Cannot run demo on OSX using Homebrew

[johnthagen]

When I try to play a simple WAV file on OSX using the demo example I receive the following output:

/Users/hagenjt1/.cargo/bin/cargo run --example demo piano.wav
   Compiling sdl2_mixer v0.24.0 (file:///Users/hagenjt1/GitHub/rust-sdl2_mixer)
    Finished debug [unoptimized + debuginfo] target(s) in 0.44 secs
     Running `target/debug/examples/demo piano.wav`
linked version: 2.0.1
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "Mixer not built with Ogg Vorbis support"', ../src/libcore/result.rs:788
note: Run with `RUST_BACKTRACE=1` for a backtrace.
error: Process didn't exit successfully: `target/debug/examples/demo piano.wav` (exit code: 101)

Process finished with exit code 101

I've brew installed the following packages:

brew list --versions
sdl2 2.0.4
sdl2_mixer 2.0.1

Was there some kind of configuration step I've missed?

Environment:

• OSX 10.11.6
• Rust stable 1.12.1
• Cargo 0.13.0
• Homebrew 1.0.8

Can you post your brew info sdl2_mixer？

$ brew info sdl2_mixer

After doing some more research, it looks like the --with-flac, --with-fluid-synth, etc are probably needed?

I was able to get a .wav file to play using the following install:

$ brew install sdl2_mixer --with-flac --with-fluid-synth --with-libmikmod --with-libmodplug --with-libvorbis --with-smpeg2

brew list --versions
flac 1.3.1
fluid-synth 1.1.6
gettext 0.19.8.1
glib 2.50.1
libffi 3.0.13
libmikmod 3.3.8
libmodplug 0.8.8.5
libogg 1.3.2
libvorbis 1.3.5
pcre 8.39
pkg-config 0.29.1_2
sdl2 2.0.4
sdl2_mixer 2.0.1
smpeg2 2.0.0

Should this be the default way to install sdl2_mixer to work with rust-sdl2_mixer? If so, I'm happy to open a PR and update the README to help others.

👍 Yes, because default brew sdl2_mixer installation supports limited file formats.
A PR for updating README is welcome.
