This is quite ancient. About your deadlock, have you verified that the
fsl plugin (we don't support that one in general, because there is no
upstream) properly stop() or set_flushing() it's buffer pool when the
state change goes to READY (before you try to deactivate the pad) ?

p.s. You should probably use gst-plugins-imx and newer GStreamer
version. In 1.12, the vivante GL extension will be supported by
GStreamer upstream opengl plugin (no need for appsink).
