我真的很希望有，但是没有，至少到ICS。

果冻豆提供了一个媒体codeC 类。虽然它并没有给我的支持codeCS清单，它确实有 createEn coderByType（），在那里你传递一个MIME类型。 presumably，这将抛出一个的RuntimeException 或返回空如果不支持所需的MIME类型。我不能答应，仅仅因为媒体codeC 报道说，一间codeR可用，它是保证，比如说， MediaRecorder 。

Is there a way to ask an Android device what audio and video Codecs it supports for encoding?

I found devices that do not support some of the codecs listed as mandatory in http://developer.android.com/guide/appendix/media-formats.html and there seem to be devices supporting additional codec not listed there.

I really wish there were, but there is not, at least through ICS.

Jelly Bean offers a MediaCodec class. While it does not have a "give me a list of supported codecs", it does have createEncoderByType(), where you pass in a MIME type. Presumably, that will throw a RuntimeException or return null if your desired MIME type is not supported. And I cannot promise that just because MediaCodec reports that an encoder is available that it is guaranteed to work from, say, MediaRecorder.
