Page 9: Gstreamer Function
From PD16.1.0 up to PD17.1.1 the GStreamer contains the " imxpxpvideosink use-vsync=tru" plugin. This plugin reduce the tearing. Most of the Phytec GStreamer example scripts use this plugin. Please show the scripts in path ../gstreamer_examples/.. . For more information to "imxpxpvideosink" parameters type: - gst-inspect-1.0 imxpxpvideosink... -
Page 10: Bayering (Demosaicking) With Neon Coprocessor
If the microprocessor does not include debayering hardware, have to do the converting via software. For this you need additional processing power and the framerate goes down. It is better to use the NEON coprocessor of the i.MX6. For this support PHYTEC a special function.
