docs(testing): cover webcam capture quality in the manual e2e checklist

[EtienneLescot]

Summary

Adds the manual e2e checks that #875 needs and nothing in the checklist covered. No check was run, and no row is added to the results log.

• Launch and HUD: the Camera quality choices and default, persistence, a hand-edited value, no row without a camera.
• New section "Webcam capture quality": where the sidecar lives, the exact ffprobe commands, and how to read the Windows helper's negotiated format.
• Checks: file size and bit rate per choice, a camera below the target, frame rate (30, 24, 30 and 60), a change during a take, the no-visible-frame warning both ways, DirectShow, the browser recorder, sharpness against 640x480.
• Camera-class checks are tagged so a run logs skipped: no such camera.
• A pointer in each platform block.

One thing to look at

Reading WebcamCapture::fps(), the Media Foundation path returns the requested rate. Only DirectShow reads back the negotiated one (6974e30). The 24 fps check may fail there. This is from reading the code, not from a run.

Summary by CodeRabbit

• Documentation
  • Expanded the manual testing checklist with v2.0.0 webcam-quality checks for default and saved settings, invalid-setting fallback, and when camera-quality controls are unavailable.
  • Added camera checks for resolution, bitrate, frame rate, image sharpness, recording behavior, missing visible frames, and export quality.
  • Linked the checks from the Windows, macOS, and Linux sections, distinguishing browser-recorder .webm coverage from Windows-helper checks.

📝 Walkthrough

Walkthrough

The manual E2E checklist adds v2.0.0 coverage for webcam resolution settings and capture quality. Windows, macOS, and Linux sections link to applicable checks and specify platform-specific recorder coverage.

Changes

Webcam checklist updates

Layer / File(s)	Summary
Resolution setting checks technical-documentation/testing/manual-e2e-checklist.md	The release summary adds webcam capture resolution and frame rate. Checks cover the 4K default, persistence of 1080p, fallback for an invalid saved value, and hiding the setting when no camera is available.
Capture quality and platform coverage technical-documentation/testing/manual-e2e-checklist.md	The checklist adds procedures for capture resolution, bitrate, frame rate, image integrity, warnings, and capture backends. Platform sections link to these checks and specify which recorder checks apply.

- Line 171: Update the 4K camera check in the shared camera-class checklist to
use platform-specific commands for listing camera modes on macOS and Linux,
while retaining the DirectShow command for Windows. If those platforms cannot
use an equivalent command, limit the existing command to Windows and specify how
macOS and Linux users should identify a camera that supports 3840x2160 or
higher.
- Line 189: Update the no-30-fps checklist item to distinguish Media Foundation
from DirectShow: for Media Foundation, assess the 24 fps source cadence using
delivered frames divided by duration, without requiring webcamFormat.fps or MP4
avg_frame_rate to be 24; for DirectShow, compare webcamFormat.fps and the
connected or negotiated helper rate with the encoded rate settled by the graph.
Preserve the WebM frame-count check.

Add nb_read_frames to -show_entries.

-count_frames reports the count, but the explicit -show_entries list omits nb_read_frames. The WebM check cannot read the count until the field is selected.

Update the ffprobe command in the manual E2E checklist to include nb_read_frames
in the stream fields selected by -show_entries, so the WebM frame-count check
can read the count when using -count_frames.
