Description j-frankish 2014-05-27 06:54:26 UTC

cheese-3.10.2 and 3.12.2 will not start due to an apparent problem with the video effect "Time delay".

Note that guvcview and "gst-launch-1.0 v4l2src ! xvimagesink" work on the same machine.

Using gst-plugins-bad-1.2.4

Shouldn't cheese start even if some video effects do not work?

Seems like this was fixed locally according to https://mail.gnome.org/archives/cheese-list/2014-May/msg00023.html

Comment 2 j-frankish 2014-05-31 11:42:52 UTC

No, I was unable to get to that stage without first sorting out the gnome-video-effects problem.

A problem with video effects should not prevent cheese from starting.
