PJSIP/PJSUA2 -流AudioMediaPlayer / AudioMediaRecorder

Question

根据PJSIP/PJSUA2 documentation的说法，检索/发送音频数据的方法是使用AudioMediaRecorder/AudioMediaPlayer来对文件进行读写。

有没有办法通过流和缓冲区来做到这一点呢？

用户建议的解决方案：

http://www.pjsip.org/pjmedia/docs/html/group__audio__device__api.htm

启动音频流：

status = pjmedia_aud_stream_start(stream);

要停止流，请执行以下操作：

status = pjmedia_aud_stream_stop(stream);

要破坏这条流：

status = pjmedia_aud_stream_destroy(stream);

Info: The following shows how to retrieve the capability value of the stream (in this case, the current output volume setting).
// Volume setting is an unsigned integer showing the level in percent.
unsigned vol;
status = pjmedia_aud_stream_get_cap(stream,
PJMEDIA_AUD_DEV_CAP_OUTPUT_VOLUME_SETTING,
&vol);
Info: And following shows how to modify the capability value of the stream (in this case, the current output volume setting).
// Volume setting is an unsigned integer showing the level in percent.
unsigned vol = 50;
status = pjmedia_aud_stream_set_cap(stream,
PJMEDIA_AUD_DEV_CAP_OUTPUT_VOLUME_SETTING,
&vol);
