* refactor(node): move video streaming out of webrtc_serverChristophe Besson25 hours1-1/+2
| | | | | | | StreamingMixin in transport/webrtc/apps/streaming.py: stream credit, handover, the transcode slots and _stream_video_inner, moved unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* style: ruff's own fixes, mechanically appliedChristophe Besson6 days1-1/+0
| | | | | | | | | | | | | | | | | | | | `ruff check .` had gone unrun long enough to report 568 errors, which is the same as having no linter: the next real finding would have been invisible in the noise. This is the 521 it fixes by itself, in 173 files, and nothing else — the 98 it cannot fix are the next commit. What actually changed: import sorting (225), imports nobody used (87, none of them a re-export — no `__init__.py` is touched, which was the one way this could have broken an import elsewhere), `datetime.timezone.utc` to `datetime.UTC` (69) and `asyncio.TimeoutError` to `TimeoutError` (18), both plain aliases on the 3.12 this project requires, `Optional[X]` to `X | None` (24), and f-strings with nothing to interpolate (19). Checked rather than assumed: every module in the three packages still imports, and the suite is 2893 passed — the same count, test for test, as the merge before it.

* docs: cite MESHBAY_DESIGN.md and a section instead of the merged notesChristophe Besson7 days1-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The per-feature design notes were merged into docs/MESHBAY_DESIGN.md and deleted from the tree on 2026-09-11, but ~230 comments across the three packages still named them — usually written `docs/musicbay.md §3.2`, as though the file were still in docs/. A reader had to know §16 existed to resolve any of them. They now name the section directly. Every mapping comes from §16, the concordance, which already records where each old section landed: musicbay -> §9.8, mediacenter -> §9.7 for the Videos app and §6.5 where the subject is derived data, photos -> §9.9, auth-confirm -> §3.6, refactoring-search -> §9.11, invite-pairing-v1 -> §3.4, per-node-identity-v1 -> §3.2, captcha -> §7.7, chat-sender-keys -> §4.5, apps/refactor-groups -> §9.1–§9.4, desktop-client-v1 per section. Bare citations of the same documents (`draft-v6 §2.11`, `§4.8`, `§3.4`) are retargeted too: those collide with real section numbers in the design document, so leaving them would have been worse than the named form. Four cases the concordance does not cover, each decided rather than guessed: Sub-item references into documents that no longer exist — mediacenter's `§3.3 row 4`, `§3.4b/c`, `apps.md §3b` — name rows and sub-items §9.7 and §9.2 do not reproduce. The module-level citation stays; the sub-item pointer is dropped. The V-findings keep their labels but lose the dead `§10.1/` prefix. §13.8 lists V1–V13 as per-application open items, which is not what the labels mean in these comments, so pointing them at §13.8 would have been a false citation. `apps.md §5`'s virtualization requirement has no counterpart anywhere in the design document. The requirement is stated in the comment itself, so the citation is dropped rather than aimed at a section that does not say it. Comments that attributed a *sentence* to an old note — musicbay's "several thousand files" example, its "what got measured" note, its measured ~11%/~26% cover-art figures, the "original no root, whole shared tree" call — state the fact without attribution now. §9.8 does not contain those sentences and citing it for them would have been wrong. CLAUDE.md's "a reference to a document that no longer exists" row now says the concordance is for git history and out-of-tree material; the code cites sections directly. Verified: 2851 passed, 4 skipped. The 12 errors in the run are the Firefox leg of test_sticky_header.py's browser harness, which is broken at the browser level on this machine — headless Firefox (snap) dies with `[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer`, renders nothing, and the probe exits `{"error": "no measurement"}` after its full 90s wait. Chrome runs the same 12 assertions in 3.2s and passes. Nothing here can affect it: every changed line in style.css is inside a comment. Also checked: ast.parse on every changed .py, `node --check` on every changed .js, the /* */ balance in style.css, and that no changed line exceeds the width its file already used.

* feat: decode and re-encode video on the GPU where there is oneChristophe Besson7 days1-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A 1080p film is decoded by whoever watches it and re-encoded by the node when no browser can decode the source. Both were on the CPU, and on an Atom or Celeron mini-PC neither reaches real time — which is what `transcode_incompatible_video` exists to refuse. This adds the mechanism that makes refusing it unnecessary. Node — `hwaccel.py`: VA-API on Linux, Quick Sync or NVENC on Windows, established by encoding 1080p and reading the file back with ffprobe. Nothing is accepted that does not produce the exact profile and level `stream_init` announces, since the client checks that string before it trusts a byte: an encoder that wrote another level would make the node's own codec string a lie, and ffmpeg takes `-level 4.1` and `-level 41` from h264_qsv without saying which it understood. Three modes per stream — hardware decode and encode, hardware encode alone, libx264 — demoted per source codec, because a GPU that decodes HEVC may have no decoder for MPEG-4 Part 2 and only asking it finds out. A mode that fails is detected on an empty stdout before `stream_init` goes out, so the viewer sees one working stream and never an error. Client — Chromium ships VA-API off on Linux. It is enabled where a render node and a driver are present, then verified through `navigator.mediaCapabilities`: a no moves to the next GL backend on the next launch and an exhausted list drops the switches, so a renamed feature cannot pass for a feature that is on and `--ignore-gpu-blocklist` cannot survive on a machine it did not help. Feature lists now merge rather than overwrite — `appendSwitch` replaces the value, and a second caller would have silently cancelled the mDNS switch aiortc depends on. Packaging — the drivers are weak dependencies on all four formats, so a machine without a GPU installs exactly as before. `dpkg -i` and `rpm -ivh` ignore weak deps; `packaging/README.md` now says so. Windows needs no driver: the bundled ffmpeg already carries h264_qsv and h264_nvenc, and a re-pin that dropped them would cost every low-power Windows node its hardware encoding silently. AMD on Windows (AMF) and macOS (VideoToolbox) are named gaps, not oversights: neither could be tried anywhere in this project, and both re-encode in software as before.

* feat: let the viewer pick the audio trackChristophe Besson8 days1-8/+8
| | | | | | | | | | | | | The streaming path mapped 0:a:0 unconditionally, so a dubbed film played in whichever language was muxed first and the others were unreachable. The node now enumerates the tracks in stream_init and honours audio_track in stream_req; switching is the seek path, since one ffmpeg carries one track. MNP 3.2, additive: the player draws its selector from the node's own list and never from a version number, so an older node is never asked for a track it would ignore. MNP_MIN_SUPPORTED does not move. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(node): a video the browser cannot decode is re-encoded, not refusedChristophe Besson2026-09-091-0/+273
Streaming an Xvid/MP3 .avi answered "Unsupported video codec" — a refusal, on a file ffmpeg re-encodes at about six times playback speed on the machine that reported it. Nothing about the source was wrong. The node simply never reached its own re-encode path. `probe_video` maps a source codec to an MSE codec string and knows four: h264, hevc, vp9, av1. Everything else returns None, because there is no MediaSource decoder in any mainstream browser to give a string to — MPEG-4 Part 2 (Xvid, DivX), MPEG-2, VC-1, WMV, Theora. `_stream_video_inner` read that None as a verdict on the file and refused, while the re-encode sitting twenty lines below it was gated on `raw_video_codec in BROWSER_INCOMPATIBLE_VIDEO_CODECS` — a set containing "hevc" and nothing else. So the whole ffmpeg fallback existed, worked, and was unreachable for every codec that most needed it. The setting that governs the fallback has documented the intended behaviour since it was introduced: draft-v6 §2.11 says `transcode_incompatible_video` covers "HEVC *and other browser-incompatible video codecs*". Only HEVC was ever wired up. Two questions were being answered by one value, and they are separated now. "Is there a video stream at all" is the only thing this path genuinely cannot serve, and the only refusal left. "Can it be copied" needs both an MSE string to put in `stream_init` and a codec browsers decode; a source failing either is re-encoded. The operator's opt-out keeps meaning what it says, and it no longer means the same thing for every source, because it cannot: HEVC has a codec string, so `transcode_incompatible_video = false` falls back to a copy and the viewer's own decoder decides (unchanged). MPEG-4 Part 2 has none, so there is nothing to fall back to — a `stream_init` with no codec string is one the client refuses before the first byte — and the stream is refused naming the setting. "Unsupported video codec" is what sent this report to the file, and the file was fine. Verified against the reported file end to end: ffprobe reports mpeg4/mp3 720x404, the decision comes out `can_copy=False`, and the pipeline's exact argv produces H264 High level 4.1 plus stereo AAC-LC — matching the `avc1.640029,mp4a.40.2` that `stream_init` advertises and that the client puts through MediaSource.isTypeSupported byte for byte. test_stream_hevc_transcode.py becomes test_stream_video_transcode.py: it was always about the policy rather than about one codec, and it now carries both halves of it, with a synthetic Xvid/MP3 .avi built the same way as the HEVC clip. Its module-level skip on libx265 went with it — an ffmpeg without x265 still encodes MPEG-4 Part 2, so that marker was skipping the reported defect entirely on any box without it; it now gates the HEVC cases alone. Three cases added, checked against the unfixed source. Hub and node suites 2269 passed, 4 skipped.
