The WSS information described in the wikipedia page refers to additional bits encoded in the frame - in the vertical blanking interval. This is an example of VBI - which the driver doesn't currently support unfortunately. WSS information in the mpeg stream is a different sort of animal, but the mpeg encoder will include that as part of the byte stream. By default it emits "4:3", but you can use a sysfs control to adjust it. That's the video_aspect control I had mentioned earlier. This control should also be available in the normal V4L API via the mpeg-specific V4l extended controls. -Mike -- Mike Isely isely @ pobox (dot) com PGP: 03 54 43 4D 75 E5 CC 92 71 16 01 E2 B5 F5 C1 E8 _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
