Anyway, good work, it's a very useful tool =b
What's the best 4:3 ratio for mplayer? Presumably you'd want the height to be maximum, and the width to be minimum. However, the amount of cropping can be reduced (it's the @cropLimit definition at the start of the code). Does mplayer need the multiple-of-16 size that the built-in video player does?

Would it be better in general if the width declared in the preset was ignored for 4:3 stuff (i.e where it's taller than wider) in the original aspect?

To be honest, actually I noticed some framedrops on complicated panning scenes with this preset, but it still looks quite acceptable or even good. And we still have potential for quite a noticeable performance improvement by using YUV colorspace directly. Also video decoder from ffmpeg library that is used in mplayer can be probably better optimized for arm
Cool, I'll leave its bitrates as-is for the moment, but they can be tweaked when new versions come out.

Cheers,

Andrew
