Reply To: scaling filters


Currently, the filters are only enabled in line2x or line3x mode and if it’s one of the optimized 240P resolutions. That was to simplify the check for a H_TOTAL – H_SYNCLEN that’s under 1024 pixels so the linebuffer isn’t overrun. 480p and some of the other resolutions should work by just enabling the filter for them. Some of the higher resolutions may work with some changes to drop useless samples. I’ll give a try this weekend and see what happens.

Not sure how good 480i will look with filters given that it’s comparing every other row.

I haven’t solved the flickering pixel problem. It may be possible with a frame buffer, but there’s no room for one.
