hverkuil: just to make sure we do get a small feedback from you at some point, in "Enumerate all pixels formats" addition, Benjamin and I had a little concern if there was something wrong of using the enum_fmt flags as an input, since it seems like it has never been used like this before, if that's wrong, some feeback would be welcome
ndufresne: how fun - the rate control in imx-vpu-hantro is semi broken - it does not model intra refresh correctly, and instead assumes that there are always IDR frames and GOPs
so now I am seriously considering to turn its rate control off and just do it myself with a PID controller and feed it the frame sizes
and while the imx-vpu-hantro code is available, it is tough to read
