Broken performance between gst 1.10.0 and gst 1.14.4

I have an embedded device, based on "apalis-imx6" board.

Previously, I had an yocto Linux BSP image based on a "pyro" layer with the GStreamer v1.10.0.

using following pipeline to see the web-camera stream:

gst-launch-1.0 v4l2src ! image/jpeg,width=1920,height=1080,framerate=30/1 ! imxvpudec ! imxipuvideosink sync=false

I had the CPU load ~8 %

But, right now, after updating to the yocto layer "thud", with the GStreamer v1.14.4

I had the CPU load ~45%

A degradation is about 5-6 times... that is not acceptable.

UPD: Also I have created a bug: Unacceptable performance degradation between gst v1.10.0 and v1.14.4 · Issue #232 · Freescale/gstreamer-imx · GitHub 


So, is any workaround to fix this issue?
