Hi guys
this evening I’ve been trying yo get a webcam working in Jitsi but no cam is detected I have 2 cams and both are the same, however they will both work in Cheese and VLC but refuse to work in Jitsi, Hello (the new firefox web based client) or Team Viewer that said Team Viewer will list them but is reporting them as in use by another application, but I have no idea what application that might be, I’m running Peppermint 5 64bit
Any help would be much appreciated
Graeme
With jitsi closed, try running
LD_PRELOAD=/usr/lib/X86_64-linux-gnu/libv4l/v4l1compat.so jitsi
or
LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so jitsi
did jitsi start and does the webcam work ?
if that doesn’t work, post the output from:
locate v4l1compat.so
Jitsi opened ok but still no cam

Try:
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so jitsi
Once again Jitsi opened up but no devices detected here’s the output

Is the webcam recognised in Skype … and if so, if you open Skype BEFORE opening Jitsi (both running but Skype first) is the webcan then detected by Jitsi ?
Skype is not detecting the webcam either
Graeme
Does skype recognise it if you start skype with:
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so skype
?
Skype is detecting the webcams but not playing anything, Jitsi is still not detecting any devices

Jitsi is a Java app isn’t it ?
which java RE are you using … openjava or the Oracle Java runtime environment
What’s the output from:
update-alternatives --display java
What happens if you (with Jitsi closed) run cheese … then with Cheese open start Jitsi … then in jitsi go to
Tools > Options > Video > Devices tab
is anything listed in the “Camera” drop menu ?
graeme@Linux1 ~ $ update-alternatives --display java
java - auto mode

Still not listing any devices, I did try this earlier and it’s the same with VLC
Thanks for your patience
