  1. @ubobrov Really big thanks, I have spend a lot of time to force Orange Pi Zero encode video with no luck. With you instruction I got a chance to make it works. Tried to do the same as you wrote step-by-step carefully, but kernel module fails with the error in `dmesg`: ``` [ 0.000000] Reserved memory: created CMA memory pool at 0x4a000000, size 96 MiB ... [ 1948.521206] sunxi_cedar: loading out-of-tree module taints kernel. [ 1948.522324] sunxi cedar version 0.1 [ 1948.522598] [cedar]: install start!!!

Thanks.
