Without the scaler being enabled, it is black. :) The content I was using was regular compressed mpeg-ts, so not the best for juding aesthetic quality. We'd have to render some test geometry, such as testdisplay to be sure. (testplanes? ;) The docs do suggest that we disable the scaler to save power, so probably best if we keep the code as is. -Chris -- Chris Wilson, Intel Open Source Technology Centre
