如何使用Windows内置的mp3解码器访问原始解码音频数据？

Question

Since Windows Media Player 6.1, Windows has its' own mp3 decoder. Can I use that decoder to get access to the decoded audio (raw) data?

I assume it would have to be done with DirectShow.

Answer 1

You can add a sample grabber into the graph after the mp3 decoder. The sample grabber allows you to configure a callback that gets called as each sample passes through the media pipeline.

Your graph would look something like

mp3 file -> mp3 decoder -> sample grabber -> renderer
