I've got a decoder that selects between composite/s-video/tuner sources, and also has a CCIR port for a data source coming from an MPEG decoder. This seems to be a natural extension for VIDIOC_CC_S_VIDEO_MUX/VIDIOC_CC_G_VIDEO_MUX, but that doesn't seem to have any natural categories for an MPEG stream. How should this be implemented? Thanks, Chris
