HI, all

  I want to capture 320*240 UYVY formate video.the problem i met is that the 
capture buffer length is always 882746(768*576*2,UYVY format).i had tried to 
change the crop or v4l2_format parameters ,but it doesn't work,the system seems 
to ignore my setting.can anyone tell me a simple correct way to do it right?

thanks!
