960px is 960 pixels. Page flipping is actually double buffering, used on the Y axis, meaning that the framebuffer actually holds 640x480 twice, thus 640x960 pixels, and switching from one part of this bigger frame to the other to do page flipping.
You should see something like: xres = 640 px yres = 480 px xres_virtual = 640 px yres_virtual = 960 px - Maxime On 11 nov, 21:22, "Rupesh Gujare" <[EMAIL PROTECTED]> wrote: > Hi, > > On Wed, Nov 12, 2008 at 4:28 AM, mizmit1222 <[EMAIL PROTECTED]> wrote: > > > >> 622 I/EGLDisplaySurface( 441): yres_virtual = 480 px > > > Should be 960px if your frame buffer driver supports page flip, > > which SurfaceFlinger is expecting. > > I am new to this SurfaceFlinger and frame buffer, can you explain it what is > 960px ?
