The trickiest reading on the disc lived in the Bevy viewer: resolving a cutscene's voice to a continuous byte REGION of the sound stream, because the movie voices are one XMA stream chunked into VOICE_*.slb entries whose boundaries do not match the cues -- a cue routinely spans two chunks, so a .slb need not hold the track its name claims. That put the logic most likely to be re-derived incorrectly in the crate least likely to be reused. The Godot port's exporter needs the same answers, and there must be one implementation of them. New `sylpheed_formats::media` owns every case where the bytes of one playable thing are not one archive entry: segment-spanning reads, multi-sub-wave banks, and the voice-region resolution. Callers supply bytes through a `DiscSource` trait, so the viewer keeps its ISO/directory abstraction and a headless consumer gets `DirectorySource` for free. The seam is deliberate: this module returns XMA RIFFs, not PCM. Decoding means shelling out to FFmpeg, which is native-only and a policy decision for the consumer -- everything up to "here are the bytes that belong together" is disc knowledge, everything after it is a codec choice. The four moved functions were previously untested; `tests/media_disc.rs` now pins them, including the negative the corpus paid for -- an unbound movie must stay unvoiced rather than borrow a neighbour's clip, which was tried and played the WRONG recording. The algorithm is unchanged, moved verbatim (same window sizes, same fallbacks). The new disc tests pass; the broader audio suite was not re-run in this pass.

# Catch a screen being BUILT, not sitting still.

#
|
|
# `log_ui_draws` armed at the title only ever sees the steady state, and the
|
|
# steady state is the one thing an animation question cannot be asked of. The
|
|
# build — the wordmarks zooming in, the effect sprites wiping across, the black
|
|
# fade lifting — happens in the seconds BEFORE the screen classifier can call it
|
|
# a title.
|
|
#
|
|
# So arm repeatedly and keep every log: each F10 opens a new numbered file and
|
|
# CLOSES the previous one (which stays on disk, complete). Re-arming every few
|
|
# seconds through the boot therefore tiles the whole approach to the title, and
|
|
# whichever file happens to straddle the build contains it. Stop re-arming the
|
|
# instant the title is classified, so a press cannot land mid-build and abandon
|
|
# the one file that matters.
|
|
#
|
|
# NO pad input at all. Ⓐ during the boot has ended a run on a permanent black
|
|
# screen (docs/re/canary-scripted-input-traps.md), and nothing here needs it.
|
|
#
|
|
# Usage: screen_build_capture.sh [out_dir] [timeout_s]
|
|
# FRAMES= frames per capture window (default 1200 ~ 20 s at 60 Hz)
|
|
# MAXDRAWS= hard stop per capture (default 80000)
|
|
# REARM= seconds between F10 presses (default 10)
