Commandline MPlayer on OS X
The OS X build of Mplayer (from the official site) does have good old mplayer buried in it; it’s at
It may also be at
/Applications/MPlayer OS X 2.app/Contents/Resources/mplayer.app/Contents/MacOS/mplayer
on other builds.
Found it thanks to this blog.
Also, the OSD (subtitles, fonts) by default doesn’t “just work” on OS X; you have to symlink a ttf file into ~/.mplayer/subfont.ttf
There are some TTF fonts in /Library/Fonts/; you can try
locate .ttf to find more. (Or download, of course.)
