Gst-inspect not finding built plugins

Thu May 7 05:43:09 PDT 2015

Had this issue again on a different machine with similar characteristics.
Just reporting some new findings.

Setting the option --enable-shared when building libvpx from source seems
to be mandatory. Otherwise the libgstvpx.so gets built with 0 elements
inside.

Cheers
