about

nx_cam_poster_batch.nx -- STEP 5 poster generator writing the <recording>-poster.jpg SIBLING that the LIVE gallery serve already serves at GET /vidthumb/<id> (gs_vidthumb -> gs_poster_path -> read+serve). ZERO serve change: the daemon serves the sibling the instant it exists. poster_sibling() is byte-identical to the serve's gs_poster_path (truncate at the last '.', append "-poster.jpg"). nx_cam_poster_batch one <id> -- generate ONE recording's poster (on-demand, by catalog id) nx_cam_poster_batch <start> <count> -- generate a range (idempotent skip-existing, forks 1 child/rec) Forks nx_cam_poster (bounds memory: 8MiB scan + a frame, no munmap, reclaimed on child exit); skips CABAC gracefully (child rc==10). Run from cwd=/volume1/ai/galx (the serve's cwd, where CATALOG resolves). license_tier: ORIGINAL
