playing .nrg format dts cd with mplayer

Well, I was about to write about using cdemu to simulate a cd-device from an .nrg file, and then use mplayer to play the simulated device. It turns out you don’t even need cdemu if it’s a media cd/dvd image. Here’s the cli:

mplayer cdda:// -cdrom-device yourfile.nrg -rawaudio format=0x2001

the only mysterious part is the magic number 0x2001, telling mplayer the disc has dts rawaudio. Apparently you can find this number by man mplayer and search for dts.
