 This allows you to verify which recordings are in progress, troubleshoot egress issues, and confirm that recordings are being processed correctly.
 
+## Tuning recording encoding
+
+By default, LiveKit Egress records with the built-in `H264_720P_30` preset: 1280×720 at 30 fps, 3000 kbps H.264 MAIN video and 128 kbps AAC audio. For a one-hour meeting this produces a file of roughly **1.4 GB**, which is often heavier than necessary for talking-head content and screen sharing.
+
+The `RECORDING_ENCODING_*` settings let operators override this preset without modifying the source. Values are passed straight through LiveKit's `EncodingOptions.advanced` to the GStreamer pipeline (`x264enc` for video, `faac` for audio), so there are no hidden conversions — what you set is what the encoder receives.
+
+### How values map to GStreamer
+
+| Setting                               | GStreamer element | Property                           |
+| ------------------------------------- | ----------------- | ---------------------------------- |
+| `RECORDING_ENCODING_WIDTH/HEIGHT`     | capsfilter        | `video/x-raw,width=W,height=H`     |
+| `RECORDING_ENCODING_FRAMERATE`        | capsfilter        | `framerate=F/1`                    |
+| `RECORDING_ENCODING_VIDEO_BITRATE_KBPS` | `x264enc`       | `bitrate=kbps` (kilobits)          |
+| `RECORDING_ENCODING_KEY_FRAME_INTERVAL_S` | `x264enc`     | `key-int-max = interval × fps`     |
+| `RECORDING_ENCODING_AUDIO_BITRATE_KBPS` | `faac`          | `bitrate = kbps × 1000` (bits)     |
+
+The H.264 profile is fixed to MAIN and the x264 `speed-preset` to `veryfast` by LiveKit (real-time constraint) — lowering the framerate is therefore the main lever to save CPU, while lowering the bitrate is the main lever to shrink the output file.
+
+### Reference profiles
+
+Rough 30-minute file-size estimates assume video + audio bitrate multiplied by duration. Actual sizes vary with content (static talking heads compress better than heavy screen motion). Egress CPU figures are indicative, measured on a single Ryzen laptop core saturated by the default preset (= 100 %); scaling is roughly linear with `framerate × bitrate` but the absolute numbers depend on the host hardware.
+
+| Profile                | Resolution | FPS | Video (kbps) | Audio (kbps) | Keyframe (s) | ~ size / 30 min | Egress CPU (vs. default) | Suitable for                                        |

+
+Environment variables for the **Low CPU / small file** profile:
+
+```bash
+RECORDING_ENCODING_ENABLED=True
+RECORDING_ENCODING_WIDTH=1280
+RECORDING_ENCODING_HEIGHT=720
+RECORDING_ENCODING_FRAMERATE=15
+RECORDING_ENCODING_VIDEO_BITRATE_KBPS=600
+RECORDING_ENCODING_AUDIO_BITRATE_KBPS=64
+RECORDING_ENCODING_KEY_FRAME_INTERVAL_S=4.0
+```
+
+### Caveats
+
+- **Screen-share readability — think bits/frame, not bitrate**: at 720p, text legibility starts to break down below ~40 kbits/frame (= `bitrate ÷ framerate`). The recommended preset (600 kbps × 15 fps) sits at exactly that threshold, comfortable for talking heads with occasional slide sharing. The same 600 kbps at 30 fps would only deliver 20 kbits/frame and visibly blur dense slides — which is why **lowering framerate is a more screen-share-friendly lever than lowering bitrate**. For deck-heavy or IDE-share meetings, prefer the **Slide-heavy** profile (900 kbps × 15 fps ≈ 60 kbits/frame).
+- **Motion handling**: the `veryfast` x264 preset is set by LiveKit and cannot be overridden here. Low-bitrate settings will therefore show more artefacts on fast motion than an offline re-encode with a slower preset would. This is the other reason FPS reduction is the safer tuning lever for meeting recordings.
+- **Audio**: AAC at 64 kbps stereo is transparent for voice but starts to compress music noticeably. Keep 128 kbps if you expect music playback in meetings.
+- **Codec choice**: H.264 MAIN is hardcoded on purpose. Switching to HEVC or VP9 would increase egress CPU cost 2×–5×, defeating the goal of this tuning.

+ *    middleware has already set the `csrftoken` cookie via the auth
+ *    redirect, so we read it from `document.cookie` and echo it back
+ *    as `X-CSRFToken`. The middleware verifies the header matches the
+ *    cookie. No `csrfToken` argument needed — `getCsrfToken()` handles it.
+ *
+ * 2. Body-passed token: used by `poll`, called from the Office dialog /
+ *    taskpane iframe. Cookie access inside Office iframes is unreliable
+ *    across Outlook clients, so we can't depend on `document.cookie`
+ *    being populated. Instead, `init` returns the CSRF token in its JSON
+ *    response body, and callers pass it explicitly to subsequent calls.
+ *    The token still travels as `X-CSRFToken` — only its source differs.

+ * The `csrfToken` parameter takes precedence when provided; falls back

+
+    Implements a three-step flow that lets a third-party add-on (running in an
+    embedded iframe) obtain an access token without exposing it to client-side
+    JavaScript:
+
+    1. /init: the add-on opens a session and receives a short-lived transit
+       token (used to bootstrap the OAuth-style exchange in a dialog) and a
+       CSRF token. The opaque session id is stored in an HttpOnly, Secure,
+       SameSite=None cookie so it can accompany cross-origin polls.
+    2. /poll: the add-on polls until the session transitions from pending to
+       authenticated. On the terminal read, the session payload (access
+       token, token type, expiry, etc.) is returned, the session is evicted
+       server-side, and the session cookie is cleared so the tokens can be
+       retrieved exactly once.
+    3. /exchange: called from the post-login callback page on our own domain,
+       after the user has authenticated in a dialog opened by the addon. The
+       transit token (carried client-side via postMessage + sessionStorage)
+       is redeemed here for the authenticated user's access token, which is
+       stored server-side against the session. Requires an authenticated
+       user — that user is whose access token gets bound to the session.
+
+    /init and /poll authenticate the caller through the session cookie +
+    CSRF token pair alone — no user login is required, since the whole point
+    of the flow is to bootstrap one. /exchange, by contrast, requires an
+    authenticated user and does not use the addonsSid cookie.

+    This viewset provides CRUD operations and additional actions for managing files.
+
+    ### API Endpoints:
+    1. **List**: Retrieve a paginated list of files.
+       Example: GET /files/?page=2
+    2. **Retrieve**: Get a specific file by its ID.
+       Example: GET /files/{id}/
+    3. **Create**: Create a new file.
+       Example: POST /files/
+    4. **Update**: Update a file by its ID.
+       Example: PUT /files/{id}/
+    5. **Delete**: Soft delete a file by its ID.
+       Example: DELETE /files/{id}/
+
+
+    ### Ordering: created_at, updated_at, title
+
+        Example:
+        - Ascending: GET /api/v1.0/files/?ordering=created_at
+
+    ### Filtering:
+        - `is_creator_me=true`: Returns files created by the current user.
+        - `is_creator_me=false`: Returns files created by other users.
+        - `is_deleted=false`: Returns files that are not (soft) deleted
+
+        Example:
+        - GET /api/v1.0/files/?is_creator_me=true
+        - GET /api/v1.0/files/?is_creator_me=false&is_deleted=false
