处理视频库在Linux上不起作用（Ubuntu 13.04）

Question

I have a problem.

I'm trying to run the Mirror sample from the Processing video library, with the latest version of Processing (2.0.3). However, I get this error;

Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 14: reading configurations from ~/.fonts.conf is deprecated.
libEGL warning: failed to create a pipe screen for i965

This means I can't use video, of course. Any tips on fixing this?

Answer 1

You are missing the libgstreamer-0.10.so library, or it is not in the LD path. The most likely problem is that you have not installed the necessary packages from your distribution.

Answer 2

To elaborate on @JesseTG's comment:

For me, the necessary packages seemed to be the following:

$ sudo apt-get install gstreamer0.10 libgstreamer-plugins-base0.10-dev

The first package fixed the first link error, the second fixed the subsequent gstinterfaces link error.
