commit f9418a8f5fa6c901138e1142c4b17a2af01bdbc1 Author: Kacper Michajłow <[email protected]> AuthorDate: Wed Oct 28 23:42:14 2026 +0100 Commit: Kacper Michajłow <[email protected]> CommitDate: Mon Nov 2 18:20:48 2026 +0000 fate/ac3: pipe the dexp24 and dither encodes into the decode Both GEN rules wrote an ac3 file that only one test decoded. Pipe the encode straight into the decode instead.
