我想在Rpsberry Pi上分发UVC摄像机的视频 我对/etc/ffserver.conf进行了如下编辑。
HTTPPort 8090
HTTPBindAddress 0.0.0.0
MaxHTTPConnections 20
MaxClients 10
MaxBandwidth 500000
CustomLog -

然后，我启动了ffserver 接下来，我执行了以下命令
ffmpeg -f v4l2 -s 1280x720 -i /dev/video0 -ac 1 -f alsa -i hw:1,0 http://localhost:8090/feed1.ffm
我从同一网络上的FireFox请求192.168.12.101：8090 / test.mpeg， 但没有显示视频，并且打开了要打开的程序或文件保存对话框。
我该怎么办？
