- Settings: drop AMPP tab, rename GPU/Transcoding → Proxy encoding
with explicit 'applied to every ingested file' wording, expose
CPU codec/preset options when GPU is off
- New Capture SDKs tab (Settings): upload Blackmagic / AJA / Deltacast
SDK archives (.zip / .tar.gz) staged to /sdk/<vendor>/ inside mam-api;
BMD is fully wired into the FFmpeg build pipeline, AJA + Deltacast
staging-only pending FFmpeg patches
- mam-api: new /api/v1/sdk routes (multer upload, extract, list, delete);
Dockerfile gets unzip+tar; docker-compose mounts /mnt/NVME/MAM/sdk:/sdk
- proxy worker now reads proxy-encoding settings from DB on every job,
builds args for libx264 / NVENC / VAAPI, falls back to libx264 on
hardware-encode failure
- settings GET /s3 falls back to S3_* env vars when DB is empty so the
UI reflects what's actually wired (fixes 'not configured' false alarm)
