On my x86_64 (OpenSUSE-13.2) host build the libs and libimxvpuapi.pc
are installed into $(STAGING_DIR)/usr/lib64 and $(TARGET_DIR)/usr/lib64.

To be usable by eg. gst1-imx the install path should be $(STAGING_DIR)/usr/lib
and $(TARGET_DIR)/usr/lib. To achieve this I added '--libdir=/usr/lib' to
overwrite the default '/usr/lib64':

With this you can add my

Tested-by: Peter Seiderer <ps.report@gmx.net>

for '...! imxvpudec ! imxipuvideosink'

But I had problems using the imxeglvivsink element and
with qt5 eglfs, suspecting your 'Update most Freescale packages' patch series
(using buildroot-2016.02-rc1 with your '[PATCH v3 0/2] gst1-imx: bump version to 0.12.0'
patches on top), but did not find time yet to investigate further...

Regards,
Peter
