Chrome draws no frames for a hidden page, so the scene stopped asking
for its videos. The sweeper of the VideoLibrary kept running and
dropped every player after 2 s. Back in the window, the video started
over, and Pixi warned that a texture source was destroyed while still
bound to a shader.
- The sweeper skips a hidden page. The time hidden does not count as
idle, the 2 s start once the page is shown again.
- A dropped player only unloads its video source instead of destroying
it. A shader that still holds the source no longer warns.
- CI serves videos through a new router for php -S. The built-in
server answers no Range requests, so Chrome could not seek. e2e 66
had 4 red checks in the suite job of d48f174 because of it. nginx on
stein2 hid this.
Tests:
- Unit video-library.test.ts (new): 3 tests
- e2e 66 (atx): ALL PASSED, 18 checks
- Router checked with curl: 206 with the right bytes
- Counter-check: the old sweep fails both hidden-page tests
