commit 532486e0a51c47c94496bc0bcc2859fb14b2a808 Author: Rafael Henrique Gonçalves de Oliveira <[email protected]> AuthorDate: Fri Oct 23 20:41:57 2026 -0300 Commit: Timo Rothenpieler <[email protected]> CommitDate: Sat Oct 24 20:55:29 2026 +0000 avfilter/vsrc_gfxcapture: use fresh callback state for each WGC thread call run_on_wgc_thread() reused one callback state for every call and reset its cancel flag each time. A callback that timed out while still queued could then run after the next call's reset, through references to the earlier caller's stack. Each call now gets its own state, which the queued callback keeps alive.
