Where to set the pixel format of the video output overlay? Video (input) overlays don't need it to be set, because they adapt to the frame buffer or override the video signal. For v4l3 maybe some parts of video outputs should be moved to video output overlays. IMHO video outputs should define only things like tv standard, audio output, modulation, cropping rectangle, etc. and all rendering should be done via video output overlays (f.ex. one for MPEG and one for OSD). Then we wouldn't need that V4L2_CAP_VIDEO_OUTPUT_POS kludge and could use v4l2_window instead (which should be relative to the cropping rectangle of the video output). Video output overlays not associated with a video output should be able to do what vidix has tried to do: Provide access to the video scalers on graphics cards.
