explanation: we use pthread_once to define a mutex type descriptor, used to define some of our mutexes as recursive mutexes. Now, pthread_once relies on a counter stored in a given location; we used a non-exported global var for this counter. Unfortunately this ties the mutex initialisation to the static initialisation of the compilation unit holding this counter variable. Theoretically it would be possible (we never observed such an incident) that, during static initialisation, a singleton was brought up, which requires a class-scoped lock, implemented as recursive mutex. And it would be possible for this singleton locking to happen prior to initialisation of the mentioned counter variable. As a fix, I've moved the counter varialbe into a function scoped static variable, since that is guaranteed by the C++ runtime system to be initialised at first usage of the function, irrespective of the initialisation order of the enclosing compilation units |

Lumiera -- the video NLE for Linux ==================================== ************************************************************* Lumiera is a nonlinear video editing and compositing tool. It understands some of the common multimedia formats (quicktime, avi, ogg) and audio/video compression codecs (divx, xvid, mpeg1/2/4, ...) It features non-destructive editing, compositing tools, a selection of effects plugins, processing in RGB, YUV and RGB-float colormodels and the ability to mix media with differing sizes and framerates. More Informations at http://lumiera.org/[Lumiera.org] **************************************************************** Lumiera pre-Alpha Versions -------------------------- **This source tree doesn't yet contain a working video editing application** + Rather, it contains the framework and technology core of the envisioned Application ``Lumiera''. As of _7/2007_:: we start here with the backend and render engine modules together with some unit tests. You should find a wiki with detailed design considerations and developer documentation and a UML model (usable with BOUML 2.29) in the sibling directories. As of _2/2008_:: the project has been separated completely from his ancestor ``Cinelerra'' The Community, which is largely identical to the Cinelerra-CV community, choose the new project name ``Lumiera''. The basic project infrastructure is up and running, and work on the new codebase is going on continuosely. We can show nothing but a running test suite for some time to come. As of _1/2011_:: the project has created and documented a fairly consistent design, partially already coded up -- starting from the technical foundations and working up. The code base is approaching 100k LOC. Roughly half of this is testcode. The Application can be installed and started to bring up an GTK GUI outline, but the GUI is very preliminary and not connected to core functionality. The video processing pipeline is still not complete. See http://issues.lumiera.org/roadmap[Project roadmap] Build Requirements ------------------ For building Lumiera, you'll need: - GNU C/C++ compiler (Version > 4.3) - Git Version management system - http://www.boost.org/[Boost libraries] - http://gmerlin.sourceforge.net/[GAVL library] - http://lumiera.org/nobug_manual.html[NoBug library] - GTK\-- - Cairo and Glade libraries - X libraries - http://scons.org[SCons] or Autotools build system See the online documentation at http://lumiera.org/Lumiera/NewbiesTutorials or the local Copy of this page in the file INSTALL 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/lumiera/debian+ - the package can be built by +git-buildpackage+
