I have a Unifi UVC cam that I want to view on a website. I've been running ffmpeg to do that for some a few weeks. But no it wont work anymore. I can view the stream direct from the camera with unifyi Video. On the cam's IP. I can open the rtsp stream with vlc, but it breakes after a few second.

My ffserver.conf:

 Port 8090
# bind to all IPs aliased or not
BindAddress 0.0.0.0
# max number of simultaneous clients
MaxClients 1000
# max bandwidth per-client (kb/s)
MaxBandwidth 100000
# Suppress that if you want to launch ffserver as a daemon.
NoDaemon

<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 500M
</Feed>


<Stream test.mjpeg>
Feed feed1.ffm
Format mpjpeg
#VideoCodec mjpeg
VideoFrameRate 24
VideoBufferSize 80000
VideoBitRate 1016
VideoQMin 1
VideoQMax 5
VideoSize 1024x576
PreRoll 0
Noaudio
</Stream> 

My ffmpeg start syntax:

ffmpeg -rtsp_transport tcp -i "rtsp://user:pass@CAM-IP:554/s2" http://localhost:8090/feed1.ffm
