i have read also about fastspi library...can it be used in spite of ledstream? does it the same job
LEDstream is a unique thing. The fastSPI library is for standalone Arduino projects (similar to how our own Adafruit_WS2801 library works), and there's no need or benefit to trying to integrate this with LEDstream.
i have read that ws2801 [...] has some delays (latch time) and lower freq ...can this have some troubles using ambilight clones programs? will lpd8806 perform better?
No problem at all. The difference in timing is less than one millisecond, and there are much more important bottlenecks to contend with (such as serial port speed, and most importantly how quickly the screen captures occur, that's really the main problem there).
Last, i have heard about some strings with different ICs like ldp6803, could be good enough? Can be used with ledstream or fastspi?
I wouldn't recommend LPD6803 pixels for Adalight, and we don't have a version of LEDstream for them anyway.
