Package: gthumb Version: 3:3.12.2-3+b1 Severity: normal gthumb appears to ignore quicktime video orientation on playback, causing the playback to have the wrong orientation.
I have many videos that were recorded on an iphone in standard letterbox format, but that play back upside-down when viewed with gthumb. VLC and other players seem to play them back just fine. ExifTool reports these tags for these videos: "Composite:Rotation": 180 "QuickTime:MatrixStructure": "1 0 0 0 1 0 0 0 1" -- System Information: Debian Release: 12.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.1.0-14-amd64 (SMP w/4 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages gthumb depends on: ii gsettings-desktop-schemas 43.0-1 ii gthumb-data 3:3.12.2-3 ii libbrasero-media3-1 3.12.3-2 ii libc6 2.36-9+deb12u3 ii libcairo2 1.16.0-7 ii libchamplain-0.12-0 0.12.20-1+b1 ii libchamplain-gtk-0.12-0 0.12.20-1+b1 ii libclutter-1.0-0 1.26.4+dfsg-4 ii libclutter-gtk-1.0-0 1.8.4-4+b1 ii libcolord2 1.4.6-2.2 ii libexiv2-27 0.27.6-1 ii libgcc-s1 12.2.0-14 ii libgdk-pixbuf-2.0-0 2.42.10+dfsg-1+b1 ii libgl1-mesa-dri 22.3.6-1+deb12u1 ii libglib2.0-0 2.74.6-2 ii libgstreamer-plugins-base1.0-0 1.22.0-3+deb12u1 ii libgstreamer1.0-0 1.22.0-2 ii libgtk-3-0 3.24.38-2~deb12u1 ii libheif1 1.15.1-1 ii libjpeg62-turbo 1:2.1.5-2 ii liblcms2-2 2.14-2 ii libpango-1.0-0 1.50.12+ds-1 ii libpangocairo-1.0-0 1.50.12+ds-1 ii libpng16-16 1.6.39-2 ii libraw20 0.20.2-2.1 ii librsvg2-2 2.54.7+dfsg-1~deb12u1 ii libsecret-1-0 0.20.5-3 ii libsoup2.4-1 2.74.3-1 ii libstdc++6 12.2.0-14 ii libtiff6 4.5.0-6+deb12u1 ii libwebkit2gtk-4.0-37 2.42.4-1~deb12u1 ii libwebp7 1.2.4-0.2+deb12u1 ii libx11-6 2:1.8.4-2+deb12u2 ii zlib1g 1:1.2.13.dfsg-1 Versions of packages gthumb recommends: ii libgphoto2-6 2.5.30-1 ii libgphoto2-port12 2.5.30-1 gthumb suggests no packages. -- debconf-show failed
