What did you do?

play this:
test..zip

1. After clearing all configurations in DEFAULT_SHAKA_CONFIGURATION, the problem still persists.
2. Rolling back the Shaka version to 4.16.43 does not resolve the issue.

What did you expect to happen?

It is acceptable to throw playback‑related errors; avoid ANR or out‑of‑memory crashes. Normal playback is preferred.

What actually happened?

ANR occurs immediately when testing this video, with an out‑of‑memory alert popping up after a period of waiting. The issue is 100% reproducible.

Are you planning to send a PR to add it?

Yes

I've redacted your zip file URL, which returns a 404 now.

Could you provide us with a reproduction stream instead? Thanks.
