推荐答案

从所有我能找到API文档，你不能改变的EN $ C $铬。唯一的EN codeR设置我能找到，你可以改变是：

From all I can find on the API documentation, you can't change the encoder. The only encoder settings I could find that you can change are:

AVEncoderAudioQualityKey;
AVEncoderBitRateKey;
AVEncoderBitDepthHintKey;

至于在传输文件，一个典型的方法是通过电子邮件发送该文件。

As for transferring the file, a typical approach would be to email the file.
