Hi,
Using SabreSD with i.MX6Q and Linux 4.0.0 SDK.
I know that there is hardware on the IPU for hardware colorspace conversion because there is a gstreamer component for it in libmfw_gst_ipu_csc.so. I was wondering what libraries provide support for access to this hw colorspace conversion.
Do openGL and directfb that are provided with the SDK give access to hw colorspace conversion?
I am trying to improve performance of mplayer for software decoding of intra-refresh h.264 streams. Right now colorspace conversion is in software and I'd like to do this in hardware for better video playback performance.
Thanks.

Is libipu not available for i.MX6Q? It looks like a dummy version gets compiled for i.MX6Q platform (I am looking at imx-lib-3.0.35-4.0.0/ipu/Makefile).
What are the alternatives? Use linux/ipu.h IOCTLs?
