how can i create a yuv(.yuv)file,4:2:0,is there any codec for this

ffmpeg is a way (theoretically), but even as late as r8047, it is fraught with a ton of non monotone timestamp errors in every sample I have tried and no real solution in sight. As a result, the resultant yuv file isn't recognized by Avisynth because of a YUV4MPEG2 header error. Sorry, I wasn't of much help, I am on the same boat too. ffmpeg mailing list is a good place to start if you are interested.

which is the yuv,4:2:0 colorspace i need (YV12 or I420 or YUY2,..).i need this becoz i am testing the h264 algo.the color space specified is yuv 4:2:0.

YV12 and I420 are both 4:2:0. Try I420 first, then if the colors are messed up try YV12.
