peter, from the spec text: "If videoKeyFrameIntervalCount is not null ... the video encoder produces a keyframe on the *first* frame arriving *after* *videoKeyFrameIntervalCount frames passed* *since* the last key frame"
It sounds to me like the blink impl is correctly implementing the spec meaning. If videoKeyFrameIntervalCount is 0, the spec text implies every frame should be a key frame. If your alternative interpretation were true, what would a value of 0 mean?
