FFmpeg本机AAC解码器 [英] FFmpeg native AAC decoder

问题描述

我正在Windows上使用商业C ++ C ++应用程序，需要解码AAC。我看过这个问题 AAC编解码器库（libFAAC替代）
从答案看，FFmpeg似乎有一个原生的LGPL AAC解码器。但是，当我看到FFmpeg主页时，我没有找到关于该解码器或者它支持的AAC对象类型的信息（仅关于编码器的信息）。我一直在寻找这个2天，但我几乎找不到任何东西。所以我的问题是：

1. 本机FFmpeg AAC解码器支持或甚至存在什么类型的对象类型？


2. 如果上述解码器不存在，那么是否有任何可选的免费库？我也看过FDK AAC，但是我不明白它的许可证，我可以用它做商业产品吗？

请帮助我更新音频编解码器。

解决方案

本机FFmpeg AAC解码器支持什么类型的对象类型或
甚至存在？

我不知道这是什么意思。我不认为这是正确的英语。

我将假设您的问题是：FFmpeg是否包含本机，LGPLv2.1 AAC解码器，如果那么它支持什么比特流功能呢？第一个问题的答案是肯定的。它位于这里在代码库中。支持的功能列在这里（虽然该列表可能有些过时）。如果您对支持的比特流功能有更多的具体问题，请问这里，我会看到我能记住的内容。

I'm working on a commercial C\C++ app on Windows that need to decode AAC. I have looked at this question AAC Codec Library (libFAAC alternative) From the answer, it seems that FFmpeg has a native LGPL AAC decoder. However, when I looked at FFmpeg home page, I found no information about this decoder or what AAC object type it supports (only information about encoder). I have been searching for this for 2 days but I found almost nothing. So my questions are:

1. What type of object type does native FFmpeg AAC decoder support or does it even exist?
2. If the above decoder does not exist then is there any alternative free library? I have also looked at FDK AAC but I don't understand its license, can I use it for commercial product?

Please help I'm new to audio codec.

解决方案

What type of object type does native FFmpeg AAC decoder support or does it even exist?

I have no idea what that means. I don't think this is proper English.

I'm going to assume that your question is: does FFmpeg include a native, LGPLv2.1 AAC decoder, and if so, what bitstream features does it support? The answer to the first question is yes. It's located here in the codebase. Supported features are listed here (although that list is likely somewhat outdated). If you have more specific questions about supported bitstream features, ask here and I'll see what I can remember.
