Subject: [FFmpeg-devel] [PATCH 0/2] Fix Nikon HEIF decoding error
Date: Wed, 16 Jul 2025 19:30:00 -0700
Message-ID: <20250717023057.678-1-erj@erj.cc> (raw)
This patch set was motivated by ffmpeg being unable to open .HIF files
from a Nikon Z6 III camera because it would always fail with an error
involving thumbnails; probably due to them including three.
With these changes, ffprobe/ffmpeg will no longer
error out on those types of files.
I ran "make fate" on these commits, and was able to extract the thumbnail
streams and encode them as pngs or jpegs, too.
