The controls ctl_crop_height and ctl_crop_top would allow to remove the black bars. This cropping is done by the analog decoder. A typical PAL/625 letterbox frame is then 720x432 dot with an image aspect ratio of 20/11 or 16/9. Alas, this capability is not in the kernel and the patches need to be ported to 2.6.29. Here mplayer images 720x432 as 16/9 if the mpeg stream is tagged with a 4/3 aspect ratio. Its logic is, with rd the dot aspect ratio, tag=4/3 -> rd=16/15 -> ri=rd*Nh/Nv=16/15*720/432=16/9 and e.g. tag=16/9 -> rd=64/45 -> ri=rd*Nh/Nv=64/45*720/576=16/9 for a true 720x576 anamorphic frame. You might try $ mplayer -vo xv -ao alsa -vf crop=720:432:-1:-1 file.mpg or for an rd=12/11 pal-plus capture $ mplayer -vo xv -ao alsa -aspect 15/11 -vf crop=720:432:-1:-1 file.mpg assuming 720x576 dot files. _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
