[GD-Windows] DShow / DMusic and MP3

[Nicolas R. <nic...@fr...>]

Hi !

I'm trying to implement mp3 support for background music in our engine (for
now only midi and dmus were supported), was wondering what you guys feel
more comfortable with:

1- Entirely going through DShow (using default audio output).

2- Using DShow for mp3 streaming/reading/decoding, using a in-house
audio-renderer for interaction with DMusic/DSound

3- Using a custom mp3 decoder, using DMusic only for rendering.

(knowing that DMusic is used for 3D sound in parallel).

We're using Ogg-Vorbis and are _extremely_ pleased with it.

Thanks...

I'll probably try to make .ogg files supported, but i'm really asked to support .mp3
unfortunately :)

And the same question (DShow-only, DShow->DMusic, own->DMusic) applies to .ogg files as
well...

The answer to your original question in what relates to Ogg-Vorbis is,
external decoder that sends sample stream to DSound (DMusic?).

When we were originally using MP3 we had DShow decode the stream into a
filter buffer, which we would read and send to DSound. Wasn't very pretty,
but then, nothing DShow-related is.
