A cut between two videos flashed white: the sprite switched on had
no picture yet, because its player only opened then or had been
dropped meanwhile. A driven video now waits muted at its time while
its sprite is off, in the editor and in a run.
- A disabled sprite with Video clock Driven asks for its player
without drawing it. A Free video still opens when shown.
- A run's draw list keeps disabled driven sprites, marked as off.
Before, collectWorldItems dropped every disabled object, so the
game view never held a player for them.
- VideoLibrary.wear() counts as asking. The sweeper dropped a held
player after 2 to 4 s and it was loading again at the cut.
- The speed of the asked time is read over a window that grows to
500 ms. Over 100 ms one 1/60 s step more or less read as 17 % off,
the playback rate jumped and the sound dropped out.
- A stream feeds every packet it has loaded to the decoder at once
and waits once. One round trip per 20 ms packet let the decoder
fall behind on a busy main thread, which made e2e 34 flaky in CI.
Tests:
- Unit streaming, video-library, video-follow: green, 4 new
- e2e 34 + 66 (atx): ALL PASSED, stream skipped 0, 66m new
- e2e 66 (atx), two runs: ALL PASSED, 25 checks, 66n new
- Gate (atx): CHECK EXIT 0, 297 files, 4557 tests
- Counter-checks: without the draw list fix 66n finds no player,
without the wear() fix and with the old speed reading the new
unit tests turn red

A sound was decoded whole as soon as the project opened, in the editor
and in a released game: five minutes of stereo held some 115 MB for as
long as the page was open. A sound with Stream on now plays from a copy
as Opus in Ogg, fetched a piece at a time and decoded a few seconds
ahead by WebCodecs, so a game holds a few megabytes for it.
- The Stream switch is a row of the sound, off by default. The Sound
tab suggests it from a minute on and says how far the copy has got.
- StreamKeeper makes the copies in the browser, a moment after the
last change, one at a time: the sound's own and one per clip of its
cut, fades and Reverse baked in. A copy that is no longer wanted is
taken off and deleted once the project is saved without it.
- streamTable says which played names stream from which copy. A clip
without a fitting copy, a Sample and a Reverb impulse stay decoded.
A sound with Stream on is never decoded ahead.
- The page fetches by Range and takes the whole file from a server
that ignores it, as the CI's PHP server does. It keeps the bytes
and the first two seconds decoded, the rest goes four seconds ahead.
- A jump decodes 32 packets before the place first. Measured in
Chrome, what follows is then the same to the bit as decoding from
the start. With 4 packets it was 0.06 off.
- The stream-player on the FX worklet reads the samples at the rate
of the context along a Catmull-Rom curve. What comes late is silent
and skipped once it is there, so a clip keeps its beat.
- The opening stretch goes with the player as it is made. Sent by
message it came a few milliseconds late, and 557 samples of the
attack were lost.
- Pitch on a streamed sound is a shifter after the player, as on a
bus: the length stays and it is heard 42.7 ms late.
- Bakes of patterns and songs (#340) always stream now.
- The song timeline draws a streamed sound from its copy decoded at
8 kHz, keeping only the peaks.
Tests:
- Gate: CHECK EXIT 0, 280 files, 4312 tests (31 new: ogg +3,
stream-queue 6, streams 11, streaming 6, sound-library +5).
- e2e 34: ALL PASSED, 106 checks (7 new). Five minutes of mono,
4.8 MB as WAV, 3.6 MB as its copy: streamed the renderer grows by
5.8 MB, decoded by 69.6 MB. Offline at 48 kHz, start, loop seam and
a reversed clip are the copy decoded whole to the sample (0).
- Counter-checks red as they should be: no pre-roll, no catch-up of
late samples at the end, no opening stretch, a streamed sound
decoded ahead.
