Subject: [FFmpeg-devel] [PATCH] libavcodec/hcadec: fix header parsing after 'comp' section
Date: Tue, 17 Jun 2025 11:05:55 -0700
Message-ID: <20250617180625.23604-1-roslypav@gmail.com> (raw)
Need to skip 2 more bytes because comp sections are 12 bytes long.
Fixes decryption since ciph_type is now being set.
