I have a copy of the i.MX VPU Application Programming Interface Linux® Reference Manual from 03/2016. Is it current? Is it supported.
I ask because first although the manual says
VPU example application is located under Yocto Project build tmp work tree in imx-test/*/test/mxc_vpu_test
I can't find any such folder. And so after much searching I found a vpu_wrapper.h file but the structures and functions in it are named differently than in the programming manual above.
I hope there is a well documented and supported API for Linux user-space program to use the VPU for H.264 encoding/decoding.
