video encoder using mainline kernel

[jpm]

Has anyone managed to get video encoder working with the latest mainline kernel?

 

I'm getting stuck trying to compile the cedar_ve kernel driver from https://github.com/uboborov/sunxi-cedar-mainline

 

I have downloaded the kernel source using armbian-config and then built the sunxi-cedar-mainline kernel driver. However, I fail to load the driver due to version magic:

Quote

root@nanopineo:~# modprobe cedar_ve
modprobe: ERROR: could not insert 'cedar_ve': Exec format error
root@nanopineo:~# dmesg | tail -n 1
[  653.998366] cedar_ve: version magic '5.15.80 SMP mod_unload ARMv7 thumb2 p2v8 ' should be '5.15.80-sunxi SMP mod_unload ARMv7 thumb2 p2v8 '

 

When trying to force the load:

Quote

root@nanopineo:~# modprobe -f cedar_ve
modprobe: ERROR: could not insert 'cedar_ve': Exec format error

 

But no dmesg message about magic check failure.

Some updates:

1) Updated the dts file as required in https://github.com/uboborov/sunxi-cedar-mainline

2) Fixed cedar_ve compilation issues / kernel name

3) after loading the cedar_ve.ko, get only this is dmesg:

[   71.096286] cedar_ve: loading out-of-tree module taints kernel.
[   71.097176] cedar_ve: module verification failed: signature and/or required key missing - tainting kernel
[   71.098546] sunxi cedar version 0.1

 

@ubobrov I would appreciate any insights.

@ning Thanks for the link. But if I understand correctly - this is for decode. I need to encode h264.
