我正在嘗試爲一個項目編寫一個簡單的流媒體服務器。我有一臺將運行ffserver的AWS Linux機器。 Curently,因爲它的立場,我的配置文件,如下所示:ffmpeg和ffserver,rc緩衝區下溢?

#Server Configs 
HTTPPort 8090 
HTTPBindAddress 0.0.0.0 
MaxHTTPConnections 2000 
MaxClients 1000 
MaxBandwidth 1000 
CustomLog - 

#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 
ACL allow <MY_PERSONAL_COMPUTER'S_PUBLIC_IP_HERE> 
</Feed> 

#Creates stream, allow everyone 
<Stream tagLive.mpg> 
Format mpeg 
Feed feed1.ffm 
VideoFrameRate 30 
VideoSize 640x480 
AudioSampleRate 44100 
</Stream> 

我然後我捕捉我的攝像頭,並使用以下命令將其發送到服務器:

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 

當我運行這個然而,我從我的控制檯得到以下輸出:

而在我的查看器上,我只是得到一個黑屏。

有什麼我失蹤了嗎?在「增加qmax」或類似於什麼ffmpeg抱怨的方面,搜索導致無所作爲。有人問過here,但沒有做任何事情。

在此先感謝
