Conflicting with the mesa GL libraries.
Unfortunately, there some slight nuances with how the environment needs
to be set up which is not adhered to on the RPi or similar embedded
devices. There are a couple of options.
1. create a symlink from libGLESv2.so.1 in a directory pointed by
LD_LIBRARY_PATH to RPi's libGLESv2.so (and the same for libEGL.so)
2. recompile gst-plugins-bad with --with-egl-module-name and
--with-gles2-module-name pointing directly to the RPi libraries.
