hmm w=384 ? looks more like 348 ... ;) which isnt %16==0
the pp code needs luma/chroma output stride%8==0 as the code works with 8x8 
blocks, its possible to copy the right row into a buffer and work in there 
but it would slow things down, actually this right side buffereing code was 
implemented but than put under #ifdef as arpi said its no problem to keep 
output stride %16==0 (that was really long ago) i dunno if it still works

-vop expand=352:172,pp seems to fix it ...
