It doesn't appear to be needed since there are no multiplane > (really: multibuffer) pixelformats defined. The driver support NV12/21 and NV16/61 as output pixel formats (along with single plane YUYV). NV* formats are semi-planar, as luma is stored in one buffer, while chrominances are stored together in a different one. Am I wrong? > > > > Regards, Thanks j > > Hans
