PJSIP/PJSUA2 - 流 AudioMediaPlayer / AudioMediaRecorder

Question

根据PJSIP/PJSUA2 documentation，获取/发送音频数据的方法是使用AudioMediaRecorder/AudioMediaPlayer 向/从文件写入/读取数据。

有没有办法用流和缓冲区做到这一点？

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：

status = pjmedia_aud_stream_stop(stream);

并销毁流：

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);
