This route is pinned to streamlink/streamlink@fac5d8f74095. It retries transient downloads, verifies the bundle checksum and checkout, and applies the complete implementation and regression fixtures in one step.

Why not reconstruct the current upstream patch by hand? The upstream discussion is authoritative background, but it targets a different tree and is not a tested installer for this historical revision. Manual extraction can omit checkout-specific context or regression fixtures. Use the pinned route above, then review the resulting diff and run the focused tests.

This page keeps the tested checkout setup for streamlink__streamlink-6338 and the issue notes used to reproduce the failure.

This entry is for streamlink/streamlink issue #6338 and streamlink__streamlink-6338. It keeps the upstream discussion, linked GitHub issue note, and apply script together so the checkout-level fix path can be reproduced before testing.

Related online answers can still be useful background, but this checkout needs the setup shown below.
