Frigate NVR Updates: Frame Memory and Startup Fixes
Hawkeye217 landed fixes to keep frame shared memory mapped and to unblock restream startup delayed by heavy detector imports, plus player and docs corrections. The pattern is lower overhead and more reliable startup, with an open change targeting idle CPU from thread pools.

Hello, it's October 13th, 2026, you're listening to Frigate N V R Updates.
The big story is efficiency under load: keeping frame handling cheap and fixing a startup race that left cameras with nowhere to connect.
First, frame memory. In PR 24644, readers no longer close and reopen shared memory for every frame. That old pattern forced a page fault on every page of a fresh mapping each time — roughly hundreds per 1080p frame per process. Now mappings stay open, capture stamps each slot with its frame time, and readers skip a…
Second, startup ordering and idle waste. PR 24648, captured in commit e61ad52, moves environment helpers out of the configuration package. Previously, building the restream config pulled in every detector plugin, and since the O N N X runtime bump that import can take about five seconds. That delayed the restream…
Finally, small correctness fixes. PR 24643 repairs the buffer trim loop in the M S E player, and PR 24649 corrects the shared memory calculator in the docs, which matters for sizing deployments correctly.
What's next: watch testing on the open thread pool change and expect more stable restarts with the memory and startup fixes in place.
