quality-level property of omxh264enc missing

I want to improve performance by lowering the quality-level value of the omxh264enc. This worked well on the TX1, but on the TX2 this property seems to be missing. According to the “Accelerated GStreamer user guide 27.1” page 32, it should be there. But when I try to use it I get the error “object class ‘GstOMXH264Enc-omxh264enc’ has no property named ‘quality-level’”. When I use gst-inspect-1.0 to list all available properties “quality-level” is not there. How can I access this property?

Ok, I just found the solution: It has been renamed to “preset-level”.
