Потоковая передача с помощью ffserver и ffmpeg на RaspberryPi

/ 15 сентября 2018

Я хочу передать видео с камеры UVC на Rpsberry Pi. Я отредактировал /etc/ffserver.conf следующим образом. 

HTTPPort 8090
HTTPBindAddress 0.0.0.0
MaxHTTPConnections 20
MaxClients 10
MaxBandwidth 500000
CustomLog -

<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 50M
</Feed>

<Stream index.html>
Format status
ACL allow 192.168.12.0 192.168.12.255
</Stream>

<Stream test.mpeg>
Feed feed1.ffm
Format mpeg
VideoSize hd720
VideoFrameRate 15
VideoBitRate 4096
VideoBufferSize 4096
VideoQMin 5
VideoQMax 51
Strict -1
</Stream>

Затем я запустил ffserver. Затем я выполнил следующую команду * 1004.* 

ffmpeg -f v4l2 -s 1280x720 -i /dev/video0 -ac 1 -f alsa -i hw:1,0 http://localhost:8090/feed1.ffm

Я запросил 192.168.12.101: 8090 / test.mpeg из FireFox в той же сети, но видео не отображается и открывается программа или открывается диалог сохранения файла.

Что следуетЯ делаю?
