Subject: [FFmpeg-devel] [PATCH 2/2] libavformat: Enable jpeg streams in HEIF MOVContext
Date: Wed, 16 Jul 2025 19:30:02 -0700
Message-ID: <20250717023057.678-3-erj@erj.cc> (raw)
In-Reply-To: <20250717023057.678-1-erj@erj.cc>

Nikon HEIFs from a camera or NX studio include a small jpeg thumbnail in addition to
the expected HEVC thumbnails; allowing jpegs allows all thumbnails to
have an associated stream for Nikon HEIF files.

With this, Nikon HEIFs can finally be decoded without failing and the
thumbnails can be extracted into their own files.
