1.鏈接說明

ms_filter_link(stream->soundread,0,stream->ec,0); ms_filter_link(stream->ec,0,stream->encoder,0); //inputs[0] 將數據鏈接到0 ms_filter_link(stream->decoder,0,stream->ec,1); ms_filter_link(stream->ec,1,stream->soundwrite,0); //inputs[1]將數據鏈接到1

2.數據讀取

while((tmp=ms_queue_get(f->inputs[1]))!=NULL){//拿回inputs[1]數據 是從soundread來的log_error("save_voice tmp.pcm");inputlen=msgdsize(tmp);memcpy(tmpinput,tmp->b_rptr,inputlen);save_voice(voicetmp,tmpinput,inputlen);//save_voice(voicetmp,tmp->b_rptr,msgdsize(tmp));ile++;ce=allocb(inputlen,0);memcpy(ce->b_rptr, tmp->b_rptr, inputlen);ce->b_wptr+=inputlen;ms_queue_put(f->outputs[1],ce);freemsg(tmp); }while((im=ms_queue_get(f->inputs[0]))!=NULL){int len=msgdsize(im); //拿回inputs[0]數據 是從decoder來的

3.接口說明

MSFilterDesc ms_webrtc_aec_desc={MS_WEBRTC_AEC_ID,"MSWebRTCAEC","Echo canceller using WebRTC library.",MS_FILTER_OTHER,"AEC",2, //兩進兩出 ipnuts[0]和inputs[1]2,webrtc_aec_init,webrtc_aec_preprocess,webrtc_aec_process,webrtc_aec_postprocess,webrtc_aec_uninit,webrtc_aec_methods,0 };
