目前视频可以播放，但是音频不能是因为什么呀？
	MEDIA_FRAME_T pcm_frame;
	static RING_BUFFER_USER_HANDLE_T audioMainHandle = NULL;
	if(NULL == audioMainHandle)
	{	
		audioMainHandle = tuya_ipc_ring_buffer_open(0, 0, E_IPC_STREAM_AUDIO_MAIN, E_RBUF_WRITE);
		if(NULL == audioMainHandle)
		{
	        _logErr("RING_BUFFER_USER_HANDLE_T get audioMainHandle is NULL\n");
			return;
		}
	}
	pcm_frame.type = E_AUDIO_FRAME;
	pcm_frame.size = Len;
	pcm_frame.p_buf = pData;
	pcm_frame.pts = (FrameTimeStamp/1000);
	pcm_frame.timestamp= (FrameTimeStamp/1000);
	TUYA_APP_Put_Frame(audioMainHandle, &pcm_frame);
	
OPERATE_RET TUYA_APP_Put_Frame(RING_BUFFER_USER_HANDLE_T handle, IN CONST MEDIA_FRAME_T *p_frame)
{
    PR_TRACE("Put Frame. type:%d size:%u pts:%llu ts:%llu",
             p_frame->type, p_frame->size, p_frame->pts, p_frame->timestamp);

    OPERATE_RET ret = tuya_ipc_ring_buffer_append_data(handle,p_frame->p_buf, p_frame->size,p_frame->type,p_frame->pts);

    if(ret != OPRT_OK)
    {
        PR_ERR("Put Frame Fail.%d  type:%d size:%u pts:%llu ts:%llu",ret,
                  p_frame->type, p_frame->size, p_frame->pts, p_frame->timestamp);
    }
    return ret;
}
我们将传入的音频码流保存到sd卡中可以在电脑上直接播放有声音

这是ffmpeg对保存的音频文件的分析
