Easily Switch Aspect Ratios in MPlayer

Wouldn’t you like to switch aspect ratios in MPlayer? Sure, a lot of front-ends do it, but sometimes you want to run MPlayer directly. For myself, it’s all about getting proper crop settings for DVD rips. But I’ve also had a few video files with incorrect or missing aspect ratio info.

Just put this into ~/.mplayer/input.conf:

F1 switch_ratio 0
F2 switch_ratio 1.3333
F3 switch_ratio 1.7778
F4 switch_ratio 1.85
F5 switch_ratio 2.3
