Ok.  Bottom-up is something weird and it seems to come from MS windows. But a mutli-platform framework required some modularity (do not know if it is the exact word !). That's the big point isn't ! Specify the direction in the caps, as you said, could be a first step. Thx a lot.

We don't have a way to specify the direction in the caps currently, although it could be added... which would mean adding support of that caps in all plugins that handle raw video (and that's LOT of plugins).     Edward On Wed, 2008-04-09 at 10:59 +0200, Julien Isorce wrote: > Hi, > > From gstreamer video source elements, is there a way to choose > top-down or bottom-up DIBs (device-independent bitmaps) like shown in > this article: > <a href="http://msdn2.microsoft.com/en-us/library/ms787796(VS.85).aspx">http://msdn2.microsoft.com/en-us/library/ms787796(VS.85).aspx</a> > ? > > Sincerely > > Julien > ------------------------------------------------------------------------- > This SF.net email is sponsored by the 2008 JavaOne(SM) Conference > Don't miss this year's exciting event.
