not able to get vlc working

[UnknownX]

Hi@ll,

after serveral days (and nights) of trying to get vlc working I'm giving up now.

First of all it is a debian lenny machine I am talking about. In this enviroment I was running in trouble with ffmepg so I decided to update the machine to "testing" where the "problems" are looking a bit different.

What I want to solve in general is to stream a webcam connected locally via usb to a zoneminder server. At this time I'm not quite sure of the right output but think that the following entry could not be wrong in general:


Here are the latest results:

vlc -vvv v4l:/dev/video0:size="320x240" --sout #transcode{vcodec=mp4v,venc=ffmpeg}:rtp{dst=192.168.110.232,port=1234,sdp=http://192.168.110.232:8080/test.sdp}' --no-audio --ttl 1

After this vlc replies as follows:

As you maybe can think vlc is installed by a preconfigured .deb package. On the machine itself should run nothing more than vlc so if it would be a good suggestion to change the debian version or the system itself this would be no problem - but on the other side I am quite sure that there is anyone out who can help before doing such a step.

So if you have any hints for me to make vlc running I'll be very thankful

regards
Stefan

Many thanks for your help !

[UnknownX]

nobody with any hints ???

regards

[xtophe]

Try with the v4l2 module rather than v4l

[UnknownX]

Dear @ll,

thanks for your reply "xtophe".

If I use the v4l2 module the message is a bit different - but still not working. In this case I'm (and furthermore the vlc player is) not able to open the stream.

Anyone with any suggestion for this case?

The command for this result was cvlc -vvv v4l2:///dev/video0:height=480:width=640

Is that on sid ?

Try with --v4l2-use-libv4l2
