At the begin of each Render Node `pull()`, the render job is expected to ''announce'' a maximum expected allocation requirement to the `BufferProvider`, which information is passed-on to the `LocalMemPool` to determine to which degree it can be satisfied with allocations from that local pool. Without actual empiric observation, it is impossible to determine the relevance of this step, how it should be resolved heuristically against the known contents of the pool, and how much effort to spend on that step. Thus I'll settle for the ''simplest thing that can possibly work'' — which is to check only for close matches and rather rely on additional allocations, forwarded asynchronously, assuming that the clean-up heuristics will deal with excess allocations quickly. |

Lumiera -- the video NLE for Linux ================================== Version: 0.pre.05~dev :Date: 11/2025 ************************************************************* Lumiera is a non-linear video editing and compositing tool. The Application will allow to edit footage using common multimedia formats and audio/video stream codecs. Lumiera features nondestructive editing, compositing tools, a selection of effects plugins, processing in RGB, YUV and RGB-float colour models and the ability to mix media with differing sizes and framerates. Lumiera is especially well suited for large and elaborate professional editing tasks with lots of material, several scenes, nested sequences, colour grading, 3D support, full fledged sound montage and multiple edit versions prepared in parallel. NOTE: as of 11/2025, Lumiera is in early development stage; it is not usable yet. The above describes the Lumiera project vision, the implementation of which will require many more years. Visit https://Lumiera.org and join the mailing list when interested in Lumiera planning and development. **************************************************************** Lumiera pre-Alpha Versions -------------------------- .This source tree doesn't contain a working video editing application yet. Rather, it contains the framework and technology core of the envisioned Application »Lumiera«. What we attempt to build here is innovative, and we must engage in a series of integration steps to search for suitable pathways towards our envisaged architecture. Since 2024, the integration of the Render Engine takes centre stage, in an effort to establish a steady state realtime processing and display pipeline, still relying on generated video data rather than using a library to read and playback a video file. - https://Lumiera.org/documentation/design/governance/integration.html[Integration steps] - See also https://issues.lumiera.org/roadmap[Project roadmap] Build Requirements ------------------ For building Lumiera, you'll need: * C++23 compiler GCC >=14 (Clang fails atm) * Git Version management system * https://www.scons.org/[SCons build system] * https://www.boost.org/[Boost libraries] * https://github.com/bplaum/gavl[GAVL library] * https://www.alsa-project.org/[ALSA (libasound2-dev)] * https://nobug.pipapo.org/[NoBug library] * https://gtkmm.gnome.org/en/[gtkmm] * https://cgit.freedesktop.org/xorg/lib/libXv[libXv] * https://wiki.gnome.org/Projects/LibRsvg[lib rSVG] * https://git.lumiera.org/gitweb?p=debian/gdl;a=summary[lib GDL] * https://git.lumiera.org/gitweb?p=debian/gdlmm;a=summary[GDL-mm bindings] Further information: * Online documentation at https://Lumiera.org/download.html[Build and install]. * Documentation is also available in-tree in 'doc/user/tutorials/building.txt' * Source code can be retrieved with `git clone git://git.lumiera.org/LUMIERA` Debian Package -------------- Hermann Vosseler (aka Ichthyo) maintains a *Debian* packaging of the source tree - the package definition can be pulled from `git://git.lumiera.org/debian/lumiera/` - the package can be built by `git-buildpackage`
