MJPEG Camera Stream

[bzbit]

I have a DLink DCS-932L Camera. It provides an MJPEG stream over HTTP.

When I attempt to open the camera using VLC I use the following syntax in the 'open network stream' box:

http://user:pass@xxx.xxx.xxx.xxx:80/mjpeg.cgi

VLC successfully connects to the camera but when the data starts to stream VLC reports:

EOF Reached

before I see anything.
BTW: This same thing happens in VLC 1.1.11 and VLC 2.0.

If I use FFMPEG to open the camera I get all the data properly...but I'd rather use VLC.

Anyone have any suggestions?

[Sébastien Escudier]

show the logs (vlc -vv or verbosity=2) but I think it will be hard to tell without the stream to test.

here is the log...I have obscured the usernames/passwords and inet addresses also since I kept getting the error 'your message contains too many URL's I had to replace the URLS's with the text 'URL'

[Sébastien Escudier]

how did you launch this stream, what option did you pass to vlc ?

[bzbit]

I didn't pass any options to VLC. I just opened the GUI and used the 'open network stream' from the 'Media' menu:

in the text box, I typed:

http://user:pass@xxx.xxx.xxx.xxx:80/mjpeg.cgi

[Sébastien Escudier]

Then I don't know.
If you can, provide me a link to your camera and I will have a look.
