Following on from the suggestion to use a filter I have a question if anyone can help.

In my test im looking at the drawbox filter as a refernece but ive got this problem.

ffmpeg -i test.ts -vf drawbox:10:10:710:100:red -f mpegts -y a.ts

Works as it should

ffmpeg -i test.ts -vf drawbox:10:10:710:100:red -s 352x288 -f mpegts -y a.ts

Works but the box is drawn off screen, so my question is

1. How do i get the filter to work BEFORE the resize? is there a filter that does this?
