Actually I was getting a much worse error before ;/ I can't remember it
now.

Basically all I did was change the sink:
sink = ElementFactory.make("autoaudiosink", "auto-output");
So it I could get past the error about alsa. I think the last name
doesn't matter?
I downloaded the gstreamer binaries from their site, had some issues
with a few of the dll's complaining about gxx errors, I removed
them(h264, soundtouch, tag).
For the wav I changed
//parser = ElementFactory.make("oggdemux", "ogg-parser");
//decoder = ElementFactory.make("vorbisdec", "vorbis-decoder");
parser = ElementFactory.make("wavparse", "wav-parser");
decoder = ElementFactory.make("audioconvert", "wav-decoder");
which, is all i could find on line, I don't know if it's right at all.
Ultimately I want to be able to read somewhat arbitrary audio
formats(most common at least), get the raw channel data(samples for each
channel), play/pause/stop with good accuracy(no latency or low
latency(<20ms), possibly do some pitch shifting and basic mixing(EQ,
limiting, panning, etc), and eventually play some videos.
Is GstreamerD going to be useful for this or so I look in to using
ffmpeg directly and do some of the stuff(e.g., eq) myself?
Thanks.
The Gstreamer demo should use an `playbin` instead of explicitly setting
the pipeline, Like this:
https://github.com/gtkd-developers/GtkD/blob/master/demos/gstreamer/helloworld/gstreamer_helloworld.d
This way gstreamer will detect the file type, i don't know if it helps
with the errors.
