I'mrying to output videos with a constant height but with the width changing based onhe input aspect ratio. Also it needs to always map toquare pixels as the destination player does not support non-square pixels. forxample, if the input file is 720x480 16:9 the output should be 656x368. i can't get ito work, though... no matter what i do it mencoder always retainshe pixel aspect ratio of the original file, so it outputs the videot 560x368. mplayer plays it fine but the destination player is adobe flash, which doesn't. what filter chain do i needo do what i want? -jsd-
