 Hi,

 the problem depends on the brittle implementation of the -x/-y and
 filtering interaction logic.
 Workaround: use -vf scale=504:376

 I suggest two solutions to remove -x and -y (and the maintainance burdom)
 in favor of -vf scale=w:h, and make docs and code points to -vf scale.

 Would you consider acceptable this solution?
