Coalesce pending requests across cuts, RTCP feedback, and periodic forcing without delaying video frames. Add the mixer CLI option, native node tests, and a 16-input NVENC rapid-cut/fade regression. Validated 133 mixer/timing tests and 18 native limiter tests, plus isolated 60 fps NVENC A/B runs.

Replace the per-version directories with a single deps/ffmpeg/8/ series that applies to both upstream n8.0 and n8.1. The composition-suite sources are new files (no base context), and the remaining patches are regenerated with minimal context; the only real 8.0/8.1 difference is the libnpp configure check 8.1 added that fails on CUDA 13, which the shared apply.sh rewrites to the stream-context probe (a no-op on 8.0). verify.sh checks either base against a pinned tree in 8/bases.env. Remove the 7.1.5 series and the triplicated per-version verify/README/ base.env; the three demo Dockerfiles call apply.sh and default to n8.1. Net: -5.1k lines of duplicated patch text, one README instead of three. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

… shutdown fixes Every source is normalised to the canvas contract (sdr, hlg, pq) on the GPU by the new tonemap_cuda filter; P010/P210 canvases with 8-bit sources promoted in the compositor; v210 sources stay 4:2:2; HEVC Main10 with HLG/PQ signalling and HDR10 static metadata on outputs; filter EOF-tail, Python shutdown and seek latch fixes; per-node GIL release. Compositor and orchestrator split into modules under src/mixer (primitives/, orchestrator/), libav/avcpp reused where the code re-implemented them; the mixer library ships as pyplumber.mixer. Show files gain working_format, color, latency_ms, v210 sources, tone-mapped renditions and HDR10 metadata; docs and examples follow. Squash of PR #33 (78 commits) onto develop after #34.

Moves the demo builds to FFmpeg 8.1 by default, with FFmpeg 8.0 also supported by the same ordered patch series. Removes the duplicated 7.1.5 and 8.1 directories in favor of
deps/ffmpeg/8/.bases.env. Shared apply/verify scripts handle the version-specific NPP configure probe.Validation: the seven-patch series applies to both n8.0 and n8.1 and reproduces both pinned trees. Overlay Python tests pass (10 tests and 3 subtests). Prior FFmpeg 8.1 GPU validation covered mixer video/browser inputs, transitions, NVENC output, the overlay pixel-reference matrix and recorder reconnect behavior. FFmpeg 8.0 is verified for patch application; no new 8.0 GPU runtime claim is made.
