[libdv-dev] Re: simpledv interface to libdv

[Charles 'B. K. <kr...@cs...>]

Hi there.  I have one comment so far on your simpledv api.  

You may want to reconsider the direct use of GdkPixmaps in DVFile.  I
think that the natural output format of the decoder should be YUV, not
an RGB format like the GdkPixmap.  When HW assist for YUV color
conversion and scaling are available, they make a massive difference
in performance.

There are currently two patches in the libdv project page on
sourceforge.net which implement YUV rendering.  One uses the Xv
extension directly, while the other uses the SDL library as a shim
over Xv (when it is present).  Another as yet unimplemented approach
is to use OpenGL textures.
