Sorry , I forgot a few items : Save a snap shot or continously save to save in either rgb or yuv format. Not sure about continously saving to a file , we could implement loadable modules so that we can save the files in h.263, h.261, rgb, or yuv formats. With respect to saving snapshots check first the highest snapshot number and continue from there. Too many times have I deleted cool shots because "tv" always starts taking snapshots from img000.jpg and up. So lets gather volunteers and a complete list of reguirements. >From The Desk Of Luigi Rizzo : > > Here is a great opportunity to contribute 8) > > > > Requirements: > > > > Support for the following : > > o color depths: 8, 15, 16, 32 > > I have 16bit already working, and 8-bit almost ready.

I grab the "tv" window and streach horizontally or vertically and "tv" will issue the appropiate geometry call to the video capture driver. > > o direct output to vga frame buffer > > Amancio, you did have this, didn't you ? What kind of X support does it > need ? Yes, I did this and is more of a coordination effort with Jim Lowe and me so that the meteor driver compiles the appropiate code and ioctls to support PCI to PCI. On the X server side of things we just need a handle to acquire the virtual address of the frame buffer. Such a call already exists for XFree86 however there is no counterpart for Xinside's X server. This feature I consider very important cause it is bloodly fast 8) Enjoy, Amancio
