[jitsi-users] Web Camera on LINUX


#1

I cannot see pictures of Web Camera when I use LINUX.

I can see pictures when I use Skype on LINUX.

I can see pictures when I use jitsi on Windows.

So the cause of failure is supposed to be in jitsi.

Dose anybody have the same problem?

Akira

i probably can't help you, but whoever might can, would probably need
more info from you, like:
which webcam
which linux (version and kernel version)
which jitsi version
possible error or warning messages in the jitsi log (or simply the
whole jitsi log in a pastebin)
