ffmpeg 및 ffserver, rc 버퍼 언더 플로?

프로젝트의 간단한 스트리밍 서버를 작성하려고합니다. ffserver을 실행할 AWS Linux 시스템이 있습니다. 이 약자로 Curently, 내 설정 파일처럼 보이는 다음ffmpeg 및 ffserver, rc 버퍼 언더 플로?

#Create a Status Page 
<Stream stat.html> 
Format status 
ACL allow localhost 
ACL allow 255.255.255.255 #Allow everyone to view status, for now 
</Stream> 

#Creates feed, only allow from self 
<Feed feed1.ffm> 
File /tmp/feed1.ffm 
FileMaxSize 50M 
ACL allow 127.0.0.1

<Stream tagLive.mpg> 
Format mpeg 
Feed feed1.ffm 
VideoFrameRate 30

</Stream>

그때 내 웹캠을 캡처하고 다음 명령을 사용하여 서버에 그것을 보낸다 :

ffmpeg -f dshow 
     -i video="Webcam C170":audio="Microphone (Webcam C170)" 
     -b:v 1400k 
     -maxrate 2400k 
     -bufsize 1200k 
     -ab 64k 
     -s 640x480 
     -ac 1 
     -ar 44100 
     -y http://<AWS_SERVER_PUBLIC_DNS>:8090/feed1.ffm

내가 이것을 실행 그러나 내 콘솔에서 다음과 같은 출력을 얻습니다.

내가 누락 된 자료가 있습니까? 검색은 "증가하는 qmax"또는 무엇이든 ffmpeg에 대해 불평과 비슷한 것을 유도합니다. here에 대한 질문이 있지만 아무 것도 끝나지 않았거나 답변되었습니다. 사전에

덕분에

당신은 서버 설정에서 Qmax의 및 qmin을 설정할 수 있습니다

<Stream test_3840.flv> 
... 
VideoQMin 1 
VideoQMax 15 
... 
</Stream>
