imxvpuenc_h264 comes from gstreamer-imx repository and rely on
downstream kernel (a Linux Kernel fork by NXP). v4l2h264enc is a
decoder based on standard Linux CODEC APIs (which in turn is base on
video4linux2 interface). To use this one, you'll need a mainline
kernel. It is a generic implement and you can use it on a wide amount
of embedded SoC running mainline Linux, notably Qualcomm Snapdragon,
Exynos 4/5+, Amlogic, IMX/Coda, etc.
