GLib.Error: gst_parse_error: no element "zbar" (1)
Following the answer to python gstreamer script error message no element "h264parse", I found zbar is a part of gst-plugins-bad, but I've already installed gst-plugins-bad 1.4.5-1. So why am I still getting this error?
I'm using Arch Linux, if it helps.
It's a bug in gst-plugins-bad Arch package. Just add zbar to depends in PKGBUILD, build it and install.
