Hi Pete, The next issue to solve is auto-exposure/white balance (AEWB). For this, Laurent has put together a nice example application in a project called omap3-isp-live [1]. This project builds two programs, 'live' and 'snapshot'. For my purposes, I want to have live streaming video. 'live' makes use of a local display and was not able to get this running using an HDMI display (on Beagleboard-xM). I modified the program to write the buffer data to stdout in the same way as yavta does, and use netcat to pipe the live data over a network socket to mplayer. This provides the video live using a network stream. This application wants allocate display buffers that are larger than coded into the kernel, so I had to modify the kernel to increase the buffer size. I'm still working on this and things are in a bit of disarray. I don't have suitable patches just yet, otherwise I would share them.
