Track.setPacketizer(kind, ssrc, pt, clockRate, ...) builds the same
media-handler chain node-datachannel does for @dank074:
RtpPacketizer (Opus | H264 | H265 | AV1) → RtcpSrReporter →
RtcpNackResponder → PacingHandler(25Mbps, 1ms) for video
Track.sendFrame(encodedFrame) packetizes into RTP; addTimestamp(delta)
advances the RTP timestamp (node-datachannel contract).
Verified test-packetizer.js: two peers connected over tracks, real opus
frames + AnnexB H264 (SPS/PPS/IDR) flow through the chain without crash.
This removes the need for a JS RTP packetizer entirely — libdatachannel
0.24 has the full media stack built in.
