>a K6-200, 66MHz SDRAM, a PCI bus and a generic BT878 card? Which is most >likely to be the bottleneck? Does the BT878 use DMA? Yes, BT878 uses DMA, depending on how you capture. If you read from the card it may or may not, but if you use the streaming interface (the mmaped memory) it definitely will. Also, look for formats with the fewest bits per pixel. (you wanted fast, right? minimize you memcpy's) rgb24 uses 24, yuv420 uses 12 (this is what a lot of compression programs use) and I thing uyuv uses 16, etc. If you print out the image formats from the enum formats (at least for v4l2) then you will get a lot of information. Also check out the section of the v4l2 API about pixel formats. >If anyone could >just *name* a no-nonsense X windows setup I'll install it and figure it out. >* What is a really lightweight X windows manager/toolkit combo that will >work with V4L2? >* I can get by without Gnome and KDE can't I? Maybe you can. I use WindowManager (definitely light, although fvwm or perhaps twm would be lighter. Without gnome and kde you may have to write you own viewing utility. >3. >Can anyone recommend a good IDE? At this stage I am using 'nano' and a make >file.

Just be careful about installing gnome or KDE. Also watch what services (network client/network server, I don't remember the heading) you install. Don't install any window managers except the one you think you will use. >My plan is to upgrade and reinstall my system for the last time. Then I >hope I can spend more time working and less reading!
