Crashes when using SDL.OpenAudio directly

[rhp]

Hi,

I am trying to set-up a program in which I use SDL to play some sound from a pre-loaded buffer. Using the callback method for OpenAudio gives me some trouble: it crashes after running through a few loops of the callback method.

See this example:

#! /usr/bin/ruby -w

require 'rubygems'
require 'ruby-sdl-ffi'

SDL.Init(SDL::INIT_AUDIO)

spec = 
    SDL::AudioSpec.new(
        :freq => 22100,
        :format => SDL::AUDIO_S16,
        :channels => 2,
    :silence => 0,
        :samples => 512,
    :padding => 0,
    :size => 0,
        :userdata => nil,
        :callback => Proc.new { |unused, stream, len|
            p stream
            p len
        }
    )

raise "Could not open SDL audio" if SDL.OpenAudio(spec, nil) < 0

SDL.PauseAudio(0)

loop do
    SDL.PollEvent do |event|
        case event
            when SDL::QuitEvent
            exit(0)
            else
                # Do nothing
        end
    end
end

Auch... that didn't go entirely right... But I think you get the point...

Hi. This library is still very young, so things are expected not to work. Thanks for the report though, I'll be sure to fix it in the future.

As a workaround until this is fixed, I would suggest using SDL::Mixer::OpenAudio instead, if you don't need all the advanced AudioSpec stuff.
