I'm trying to use XvShmCreateImage() to create a YV12 image of size 2880x1152. The call succeeds but the data_size field in the returned XvImage is smaller than the required 2880x1152x3/2 bytes. Looking at the value of XvImage->data_size I guess my XvImage has been cropped to 2048x1152.
Is this down to the driver (ATI r128 in this case) or a another software layer in libXv? Is this the correct behaviour from XvShmCreateImage()? Is there a workaround I can use in my application?... The way I want to use this XvImage is like this: The source is actually composed of a 4x4 grid of 720*288 YUV images The destination for XvShmPutImage is always a 720x576 window The source for XvShmPutImage is a subset of the grid (1, 2x2, 3x3, or 4x4). Anybody help me out TIA Paul Robertson _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
