Additionaly it has to be ensured that memory usage is low enough and performance acceptable. Next step would be a mechanism to provide proxy of the clips for not high-end machines. The focus of this task is to implement OpenCine module, which re-uses OCcore lib to provide video data through FUSE (Filesystem in Userspace) as dummy AVI file. **Goals:** - Create a frame server module using libfuse and attach OCcore as data provider - Extend OCcore for providing consequent frames, so the video is playable in a video player - Add user interface to control frame server settings, like frames per second (FPS) or de-Bayering processor - Add Dokany, to be able to run frame server on Windows and adjust CMake scripts accordingly, for consistent build process without user intervention, like on Linux **Prerequisites:** You are expected to have working knowledge of (most of) the following: -- C and C++ and their coding standards (Any IDE) -- CMake -- FUSE (file in user space for linux) -- RAW12, MLV, AVI, BMP, Adobe DNG file formats -- Qt 5.10 and higher (for creating the User Interface) -- Dynamic libraries (and their linking - see T872 for appropriate task that tests this) -- Git based workflow, Github account and Git client -- Debayering methods and their implementation in OpenCine (T872 tests this) -- Basic image processing **Difficulty level:** Medium **Mentors:** Andrej, Supragya **Links** - Frameserver: https://en.wikipedia.org/wiki/Frameserver - Open Cine Overview: https://www.apertus.org/opencine - Wiki: https://wiki.apertus.org/index.php/OpenCine - FUSE: https://de.wikipedia.org/wiki/Filesystem_in_Userspace - libfuse: https://github.com/libfuse/libfuse - Dokany: https://github.com/dokan-dev/dokany - MLV file format: https://www.magiclantern.fm/forum/index.php?topic=7122.0 - DNG file format: https://helpx.adobe.com/in/photoshop/digital-negative.html - Frame server prototype (FUSE / AVI): https://github.com/BAndiT1983/OC_FrameServer/tree/dev To get in touch with any mentor check the [[ https://www.apertus.org/GSoC-2019-Mentor-Contact-List | Mentor Contact List]].

Most approaches use FUSE (Filesystem in Userspace) to intercept call to such a file and to provide data to the calling video player/editor.
