You would want to use GStreamer for this; it's the gtk of audio/video processing. GStreamer can read video data using video4linux directly. It can convert between almost any color spaces and it can render into GTK applications, optionally using an XVideo overlay (which are hardware accelerated and mostly support YUV color spaces directly). The beauty of GStreamer is that your application doesn't have to care about the details. Depending on the capture hardware (for the video4linux end) and the graphics card (on the rendering end), many different combinations of formats are possible. The color space converter of GStreamer can mediate between these two ends in a transparent way, which makes writing such applications very simple once you get the hang of it. For more information, see: http://gstreamer.freedesktop.org/ There is lots of documentation and example code, as well as an active and helpful mailing list and IRC channel. -- Regards, René Stadler _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
