Thanks heiko,Hi Sandy, Am Dienstag, 17. April 2018, 12:15:07 CEST schrieb Sandy Huang:When video width is bigger than 3840 the linebuffer mode should be LB_YUV_3840X5.Can you explain that a bit better? I.e. when looking at the code, the very first check is width > 2560. So it seems your change targets some YUV mode with width > 3840 which should be mentioned in the commit message, so people like me don't scratch their head in confusion ;-) Similarly that check is actually width > 1280 to set LB_YUV_3840X5, so I guess you're actually wanting any YUV mode bigger than 1280px should use LB_YUV_3840X5? Heiko I will make more description for this path at next version.
