如何使用Windows内置的mp3解码器访问原始的解码音频数据？ [英] How to access raw decoded audio data using Windows' built in mp3 decoder?

问题描述

自Windows Media Player 6.1起，Windows拥有自己的mp3解码器。我可以使用该解码器访问解码的音频（原始）数据吗？

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?

我认为必须使用DirectShow。

I assume it would have to be done with DirectShow.

推荐答案

您可以添加样本采集卡插入mp3解码器之后的图形中。样本采集器允许您配置一个回调，该回调在每个样本通过媒体管道时被调用。

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.

您的图形看起来像

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