commit dec1ffb86d8aa0bad663308fe129253287fba259 Author: Niklas Haas <[email protected]> AuthorDate: Tue Aug 11 17:30:21 2026 +0200 Commit: Niklas Haas <[email protected]> CommitDate: Mon Aug 31 10:56:08 2026 +0000 avcodec/j2kenc: fix edge case when packet ends on 0xFF ISO/IEC 15444-1:2002 (E), Annex B.10.1 "Bit-stuffing routine": > The last byte in the packet header shall not be an 0xFF value (thus the > single zero bit stuffed after a byte with 0xFF must be included even if > the 0xFF would otherwise have been the last byte). This matches the behavior seen in the jpeg2000 decoder (jpeg2000_flush), and the behavior of openjpeg.
