FuriCam

An enhanced camera app for FuriPhone, built with Qt6/QML/C++.

Based on furios-camera by FuriLabs.

I decided not to do an obvious fork and rename it since these changes will most likely never be upstreamed anyway. Not that I dont want that but since Im not a developer all I do is AI generated and I assume they wouldnt want that which is understandable.

Enhancements so far

• HDR Photography (uses Mertens fusion with OpenCV)
• Added option to adjust resolution (megapixel)
• Added option to increase jpeg compression
• Added 3x3 grid
• Added level indicator
• Added zoom slider
• Added Pro Mode (allows for manual ISO and Shutter speed adjustment)
• Added RAW (DNG) output
• Video output is now of reasonable file size (MJPEG --> H.264)
• Video output has adjustable bitrate to further adjust quality or storage savings
• Added different video resolutions to choose
• Added post processing options (RGB channels and saturation) - red was slightly reduced by default due to the FLX1s but does not seem to be an issue anymore
• Switching between photo and video mode also switches aspect ratio now
• Major improvements to the built-in gallery: Double tap to zoom, smooth swiping between pictures, etc.
• Pixel-art filters (was requested)

To be improved

• Manual focus (does not seem to be possible, on the FLX1s at least)
• Different media player backend in the built-in gallery because video playback is a little choppy even at 1080p
• Maybe different HDR approach as OpenCV is very memory intensive but results are pretty solid overall
• DRO (maybe, spollards fork already includes it but it made everything very washed out so i left it out)
• Feel free to request something if there is anything missing

Building

Builds natively on the FuriPhone (Debian Forky arm64) - no distrobox needed.

Note - Qt6 dev packages vs. the GLES Qt on FuriOS

On current FuriOS the GUI stack is the GLES Qt build (libqt6gui6-gles), which only Provides: libqt6gui6 (= …dfsg-12) and Conflicts: the plain libqt6gui6. But qt6-base-dev hard-depends on the exact matching libqt6gui6 (= …dfsg-15), so a normal apt install qt6-base-dev … refuses.

Work around it by downloading the dev packages and force-installing them (the real GLES libs serve at runtime - only the headers/CMake files are needed):

mkdir -p /tmp/qt6debs && cd /tmp/qt6debs
apt-get download qt6-base-dev qt6-declarative-dev qt6-multimedia-dev
sudo dpkg -i --force-depends /tmp/qt6debs/*.deb

This leaves apt with one "unmet dependency" for qt6-base-dev - harmless for building, but every later apt command will complain. To restore a clean apt state (e.g. before testing a package upgrade), remove them again:

sudo dpkg --remove --force-depends qt6-base-dev qt6-declarative-dev qt6-multimedia-dev

Build

mkdir build
cd build
cmake ..
make -j$(nproc)

Runtime dependencies

sudo apt install qml6-module-qtmultimedia \
                 libqt6multimedia6 \
                 qml6-module-qtquick \
                 qml6-module-qtquick-controls \
                 qml6-module-qtquick-window \

                 qml6-module-qtsensors \
                 qt6-svg-plugins \
                 mkvtoolnix \
                 ffmpeg \
                 libqt6svg6 \
                 libgstreamer1.0-0 \
                 gstreamer1.0-droid \
                 gstreamer1.0-plugins-good \
                 gstreamer1.0-plugins-base \
                 libzxing3

Building the .deb

With the Qt6 dev headers force-installed as above:

dpkg-buildpackage -d -us -uc -b

The -d flag skips build-dependency checks - required here both because qt6-base-dev's libqt6gui6 dependency is unsatisfiable against the GLES Qt (see the note above) and because libhybris-common.so.1 is present at runtime but lacks a proper dev package. dpkg-shlibdeps still resolves the runtime Depends correctly (it picks libqt6gui6-gles), so the resulting .deb installs and upgrades cleanly via apt.

AI Disclosure

This application was built with the assistance of AI (Mostly Claude, DeepSeek and Kimi inside Copilot CLI).
