When I try the last command in VlC like : 

cvlc rtsp://192.168.1.104

I got :

Where do I have to look to resolve this bug ? Many thanks for this greatfull app.

Looks like your server runs on port 8888 - you need to specify port for cvlc

(VLC uses 554 as default)

Thanks, your right but when I have corrected this mistake I got :

 cvlc rtsp://192.168.1.104:8888/unicast

I will at least use the flux in motion eyes wich say : "unable to open video device"...

AFICR, there is no audio for this setup (Streaming a Raspberry Pi camera)

It would be better if the server created a “dummy” mp3 audio track, since one could then forward to for instance YouTube, which REQUIRES an audio track in the stream.

The raspberry pi do not have access to Internet. Is it possible to disable sound support ? The system works well with a rpi with internet access I copy the card on another change the ip adress and the rpi refuse all connexion rstp.

The systemctl status is different :

systemctl status v4l2rtspserver.service

Hi,

Based on the command you used to start (using -P8888), you should be able to reach the stream with cvlc rtsp://192.168.1.104:8888/unicast. Acessing internet doesnot matter, I did not understand what involve internet using RTSP streming with an ip address. To disable audio, you may try to run :

v4l2rtspserver -H 1200 -W 1600 -F 60 -P 8888 /dev/video0,

(coma at the end says to not add an audio stream, by default it looks for an audio link to the video device)

Best Regards, Michel.

Hi, I have try to edit the /usr/lib/systemd/system/v4l2rtspserver.service like this :

[Unit]
Description=V4L2 RTSP server
After=network.target

[Service]
Type=simple
Restart=always
RestartSec=5
ExecStart=/usr/local/bin/v4l2rtspserver -H 1200 -W 1600 -F 60 -P 8888 /dev/video0,
WorkingDirectory=/usr/local/share/v4l2rtspserver

[Install]
WantedBy=multi-user.target

Without coma all works at a first time like this :

systemctl status v4l2rtspserver.service 
Warning: The unit file, source configuration file or drop-ins of v4l2rtspserver.service changed on disk. Run 'systemctl daemon-reload' to reload units.

After reload and restart I get this message :

And no more camera. Have I made something wrong ?
