The rtp header extension for video timing shuold have an additional field for signaling metadata, such as what triggered the extension for this particular frame. This will allow separating frames select because of outlier sizes from regular frames, for more accurate stats. This implementation is backwards compatible in that it can read video timing extensions without the new flag field, but it always sends with it included.
