Description

I love the way MPlayer renders .sub subtitles, it beats every other player on the Mac at this moment. It would be great to be able to set the subtitles to be non-transparent.

Also, is it possible to get the quality of the .sub/.idx subtitles at the level of, say, DirectVobSub on Windows? They seem to be a lot smoother (anti-aliased?).

I couldn't find an option to make SPU/VobSub subtitles opaque. The only options available concern placing and anti-aliasing.

Since dvd subtitles are image-based, the quality is largely dependent on the dvd. I think there's only so much possible with anti-aliasing that regular dvd subtitles will always look blocky.

The only way to get them more smooth is to apply a blurring filter. There are some more sophisticated upscaling filters available (and probably used in DirectVobSub) but the mplayer implementation doesn't do any of them:

You can enable the blurring filter with "-spuaa 20" and then adjust the blurring with "-spugauss 1" in a range from 0.0 to 3.0.

Thanks for the explanation on the upscaling.

Any chance of implementing the blurring settings in the GUI?
