KDENLIVE_RENDER(1)					   Render program for Kdenlive. 					KDENLIVE_RENDER(1)

NAME

       kdenlive_render - Render program for Kdenlive.

SYNOPSIS

       kdenlive_render [-erase] [in=pos] [out=pos] [render] [profile] [rendermodule] [player] [src] [dest] [[arg1] [arg2] ...]

DESCRIPTION

       Render  program	for Kdenlive. Renders kdenlive project detached from Kdenlive, while providing feedback through kuiserver. This program is
       not meant to be called directly by users, but is called from Kdenlive, when a rendering process is started.

OPTIONS

   Options:
       -erase If present, src file will be erased after rendering

       in=pos Start rendering at frame pos

       out=pos
	      End rendering at frame pos

       render Path to MLT melt render program

       profile
	      The MLT video profile

       rendermodule
	      The MLT consumer used for rendering, usually it is avformat

       player Path to video player to play when rendering is over, use '-' to disable playing

       src    Source file - usually MLT playlist

       dest   Destination file

       args   Space separated libavformat arguments

ENVIRONMENT

       KDENLIVE_RENDER_LOG
	      If $KDENLIVE_RENDER_LOG is set, a log will be written to /tmp/kdenlive_render.log.XXXXXXXX,  that  contains  information	about  the
	      result of calling melt, ffmpeg, etc. This can be used for debugging.

GLXCOPYCONTEXT()														  GLXCOPYCONTEXT()

NAME

       glXCopyContext - copy state from one rendering context to another

C SPECIFICATION

       void glXCopyContext( Display *dpy,
			    GLXContext src,
			    GLXContext dst,
			    unsigned long mask )

       delim $$

PARAMETERS

       dpy   Specifies the connection to the X server.

       src   Specifies the source context.

       dst   Specifies the destination context.

       mask  Specifies which portions of src state are to be copied to dst.

DESCRIPTION

       glXCopyContext copies selected groups of state variables from src to dst.  mask indicates which groups of state variables are to be copied.
       mask contains the bitwise OR of the same symbolic names that are passed to the GL  command  glPushAttrib.   The	single	symbolic  constant
       GL_ALL_ATTRIB_BITS can be used to copy the maximum possible portion of rendering state.

       The  copy  can be done only if the renderers named by src and dst share an address space.  Two rendering contexts share an address space if
       both are nondirect using the same server, or if both are direct and owned by a single process.  Note that in the nondirect case it  is  not
       necessary for the calling threads to share an address space, only for their related rendering contexts to share an address space.

       Not  all values for GL state can be copied.  For example, pixel pack and unpack state, render mode state, and select and feedback state are
       not copied.  The state that can be copied is exactly the state that is manipulated by the GL command
       glPushAttrib.

       An implicit glFlush is done by glXCopyContext if src is the current context for the calling thread.

NOTES

       A process is a single execution environment, implemented in a single address space, consisting of one or more threads.

       A thread is one of a set of subprocesses that share a single address space, but maintain separate program counters, stack spaces, and other
       related global data.  A thread that is the only member of its subprocess group is equivalent to a process.

ERRORS

       BadMatch is generated if rendering contexts src and dst do not share an address space or were not created with respect to the same screen.

       BadAccess is generated if dst is current to any thread (including the calling thread) at the time glXCopyContext is called.

       GLXBadCurrentWindow is generated if src is the current context and the current drawable is a window that is no longer valid.

       GLXBadContext is generated if either src or dst is not a valid GLX context.
