commit 696d754bba149239b33df9bd287cc060e24a8eba Author: Kacper Michajłow <[email protected]> AuthorDate: Tue Sep 22 18:34:17 2026 +0200 Commit: Kacper Michajłow <[email protected]> CommitDate: Tue Sep 29 22:39:09 2026 +0200 avutil/tests/error: print only the FFmpeg-defined codes The errno descriptions come from the C library where strerror_r() is available and from the built-in table elsewhere, so the output differed between platforms and could not be compared against a reference. Look the errno codes up without printing them and fail when any code is not found.
