Use GStreamer 1.x, decodebin prevents plugging infinitely the same
But independent of that, your decrypter element should accept different
caps on the sinkpad than it outputs on the srcpad. E.g.
"application/x-martins-encryption" vs "video/h264". Then there should be
no infinite loop of the same element.
