DESCRIPTION:Speakers: Anna Kim (Pexip AS)\, Misha Baranov (Pexip AS)\nIn v
 ideo conferencing\, network conditions and how they are handled can direct
 ly impact the perceived quality at the receiving end. To measure this degr
 adation\, the correspondence between reference and presented frames must b
 e tracked across hosts in various configurations. Rather than relying on i
 n-band visual markers\, which can be fragile under poor channel conditions
 \, we present a GStreamer-based approach that gives every frame an explici
 t identity\, carried as buffer metadata through the pipeline and as an RTP
  header extension over the wire. We show per-frame quality trajectories un
 der network congestion\, and how quality changes when frames are duplicate
 d or dropped.\n\nhttps://indico.freedesktop.org/event/14/contributions/629
