commit 018ba6b6124f7fa112462c50969a4032cebdf479 Author: Lynne <[email protected]> AuthorDate: Sat Dec 13 02:40:43 2025 +0100 Commit: Lynne <[email protected]> CommitDate: Sat Dec 13 19:12:20 2025 +0100 vulkan_decode: do not reset the decoder when flushing The issue is that .flush gets called asynchronously, and modifies the video session state while its being used for decoding. This did not result in issues since all known vendors do not keep important state there, but its not compliant with the specs. Its not necessary to flush the decoder at all when seeking, so simply don't.
