vlc will not play webcam.

#1 Postby rockets » Wed Sep 15, 2010 2:33 pm

I have mepis 8.5 installed on an amd 64 machine. vlc has always "just worked". Now it will not open the new webcam. I get the following error:

Code: Select all

Capture failed:
VLC cannot use the device "dsnoop:0", because its type is not supported.


I have reinstalled and upgraded vlc using the cr repos. Even tried aptitude (only removed a lib).

Running vlc from terminal gives video but no audio.

The problem with the CR version of VLC, described in the link above, was corrected up before September 15, when this thread was started.

@ rockets

You indicate that the updated version of VLC won't open your new webcam, but earlier versions always just worked in the past. Did earlier versions work with with the new webcam or with a different one? Maybe the upgraded version of VLC has a regression.

Unfortunately, I can't be much help troubleshooting your problem since I don't own a webcam and am running the 32-bit kernel.

We may be able to help if we have more specific info about the webcam. Please open Konsole and type:

Code: Select all

and report back the entry for it. If you have not looked, there is useful material (that needs updating) in the Wiki:

@ rockets

I think you need to downgrade VLC to version 1.0.6. In this post kmathern shows how to do it.

Another workaround is just to see if wxcam or guvcview will work with your cam. Both allow recording, too.

Sorry, for the delay...had to go fishing, had to help neighbor train dogs for field test...etc...

I probably should not have posted. I have a hand mic and a new (first time used) usb webcam.
a--skype plays video, but uses old hand mic not the usb webcam mic.

b--vlc refuses as stated if I click desktop icon, from terminal vlc plays video and complains of a alsa upgrade.

@joany: I have not tried vlc and webcam before. Sorry, I meant "vlc always just plays whatever I throw at it". btw-another mislead I am running a 32bit kernel on an amd64 chip.

@stevo: wxcam grabs the video but no audio.
