--- Comment #3 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
See above, you either need to implement GstVideoOverlayComposition (and you
need GStreamer 1.6 or better 1.8 for this to work properly), or use glimagesink
(which needs special integration work to be done to work with imx6, and also
1.6 or 1.8).

There's nothing that can be done on our side here, it's something that has to
be solved in the imx6 elements. The problem is that because of the textoverlay
element, whenever there are subtitles the video frames have to be handled by
the CPU and downloaded from the GPU and uploaded again. That's slow.
