The Uniview IPC6322SR-X22P-D (the LPR flagship) is already in the compat DB, but its caveat carried the older diagnosis ("the H265 main's SDP has NO a=fmtp").

The live-restream investigation (#592) showed the truth is more specific: the camera's producer SDP does carry an a=fmtp with sprop-sps + sprop-pps, just no sprop-vps. go2rtc, unable to assemble a complete HEVC parameter set, is what then serves clients a fmtp-less SDP, and that served SDP is the actual Media3 blocker.

Corrects the main-stream note and the quirk detail to that, and adds that Crumb now auto-detects the condition per-camera from the served SDP and the client reaches for the repaired main first (so it starts fast). JSON only (the docs page is regenerated by CI). Removed the pre-existing em-dashes while here.

… cause

The entry described the H265 main as having NO a=fmtp. The live-restream
investigation (2026-08-08) showed the camera's producer SDP DOES carry an a=fmtp
with sprop-sps + sprop-pps but no sprop-vps; go2rtc, unable to build a complete
HEVC parameter set, is what serves clients a fmtp-less SDP, which is the actual
Media3 blocker. Correct the main note and the quirk detail to that, and note the
repair is auto-detected per-camera from the served SDP and reached first by the
client (so it starts fast). Removed the pre-existing em-dashes while here.

Add the back-half-of-cycle work to the [0.2.0] UNRELEASED section: two thematic
subsections (HD live on a phone; Notifications, redesigned), plus curated
Added/Changed/Fixed entries for the LPR plate tooling, timeline solo + SQL
bucketing, the dashboard honesty pass, storage-seed idempotency, and the Frigate
MQTT fix. Upgrading migration range -> 0072 through 0080. Every PR #544-#596 is in
All merged changes. Left UNRELEASED (undated); tagging is the maintainer's step.
