在java中解析ogg文件而不解码
我有一个 .spx 文件（带有 Speex 编码音频的 Ogg 文件）。我想使用 Java 将 Speex 编码的字节从 Ogg 容器中提取出来。
问题是，似乎我能找到的所有 Java 库（JSpeex、JOrbis）都是假设我还想将音频解码为原始 pcm ，我不知道。
是否有适用于 Java 的通用 Ogg 格式阅读器库？另一方面，是否可以使用 JSpeex 或 JOrbis 的部分来完成我想要的操作？
I have a .spx file (an Ogg file with Speex-encoded audio). I would like to use Java to pull the Speex-encoded bytes out of the Ogg container.
The problem is, it seems all of the Java libraries I can find (JSpeex, JOrbis) are written with the assumption that I would also like to decode the audio into raw pcm, which I do not.
Is there a generic Ogg format reader library out there for Java? On the other hand, is it possible to use parts of JSpeex or JOrbis to do what I want?

经过一些浅层搜索后，我找不到 Java 中的 Ogg 库。
但如果你愿意从头开始实现 Ogg 解析，直接从马口中出来的话就很容易获得：

I could not find an Ogg library in Java after some shallow searching.
But if you are willing to implement Ogg parsing from scratch, the words straight from the horse's mouth are readily available:

我没有使用过带有 Speex 编码音频的 Ogg 文件，但是一旦我处理了一个用例，我想从 ogg opus 文件中提取 opus 数据包，而不被解码为 pcm 音频。您可以在此答案中找到该解决方案

这段代码也适用于带有 vorbis 编码的 ogg 文件，因此这可能也有助于 speex 编码。请告诉我这是否适合您。
快乐编码!!!❤
I have not worked with Ogg file with Speex-encoded audio but once I have worked on a use case where I wanted to extract opus packets from ogg opus file, without being decoded to pcm audio. You can find that solution in this answer

This piece of code also works for ogg file with vorbis encoding, so may be this might help with speex encoding as well. Do let me know if this works for you.
Happy Coding!!!❤
