[jitsi-users] Video Fails HP Truevision HD


#1

Hello,

Has anyone been able to get video to display in Jitsi with the HP
17-G188CA laptop?

Computer: HP 17-G188CA
OS: Linux / Ubuntu 14.04 using Mate 1.8.2
Java: OpenJRE 7 and Oracle Java 1.8.0_6 (both unsuccessful)
Jitsi 2.5, 2.6 and 2.9.5487 - all fail

In Jitsi Tools | Options | Video | Devices, I see the built-in camera
and a Logitech USB webcam. Enabling video turns on the 'record' light
for both cameras, yet no image.

I had the same hard disk in an Acer laptop and everything was working
perfectly. Hence, likely a hardware issue.

Skype, VLC and Cheese work perfectly on the HP laptop with both cameras.

Hello,

Update: Fixed by installing the closed-source AMD Catalyst drivers and
not using the open-source versions.

Thanks,
Mark
