# Backfill Av1

`POST /internal/admin/backfill-av1`

Enqueue AV1 delivery transcodes for this org's existing library.

Requires org.av1_delivery_enabled (403 otherwise — prevents accidental
transcode spend for non-cohort orgs). Eligible: published+ready video
with a Mux asset, not protected, no av1_mappings row yet, and within
settings["av1_content_tags"] scope if configured. Idempotent — named
Cloud Tasks and the mapping-row PK both dedupe; paginate with
limit+offset until enqueued == 0. Throughput is bounded by the
av1-transcode-jobs queue (max 5 concurrent dispatches).
