      • Does anyone know of an official list of features and limitations for the different Vertex Shader and Pixel Shader versions (1.1, 2.0, 3.0, etc) I couldn't find anything on the Microsoft or nVidia web sites or on the web. I don't even know for sure who governs these standards.

      • I use a open source codec/video library (libavcodec). This lib exposes the video frames as 24_bit RGB bitmaps in memory. All I want to do now, is displaying those frames in a window as fast as possible. I tried a very naive approach: for ( unsigned int i = 0 ; i < Framenumber; i++ ) { Load->get_nth_frame( ID, i , RGBFrame ); DXDev->BeginScene(); Backbuffer->LockRect( &

      • Hi I have been reading through the forum for hours now and there is something I do not quite understand: Any class that is required for readers comes from Microsoft.Xna.Framework.Content.Pipeline. This library is not available for the Xbox 360, thus leading me to the conclusion that it is currently not possible to write a custom ContentTypeReader for the Xbox 360. Is that correct My other problem

More details on my blog: http://codecube.net/item.asp cc_ItemID=358 The way it works is that you add an AVI to your GSE project, load it up using the ContentManager, and render it (using SpriteBatch for example). I've tested it pretty thoroughly, however, I'd like the teeming masses to t
